So Andrew and his students went in, looked at some of those assignments, understood the root cause of the misconception, and then they produced a targeted error message that would be provided to every student whose answer fell into that bucket, which means that students who made that same mistake would now get personalized feedback telling them how to fix their misconception much more effectively.
Tā nu Endrjū un viņa studenti  tam pievērsās, izpētīja dažus no šiem uzdevumiem, saprata, kāpēc rodas šāds pārpratums, un izveidoja īpašu kļūdas paziņojumu, ko saņēma ikviens students, kura atbildē iekrita šajā „caurumā”. Studenti, kuri pieļauj to pašu kļūdu, tagad saņem personalizētu atgriezenisko saiti, kas ļauj viņiem daudz efektīvāk  novērst šo pārpratumu.
