Having taught computer networking at the college level for the last 10 years I don't think I have ever taught a class the same way twice. I am always discovering new ways of doing things, items that I would do differently, and just trying to learn from my mistakes and what works and doesn't. I think an Instructor has to always be flexible in accepting change. I'm always interested in how other instructors do things in their classroom. There are some classes where the whole thing just feels boring to me and so I have to mix it up. Sometimes students ask valid questions that take more time to answer than I planned for but I actually enjoy that. It makes for a much more active room and then I can bring it all back to how it relates to the original topic. Rod Wright
