I started teaching computing in February 1980. I was 17 in my senior year of high school, and I taught "Bits, Bytes, and Basic" in a community education class. I taught through my undergrad years--community education, afterschool classes, GED classes, and even community college in 1984. I read "Personal Dynamic Media" by Adele Goldberg and Alan Kay while on an internship at Bell Labs in 1982. I'd never before thought about computing FOR learning (as opposed to learning ABOUT computing). Adele and Alan's thoughts and words set me on the road to my PhD in Education and Computer Science at the University of Michigan in 1993. Nowadays, I focus on using lessons from learning sciences and educational technology for teaching about computing.
