00:00:00.660 --> 00:00:07.920
hey everyone Sal here and I wanted to show you an
in-depth demo of the new AI that we have happening

00:00:07.920 --> 00:00:14.040
throughout Khan Academy and what you're going to
see is that it exists in two ways one is helping

00:00:14.040 --> 00:00:18.360
students and Learners and teachers with many
of the things that people already familiar with

00:00:18.360 --> 00:00:23.820
Khan Academy and as we'll see also introducing a
whole new series of activities that you can now

00:00:23.820 --> 00:00:29.280
do with the artificial intelligence so what I see
here what we see here is a classic Khan Academy

00:00:29.280 --> 00:00:35.580
exercise but you notice there's this little bot
here so we could click on that I'm here to help

00:00:35.580 --> 00:00:39.720
you with this exercise here are a few ideas or
things that you can ask me and you could ask

00:00:39.720 --> 00:00:44.580
any of those things but I think what's really
interesting is its ability to be a thoughtful

00:00:44.580 --> 00:00:51.780
tutor so if I just say tell me tell me the
answer exclamation mark I'm very entitled here

00:00:52.680 --> 00:00:56.520
oh I see you're eager to find the answer but
remember I'm here to help you learn how to

00:00:56.520 --> 00:00:59.640
solve it on your own let's start by looking at
the equation what do you think the first step

00:00:59.640 --> 00:01:02.940
should be so notice it's really doing what
you would expect a good tutor to be and let

00:01:02.940 --> 00:01:06.540
me actually do a mistake here so let's do
three minus this is a common mistake when

00:01:06.540 --> 00:01:13.380
Distributing only multiplying it times the
first term minus 18 plus 2m is equal to m

00:01:15.240 --> 00:01:20.760
it says oops it looks like there's a small
mistake when you distributed the negative

00:01:20.760 --> 00:01:25.860
2 inside the parentheses I put an upside down
smiley face make sure you distribute the negative

00:01:25.860 --> 00:01:29.880
2 to both terms in the parentheses the correct
distribution would be this try again let me know

00:01:30.480 --> 00:01:39.300
if you need help you got this and then if I
were to write 3 minus 18 minus 4M is equal to m

00:01:40.320 --> 00:01:45.000
great job you distributed the negative 2 correctly
this time now you have the following what do you

00:01:45.000 --> 00:01:50.520
think the next step should be to solve for M so as
you can tell this is really doing what we think a

00:01:50.520 --> 00:01:55.980
really thoughtful tutor would do and this doesn't
just work in math this works across all subjects

00:01:55.980 --> 00:02:01.440
that Khan Academy has now it's not just exercises
this is going to sound like an infomercial I'm

00:02:01.440 --> 00:02:07.680
going to keep saying and there's more you could do
with this with videos this is just a classic Khan

00:02:07.680 --> 00:02:14.280
Academy video that hopefully many of y'all are
familiar with you can do fun things like write

00:02:14.280 --> 00:02:21.660
a poem about this video and so notice in both the
previous example where it uh it where I got help

00:02:21.660 --> 00:02:25.260
with the problem it already had the context of
the problem it knows what I'm already doing on

00:02:25.260 --> 00:02:30.540
Khan Academy likewise here it already knows about
the video it's able to understand what's actually

00:02:30.540 --> 00:02:35.280
in the contents of the video it wrote a very nice
poem here in the land of math where equations play

00:02:35.280 --> 00:02:42.300
a problem arose one sunny day negative nine minus
9x minus six a challenge to solve a puzzle to fix

00:02:42.300 --> 00:02:46.680
on the other hand that's actually as you can see
here that's actually the actual problem that is in

00:02:46.680 --> 00:02:53.700
this video on the other side 3 times 4X plus 6 we
must simplify with our math tricks distribute we

00:02:53.700 --> 00:02:59.100
must and combine like terms too to find the value
of x that's what we will do and it keeps going on

00:02:59.100 --> 00:03:06.480
so that's fun but there's other things you could
do you could say why do I need to learn this

00:03:11.640 --> 00:03:16.080
and it asks what are your interests or
goals knowing that will help me explain

00:03:16.080 --> 00:03:25.800
how this math concept might be relevant to
you say I really love I don't know soccer

00:03:28.980 --> 00:03:35.340
see what it says great in soccer math can
be quite useful especially when analyzing

00:03:35.340 --> 00:03:39.420
player performance game statistics and team
strategies understanding equations like the one

00:03:39.420 --> 00:03:43.440
in the video can help you grasp more advanced
math concepts which can be applied to soccer

00:03:43.440 --> 00:03:47.880
analytics predicting player movements and even
optimizing training routines so learning this is

00:03:47.880 --> 00:03:53.400
this math concept can enhance your understanding
and appreciation of the beautiful game and gotta

00:03:53.400 --> 00:03:57.840
love the Emojis is doing here so this is
once again across all the videos all the

00:03:57.840 --> 00:04:02.640
Articles all the exercises on Khan Academy you can
either you can even do things like this quiz me

00:04:03.840 --> 00:04:09.060
and obviously Khan Academy already has a lot of
exercises but here we can just do more and this

00:04:09.060 --> 00:04:15.960
is directly related to uh what's going on in the
video but now you know we've just shown how the AI

00:04:15.960 --> 00:04:21.120
can be helpful with things that people are already
used to doing on Khan Academy I'll now show how it

00:04:21.120 --> 00:04:27.600
can be useful for introducing a whole new series
of activities that uh some of which I think would

00:04:27.600 --> 00:04:32.520
have looked like science fiction even a few months
ago so I'm logged in right now as a teacher and

00:04:32.520 --> 00:04:37.320
you can see a couple of interesting things here
you can see activities for teachers and you can

00:04:37.320 --> 00:04:43.320
also see activities for Learners and we already
have a bunch and we're going to be adding more in

00:04:43.320 --> 00:04:47.340
the weeks and months to come but one really
interesting thing and this is an important

00:04:47.340 --> 00:04:52.800
safety is you see it says this conversation
is recorded and viewable by your teacher

00:04:52.800 --> 00:04:57.540
and we're doing that and if there's a parent
attached to this account it'll say recorded

00:04:57.540 --> 00:05:01.800
and viewable by your teacher and your parent or
or your parent and the whole point of that is we

00:05:01.800 --> 00:05:06.420
know that the that artificial intelligence large
language models has a lot of power and it can be a

00:05:06.420 --> 00:05:10.200
really powerful learning tool as I'm about to show
you but we also want to make sure that there's

00:05:10.200 --> 00:05:15.720
proper guard rails we've put a lot of guard
rails into the actual tool we're also being very

00:05:15.720 --> 00:05:21.540
careful where we're not passing any personally
identifiable information to the actual artificial

00:05:21.540 --> 00:05:28.380
intelligence we are also not using student data
to train it so parents teachers students can rest

00:05:28.380 --> 00:05:33.360
assured that this is as safe of an environment
as we can create we're also putting guard rails

00:05:33.360 --> 00:05:39.300
around the activities so that students can only
use it to learn and not use it to to cheat but

00:05:39.300 --> 00:05:43.680
uh before so as I said parents and teachers
can see everything that students are up to and

00:05:43.680 --> 00:05:47.820
if students try to do something that's a little
bit off might be harmful to themselves or others

00:05:48.480 --> 00:05:54.840
parents and teachers will be notified but just
to get a sense of the types of activities we can

00:05:54.840 --> 00:05:58.800
engage in you have this tutor me activity
which is actually very similar to what we

00:05:58.800 --> 00:06:03.000
did in that exercise but here you can get
tutored on pretty much any any subject you

00:06:03.000 --> 00:06:12.540
want in math or science or the humanities uh
we could say I want to understand entropy more

00:06:15.060 --> 00:06:19.380
ah entropy a fascinating Concept in B indeed to
better understand your current knowledge can you

00:06:19.380 --> 00:06:22.440
tell me what you already know about entropy or
what specific aspect you'd like to explore so we

00:06:22.440 --> 00:06:27.900
can continue to have a conversation and it acts
like a really good tutor uh this is a fun one

00:06:27.900 --> 00:06:31.920
called ignite your curiosity we could pick from
one of these subjects here or you can even put

00:06:31.920 --> 00:06:36.240
another approach as long as it's appropriate it
won't let you go to any inappropriate uh topics

00:06:36.240 --> 00:06:42.540
hopefully um but let's say you say I want
to explore I want to explore world history

00:06:44.940 --> 00:06:50.160
and this is a kind of a way of jumping into the
rabbit hole where it gives you some interesting

00:06:50.160 --> 00:06:54.840
questions but you can ask your own questions
at any time as well but says Ah world history a

00:06:54.840 --> 00:07:00.780
tapestry of tales woven together through time and
I love the Emojis let's dive into some tantalizing

00:07:00.780 --> 00:07:04.860
questions and so we can pick or we could ask
our own what was the real purpose behind the

00:07:04.860 --> 00:07:11.100
construction of the Great Wall of China how did
the Silk Road impact the world etc etc I I don't

00:07:11.100 --> 00:07:15.240
know I'm kind of curious about that first one the
real purpose of the construction of the Great Wall

00:07:15.240 --> 00:07:21.480
of China ah the Great Wall of China a magnificent
Marvel stretching over 13 000 miles the primary

00:07:21.480 --> 00:07:25.560
purpose of the Great Wall was to protect China
from Invasion by nomadic times particularly the

00:07:25.560 --> 00:07:30.240
Mongols it also helped as a symbol of power and
unity showcasing the strength of the Chinese

00:07:30.240 --> 00:07:37.680
Empire so we can keep asking more questions
I could also say why couldn't the Mongols

00:07:40.020 --> 00:07:47.220
just go over or around the
wall we put the wall in capital

00:07:50.400 --> 00:07:54.600
uh excellent question while the Great Wall
was an imposing structure it wasn't entirely

00:07:54.600 --> 00:07:59.100
impenetrable in fact the Mongols did manage to
breach the wall on several occasions however

00:07:59.100 --> 00:08:03.600
the wall still served a significant deterrent
and made envisions more and more difficult so

00:08:03.600 --> 00:08:09.660
this is just a fun way to really dive deep and
I gotta say again I love I love the Emojis now

00:08:09.660 --> 00:08:15.420
beyond that we have practice in pretty much any
subject that a student might want let's say we

00:08:15.420 --> 00:08:20.460
wanted to prepare for a trivia night but you could
really put almost anything here that's reasonable

00:08:21.060 --> 00:08:26.160
and so it asked you questions in which country
would you find the Great Pyramid of Giza of course

00:08:26.160 --> 00:08:31.260
of course going to be Egypt and so great
it matches what's the largest planet of

00:08:31.260 --> 00:08:34.800
solar system you could keep going but it
also maybe more importantly has many many

00:08:34.800 --> 00:08:38.160
different academic subjects in elementary
school middle school I could go through each

00:08:38.160 --> 00:08:46.200
of these both Humanities and stem subjects
middle school high school we have every AP

00:08:46.200 --> 00:08:52.260
course here for example I could click on
I don't know let's click on US government

00:08:54.300 --> 00:08:58.980
awesome Choice here are 10 top 10 subtopics
in AP US Government that you might want to

00:08:58.980 --> 00:09:03.240
be quizzed on so what do we want to do we
could do all of the above I don't know let's

00:09:03.240 --> 00:09:08.640
do foundations of American democracy and once
again it is doing quizzing it's going to quiz

00:09:08.640 --> 00:09:12.900
me as much as I want and help evaluate me but
I can also ask questions about whenever I want

00:09:13.680 --> 00:09:17.580
so the first question what are the key
principles of John Locke's political

00:09:17.580 --> 00:09:22.800
philosophy that influenced the founding fathers
when drafting the US Constitution don't worry if

00:09:22.800 --> 00:09:26.400
you're not sure I can always give hints or
explain things so let's say give me a hint

00:09:30.420 --> 00:09:33.240
so it's centered around the idea of
natural rights and social contract

00:09:33.240 --> 00:09:37.920
think about three fundamental rights you
believed all individuals had and how the

00:09:37.920 --> 00:09:45.240
government's role is to protect these rights
so let's say the right to the right to property

00:09:46.320 --> 00:09:51.840
and to be happy I'm intentionally
not giving it the perfect answer

00:09:54.960 --> 00:09:59.400
so it says so it gives its take you know you are
on the right track with the right to property and

00:09:59.400 --> 00:10:04.020
happiness the key principles are life liberty
and property which are similar to the phrase

00:10:04.020 --> 00:10:08.760
life liberty and the pursuit of happiness found
in the Declaration of Independence great effort

00:10:08.760 --> 00:10:15.960
and you could keep going what is the main purpose
of the Federalists to argue for a stronger Central

00:10:16.920 --> 00:10:17.640
government

00:10:20.400 --> 00:10:22.620
than what we're in the article
well I'll just write it that way

00:10:26.220 --> 00:10:30.660
you got it right the Federalist Papers were indeed
written to argue for a stronger central government

00:10:30.660 --> 00:10:34.920
so you can quiz yourself as much as you want
on any of these topics I think this will be

00:10:34.920 --> 00:10:40.620
particularly uh useful honestly for any student
who's looking to study across subjects stem and

00:10:40.620 --> 00:10:46.080
Humanities especially a lot of students preparing
for AP going well into college and Beyond and if

00:10:46.080 --> 00:10:49.500
you don't see something that you have here if
you're taking more specialized course you could

00:10:49.500 --> 00:10:54.600
just type it in over here we have these
activities where students can debate the

00:10:54.600 --> 00:10:59.640
AI or debate Khanmigo or vice versa these are
Elementary School topics like are zoos helpful

00:10:59.640 --> 00:11:04.140
or harmful to animals you have Middle School
topics like are cell phones helpful or harmful

00:11:04.140 --> 00:11:10.380
in classrooms high school and Beyond topics and
we've populated a bunch of them like should the

00:11:10.380 --> 00:11:13.500
student government cancel student debt well
artificial intelligence help or hurt the job

00:11:13.500 --> 00:11:18.720
market what you can do is you can take one side
of the issue so let's say let's debate whether

00:11:18.720 --> 00:11:23.040
the government should cancel student debt and
I'm just this is you know don't don't send me

00:11:23.040 --> 00:11:27.360
mail I'm just taking one point of view to
fine-tune the arguments on either side I

00:11:27.360 --> 00:11:34.860
will not tell you my actual opinion but let's
say I'm against I'm against canceling the debt

00:11:37.260 --> 00:11:40.620
all right you're against canceling student
debt please go ahead and present your argument

00:11:40.620 --> 00:11:47.760
and I'll be ready to counter and present my side
let the debate begin and so we can say canceling

00:11:49.920 --> 00:11:57.240
doesn't solve the underlying
issue of expensive College

00:11:58.920 --> 00:12:13.140
you cancel for one group and and the next
generation will still accumulate debt let's

00:12:13.140 --> 00:12:23.940
see what else could I say oh I could I could
say this is also an insult to those who worked

00:12:25.680 --> 00:12:42.660
hard to pay their debt and is a a dis incentive
for others to pay hoping it will be canceled

00:12:44.760 --> 00:12:51.960
the real solution is to make College cheaper

00:12:54.960 --> 00:12:59.520
and let's see what it responds ah well constructed
argument I see your point about canceling student

00:12:59.520 --> 00:13:03.540
debt not addressing the root cause of expensive
college education and I understand how it might

00:13:03.540 --> 00:13:07.200
seem unfair to those who have already paid off
their debts however allow me to present the other

00:13:07.200 --> 00:13:11.100
side of the coin canceling student debt even if
it doesn't solve the owner and you could see it

00:13:11.100 --> 00:13:14.700
keeps going on and on you can spend hours with
this thing and this is just one of the many many

00:13:14.700 --> 00:13:22.320
many things you can debate we can chat with
a historical figure for example let's talk to

00:13:23.220 --> 00:13:32.220
I don't know let's talk to [Music] um let
me talk to let me talk to George Washington

00:13:34.200 --> 00:13:37.620
uh it is an honor to be summoned as the first
president United States George Washington I am

00:13:37.620 --> 00:13:41.400
here to share my experiences and answer your
questions as long as they pertain to my time

00:13:41.400 --> 00:13:46.020
and context what inquiry do you have for me
my dear fellow and do tell me what interests

00:13:46.020 --> 00:13:56.820
you most about my life or the era in which I
lived have you ever been unsure of yourself

00:13:59.340 --> 00:14:03.360
indeed there were moments in my life when I
experienced uncertainty and doubt leading the

00:14:03.360 --> 00:14:07.140
Continental Army during the American Revolution
was a great responsibility and I often found

00:14:07.140 --> 00:14:12.000
myself questioning my decisions however I firmly
believed it was the cause for it was I firmly

00:14:12.000 --> 00:14:15.720
believed in the cause for which we fought and I
endeavored to learn from my mistakes and adopt

00:14:15.720 --> 00:14:20.160
my strategies accordingly so obviously we could go
on and ask all sorts of things and of course this

00:14:20.160 --> 00:14:27.720
is a simulation it's you know to treat it as it is
but there's a lot that we can we can be doing here

00:14:28.680 --> 00:14:34.560
literary characters uh there are some here I
could say well you know I like unless I would

00:14:34.560 --> 00:14:39.480
love to meet Zeus ah mortal I am Zeus
the king of the Gods and ruler of Mount

00:14:39.480 --> 00:14:45.660
Olympus I preside over the sky and thunder and
uphold Justice and law what does thou wish to

00:14:45.660 --> 00:14:53.640
know or discuss with me the Mighty Zeus and
what questions what are your insecurities

00:14:55.920 --> 00:15:01.800
I've always wanted to know this uh as Zeus the
supreme ruler of the Gods I am not one to dwell

00:15:01.800 --> 00:15:06.300
on insecurities however I faced many challenges
in maintaining my rule and ensuring the Loyalty

00:15:06.300 --> 00:15:10.260
of my fellow gods and goddesses there have been
times when my authority has been questioned and

00:15:10.260 --> 00:15:15.120
I've had to assert my power to maintain order
now mortal tell me about a challenge you have

00:15:15.120 --> 00:15:21.300
faced in your life and how you overcame it so
it's nicely driving the conversation but there

00:15:21.300 --> 00:15:27.660
is more this is essentially a college coach that
you could talk to about navigating financial aid

00:15:27.660 --> 00:15:35.340
how you can pick Majors etc etc also a lot of
fun this is a fun activity that helps combine

00:15:35.340 --> 00:15:41.400
reading comprehension and vocabulary and get
a little fact knowledge there so it says you

00:15:41.400 --> 00:15:44.400
know let me know what grade level you're
in I don't know let me say I'm sixth grader

00:15:45.480 --> 00:15:53.580
it's going to give me 10 vocabulary words it would
be useful for a sixth grader to know and then it's

00:15:53.580 --> 00:15:57.720
going to use them it's going to construct passages
and we I can pick what I want the story to be

00:15:57.720 --> 00:16:04.680
around so let's say let's make it about um the
Mysterious Island a journey through space and time

00:16:06.780 --> 00:16:10.980
all right so what it's doing now is it's
using those vocabulary words one paragraph

00:16:10.980 --> 00:16:17.220
at a time and I need to identify which of
those usages were was incorrect so once

00:16:17.220 --> 00:16:22.080
upon a time a group of apprehensive explorers
set sail on a daring adventure to find well

00:16:22.080 --> 00:16:27.600
apprehensive doesn't sound right that's not what
an Explorer would be so I'll write apprehensive

00:16:28.620 --> 00:16:37.500
is wrong should be something
like Brave or Intrepid

00:16:40.680 --> 00:16:41.340
whoops

00:16:44.460 --> 00:16:48.300
you got it apprehensive doesn't fit the context
and braver Intrepid would be a better choice

00:16:48.300 --> 00:16:52.560
great job and so and then it keeps building on
that story about the explorers and it's actually

00:16:52.560 --> 00:16:56.880
giving me some content knowledge while we're
doing it this craft a story it's essentially

00:16:56.880 --> 00:17:02.640
it helps develop characters and then it trades
off it's an activity that many of y'all might

00:17:02.640 --> 00:17:06.000
have seen maybe you've done it with kids or
you've done it with your parents where you

00:17:06.000 --> 00:17:09.300
write a paragraph then it writes a paragraph
then you write a paragraph then it writes a

00:17:09.300 --> 00:17:15.540
paragraph and you work with the bot to create
a story and we really you know this is really

00:17:15.540 --> 00:17:19.740
important to us that we're all about learning and
not about cheating so this isn't about hey just

00:17:19.740 --> 00:17:24.420
do the essay for me it's about let's do something
creative together now I promised that it wouldn't

00:17:24.420 --> 00:17:30.000
just be for students it's also for teachers they
can develop parts of a lesson like a lesson hook

00:17:30.000 --> 00:17:36.180
or exit tickets or entire lesson plans altogether
so ask me what grade I'm teaching let's say I'm

00:17:36.180 --> 00:17:44.880
teaching ninth grade I want to teach I'm going
to teach the causes of the Civil of the civil War

00:17:47.940 --> 00:17:51.600
oh the cause of the Civil War what a fascinating
thought-provoking topic for ninth graders anyway

00:17:51.600 --> 00:17:55.140
would you like me to create a rough draft of
the lesson plan or do you want to provide more

00:17:55.140 --> 00:17:59.400
information to customize it further so you can and
you could say whether you want to be Project based

00:17:59.400 --> 00:18:03.060
or Hands-On or whether you want to facilitate a
conversation they'll go into all of the details

00:18:03.060 --> 00:18:07.560
of what makes a great lesson plan but just for the
sake of this demo I'm just going to say give me a

00:18:07.560 --> 00:18:13.500
rough draft just see what it what it can produce
on this and what's interesting is it is producing

00:18:13.500 --> 00:18:17.400
a full complete lesson plan that I can take with
9th graders that would be appropriate for them

00:18:17.400 --> 00:18:25.260
and it it it produces it and I can then tweak it
if I want them to make it more exciting or make

00:18:25.260 --> 00:18:31.200
it more Hands-On or change the assessment um or
or I could I could answer more of its questions

00:18:31.200 --> 00:18:37.320
however however wants and you know it's just fun
to see like you know even like some of the hooks

00:18:37.320 --> 00:18:42.120
and things it creates begin with a quick pull do
you think the Civil War was a was inevitable why

00:18:42.120 --> 00:18:45.840
or why not and encourage students to share their
thoughts briefly and you could ask for a different

00:18:45.840 --> 00:18:51.660
type of hook and we even have a lesson hook um
actual activity here this refreshed my knowledge

00:18:51.660 --> 00:18:58.320
is forced a teacher uh if hey you know I teach the
Civil War every year but right before I teach it

00:18:58.320 --> 00:19:03.060
it's nice to be able to at least make sure that
I have I have a decent handle or I remember all

00:19:03.060 --> 00:19:12.300
of the details so let's say I had that lesson
ninth grade ninth grade causes of the Civil War

00:19:15.180 --> 00:19:19.620
so quizzing on the topic learning through
conversation let's say I'm quiz quiz me on the

00:19:19.620 --> 00:19:26.460
topic so here's like the major the major things
first concept economic and social difference

00:19:26.460 --> 00:19:29.460
between the North South can you explain the key
differences between the North and South that

00:19:29.460 --> 00:19:43.980
contributed to tensions North was more Industrial
and didn't have slavery South was agricultural

00:19:46.440 --> 00:19:53.760
and was dependent on slavery to some degree

00:19:56.640 --> 00:20:00.840
that's correct so this is a way I as a
teacher can just make sure that okay and

00:20:00.840 --> 00:20:05.520
this works not just in the humanities you
could it could be in the Sciences whatever

00:20:05.520 --> 00:20:09.660
you're about to teach you can get the lesson
plan get your hook refresh your knowledge

00:20:10.440 --> 00:20:14.160
um and then there's even a couple of fun things
here you can kind of just put stuff about your

00:20:14.160 --> 00:20:18.900
classroom here and it can kind of create a fun
poem for what everyone did together and as much

00:20:18.900 --> 00:20:23.160
as you already see here and I haven't even gone
through all of all of these activities and I

00:20:23.160 --> 00:20:26.400
obviously haven't shown you all the other stuff
on Khan Academy and the related links and how it

00:20:26.400 --> 00:20:31.020
can connect what you're doing here to the other
things on Khan Academy we hope to we're already

00:20:31.020 --> 00:20:37.020
testing this with teachers and co-designing it
with teachers and Educators working with students

00:20:37.860 --> 00:20:42.660
um and this is all right now going to be behind
con Labs we're creating a waiting list for any

00:20:42.660 --> 00:20:46.920
of y'all who want to be part of it we are going
to prioritize donors because we do need to fund

00:20:46.920 --> 00:20:51.780
the research and development of this but over
the coming months we hope to roll this out to

00:20:51.780 --> 00:20:57.060
more and more folks with a priority for schools
in the uh that are already part of the Khan

00:20:57.060 --> 00:21:02.220
Academy District offering and we also hope to
release more and more activities for teachers

00:21:02.220 --> 00:21:10.020
parents and students hopefully on even a weekly
basis um in the in the months to come so uh I

00:21:10.020 --> 00:21:16.080
look forward to for all of you all getting a
chance to uh to Play and Learn with Khanmigo

00:00:00.420 --> 00:00:01.440
- What'd you get on the math part?

00:00:01.440 --> 00:00:02.340
- 430.

00:00:02.340 --> 00:00:04.110
- What did you think you needed?

00:00:04.110 --> 00:00:04.943
- I don't know.

00:00:04.943 --> 00:00:06.600
My teacher told me 420.

00:00:06.600 --> 00:00:08.777
Really? Oh, my gosh, stop.

00:00:08.777 --> 00:00:09.870
(people chuckling)

00:00:09.870 --> 00:00:13.597
Really?
- Congrats. Yes, you did it.

00:00:13.597 --> 00:00:14.430
- I'm so sorry.

00:00:14.430 --> 00:00:15.263
- You did it.

00:00:15.263 --> 00:00:16.920
It's a big weight lifted
off your shoulders.

00:00:16.920 --> 00:00:18.150
It's been happening all day.

00:00:18.150 --> 00:00:20.223
- I'm graduating. (laughs)

00:00:20.223 --> 00:00:21.660
- The difference that
Khan Academy has made

00:00:21.660 --> 00:00:24.960
for my students is giving
them real adaptive results

00:00:24.960 --> 00:00:28.110
that change the trajectory
that that student is on,

00:00:28.110 --> 00:00:29.640
and they can actually see an outcome

00:00:29.640 --> 00:00:32.250
as far as a change in their SAT score.

00:00:32.250 --> 00:00:34.920
- We had students who, by using Kahn

00:00:34.920 --> 00:00:37.320
they were able to make their
graduation requirements.

00:00:37.320 --> 00:00:41.070
Seeing student success
really is what propelled us

00:00:41.070 --> 00:00:43.710
that this is the way we
needed to go in our district.

00:00:43.710 --> 00:00:46.410
- The benefit that Khan Academy
brings to our district here

00:00:46.410 --> 00:00:48.690
in Osceola County is that it allows

00:00:48.690 --> 00:00:52.110
all of our students to
have an equal opportunity

00:00:52.110 --> 00:00:54.240
to be ready for the SAT.

00:00:54.240 --> 00:00:57.900
We have proven results with
the use of Khan Academy.

00:00:57.900 --> 00:00:59.730
We know that when students score

00:00:59.730 --> 00:01:02.580
as high as they possibly can on the SAT

00:01:02.580 --> 00:01:04.110
that it opens doors for them.

00:01:04.110 --> 00:01:06.960
- My last score of SAT was 410

00:01:06.960 --> 00:01:08.760
and that was like one question

00:01:08.760 --> 00:01:11.370
but like behind from passing the test

00:01:11.370 --> 00:01:15.660
and now I got a 430 and
I am able to graduate.

00:01:15.660 --> 00:01:18.420
- So I took the SAT twice,
junior year and senior year.

00:01:18.420 --> 00:01:19.740
When I took it in junior year

00:01:19.740 --> 00:01:22.020
I hadn't used Khan Academy just yet

00:01:22.020 --> 00:01:24.000
and in senior year when I took it again

00:01:24.000 --> 00:01:25.860
I actually was using Khan
Academy over the summer.

00:01:25.860 --> 00:01:28.200
My points increased by about 120, 130.

00:01:28.200 --> 00:01:31.410
- The students who have done
really well with Khan Academy

00:01:31.410 --> 00:01:33.900
are our emergent bilingual students.

00:01:33.900 --> 00:01:36.330
When they're trying to
get this concordance score

00:01:36.330 --> 00:01:40.320
on the SAT or ACT, I see them jump so far.

00:01:40.320 --> 00:01:42.270
- Since English is not my first language

00:01:42.270 --> 00:01:44.730
it actually helped me how
to learn the language,

00:01:44.730 --> 00:01:46.800
how to read and write.

00:01:46.800 --> 00:01:48.570
For example, questions with semi colons,

00:01:48.570 --> 00:01:50.790
I know how to do them
because of Khan Academy.

00:01:50.790 --> 00:01:52.590
- So I think that was a lot of buy-in

00:01:52.590 --> 00:01:54.990
as far as from the student
side with using Khan Academy

00:01:54.990 --> 00:01:56.107
because they were seeing like,

00:01:56.107 --> 00:01:57.945
"Oh, it's right," or, "Oh, it works."

00:01:57.945 --> 00:02:01.332
(Mia speaking Spanish)

00:02:01.332 --> 00:02:03.238
(Ma speaking Spanish)

00:02:03.238 --> 00:02:05.555
(Mia speaking Spanish)

00:02:05.555 --> 00:02:06.480
(Ma speaking Spanish)

00:02:06.480 --> 00:02:07.944
- Yeah.

00:02:07.944 --> 00:02:10.740
(Ma speaking Spanish)

00:02:10.740 --> 00:02:13.800
- Khan Academy is a guaranteed way

00:02:13.800 --> 00:02:16.650
to increase student
achievement as relates to SAT.

00:02:16.650 --> 00:02:19.740
- Everything I practiced
on Kahn was on the test.

00:02:19.740 --> 00:02:21.360
Thank you Khan Academy, you guys,

00:02:21.360 --> 00:02:24.570
for providing the tools
that I needed to pass.

00:02:24.570 --> 00:02:26.130
I really appreciate it.

00:02:26.130 --> 00:02:27.679
I'm super, super happy.

00:00:00.206 --> 00:00:02.873
(upbeat music)

00:00:04.140 --> 00:00:05.880
- The benefit that Khan Academy brings

00:00:05.880 --> 00:00:07.350
to our school district,

00:00:07.350 --> 00:00:09.690
is being able to provide a platform

00:00:09.690 --> 00:00:14.220
that provides individualized,
practice, study skill,

00:00:14.220 --> 00:00:15.930
and the ability for students

00:00:15.930 --> 00:00:18.570
to increase their knowledge proficiency.

00:00:18.570 --> 00:00:22.290
- The support that Khan Academy
provides us is one-on-one

00:00:22.290 --> 00:00:23.940
and tailored to our district.

00:00:23.940 --> 00:00:27.390
They're extremely
understanding of our scenario

00:00:27.390 --> 00:00:30.510
and what we are looking
to gain from the platform.

00:00:30.510 --> 00:00:32.340
- [Sal] With the Khan Academy
Districts partnership,

00:00:32.340 --> 00:00:35.340
we take our highly efficacious
and trusted content.

00:00:35.340 --> 00:00:38.280
- The content in Khan
Academy lines up so well

00:00:38.280 --> 00:00:39.630
with our course curriculum

00:00:39.630 --> 00:00:41.220
when we dig for specific subjects.

00:00:41.220 --> 00:00:42.810
It's something that is wanted

00:00:42.810 --> 00:00:45.120
that a lot of teachers already believe in.

00:00:45.120 --> 00:00:46.200
- We've seen the data,

00:00:46.200 --> 00:00:49.020
we've seen that it
works with our students.

00:00:49.020 --> 00:00:51.540
Our growth in our SAT has been proven.

00:00:51.540 --> 00:00:53.400
- [Sal] And we supercharge your classroom

00:00:53.400 --> 00:00:55.860
with student to admin level reporting

00:00:55.860 --> 00:00:57.720
to give you data-driven insight

00:00:57.720 --> 00:00:59.190
into the needs of your students.

00:00:59.190 --> 00:01:01.980
- I really do like how
the data was very easy.

00:01:01.980 --> 00:01:03.750
The reports are very easy,

00:01:03.750 --> 00:01:05.310
and it was easy for our teachers

00:01:05.310 --> 00:01:06.810
to be able to read those

00:01:06.810 --> 00:01:08.850
and to be able to guide
their lessons as well.

00:01:08.850 --> 00:01:10.110
- Everything's a one-stop shop,

00:01:10.110 --> 00:01:11.940
so that helps a lot to
speed up the process

00:01:11.940 --> 00:01:13.080
and to get them on the platform,

00:01:13.080 --> 00:01:14.310
which is where we want them to be

00:01:14.310 --> 00:01:15.540
for the learning to take place.

00:01:15.540 --> 00:01:17.880
- [Sal] Whether your
district is large or small,

00:01:17.880 --> 00:01:19.800
our expert team of educators

00:01:19.800 --> 00:01:21.900
are here to support your entire district.

00:01:21.900 --> 00:01:23.460
You'll get a support team committed

00:01:23.460 --> 00:01:26.370
to empowering district
leaders, site leaders,

00:01:26.370 --> 00:01:28.320
coaches, and teachers,

00:01:28.320 --> 00:01:31.320
so each student can
master grade level skills,

00:01:31.320 --> 00:01:33.390
and address their unique learning gaps.

00:01:33.390 --> 00:01:35.400
- Khan Academy really listens to you

00:01:35.400 --> 00:01:38.130
to find out what are your
professional development needs,

00:01:38.130 --> 00:01:40.547
and how can we best tailor
our professional development

00:01:40.547 --> 00:01:42.300
to the needs of your district.

00:01:42.300 --> 00:01:44.160
- Guidance along the way,

00:01:44.160 --> 00:01:46.830
we never felt that we were
in this process alone.

00:01:46.830 --> 00:01:48.150
- It takes a lot off of me,

00:01:48.150 --> 00:01:51.360
and now we can go in, start the lessons.

00:01:51.360 --> 00:01:53.790
The teachers can go in and
start looking at those skills

00:01:53.790 --> 00:01:56.070
that they need to
prepare their lessons for

00:01:56.070 --> 00:01:57.330
through Khan Academy,

00:01:57.330 --> 00:01:59.700
and then we're using it as
part of our intervention.

00:01:59.700 --> 00:02:01.710
- If you use Khan Academy,

00:02:01.710 --> 00:02:04.080
you will see success

00:02:04.080 --> 00:02:06.480
and that is not an anomaly for us.

00:02:06.480 --> 00:02:09.120
We saw it time and time again.

00:02:09.120 --> 00:02:12.270
- I'm Sal Khan and I founded
Khan Academy many years ago

00:02:12.270 --> 00:02:14.310
as a not-for-profit organization,

00:02:14.310 --> 00:02:16.110
because I always wanted to ensure

00:02:16.110 --> 00:02:18.780
that we put impact for your learners

00:02:18.780 --> 00:02:21.000
above any notion of profit.

00:02:21.000 --> 00:02:23.700
Khan Academy is the most used platform

00:02:23.700 --> 00:02:25.410
in the country, and actually the world,

00:02:25.410 --> 00:02:27.480
to address unfinished learning.

00:02:27.480 --> 00:02:29.160
We're going to work with you

00:02:29.160 --> 00:02:32.580
to accelerate your learners at grade level

00:02:32.580 --> 00:02:34.500
and give you and your teachers

00:02:34.500 --> 00:02:37.710
the data that they need
to support that learning.

00:02:37.710 --> 00:02:38.760
To learn more about

00:02:38.760 --> 00:02:40.890
how a Khan Academy Districts partnership

00:02:40.890 --> 00:02:42.090
can provide your district

00:02:42.090 --> 00:02:43.860
with the personalized support you need,

00:02:43.860 --> 00:02:46.348

US Government and Civics Introduction

Language: en

00:00:00.960 --> 00:00:02.550
- Hi, everyone, Sal Khan here.

00:00:02.550 --> 00:00:04.740
And I just wanted to invite you,

00:00:04.740 --> 00:00:06.510
or tell you a little bit about

00:00:06.510 --> 00:00:09.180
our course on US Government and Civics.

00:00:09.180 --> 00:00:10.740
The first question you
might be wondering is

00:00:10.740 --> 00:00:14.190
why do I need to learn
about government and civics?

00:00:14.190 --> 00:00:15.540
And what I would tell you is

00:00:15.540 --> 00:00:18.210
because you are a member of our democracy.

00:00:18.210 --> 00:00:20.430
A democracy does not work

00:00:20.430 --> 00:00:23.520
unless the people who
make up the democracy

00:00:23.520 --> 00:00:24.990
are willing to be informed,

00:00:24.990 --> 00:00:27.720
willing to understand
what rights they have,

00:00:27.720 --> 00:00:29.820
and potentially what rights they give up

00:00:29.820 --> 00:00:33.690
in order to have a
better-functioning society.

00:00:33.690 --> 00:00:35.970
So if we wanna function as a society,

00:00:35.970 --> 00:00:37.980
you should pay attention to this course.

00:00:37.980 --> 00:00:39.840
And just so you know what this covers,

00:00:39.840 --> 00:00:43.020
we start with the foundations
of American democracy.

00:00:43.020 --> 00:00:44.190
How did we get to where we are?

00:00:44.190 --> 00:00:45.660
You might not appreciate it.

00:00:45.660 --> 00:00:46.493
You might say, "Oh,

00:00:46.493 --> 00:00:48.960
democracy goes all the way
back to the ancient Greeks."

00:00:48.960 --> 00:00:51.060
But the reality is,

00:00:51.060 --> 00:00:52.860
the modern form of democracy

00:00:52.860 --> 00:00:55.530
really started with American democracy

00:00:55.530 --> 00:00:57.330
and then it has been replicated
throughout the world.

00:00:57.330 --> 00:01:00.510
So understand the tensions
that the founders faced

00:01:00.510 --> 00:01:03.090
and how they got to a pretty nice balance

00:01:03.090 --> 00:01:06.120
that's at least worked
for several hundred years.

00:01:06.120 --> 00:01:08.460
Then we're gonna talk about interactions

00:01:08.460 --> 00:01:10.470
amongst the branches of government.

00:01:10.470 --> 00:01:12.390
Some of y'all have heard
about checks and balances,

00:01:12.390 --> 00:01:14.730
the executive branch, the judicial branch,

00:01:14.730 --> 00:01:15.933
the legislative branch.

00:01:17.100 --> 00:01:19.530
How does all of that work together?

00:01:19.530 --> 00:01:22.290
Then, civil liberties and civil rights.

00:01:22.290 --> 00:01:23.460
What are your rights?

00:01:23.460 --> 00:01:24.780
What are other people's rights?

00:01:24.780 --> 00:01:26.610
How do we make sure that they are

00:01:26.610 --> 00:01:28.650
guarded by things like the Bill of Rights?

00:01:28.650 --> 00:01:31.580
And also more modern versions

00:01:31.580 --> 00:01:35.610
of what civil liberties and
civil rights actually mean.

00:01:35.610 --> 00:01:38.250
Then, we talk about citizenship.

00:01:38.250 --> 00:01:39.870
You might just think about citizenship

00:01:39.870 --> 00:01:42.780
as a bunch of privileges
you get as a citizen,

00:01:42.780 --> 00:01:44.280
but there's also some obligations.

00:01:44.280 --> 00:01:46.140
So think about that a little bit.

00:01:46.140 --> 00:01:47.520
And then we're gonna talk about

00:01:47.520 --> 00:01:50.220
ideologies and beliefs, politics,

00:01:50.220 --> 00:01:52.170
things like political parties,

00:01:52.170 --> 00:01:53.340
which you're probably familiar with,

00:01:53.340 --> 00:01:55.320
maybe even tired of hearing about.

00:01:55.320 --> 00:01:58.320
But it never hurts to be
armed with more information.

00:01:58.320 --> 00:02:02.040
And then, how do you
become a better participant

00:02:02.040 --> 00:02:03.150
in our democracy?

00:02:03.150 --> 00:02:05.400
The topic of political participation.

00:02:05.400 --> 00:02:08.280
And then we have a bunch of
other topics that you'll see

00:02:08.280 --> 00:02:11.760
that connect to even
more modern world topics,

00:02:11.760 --> 00:02:14.310
things that are relevant
in your everyday life.

00:02:14.310 --> 00:02:17.640
So take a journey with us
in US Government and Civics

00:02:17.640 --> 00:02:20.130
and I...One, you'll learn
a lot about the world.

00:02:20.130 --> 00:02:22.380
You'll be even more
popular at dinner parties.

00:02:22.380 --> 00:02:24.000
But even most importantly,

00:02:24.000 --> 00:02:26.820
you will know how to participate

00:02:26.820 --> 00:02:30.903
in our democracy and make
us a more perfect union.


Earth's fossil record

WEBVTT
Kind: captions
Language: en

00:00:00.570 --> 00:00:02.040
- [Instructor] Life on Earth has existed

00:00:02.040 --> 00:00:03.870
for billions of years.

00:00:03.870 --> 00:00:05.580
Humans know this, not because we've been

00:00:05.580 --> 00:00:07.680
around the whole time, but instead,

00:00:07.680 --> 00:00:09.900
thanks to the discovery of fossils,

00:00:09.900 --> 00:00:11.670
which tell us about organisms

00:00:11.670 --> 00:00:13.560
that lived in the distant past.

00:00:13.560 --> 00:00:16.500
Scientists have found millions of fossils.

00:00:16.500 --> 00:00:18.270
Some, such as skeletons,

00:00:18.270 --> 00:00:21.840
document ancient organisms'
anatomy or physical features,

00:00:21.840 --> 00:00:24.390
while others, such as
preserved footprints,

00:00:24.390 --> 00:00:26.760
record organisms' behaviors.

00:00:26.760 --> 00:00:28.380
Each fossil that has been found

00:00:28.380 --> 00:00:30.810
is like a piece of a giant puzzle.

00:00:30.810 --> 00:00:33.900
To see the bigger picture of
the history of life on Earth,

00:00:33.900 --> 00:00:36.150
scientists have to study the many fossils

00:00:36.150 --> 00:00:39.450
and see how they all fit
together in the larger puzzle.

00:00:39.450 --> 00:00:42.030
All of the fossil puzzle pieces
that have been discovered,

00:00:42.030 --> 00:00:43.770
along with their relative ages,

00:00:43.770 --> 00:00:45.960
make up Earth's fossil record.

00:00:45.960 --> 00:00:49.230
The fossil record is basically
a history of life on Earth

00:00:49.230 --> 00:00:51.600
as documented through fossils.

00:00:51.600 --> 00:00:53.310
By studying the fossil record,

00:00:53.310 --> 00:00:55.080
scientists can see how life on Earth

00:00:55.080 --> 00:00:57.213
has changed over evolutionary time.

00:00:58.440 --> 00:01:00.870
The fossil record allows
us to see patterns

00:01:00.870 --> 00:01:02.760
of evolutionary changes that have happened

00:01:02.760 --> 00:01:04.110
throughout Earth's history.

00:01:04.110 --> 00:01:05.940
These include an overall increase

00:01:05.940 --> 00:01:08.640
in organism complexity and diversity

00:01:08.640 --> 00:01:10.080
and the changes that have occurred

00:01:10.080 --> 00:01:12.120
along evolutionary lineages,

00:01:12.120 --> 00:01:14.310
showing us how one group of organisms

00:01:14.310 --> 00:01:16.470
could have evolved to the next.

00:01:16.470 --> 00:01:18.150
The fossil record also shows us

00:01:18.150 --> 00:01:21.450
when certain groups of
organisms went extinct.

00:01:21.450 --> 00:01:23.310
First, let's take a look at the increase

00:01:23.310 --> 00:01:25.440
in organism complexity and diversity

00:01:25.440 --> 00:01:27.570
that is seen in fossil record.

00:01:27.570 --> 00:01:30.510
Over evolutionary time,
organisms have generally

00:01:30.510 --> 00:01:32.370
become more complicated.

00:01:32.370 --> 00:01:34.020
Some of the oldest known fossils

00:01:34.020 --> 00:01:38.760
are formations made by ancient
colonies of cyanobacteria.

00:01:38.760 --> 00:01:40.380
These fossils provide evidence

00:01:40.380 --> 00:01:43.110
that single-celled organisms
were living on Earth

00:01:43.110 --> 00:01:46.620
roughly around 3.5 billion years ago

00:01:46.620 --> 00:01:49.380
and that these organisms
were relatively simple,

00:01:49.380 --> 00:01:51.870
similar to the bacteria we have today.

00:01:51.870 --> 00:01:54.840
The fossil record then goes
on to document major leaps

00:01:54.840 --> 00:01:58.770
in complexity of life on
Earth, with, for example,

00:01:58.770 --> 00:02:02.160
the large tube-shape
cells of Grypania spiralis

00:02:02.160 --> 00:02:06.300
and the macroscopic organisms
in the Francevillian biota.

00:02:06.300 --> 00:02:08.460
According to scientists, these fossils,

00:02:08.460 --> 00:02:11.850
which are dated to be roughly
from 2 billion years ago,

00:02:11.850 --> 00:02:15.300
could provide evidence of some
of the earliest eukaryotic,

00:02:15.300 --> 00:02:17.400
or nucleus-containing cells,

00:02:17.400 --> 00:02:20.733
and of the earliest
multicellular organisms.

00:02:21.570 --> 00:02:23.460
Not only does the fossil record show

00:02:23.460 --> 00:02:26.490
an increase in complexity
over evolutionary time,

00:02:26.490 --> 00:02:30.090
but also an increase in the
diversity of life on Earth.

00:02:30.090 --> 00:02:32.580
For example, the Cambrian Explosion

00:02:32.580 --> 00:02:35.790
describes a multimillion
year span of time,

00:02:35.790 --> 00:02:39.990
beginning about 539 million years ago,

00:02:39.990 --> 00:02:41.730
in which there was a huge increase

00:02:41.730 --> 00:02:44.370
in the diversity of animals on Earth.

00:02:44.370 --> 00:02:47.340
Almost all of the animal
lineages we know today

00:02:47.340 --> 00:02:50.250
actually got started during this period.

00:02:50.250 --> 00:02:53.370
All of these increases in
complexity and diversity

00:02:53.370 --> 00:02:56.400
have given rise to the
millions of varied organisms

00:02:56.400 --> 00:02:58.500
that live on Earth today.

00:02:58.500 --> 00:03:00.480
Next, let's take a look at the changes

00:03:00.480 --> 00:03:03.360
that can be seen along
the evolutionary lineages

00:03:03.360 --> 00:03:05.100
in the Earth's fossil record.

00:03:05.100 --> 00:03:06.750
But before we do that,

00:03:06.750 --> 00:03:09.693
let's quickly look back at
how scientists study fossils.

00:03:10.530 --> 00:03:14.220
As you may recall, fossils are
found in sedimentary rocks,

00:03:14.220 --> 00:03:16.050
meaning that the deeper the fossil,

00:03:16.050 --> 00:03:18.540
the older the fossil is likely to be.

00:03:18.540 --> 00:03:21.870
So based on the layers in
which the fossil is found,

00:03:21.870 --> 00:03:24.150
scientists can put them in order by age.

00:03:24.150 --> 00:03:26.820
And in doing this,
scientists can piece together

00:03:26.820 --> 00:03:30.510
the evolutionary steps of
how one type of organism

00:03:30.510 --> 00:03:32.730
could have evolved into the next,

00:03:32.730 --> 00:03:35.370
eventually giving rise
to the living organisms

00:03:35.370 --> 00:03:37.320
we see today.

00:03:37.320 --> 00:03:38.940
To give an example of this,

00:03:38.940 --> 00:03:41.940
did you know that birds are
actually direct descendants

00:03:41.940 --> 00:03:44.640
of a group of dinosaurs called theropods?

00:03:44.640 --> 00:03:45.870
It may be hard to believe,

00:03:45.870 --> 00:03:47.460
but the fossil record shows

00:03:47.460 --> 00:03:50.100
that an organism known as Archaeopteryx

00:03:50.100 --> 00:03:53.790
existed about 150 million years ago,

00:03:53.790 --> 00:03:55.410
towards the end of the Dinosaur Age,

00:03:55.410 --> 00:03:58.140
but before the appearance of modern birds.

00:03:58.140 --> 00:04:00.810
This organism in
particular is interesting,

00:04:00.810 --> 00:04:04.080
because it had some features
unique to theropod dinosaurs,

00:04:04.080 --> 00:04:06.600
such as jaws and sharp teeth

00:04:06.600 --> 00:04:10.110
and some features unique
to birds, such as feathers.

00:04:10.110 --> 00:04:13.620
So Archaeopteryx represents
an evolutionary transition

00:04:13.620 --> 00:04:16.953
between theropod dinosaurs and
birds in the fossil record.

00:04:18.090 --> 00:04:21.030
Finally, let's take a look
at the patterns of extinction

00:04:21.030 --> 00:04:22.380
seen in the fossil record

00:04:22.380 --> 00:04:26.520
with the help of our extinct
friend, the Triceratops.

00:04:26.520 --> 00:04:30.390
Extinction happens when a
species completely dies out.

00:04:30.390 --> 00:04:32.850
In the fossil record, extinctions show up

00:04:32.850 --> 00:04:35.160
as organisms of a certain species

00:04:35.160 --> 00:04:37.470
being present in older rock layers

00:04:37.470 --> 00:04:41.220
and then completely disappearing
from the newer rock layers.

00:04:41.220 --> 00:04:44.160
For example, we only
see Triceratops fossils

00:04:44.160 --> 00:04:49.160
in rock layers that are roughly
68 to 66 million years old.

00:04:49.380 --> 00:04:51.300
After this, we don't find any evidence

00:04:51.300 --> 00:04:53.340
of Triceratops fossils anywhere

00:04:53.340 --> 00:04:56.820
and there certainly aren't
any Triceratops living today.

00:04:56.820 --> 00:04:59.970
The Triceratops is an important
example of extinction,

00:04:59.970 --> 00:05:01.860
as they not only went extinct,

00:05:01.860 --> 00:05:05.640
but they went extinct due
to a mass extinction event.

00:05:05.640 --> 00:05:07.350
Mass extinction events happened

00:05:07.350 --> 00:05:09.810
when large-scale environmental change

00:05:09.810 --> 00:05:12.420
caused many groups of
organisms to go extinct

00:05:12.420 --> 00:05:13.770
around the same time.

00:05:13.770 --> 00:05:15.810
When we see the triceratops disappear

00:05:15.810 --> 00:05:16.950
from the fossil record,

00:05:16.950 --> 00:05:20.550
we also see other types of
organisms disappear, too,

00:05:20.550 --> 00:05:23.220
providing evidence for
the mass extinction event

00:05:23.220 --> 00:05:27.390
that led to the disappearance
of all non-avian dinosaurs.

00:05:27.390 --> 00:05:30.420
And with that, you now know
what Earth's fossil record is

00:05:30.420 --> 00:05:33.240
and the various patterns it can show us.

00:05:33.240 --> 00:05:35.580
Earth's fossil record is an essential tool

00:05:35.580 --> 00:05:37.590
that scientists use to piece together

00:05:37.590 --> 00:05:39.570
the history of life on Earth.

00:05:39.570 --> 00:05:42.870
And new fossils are
continuously being discovered,

00:05:42.870 --> 00:05:44.760
so the fossil record is more

00:05:44.760 --> 00:05:46.980
than just a collection of fossils.

00:05:46.980 --> 00:05:49.680
It's a window into the
mysteries of the past

00:05:49.680 --> 00:05:52.260
and it's ever-growing
record of how life on Earth

00:05:52.260 --> 00:05:53.733
came to be what it is today.


Khan Stories: Mr. Brown

00:00:00.090 --> 00:00:01.980
- One summer I realized, you know what,

00:00:01.980 --> 00:00:05.190
I think Khan Academy actually
has all of this for me.

00:00:05.190 --> 00:00:06.660
So I spent the summer looking at it

00:00:06.660 --> 00:00:09.150
and I had two algebra classes,

00:00:09.150 --> 00:00:13.170
and I used one for like
completely Kahn Academy.

00:00:13.170 --> 00:00:16.470
I want you guys to watch the
videos, do all the quizzes,

00:00:16.470 --> 00:00:19.650
homework, tests, and
we're gonna see how it is.

00:00:19.650 --> 00:00:21.690
And the other class I
taught from the front

00:00:21.690 --> 00:00:24.330
and did my traditional
lesson plans like that.

00:00:24.330 --> 00:00:26.850
And it was pretty evident by Christmas

00:00:26.850 --> 00:00:30.120
that the kids that were able to, you know,

00:00:30.120 --> 00:00:33.390
that I was able to move around
and not teach from the front.

00:00:33.390 --> 00:00:35.010
Those kids were advancing more.

00:00:35.010 --> 00:00:36.840
Once I get going, it's
like I'm helping this kid,

00:00:36.840 --> 00:00:39.270
and I'm helping this kid, and
you know, kids are waiting,

00:00:39.270 --> 00:00:40.103
and so then all of a sudden

00:00:40.103 --> 00:00:41.040
they're starting to help each other,

00:00:41.040 --> 00:00:43.740
and it's just like this Socratic method,

00:00:43.740 --> 00:00:46.500
that is just, it's amazing to watch.

00:00:46.500 --> 00:00:48.510
And I get goosebumps every
time I think about it.

00:00:48.510 --> 00:00:51.060
And I realize that as a tiny school,

00:00:51.060 --> 00:00:53.070
and being the only math teacher,

00:00:53.070 --> 00:00:55.050
it gives me that flexibility.

00:00:55.050 --> 00:00:57.510
But I think, you know, with
just a little bit of creativity,

00:00:57.510 --> 00:00:59.430
I think bigger schools
could do the same thing,

00:00:59.430 --> 00:01:02.610
because it's still all in
their Khan Academy account.

00:01:02.610 --> 00:01:04.530
It's documented that they've learned it,

00:01:04.530 --> 00:01:05.640
that they've mastered it.

00:01:05.640 --> 00:01:08.520
Kids that just spent 20 minutes a day,

00:01:08.520 --> 00:01:10.503
averaged an 80% or above,

00:01:11.550 --> 00:01:13.533
80%, it was unbelievable.


Internet Safety Course Introduction

00:00:01.530 --> 00:00:02.363
- Hi everyone.

00:00:02.363 --> 00:00:03.720
Sal Khan here from Khan Academy,

00:00:03.720 --> 00:00:04.950
and I just wanted to welcome you

00:00:04.950 --> 00:00:07.800
to this course on internet safety.

00:00:07.800 --> 00:00:08.647
Now, you might be saying,

00:00:08.647 --> 00:00:10.200
"Why should I look at this course?

00:00:10.200 --> 00:00:12.540
The internet seems like
this fun and fabulous place

00:00:12.540 --> 00:00:13.830
where I can interact with folks

00:00:13.830 --> 00:00:16.500
and get information and do
all of these great things,"

00:00:16.500 --> 00:00:18.000
but you also need to realize

00:00:18.000 --> 00:00:21.240
that the internet can
be a dangerous place.

00:00:21.240 --> 00:00:23.580
There are people who are
going to want to get access

00:00:23.580 --> 00:00:26.700
to your personally
identifiable information,

00:00:26.700 --> 00:00:28.800
the things that would allow folks to say,

00:00:28.800 --> 00:00:31.560
take a credit card in your
name, or pretend to be you,

00:00:31.560 --> 00:00:33.330
or steal money from you.

00:00:33.330 --> 00:00:35.310
So you wanna figure out,
how do you protect that?

00:00:35.310 --> 00:00:38.940
And we'll have a lot more
content on what exactly PII,

00:00:38.940 --> 00:00:42.030
or personally identifiable information is.

00:00:42.030 --> 00:00:44.880
As you know on the internet,
you have many accounts.

00:00:44.880 --> 00:00:46.710
It could be an account for a site

00:00:46.710 --> 00:00:48.060
that allows you to play video games,

00:00:48.060 --> 00:00:49.530
but it could be your banking account.

00:00:49.530 --> 00:00:52.740
It could be where you send
emails from, your social media.

00:00:52.740 --> 00:00:54.500
There are folks out there that would love

00:00:54.500 --> 00:00:57.300
to have access to those accounts.

00:00:57.300 --> 00:00:59.850
They might be able to directly
do things on those accounts.

00:00:59.850 --> 00:01:01.410
It could be as little as embarrass you

00:01:01.410 --> 00:01:03.630
by taking advantage of
your social media account,

00:01:03.630 --> 00:01:05.250
or it could be stealing money from you

00:01:05.250 --> 00:01:07.380
if it's your bank account, or if you have

00:01:07.380 --> 00:01:09.990
the same password in
multiple places, well,

00:01:09.990 --> 00:01:13.470
they might be able to use that
from one place to another.

00:01:13.470 --> 00:01:16.260
So beware of everything on the internet.

00:01:16.260 --> 00:01:18.540
You have a lot of
information about yourself

00:01:18.540 --> 00:01:20.370
that could be valuable to others.

00:01:20.370 --> 00:01:22.320
And you're also going learn
that some of those folks

00:01:22.320 --> 00:01:23.310
are going try to trick you.

00:01:23.310 --> 00:01:25.410
You're gonna learn about
things like phishing attacks,

00:01:25.410 --> 00:01:28.050
where they're gonna try to
pretend to be someone else

00:01:28.050 --> 00:01:30.180
and make you feel really
urgent about doing something

00:01:30.180 --> 00:01:31.473
and giving information, once again,

00:01:31.473 --> 00:01:33.960
that you do not want these folks to have.

00:01:33.960 --> 00:01:35.670
So take a look at this course.

00:01:35.670 --> 00:01:37.320
It's going to be very,
very important to you.

00:01:37.320 --> 00:01:39.660
Hopefully none of this
stuff ever happens to you

00:01:39.660 --> 00:01:41.670
but if it does, you'll
know what to do about it,

00:01:41.670 --> 00:01:42.990
but even more importantly,

00:01:42.990 --> 00:01:44.790
you're going to know how to prevent it.

00:01:44.790 --> 00:01:46.773
So hopefully you enjoy this course.


Sexual reproduction and genetic variation

WEBVTT
Kind: captions
Language: en

00:00:00.330 --> 00:00:01.350
- [Narrator] Have you ever wondered

00:00:01.350 --> 00:00:03.750
why children often look a little similar

00:00:03.750 --> 00:00:07.110
but also very different from
their biological parents,

00:00:07.110 --> 00:00:08.940
or even how biological siblings

00:00:08.940 --> 00:00:10.680
tend to share some common features

00:00:10.680 --> 00:00:13.410
but still have different
traits from each other?

00:00:13.410 --> 00:00:14.820
To answer this question,

00:00:14.820 --> 00:00:16.680
we have to go beyond the physical traits

00:00:16.680 --> 00:00:18.360
that we see in these family portraits

00:00:18.360 --> 00:00:21.720
and dive into genetic inheritance.

00:00:21.720 --> 00:00:22.553
In this video,

00:00:22.553 --> 00:00:25.230
we're going to see that
it's sexual reproduction,

00:00:25.230 --> 00:00:28.830
a mechanism used by many
organisms to produce offspring,

00:00:28.830 --> 00:00:30.810
that creates the diversity of traits

00:00:30.810 --> 00:00:33.120
that exist in biological families

00:00:33.120 --> 00:00:36.690
and in animal and plant
populations all around the world.

00:00:36.690 --> 00:00:38.520
Let's start from the beginning.

00:00:38.520 --> 00:00:40.050
All life comes from other life

00:00:40.050 --> 00:00:42.450
through the process of reproduction.

00:00:42.450 --> 00:00:44.670
Parents reproduce to form offspring,

00:00:44.670 --> 00:00:45.780
and during this process,

00:00:45.780 --> 00:00:49.110
they pass on their genetic
information to their offspring.

00:00:49.110 --> 00:00:52.740
During sexual reproduction,
two parents produce offspring.

00:00:52.740 --> 00:00:56.100
So each offspring gets a
mixture of genetic information

00:00:56.100 --> 00:00:57.840
from two parents.

00:00:57.840 --> 00:01:00.510
Parents pass this genetic
information to their offspring

00:01:00.510 --> 00:01:03.540
via chromosomes, the
coiled up DNA molecules

00:01:03.540 --> 00:01:06.600
found inside your cells
that contain genes.

00:01:06.600 --> 00:01:08.400
Sexually reproducing organisms

00:01:08.400 --> 00:01:10.230
often have many different chromosomes,

00:01:10.230 --> 00:01:12.510
each containing specific genes.

00:01:12.510 --> 00:01:14.430
For example, this diagram represents

00:01:14.430 --> 00:01:16.980
a complete set of human chromosomes.

00:01:16.980 --> 00:01:19.830
As we can see, there are
23 different chromosomes

00:01:19.830 --> 00:01:22.410
assigned numbers one through 23.

00:01:22.410 --> 00:01:25.500
However, there are two
copies of each chromosome,

00:01:25.500 --> 00:01:27.720
so that there are 23 chromosome pairs

00:01:27.720 --> 00:01:30.780
instead of 23 single chromosomes.

00:01:30.780 --> 00:01:33.300
Each chromosome pair is a homologous pair,

00:01:33.300 --> 00:01:36.600
which means that the two
chromosomes are the same size

00:01:36.600 --> 00:01:39.990
and contain the same
genes in the same order.

00:01:39.990 --> 00:01:42.810
However, the alleles on the
two homologous chromosomes

00:01:42.810 --> 00:01:44.040
may be different,

00:01:44.040 --> 00:01:45.240
meaning that the chromosomes

00:01:45.240 --> 00:01:48.750
may not exactly have the
same genetic information.

00:01:48.750 --> 00:01:49.980
Also, in case you're wondering,

00:01:49.980 --> 00:01:52.140
the last chromosome set
is a little different,

00:01:52.140 --> 00:01:55.980
because that chromosome 23
is the human sex chromosome,

00:01:55.980 --> 00:01:59.310
which influences the biological
sex of the individual,

00:01:59.310 --> 00:02:01.860
but we don't have to
get into that just yet.

00:02:01.860 --> 00:02:03.708
What's important to know for our purposes

00:02:03.708 --> 00:02:06.360
is that sexually reproducing organisms

00:02:06.360 --> 00:02:08.880
with two sets of chromosomes
in each of their cells

00:02:08.880 --> 00:02:10.920
are called diploid.

00:02:10.920 --> 00:02:15.420
Diploid organisms, the
D-I, di indicating two,

00:02:15.420 --> 00:02:17.880
have cells with two sets of chromosomes

00:02:17.880 --> 00:02:21.120
that are organized into homologous pairs.

00:02:21.120 --> 00:02:22.800
Sexual reproduction occurs

00:02:22.800 --> 00:02:25.440
through a process called fertilization,

00:02:25.440 --> 00:02:27.000
and during fertilization,

00:02:27.000 --> 00:02:29.580
cells called gametes, which
are egg and sperm cells,

00:02:29.580 --> 00:02:32.100
fuse to form a new organism.

00:02:32.100 --> 00:02:34.380
Each parent contributes one gamete.

00:02:34.380 --> 00:02:35.820
So you might be wondering,

00:02:35.820 --> 00:02:38.700
if each of the parents'
organism cells are diploid,

00:02:38.700 --> 00:02:40.470
and offspring result from the fusion

00:02:40.470 --> 00:02:42.240
of cells from two parents,

00:02:42.240 --> 00:02:44.400
how do the offspring
of sexual reproduction

00:02:44.400 --> 00:02:47.220
maintain the same number of chromosomes?

00:02:47.220 --> 00:02:50.047
Well, diploid organisms
form gait that are haploid,

00:02:50.047 --> 00:02:53.850
meaning that they only contain
one set of chromosomes.

00:02:53.850 --> 00:02:56.550
When you hear the word
haploid, you can think of half,

00:02:56.550 --> 00:02:58.800
because haploid cells have half the amount

00:02:58.800 --> 00:03:01.920
of genetic information
than diploid cells have.

00:03:01.920 --> 00:03:03.990
A human haploid gamete, for example,

00:03:03.990 --> 00:03:08.340
contains 23 single chromosomes,
one of each homologous pair.

00:03:08.340 --> 00:03:10.470
When gametes fuse during fertilization,

00:03:10.470 --> 00:03:13.920
that brings the total number
of chromosomes back to 46,

00:03:13.920 --> 00:03:16.235
or 23 homologous pairs.

00:03:16.235 --> 00:03:20.400
So why is sexual
reproduction so important?

00:03:20.400 --> 00:03:23.520
Well, not only does it allow
organisms to produce offspring,

00:03:23.520 --> 00:03:27.150
but it also creates genetic
variation and diversity.

00:03:27.150 --> 00:03:29.250
The reason that offspring
have different traits

00:03:29.250 --> 00:03:30.570
compared to their parents,

00:03:30.570 --> 00:03:32.910
and that one sibling looks
different from another,

00:03:32.910 --> 00:03:35.940
can be attributed to sexual reproduction.

00:03:35.940 --> 00:03:39.000
This diagram here helps
illustrate how sexual reproduction

00:03:39.000 --> 00:03:41.100
creates genetic variation.

00:03:41.100 --> 00:03:44.580
The diagram shows a cross
between two hypothetical parents.

00:03:44.580 --> 00:03:45.747
It shows the chromosomes

00:03:45.747 --> 00:03:48.480
and the possible gametes
that the parents can form,

00:03:48.480 --> 00:03:52.320
and the possible chromosome
combinations in the offspring.

00:03:52.320 --> 00:03:53.153
So in the diagram,

00:03:53.153 --> 00:03:55.560
we can see that each
possible parent gamete

00:03:55.560 --> 00:03:58.950
contains one chromosome
from a homologous pair,

00:03:58.950 --> 00:04:00.360
and during fertilization,

00:04:00.360 --> 00:04:02.250
gametes from each parent fuse together,

00:04:02.250 --> 00:04:03.660
resulting in offspring

00:04:03.660 --> 00:04:07.170
that have a combination of
chromosomes from both parents,

00:04:07.170 --> 00:04:09.240
and this is where the genetic variability

00:04:09.240 --> 00:04:12.210
between parents and offspring comes from.

00:04:12.210 --> 00:04:15.030
Offspring are not genetically
identical to either parent

00:04:15.030 --> 00:04:18.780
because they contain a
mixture of genes from both.

00:04:18.780 --> 00:04:20.280
The diagram also shows us that,

00:04:20.280 --> 00:04:22.890
because each parent passes
on only one chromosome

00:04:22.890 --> 00:04:24.330
from each homologous pair,

00:04:24.330 --> 00:04:26.550
there are multiple
combinations of chromosomes

00:04:26.550 --> 00:04:28.470
that can occur in the offspring.

00:04:28.470 --> 00:04:31.080
For example, the pink
chromosome from parent one

00:04:31.080 --> 00:04:33.240
can be paired with the dark
chromosome from parent two

00:04:33.240 --> 00:04:34.440
in one offspring,

00:04:34.440 --> 00:04:36.990
and the light blue
chromosome from parent two

00:04:36.990 --> 00:04:38.640
in another offspring.

00:04:38.640 --> 00:04:41.370
Keep in mind that this diagram
only shows the inheritance

00:04:41.370 --> 00:04:42.872
of a single chromosome,

00:04:42.872 --> 00:04:47.370
but in humans, this occurs
for all 23 of our chromosomes,

00:04:47.370 --> 00:04:48.240
and as a result,

00:04:48.240 --> 00:04:50.760
there are millions of different
chromosome combinations

00:04:50.760 --> 00:04:53.010
that an offspring can inherit.

00:04:53.010 --> 00:04:56.820
This is why siblings can look
alike, but aren't identical.

00:04:56.820 --> 00:04:58.230
Even more mind blowing,

00:04:58.230 --> 00:05:00.120
there are other genetic processes

00:05:00.120 --> 00:05:01.740
that occur during fertilization

00:05:01.740 --> 00:05:04.230
that increase variation even more,

00:05:04.230 --> 00:05:07.710
resulting in trillions of
possible allele combinations

00:05:07.710 --> 00:05:09.390
for each offspring.

00:05:09.390 --> 00:05:12.450
This is why no two people
except monozygotic twins

00:05:12.450 --> 00:05:14.640
are genetically alike.

00:05:14.640 --> 00:05:17.490
To summarize, we learned that
sexual reproduction occurs

00:05:17.490 --> 00:05:21.030
when two haploid gametes fuse
together in fertilization,

00:05:21.030 --> 00:05:22.680
creating a diploid offspring

00:05:22.680 --> 00:05:25.080
with homologous chromosome pairs.

00:05:25.080 --> 00:05:27.870
We also learned that the patterns
of chromosome inheritance

00:05:27.870 --> 00:05:29.280
during sexual reproduction

00:05:29.280 --> 00:05:33.510
lead to genetic variation
in families and populations.

00:05:33.510 --> 00:05:34.890
It's why children look different

00:05:34.890 --> 00:05:38.550
from their biological
parents, brothers, or sisters.

00:05:38.550 --> 00:05:41.250
We've all inherited
different sets of chromosomes

00:05:41.250 --> 00:05:43.260
because of sexual reproduction,

00:05:43.260 --> 00:05:46.953
which in turn makes each and
every one of us one of a kind.


Introduction to Middle school Earth and space science

Language: en

00:00:00.240 --> 00:00:01.073
- Hi everyone.

00:00:01.073 --> 00:00:05.010
Sal Khan here and I'm with
Iman Howard, who is our manager

00:00:05.010 --> 00:00:07.500
for all of our stem
content on Khan Academy.

00:00:07.500 --> 00:00:08.772
And we wanted to welcome you

00:00:08.772 --> 00:00:13.620
to the Middle school Earth
and Space Sciences course.

00:00:13.620 --> 00:00:17.100
Iman, why should folks
be excited about this?

00:00:17.100 --> 00:00:19.530
- So Middle school Earth and Space Science

00:00:19.530 --> 00:00:21.150
is really exciting

00:00:21.150 --> 00:00:22.350
because it's one of those areas

00:00:22.350 --> 00:00:26.310
of science that answers what's
happening in our universe.

00:00:26.310 --> 00:00:28.113
And then like when you dig in, you're like

00:00:28.113 --> 00:00:30.360
"What is happening in our universe?

00:00:30.360 --> 00:00:32.520
This is why we have seasons."

00:00:32.520 --> 00:00:36.090
And so we start like really
big, we go all the way

00:00:36.090 --> 00:00:39.690
to outer space and we figure
out sort of earth's position

00:00:39.690 --> 00:00:41.822
in our solar system and the relationship

00:00:41.822 --> 00:00:45.480
to gravity and our inner
planets and our outer planets.

00:00:45.480 --> 00:00:48.030
And then we keep digging
in and we finally figure

00:00:48.030 --> 00:00:50.850
out how Earth's position answers seasons.

00:00:50.850 --> 00:00:52.746
It's not because we get closer to the sun

00:00:52.746 --> 00:00:56.851
or how based on earth's
position, we look up at the moon

00:00:56.851 --> 00:00:59.686
and you'll see a lunar eclipse
or how you don't look up

00:00:59.686 --> 00:01:02.430
and look at a solar
eclipse, like seriously

00:01:02.430 --> 00:01:05.010
don't look up because
it'll hurt your corneas.

00:01:05.010 --> 00:01:08.100
And then we keep going
and we talk about water

00:01:08.100 --> 00:01:10.980
and how the same water
that you're drinking right

00:01:10.980 --> 00:01:14.880
now is the exact same
water that dinosaurs drink.

00:01:14.880 --> 00:01:17.850
And then we get into the
rock cycle and we figure

00:01:17.850 --> 00:01:22.290
out why mountains are here and
how we're moving right now.

00:01:22.290 --> 00:01:25.295
Literally the plates below
us are moving and how

00:01:25.295 --> 00:01:29.160
at one point we could walk
across all the way from the US

00:01:29.160 --> 00:01:32.520
to Africa and how plate
tectonics really changed that.

00:01:32.520 --> 00:01:36.750
And then finally,
finally, we talk about us.

00:01:36.750 --> 00:01:38.190
We talk about us on this planet

00:01:38.190 --> 00:01:42.160
and how there's so many amazing
resources here and how well

00:01:43.154 --> 00:01:45.360
how we use them really impacts the earth

00:01:45.360 --> 00:01:47.220
and how that could impact our climate.

00:01:47.220 --> 00:01:48.930
And really awesome things that you can do

00:01:48.930 --> 00:01:50.850
as a learner to change all that

00:01:50.850 --> 00:01:53.250
and make this earth really awesome.

00:01:53.250 --> 00:01:55.530
What are you excited about, Sal?

00:01:55.530 --> 00:01:57.240
- Well, I'll just double
down everything you said

00:01:57.240 --> 00:01:59.070
and I like how you said
we're gonna dig into it

00:01:59.070 --> 00:02:02.070
'cause it's very appropriate
pun for earth, earth and space.

00:02:02.957 --> 00:02:05.047
This starts to answer the questions of,

00:02:05.047 --> 00:02:08.100
the from the cosmos to earth.

00:02:08.100 --> 00:02:12.192
Over billions of years, as you
mentioned, the earth is alive

00:02:12.192 --> 00:02:14.580
in certain ways with the
plates are still moving

00:02:14.580 --> 00:02:17.370
it's active and we should
say at least, and you know

00:02:17.370 --> 00:02:18.930
we are part of the earth.

00:02:18.930 --> 00:02:20.850
Your point, the, the water in our bodies

00:02:20.850 --> 00:02:23.190
the air that we breathe,
it's the same water

00:02:23.190 --> 00:02:25.320
and earth that has been
been here and the air

00:02:25.320 --> 00:02:27.180
for billions and billions of years.

00:02:27.180 --> 00:02:29.400
So to be able to actually
understand that it,

00:02:29.400 --> 00:02:31.500
it actually gives me, gives me goosebumps.

00:02:32.350 --> 00:02:34.410
So I think folks will be very
excited about this course.

00:02:34.410 --> 00:02:35.243
- Absolutely.

00:02:35.243 --> 00:02:37.875
(upbeat music)


Using the Teacher Skills Report to drive differentiation on Khan Academy

WEBVTT
Kind: captions
Language: en

00:00:00.690 --> 00:00:02.850
- [Instructor] Today I
will show you how to use

00:00:02.850 --> 00:00:06.270
the Skills Overview report
in the teacher dashboard

00:00:06.270 --> 00:00:07.503
on Khan Academy.

00:00:08.340 --> 00:00:10.500
Once you have logged into Khan Academy,

00:00:10.500 --> 00:00:12.900
go to your teacher dashboard.

00:00:12.900 --> 00:00:14.790
Once you are in your teacher dashboard,

00:00:14.790 --> 00:00:17.550
on the left-hand panel, under Tools,

00:00:17.550 --> 00:00:20.010
click Activity overview.

00:00:20.010 --> 00:00:22.053
This will be the screen that will load.

00:00:22.890 --> 00:00:23.850
At the top,

00:00:23.850 --> 00:00:27.420
there are two tabs, Activity and Skills.

00:00:27.420 --> 00:00:30.330
Today we are gonna use the Skills tab.

00:00:30.330 --> 00:00:32.850
Once the Skills tab loads,

00:00:32.850 --> 00:00:35.700
you will have several options
on the top of the screen.

00:00:35.700 --> 00:00:38.700
You can choose the grade
that you wanna look at,

00:00:38.700 --> 00:00:42.480
the units that you wanna
look at, the mastery levels.

00:00:42.480 --> 00:00:45.030
And there's an additional
box that you can check

00:00:45.030 --> 00:00:48.093
if you just wanna see assigned skills.

00:00:48.990 --> 00:00:50.970
So as I scroll down,

00:00:50.970 --> 00:00:55.860
I see that there are 11
units and 148 skills.

00:00:55.860 --> 00:00:59.310
I'm just gonna look at the ratios unit.

00:00:59.310 --> 00:01:04.310
So if I click ratios, this
will expand the screen

00:01:04.770 --> 00:01:07.560
and I will be able to
see more information.

00:01:07.560 --> 00:01:09.900
So this is basic ratios.

00:01:09.900 --> 00:01:14.490
One of the skills, here's
the Common Core standard.

00:01:14.490 --> 00:01:17.730
And here is actually the exercise.

00:01:17.730 --> 00:01:19.710
I can look at the actual exercise

00:01:19.710 --> 00:01:21.750
that the students have completed.

00:01:21.750 --> 00:01:24.840
Under that, you will
see the mastery levels.

00:01:24.840 --> 00:01:27.060
If I hover over the mastery levels,

00:01:27.060 --> 00:01:28.410
it would explain to me

00:01:28.410 --> 00:01:31.350
exactly what the student had to complete

00:01:31.350 --> 00:01:33.693
in order to earn this mastery level.

00:01:35.040 --> 00:01:38.310
I can also assign this assignment

00:01:38.310 --> 00:01:41.430
back to the students
right from this screen.

00:01:41.430 --> 00:01:45.180
So if I click this blue
Assign this skill button,

00:01:45.180 --> 00:01:47.190
a popup screen will appear

00:01:47.190 --> 00:01:50.040
and it will allow me to
pick my question set,

00:01:50.040 --> 00:01:52.140
whether I wanna have a
different question set

00:01:52.140 --> 00:01:54.150
or the same question set.

00:01:54.150 --> 00:01:57.120
It would allow me to
select or deselect students

00:01:57.120 --> 00:01:59.490
that I want to have this assignment.

00:01:59.490 --> 00:02:02.160
I can choose the start
date, the start time,

00:02:02.160 --> 00:02:04.410
the due date, and the due time.

00:02:04.410 --> 00:02:06.783
And then I just click the Assign button.

00:02:08.520 --> 00:02:11.190
It will bring me back to this screen.

00:02:11.190 --> 00:02:13.830
This is a great snapshot
for you to be able

00:02:13.830 --> 00:02:18.000
to see what level students are
at for different skill levels

00:02:18.000 --> 00:02:20.580
and to make small groups and differentiate

00:02:20.580 --> 00:02:22.200
within your classroom.

00:02:22.200 --> 00:02:25.980
You can also take this data back to PLCs

00:02:25.980 --> 00:02:29.130
and revise your teaching instruction

00:02:29.130 --> 00:02:32.670
in order to suit the needs
of the different students

00:02:32.670 --> 00:02:34.347
and the different skillsets.

00:02:35.670 --> 00:02:37.860
Another thing you can do with this report

00:02:37.860 --> 00:02:40.530
is click on the individual student.

00:02:40.530 --> 00:02:42.330
If I click on Victoria,

00:02:42.330 --> 00:02:45.840
I will see just her
information at the top.

00:02:45.840 --> 00:02:50.400
Make sure everything that
you want to see is clicked.

00:02:50.400 --> 00:02:53.490
So I'm gonna look at just the ratio.

00:02:53.490 --> 00:02:57.003
So I'm gonna unselect everything
and just select ratios.

00:02:58.230 --> 00:03:03.230
And here I can see that out of 148 skills,

00:03:03.750 --> 00:03:05.760
she's practiced 13.

00:03:05.760 --> 00:03:08.583
Here is the mastery
levels that she's earned.

00:03:09.420 --> 00:03:11.790
And if I dig a little bit deeper,

00:03:11.790 --> 00:03:15.180
I can see that these are the
things that were assigned

00:03:15.180 --> 00:03:18.450
to Victoria here, her
current mastery levels.

00:03:18.450 --> 00:03:19.800
And I can actually look

00:03:19.800 --> 00:03:24.060
at the different assignments
that were assigned to her.

00:03:24.060 --> 00:03:27.870
This is a great tool for
parent teacher conferences

00:03:27.870 --> 00:03:32.870
or IEP meetings or for
individual student conferences.

00:03:33.810 --> 00:03:37.260
Now I'll go back to the main class page

00:03:37.260 --> 00:03:39.100
where I see all my students

00:03:41.250 --> 00:03:44.070
and I can go down to the next skill level

00:03:44.070 --> 00:03:46.680
and I can see the same exact information,

00:03:46.680 --> 00:03:48.960
what students are performing where,

00:03:48.960 --> 00:03:51.240
and I can also assign the skill,

00:03:51.240 --> 00:03:53.580
see the Common Core strand,

00:03:53.580 --> 00:03:56.670
and also look at the assignment.

00:03:56.670 --> 00:04:00.390
If you have any more questions
about how to use this report,

00:04:00.390 --> 00:04:03.960
please look for a link in
the description of this video

00:04:03.960 --> 00:04:07.830
in order to gain access to
more support from Khan Academy

about how to use this
report in your classroom.


Using the Administrator Skills Report to drive differentiation on Khan Academy

WEBVTT
Kind: captions
Language: en

00:00:00.360 --> 00:00:01.830
- [Instructor] Today
I'm gonna be showing you

00:00:01.830 --> 00:00:03.956
how to use the Skills Progress Report

00:00:03.956 --> 00:00:06.030
in the administrator dashboard

00:00:06.030 --> 00:00:08.700
in the Khan Academy platform.

00:00:08.700 --> 00:00:10.380
This is gonna be a great tool

00:00:10.380 --> 00:00:12.660
in order for you to support your teachers

00:00:12.660 --> 00:00:15.480
in differentiation in their classrooms.

00:00:15.480 --> 00:00:16.740
You can share this data

00:00:16.740 --> 00:00:21.720
with specific teachers,
PLCs, or department chairs.

00:00:21.720 --> 00:00:23.790
So once you log into Khan Academy,

00:00:23.790 --> 00:00:26.070
go head over to the left hand panel

00:00:26.070 --> 00:00:28.890
and you can click on
the skills progress tab.

00:00:28.890 --> 00:00:31.980
Once you click on that tab,
the screen that you see

00:00:31.980 --> 00:00:34.323
before you will pop up on your screen.

00:00:35.580 --> 00:00:38.010
This report has many filters

00:00:38.010 --> 00:00:39.720
so I'm gonna walk you through each one

00:00:39.720 --> 00:00:43.740
of them so you can see how
this can fit your needs.

00:00:43.740 --> 00:00:45.390
So the first is a date range.

00:00:45.390 --> 00:00:48.810
There's a dropdown menu
you can choose from today,

00:00:48.810 --> 00:00:52.680
the last seven days, the last
30 days, or a custom range.

00:00:52.680 --> 00:00:55.050
Maybe you wanna pick the first semester

00:00:55.050 --> 00:00:59.100
or the first six weeks or
nine weeks of a semester.

00:00:59.100 --> 00:01:02.490
So I have chosen May 4th
through September 26th.

00:01:02.490 --> 00:01:05.160
You can pick the Khan Academy
course of your choice.

00:01:05.160 --> 00:01:07.200
I have chosen algebra one.

00:01:07.200 --> 00:01:10.680
You can pick one school or many schools.

00:01:10.680 --> 00:01:13.650
For this example, I'm gonna
just choose one school.

00:01:13.650 --> 00:01:17.970
You can choose multiple
grades, the district course

00:01:17.970 --> 00:01:21.033
and the teacher or multiple teachers.

00:01:22.470 --> 00:01:24.750
So once you have all your filters in place

00:01:24.750 --> 00:01:27.120
you can go ahead and hit
the blue apply button

00:01:27.120 --> 00:01:29.133
and wait for the report to load.

00:01:31.140 --> 00:01:33.900
Once the report has
loaded, there will be two

00:01:33.900 --> 00:01:36.420
additional dropdown menus that appear.

00:01:36.420 --> 00:01:39.720
There's a unit view or a
combined view, and then

00:01:39.720 --> 00:01:43.830
you can choose how you wanna
see the report by skill level

00:01:43.830 --> 00:01:45.450
or number of students.

00:01:45.450 --> 00:01:48.600
So I have picked the number
of students high to low

00:01:48.600 --> 00:01:50.460
and then I'm gonna pick the unit review

00:01:50.460 --> 00:01:54.273
so I can see the specific units
and the skills in that unit.

00:01:55.260 --> 00:01:58.500
So as you can see in
bold letters, on the top

00:01:58.500 --> 00:02:02.610
of each chart there is the unit and then,

00:02:02.610 --> 00:02:05.523
and within that unit it tells
you there are seven skills.

00:02:06.540 --> 00:02:09.510
Over to the right, you
see the skill levels.

00:02:09.510 --> 00:02:13.020
The darkest purple is the most mastered

00:02:13.020 --> 00:02:15.513
and the lightest is attempted.

00:02:16.950 --> 00:02:20.220
Once you look at each skill,
they're listed in bold

00:02:20.220 --> 00:02:22.950
above each bar and the
common core standards

00:02:22.950 --> 00:02:24.480
are right next to it.

00:02:24.480 --> 00:02:27.090
So I'm gonna look for the lightest purple.

00:02:27.090 --> 00:02:29.640
And the first one I see
is combining like terms

00:02:29.640 --> 00:02:32.520
with negative coefficients
and distribution.

00:02:32.520 --> 00:02:35.220
So I'm gonna click on this
and I see that there's three

00:02:35.220 --> 00:02:37.470
students, Jason, Carla, and Chelsea

00:02:37.470 --> 00:02:39.360
that may need some more support.

00:02:39.360 --> 00:02:43.650
But I see that students
seem to be very successful

00:02:43.650 --> 00:02:46.263
in equivalent expressions.

00:02:47.760 --> 00:02:50.280
So you wanna do your comparison.

00:02:50.280 --> 00:02:52.830
You may wanna look at individual teachers

00:02:52.830 --> 00:02:55.860
or you may wanna compare
teachers that teach

00:02:55.860 --> 00:02:59.970
the same skill to see where
we need to make changes

00:02:59.970 --> 00:03:02.910
in teaching that specific skills

00:03:02.910 --> 00:03:05.760
to students or where we
may need intervention,

00:03:05.760 --> 00:03:09.540
remediation or acceleration.

00:03:09.540 --> 00:03:12.750
So the best thing that you can do is

00:03:12.750 --> 00:03:15.510
either take a screenshot
and share with your teachers

00:03:15.510 --> 00:03:18.840
or use the CSV export that is right up

00:03:18.840 --> 00:03:21.690
on top or the blue download arrow

00:03:21.690 --> 00:03:24.090
so that you can export this report

00:03:24.090 --> 00:03:28.470
and share it with the teachers
that need the information.

00:03:28.470 --> 00:03:32.880
If you need more support on
this skills progress data,

00:03:32.880 --> 00:03:35.580
please contact your
district success manager

00:03:35.580 --> 00:03:39.090
and they'll be more than happy
to give you some more support

00:03:39.090 --> 00:03:41.493
and tips on how to use this with teachers.


What are common scams I should be aware of?

WEBVTT
Kind: captions
Language: en

00:00:05.970 --> 00:00:06.990
- So Grace, you know,

00:00:06.990 --> 00:00:09.030
and I'm asking both to protect all of us

00:00:09.030 --> 00:00:13.620
but also I have a strange
fascination of, of exotic scams.

00:00:13.620 --> 00:00:15.450
What, what are the types
of scams that you've seen?

00:00:15.450 --> 00:00:18.540
How, how elaborate have,
have these things become?

00:00:18.540 --> 00:00:20.520
- Yeah, so unfortunately the attackers

00:00:20.520 --> 00:00:21.840
are getting more creative.

00:00:21.840 --> 00:00:23.730
Now, the good news is that

00:00:23.730 --> 00:00:26.970
most major, you know,
email platforms for example

00:00:26.970 --> 00:00:29.940
are automatically blocking
all kinds of spam that,

00:00:29.940 --> 00:00:34.110
or scams and spam that you
never see on a regular basis.

00:00:34.110 --> 00:00:36.840
For example, during the Covid Pandemic,

00:00:36.840 --> 00:00:40.260
Google blocked 18 million
Covid impersonation

00:00:40.260 --> 00:00:41.730
emails per day.

00:00:41.730 --> 00:00:43.590
And that is something that never made it

00:00:43.590 --> 00:00:45.180
to people's inboxes.

00:00:45.180 --> 00:00:48.120
- What is a Covid impersonation email?

00:00:48.120 --> 00:00:50.880
- So unfortunately, one
thing to look out for

00:00:50.880 --> 00:00:54.030
with these scams is folks impersonating

00:00:54.030 --> 00:00:56.370
what you might think
of as a trusted source.

00:00:56.370 --> 00:01:00.120
So maybe a hospital or health organization

00:01:00.120 --> 00:01:02.550
reaching out with Covid information,

00:01:02.550 --> 00:01:05.850
kind of trying to beat people
in with something timely.

00:01:05.850 --> 00:01:08.220
So we do really recommend that folks

00:01:08.220 --> 00:01:12.210
go directly to the trusted
website of that organization

00:01:12.210 --> 00:01:15.150
as opposed to clicking into a link

00:01:15.150 --> 00:01:16.860
that may look a little bit suspicious

00:01:16.860 --> 00:01:19.290
or may not be something
they were expected to hear.

00:01:19.290 --> 00:01:24.290
Another flag is if a
email or a call or a text

00:01:24.660 --> 00:01:26.190
is really trying to rush you

00:01:26.190 --> 00:01:28.260
into providing personal information,

00:01:28.260 --> 00:01:30.120
such as your bank account information,

00:01:30.120 --> 00:01:32.640
your password, or otherwise.

00:01:32.640 --> 00:01:35.010
So we, we were seeing trends of attempts

00:01:35.010 --> 00:01:37.440
to kind of reach out and say, help now or

00:01:37.440 --> 00:01:39.180
please send money here.

00:01:39.180 --> 00:01:41.400
We, we are also seeing
impersonation attempts

00:01:41.400 --> 00:01:43.320
around special offers.

00:01:43.320 --> 00:01:46.170
So, you know, if it
looks too good to be true

00:01:46.170 --> 00:01:50.220
it probably is, if you're
being offered free items

00:01:50.220 --> 00:01:51.780
that are high monetary value,

00:01:51.780 --> 00:01:54.060
but you're being asked
to immediately, you know,

00:01:54.060 --> 00:01:56.250
put your credit card information down

00:01:56.250 --> 00:01:59.000
and that's definitely another
red flag to look out for.

00:02:00.030 --> 00:02:02.520
- Wow. It, it is a dangerous world

00:02:02.520 --> 00:02:04.860
but I'm glad there are
folks like you who are,

00:02:04.860 --> 00:02:06.780
are helping keep dragging.

00:02:06.780 --> 00:02:08.280
It feels like it's a
never ending arms race

00:02:08.280 --> 00:02:10.290
so we have to stay vigilant.

00:02:10.290 --> 00:02:12.270
- Definitely. I think
that's our biggest tip

00:02:12.270 --> 00:02:14.940
is to be proactive and definitely

00:02:14.940 --> 00:02:17.980
take a bit before clicking
on something suspicious

00:02:18.840 --> 00:02:20.550
and, and, and verify, you know

00:02:20.550 --> 00:02:22.380
if there's a, you receive something

00:02:22.380 --> 00:02:24.570
you think it looks like
it's from someone you know

00:02:24.570 --> 00:02:26.640
or something you're familiar with,

00:02:26.640 --> 00:02:28.710
go ahead and find another way to confirm

00:02:28.710 --> 00:02:30.750
that that's actually the case.

00:02:30.750 --> 00:02:33.060
- And always check the link
you're about to click on

00:02:33.060 --> 00:02:34.890
and before you type in a password,

00:02:34.890 --> 00:02:38.790
think three times are my takeaways.

00:02:38.790 --> 00:02:40.620
And two step verification.

00:02:40.620 --> 00:02:41.463
- Absolutely.

00:02:42.840 --> 00:02:45.720
- Thanks so much, Grace,
that was really useful.

00:02:45.720 --> 00:02:46.553
- Thank you Sal.


What can I do to protect my account?

WEBVTT
Kind: captions
Language: en

00:00:00.300 --> 00:00:03.180
- So Grace, is there anything
that I can proactively do,

00:00:03.180 --> 00:00:04.623
to protect my accounts?

00:00:05.760 --> 00:00:07.702
- Absolutely. I'm so glad you asked.

00:00:07.702 --> 00:00:10.410
We recommend that folks use something

00:00:10.410 --> 00:00:12.690
called two-step verification.

00:00:12.690 --> 00:00:15.120
Now you have a password
to log into your account.

00:00:15.120 --> 00:00:18.180
But if you are able to turn
on two-step verification,

00:00:18.180 --> 00:00:21.210
that is a second layer of authentication

00:00:21.210 --> 00:00:23.220
to verify that you are you.

00:00:23.220 --> 00:00:25.590
This is extremely helpful in the event

00:00:25.590 --> 00:00:29.340
that a password is stolen
through a phishing attempt

00:00:29.340 --> 00:00:32.760
because even if someone has
access to your password,

00:00:32.760 --> 00:00:35.070
they won't be able to
log into your account

00:00:35.070 --> 00:00:38.400
without also having your
phone, or your computer,

00:00:38.400 --> 00:00:40.230
which is far less likely.

00:00:40.230 --> 00:00:42.180
So, two-step verification can mean

00:00:42.180 --> 00:00:44.700
receiving a text message
to verify that it's you,

00:00:44.700 --> 00:00:46.860
or an email, or even a phone call.

00:00:46.860 --> 00:00:49.320
This is something we
really recommend people do,

00:00:49.320 --> 00:00:51.240
especially for things like bank accounts,

00:00:51.240 --> 00:00:53.070
or any sort of account

00:00:53.070 --> 00:00:55.320
where you have a lot of
personal information.

00:00:55.320 --> 00:00:57.120
- No, I can't tell you how
important that is, Grace.

00:00:57.120 --> 00:00:59.792
I use two-step verification
on pretty much any account

00:00:59.792 --> 00:01:03.540
that I definitely do not
want people to break into.

00:01:03.540 --> 00:01:05.850
And I have to say, over the
last four or five years,

00:01:05.850 --> 00:01:07.740
there's been a few situations
where all of a sudden,

00:01:07.740 --> 00:01:09.397
I got a text message on my phone saying,

00:01:09.397 --> 00:01:10.710
"Here's your security code."

00:01:10.710 --> 00:01:13.350
And I'm like, "Wait, I didn't
even ask for a security code."

00:01:13.350 --> 00:01:16.200
It means someone might have
compromised one of my accounts,

00:01:16.200 --> 00:01:17.790
and is trying to log in.

00:01:17.790 --> 00:01:21.570
But the two-step verification
is actually keeping them out.

00:01:21.570 --> 00:01:24.472
Because the odds that someone
got your password somehow,

00:01:24.472 --> 00:01:26.880
and has physical possession of your phone,

00:01:26.880 --> 00:01:28.980
or a computer, very, very low,

00:01:28.980 --> 00:01:31.470
unless you have some shady
people in your house,

00:01:31.470 --> 00:01:32.893
or your workplace.

00:01:32.893 --> 00:01:34.770
- That's absolutely right, Sal.

00:01:34.770 --> 00:01:37.357
And the fact that you
received that message

00:01:37.357 --> 00:01:40.170
and immediately said,
"Hey, this wasn't me."

00:01:40.170 --> 00:01:43.380
That's two step verification
working as intended.

00:01:43.380 --> 00:01:45.720
Another tool that I like to
recommend that folks use,

00:01:45.720 --> 00:01:48.030
is something called the password manager.

00:01:48.030 --> 00:01:50.160
This can help you keep
track of your passwords,

00:01:50.160 --> 00:01:53.070
and make sure that you're
using strong passwords,

00:01:53.070 --> 00:01:54.930
and updating them regularly.

00:01:54.930 --> 00:01:57.600
So you can save your
passwords in your browser.

00:01:57.600 --> 00:01:59.160
So, instead of having to keep track

00:01:59.160 --> 00:02:00.960
of 20 different passwords yourself,

00:02:00.960 --> 00:02:03.000
that tool does it for you.

00:02:03.000 --> 00:02:04.020
- No, that's really helpful.

00:02:04.020 --> 00:02:05.790
Because I think there can
be a strong temptation

00:02:05.790 --> 00:02:09.300
to put easy passwords, or
reuse the same password

00:02:09.300 --> 00:02:12.050
over and over again, to
just make it memorable.

00:02:12.050 --> 00:02:15.180
But that makes you extra vulnerable.

00:02:15.180 --> 00:02:16.140
So if you use these things,

00:02:16.140 --> 00:02:18.416
you can have super secure,
different passwords

00:02:18.416 --> 00:02:19.803
for every site.

00:02:20.760 --> 00:02:21.690
- Exactly.

00:02:21.690 --> 00:02:24.840
Unfortunately many people
do reuse the same password,

00:02:24.840 --> 00:02:27.420
or use a, not a very secure password

00:02:27.420 --> 00:02:28.950
that might be easy to guess.

00:02:28.950 --> 00:02:32.250
So we really recommend to move
over to that password manager

00:02:32.250 --> 00:02:35.190
and then you only have to
remember one password to that.

00:02:35.190 --> 00:02:36.480
Super helpful.

00:02:36.480 --> 00:02:39.090
Another tool that I
recommend people look into

00:02:39.090 --> 00:02:41.250
is something called Security Checkup.

00:02:41.250 --> 00:02:43.590
That's a place where you
can actually keep track

00:02:43.590 --> 00:02:45.900
of all your online accounts and passwords,

00:02:45.900 --> 00:02:49.650
and be notified if there is a
breach, such as a data breach,

00:02:49.650 --> 00:02:53.190
or a phishing attempt that
got access to your password.

00:02:53.190 --> 00:02:54.120
It'll help you keep track

00:02:54.120 --> 00:02:55.470
of kind of how long those passwords

00:02:55.470 --> 00:02:57.780
have been staying the same,
and remind you to update them.

00:02:57.780 --> 00:03:00.720
So, definitely check out
Security Checkup as well.

00:03:00.720 --> 00:03:02.673
- Super useful. Thanks so much, Grace.

00:03:03.510 --> 00:03:04.440
- Thank you, Sal.


Wait have I just been attacked? What do I do now?

00:00:06.120 --> 00:00:06.953
- All right, Grace.

00:00:06.953 --> 00:00:10.170
So ideally we can recognize
when we are attacked,

00:00:10.170 --> 00:00:12.090
but let's say we begin to fall for it.

00:00:12.090 --> 00:00:13.980
Let's say there's a
phishing attack and we go,

00:00:13.980 --> 00:00:16.380
we click really fast
cause we're all panicked.

00:00:16.380 --> 00:00:18.827
We type in our password
and they're like, oh wait,

00:00:18.827 --> 00:00:21.867
I think I just gave my
password to a shady site.

00:00:21.867 --> 00:00:25.383
What do you do once you're
compromised in some way?

00:00:26.580 --> 00:00:27.630
- It's a great question, Sal.

00:00:27.630 --> 00:00:28.980
Now this is really unfortunate.

00:00:28.980 --> 00:00:30.540
We hope this doesn't happen to folks,

00:00:30.540 --> 00:00:33.330
but if it does, there are
a few steps you can take

00:00:33.330 --> 00:00:34.680
to help mitigate the fallout

00:00:34.680 --> 00:00:36.259
from this kind of phishing attack.

00:00:36.259 --> 00:00:39.579
You should immediately tell
a trusted adult, a teacher,

00:00:39.579 --> 00:00:43.080
or a parent, and let them know
that this happened to you.

00:00:43.080 --> 00:00:45.162
This will also help them make others aware

00:00:45.162 --> 00:00:48.180
that if they are hearing
from you on that account

00:00:48.180 --> 00:00:49.522
that's been compromised,

00:00:49.522 --> 00:00:51.450
so that other folks don't fall

00:00:51.450 --> 00:00:54.004
into the same hands of the scammer.

00:00:54.004 --> 00:00:56.730
This will also help you take steps

00:00:56.730 --> 00:00:59.970
to report the scam if possible.

00:00:59.970 --> 00:01:02.070
So, for example, if you're using Gmail,

00:01:02.070 --> 00:01:05.813
there is a reporting
tool within your email.

00:01:05.813 --> 00:01:09.600
Oftentimes you can get
alerts on your phone

00:01:09.600 --> 00:01:12.660
if there are phone calls
that look like a scam,

00:01:12.660 --> 00:01:14.850
but there are also ways
that you can report that.

00:01:14.850 --> 00:01:17.010
So definitely work with a trusted adult

00:01:17.010 --> 00:01:18.912
if you think that this
has happened to you.

00:01:18.912 --> 00:01:22.650
And then once you've kind
of mitigated the fallout

00:01:22.650 --> 00:01:26.580
from that, you can look at
best practices to make sure

00:01:26.580 --> 00:01:30.330
that that password isn't
compromised in other places.

00:01:30.330 --> 00:01:33.699
So you are going to want
to update that password,

00:01:33.699 --> 00:01:37.391
enroll in two step verification
as we talked about,

00:01:37.391 --> 00:01:40.320
and make sure that on a regular basis

00:01:40.320 --> 00:01:41.580
you're changing your password.

00:01:41.580 --> 00:01:44.342
So even if this happens to you
and you weren't made aware,

00:01:44.342 --> 00:01:47.730
you can actually mitigate
some of that risk

00:01:47.730 --> 00:01:49.890
if you're updating and
having strong passwords

00:01:49.890 --> 00:01:51.317
on a frequent basis.

00:01:51.317 --> 00:01:54.244
There's another nifty tool
called Security Checkup

00:01:54.244 --> 00:01:57.480
that can actually help you
check on your passwords

00:01:57.480 --> 00:02:01.200
for all of your accounts where
you use your email to log in.

00:02:01.200 --> 00:02:02.760
And that helps you keep
track and make sure

00:02:02.760 --> 00:02:04.613
that you know your
passwords aren't outdated

00:02:04.613 --> 00:02:07.350
or you know, worst case scenario

00:02:07.350 --> 00:02:08.520
that they haven't been breached

00:02:08.520 --> 00:02:10.928
in some kind of data breach
or a phishing attempt.

00:02:10.928 --> 00:02:12.603
- Super, super useful.
