As we know, curriculae like Everyday Math, Core Math, Reading Recovery, Balanced Literacy and the Literacy Collaborative are based on the constructivist theory of education. Indeed, the Literacy Collaborative (a trademarked name for Balanced Literacy) states that its framework is based on the theories of Vygotsky, Bruner and Clay.
For an interesting exercise, do a google search with all three of these keywords “constructivist marxism vygotsky” [ask | clusty | google | msn | yahoo]
Now before the constructivists out there accuse me of labelling them as marxists, let me say I am not. I am, however, making the point that the curriculae you advocate has deep roots in marxist egalitarian theory.
