All my best teachers were trained as teachers, and weren’t necessarily content experts.

One of the worst teachers I ever had, was a genius Calc II teacher, who was an abusive asshole, and would humiliate students for asking questions he deemed as “stupid.”

Since a significant part of my learning, is asking “stupid” questions, this did not go well for me, and I took an Incomplete. I had a 4.0, to that point.
