TED
Sal Khan of Khan Academy argues that schools push students forward with gaps in their foundations, and that students should instead master concepts at their own pace. He compares it to building a house on an unfinished foundation.
HN commenters cite it when discussing how gaps in basic knowledge pile up and how mastery learning could fix that.
