Interesting article from 1990. Some school districts must have listened to him or others with the same criticisms. What has truly amazed me with our school district's math curriculum over the last dozen years (only time period I have actual first-hand knowledge) is the breadth of the curriculum. The tree is certainly far less spindly than when I went to school in the 1970's and 1980's. For example, there is kiddie algebra and graphs from second grade, probabilities/statistics and solids geometry from third grade as well as an emphasis on constructed responses/mini-proofs once the students can write well in second grade. That emphasis has also translated to state tests and county tests also requiring constructed responses in math and lots of essay writing in reading.
