Terry, You make a very good point about the value of a dedicated instructor no matter the setting. Yes, we need to have a comfortable supportive environment in which our students can learn but the real factor is the instructor. When I was in teacher training my professor warned me that technology would soon replace all live instructors. Really motivated me because I was training to enter a field in which I would soon be replaced. As history has shown the human factor in teaching is essential and in spite of all the advances in technology teachers are still needed. Gary Gary Meers, Ed.D.
