Marshall Lassak has written an article about Using dynamic graphs to reveal student reasoning. This article was published earlier this month in International Journal of Mathematical Education in Science and Technology. Here is the (rather short) abstract of the article:
Using dynamic graphs, future secondary mathematics teachers were able to represent and communicate their understanding of a brief mathematical investigation in a way that a symbolic proof of the problem could not. Four different student work samples are discussed.

Sounds like fascinating stuff! I am trying to extend the limitless possibilities of math that I have taught to my children to other parents. Math education research sounds like the field for me. On my new blog I only want to stress how to teach math to you young children and not just math. Does that make sense? www.doyouspeakmath.blogspot.com
