Like so many others, I had to go through the OOP learning process before I could appreciate what OOP was all about. I have a feeling that there are a lot of people out there who still feel that way.

Each time I teach a programming class, I learn new and better ways to explain things. When I look out across a classroom filled with students and it looks like a still-life painting, it's time to back off, retool, and try a different approach to whatever concept it is I'm trying to teach. Every class I've taught has offered new perspectives on how I teach and how students learn. I've had the opportunity to teach both in a university setting and on site at various companies both here and in Europe. Each experience presented different teaching challenges.
