I also taught courses at other levels, Phys-2170 “Foundations of Modern Physics” and Phys-4230 “Thermodynamics and statistical mechanics”. In both cases, I extensively used clickers, combining the blackboard-style teaching with the use of PowerPoint slides. I also had an opportunity to teach two sections of Phys-1140 undergraduate labs. The overall large number and different types and levels of courses that I taught at CU helped me to better understand how very much I genuinely enjoy teaching at all levels.
