Maybe some will be offended by this post by Greg but I do think he raises some relevant points. Was glad to notice that the teacher training I’m involved is not too bad when looking at these 5 points. We do teach about Piaget more as a part of history and to explain how developmental research is conducted and how this evolved with thus mentioning all the flaws. But we also note that the idea of starting of in the concrete – in part inspired by Piaget – still is very important.
