After reading Margaret Donaldson's wonderful 'Children's Minds,' I wanted more immersion in the source material covered second hand in my teaching credential program. Piaget was a god, but we never read him. Now, after struggling through this summary of his work produced for a broader audience, I can tell you Piaget is very, very challenging to read, even in 'dumbed-down' form. In the future, I might use excerpts from this as an example of dense prose requiring full engagement when I tell children that adults often have trouble understanding what they read, too. The effort sometimes rewarded me, but it was a real and serious effort.
