Any person with a minimum sufficient experience in life has been rewarded with failure. A subset of those people, with sufficient practice, will come to recognize failure, not as a friend, but as a teacher. A recent useful (and ultimately harmless) failure in my class became a key teaching moment, […]

Failure as a Teacher’s Aid

Tomorrow, my spring teaching begins. Again, I am teaching “Introductory Mechanics” (PHYS 1303), our 1st-semester introductory physics course.

By my own recollection, it was the spring of my second year in college. I was a sophomore who had stumbled in my physics and math classes at Yale. I had tasted what it was to no longer be the best student in your classes, and it was hard to […]
