Have you checked the "Articles" section on betterexplained.com? Clearly the author of the article is trying to put his ideas into practice - not perfect but rather helpful in fostering something like actual understanding of topics that are all too often presented as a sequence of rote manipulations (more or less all of K12 and many "service" university courses follow this).

dvse, see my response to kalid. I thought "Math Wars" was a reference to a specific set of criticisms levied against Kahn Academy recently, when perhaps it was not a reference to that at all. If so, the whole thing could be a misunderstanding on my part. Waiting for kalid to clarify.
