Classroom's are full of students so teacher's cant tell wheather a student's is bored, or confused with a lesson so if the tecnology was valuable the lesson could be changed in the text it state's "A classroom computer could reconize when a student is becoming confused or bored," Dr. Huang predicts."Then it could modify the lesson, like an effective human instructor." So if classrooms had this tecnology it would be slightly better for students to learn without being bored or confused.
