It turns out the program in the video is based on the following research that was done in 1987: http://pat-thompson.net/PDFversions/1987StrucInAlg.pdf This research indicates that students as low as the 7th grade should have no problems learning math using expression trees. I have not tested the program with students this young yet, but I have tested it with the college freshman I teach, and it has been able to fix long held misconceptions a number of them had about how math works. > Another idea: Why not break the 20 or so steps to solve a problem down > to questions?

However, how would the software know why the user answered incorrectly when they do? Ted -- You received this message because you are subscribed to the Google Groups "sage-edu" group.
