I have been a math and science educator since 1965. I have an interest in helping students and teachers develop programming skills. I currently teach a one-semester, two-unit programming course to middle school and secondary math teachers. I currently use Scratch in the course and one of the purposes of this blog is to maintain contact with teachers that want to continue programming in Scratch after they have finished the course. Also, I am always working on a program and this blog and the Scratch web site are the two places where I can share my projects.
