A few things spring from this video that are wholly systemic thinking:
1) why do we allow children to progress in school when they haven't fully mastered concepts?
2) even though kids get a regular report card based on tests and homework, why has that been the only feedback available?
The concept of assigning grades every quarter or semester is totally antiquated and leaves loads of kids unable to follow concepts in future simply because they were allowed to "pass" a subject even though they didn't master it. That's just dumb. Mastery is what we seek from education, not good grades. Just like our obsession with money can take us away from what we really need, our obsession with grades can distract us from what we must learn.
Systems demand closed information loops in order to function optimally. With teachers able to monitor not only what exercises their kids did but also what exercise questions they attempted, which questions they got wrong, and how long they spent on each video and question, teachers can guide their students' education without ever having to embarrass them in front of peers. The feedback loop in this system is finally closed, and it allows students, in effect, to direct their own education. The fact that the teacher can then assign tutors from the class to assist their students who haven't totally mastered all topics frees up the teacher from both doing lectures and attempting to help all the students all the time. Some kids just need a nudge, they can get that from other students. Some kids need teacher support, and by using this feedback, the teacher manages the education of the entire class, pupil by pupil, without much effort at all. All my teacher friends keep telling me they want to be an educator, not an administrator. Well, this should be their dream.
