The site is looking great, by the way.

The comment I would make is that I think it is important to remember that the developmental work can be useful to teachers. Although the strict stage structure is wrong, many of the features of children’s thinking that developmental psychologists have identified are quite real. (I mentioned this in the article.)

I tried to make that point clear in the post by by distinguishing between Piaget’s patterns of thinking and the strict stage-like organization of those patterns that has been falsified by more recent research. Even when they march to different drummers, children still exhibit well-understood patterns in the ways they construct an understanding of the world, and we do well as parents to learn from the scholars who study those developmental patterns.

It’s a point that bears repeating, because although announcing that some grand theory has been overturned may be good rhetoric (grabbing attention or stroking our populist egos), it is rarely how science actually proceeds. The truth is usually more complicated.
