Remember that not everything your instructors say will work because several schools have changed since these instructors were working in the field of public education. Heck, the whole U. S. has changed drastically in the past decade. Many years ago, I had a retired instructor for a teaching credential class and when I applied his suggestions to my own classroom, the students behaved even worse than before! I quickly realized that this instructor had not been a classroom teacher in over 20 years at that point. Besides, he had taught in a high-achieving school with highly supportive parents, which was the extreme opposite of the teaching arrangement that I was given at the time. At that point, I thought about how much I would have liked to see this instructor himself handle a rough class at that rough school with no support from the administrators. In recent years I have found that educators who are judgmental aren't much or any better at their jobs themselves.
