Taking classes really helps one gain perspective on what things are like from the student's point of view, and is highly recommended for all instructors. If you have a co-instructor, have him or her teach the class, while you attend as the student. You may notice a disturbing trend. Most dogs would just quit on you. And yet, we expect our human students to respond to it.
Teaching is a difficult thing to learn to do well.
It does not come naturally, but many aspects of teaching can be learned. Teaching people is remarkably similar to teaching dogs. People respond or fail to respond to the same types of things as dogs do. People are all different, and what works for one student may not work for another. Unfortunately, most of us learned by coercion.
