I had always considered the amount of influence an instructor can have on how a class can learn and facilitate learning. However, I never quite thought about how their own personal beliefs or thoughts can become a barrier.
I can't imagine an instructor not caring at all if their students but I can see how an inexperienced instructor can be timid or not so confident in trying new approaches of facilitating learning. I was there once, I can admit, but am glad that I have been able to develop as an instructor to better service our students.
