That big 3rd paragraph seems to be the center of bogosity. "Her comparison helps to delineate differences between the two groups and provides a useful format for discussions." Translated that means - this is some bogus education theory that has no scientific basis behind it, and if you take action based on it, then whatever mess you create is your own fault.

I had to take a survey course on education research during my postgrad days - the first thing the prof said was that basically education is a research ghetto where every half-baked methodology, and every bit of post-modern drivel can find a home.
