In my view, this points to the thought that education requires two components: first, the presentation of materials by a teacher; and second, willingness to receive those materials by the student. In some places, such as Japan and South Korea, the latter is accomplished by fostering intense competition. This article presents an alternative. Perhaps the merits of these and other alternatives for creating a willingness to learn are debatable, but it seems rather dismissive to suggest, as the initial comment does, that more teaching is the whole answer.
I do sympathize with the initial's commenter's complaint that teaching has too much moved to what are essentially therapy sessions for children. The problem does seem to be a lack of balance, with a focus too strong on making children willing to open their minds, without providing anything to put inside.
