You indicate that you also teach physics. Instead of just patching on technology because you think you need to, be constructive. Go over to Vernier or Pasco and start looking at the tools for interactive learning. At my school, we make extensive use of computers and sensors in our physics and physical science classes. The students are happier, the technology is actually doing something useful, and it allows you do do much more in less time. I also create PowerPoints for all of my classes as well as create a class site using Blackboard software.
