I always look at the body language because it tells me so much. I can see if my class is restless because they are not interested. I want to know that I am engaging them, from the moment I see unfavorable body language I know that I have lost them then I have to figure out how to get them back on track. Sometimes it is tough because certain aspects of the class require a lecture. So instead of lecturing too much, I get my points across through engaging stories. It's tough sometimes. And usually there is always one person in the class who can throw the entire dynamics of the class into a different direction. At the beginning, I like to identify that person so that I do not lose control of my class. Body language speaks volumes. Fortunately my classroom has mirrors so it allows me to see everything.
