This had mixed results, primarily because students comprehend and answer test questions at different rates. In addition, I've found that it s awkward to go back and repeat questions that students missed or passed over to answer later. A final area where the magnification factor comes into play has to do with the instructor s appearance. With so much of the focus on the visual aspects of the class, the way you look becomes more important. The colors and patterns of your clothes matter more on TV than they do in a conventional classroom.
Blues look best over TV, reds worst.
Since distant sites feel remote and isolated as it is, the instructor needs to present a warmer and friendlier approach to the classroom, especially by smiling more than usual. Looking into the camera draws the viewer in more. It is imperative to dress appropriately for all programming, since the instructor must personify credibility and professionalism. Dark suits and simple patterns look best. I always wear a suit jacket and tie.
