I teach physical therapy. I tell my students that they can learn a lot from looking at someone's eyes. We can see fear, pain, happiness, along with many other emotions. The same goes for students. YOu just have to look. But here is my concern. As an instructor, I hate looking in people's eyes. I am a very strong introvert and by looking into the student's eyes, I have to use a lot of energy. However, I can and will do it if necessary, especially when I need to get my point accross. There are many people who are like me. When I was in grad school, we were discussing stereotypes and someone mentioned that people who don't look at you in the eye is mischevious and not trustworthy. I was really offended by that. But introverts are not the only ones who have problems looking one in the eye. What about various cultures who feel you are being disrespectful if you look your superiors in the eye? What about the person who is abused, both mentally, physically or verbally? They don't want to look you in the eye as well. When we look at our student, yes, we will get a lot from their eyes, but look deeper than that, and it will tell you more than you could imagine!
