Just from my own personal experience, I disliked math classes, but I was terrified by my Spanish class. Something about class participation in another language filled me with dread, and I learned to absolutely hate it. It seemed tedious and stressful at the same time to me, I felt so stupid. Now I'm more sure of myself and could probably do just fine, but it was a big missed opportunity, and that's a skill I wish I had now. Underlying this is the fact that teaching is a discipline by itself. Understanding the material is maybe halfway to quality teaching.
