History Repeats Itself

As I read Chapter one of the R&J book, something occurs to me. It seems that EC's teaching philosophy is cyclical. For example, children in the 18th century sat in solitude and memorized facts and Scriptures then Pestalozzi introduced interactions with teachers and peers as well as the concept of Anschauung. Then preschools tended to thought of as a place to put the kids while the poor parents had to work and a stigma was attached. Froebel combated that mentality. . .and so on.

As we look at the current landscape, do you agree with this analysis of the field of child development and if you do, where do you think we are in the cycle? DAP is currently the new hot topic, but how prevalent is it in preschool and elementary schools? Is DAP on it's way in or out? Do you think DAP will fall away as well as other philosphies or is it here to stay?
