Teaching Philosophy

I retired from formal teaching in 2020. My goal in the classroom and laboratory was to help students understand the natural world by logically dissecting it, then finding out how it all fit back together. If my students could develop ways of thinking that challenged their established assumptions, then I succeeded. I provided my classes the known information on a subject, but did not expect them to memorize these great webs of information. Rather, I wanted the students to interpret the significance of these facts in a greater context. I allowed them to make mistakes in their “logical” thinking, then I could use these mistakes as a platform for a constructive discussion with them. Using these tools, I believe students truly learned the material in a useful manner, one which would carry them forth well after any class they took with me.
