@7xMichael - I pass by all sorts of classrooms on the way to my office - mostly future teachers education classrooms and mathematics - one classroom usually has an older professor - I rarely see him standing at the chalk board (most classrooms now a days are "smart boards" - interactive chalkboard things - but he is usually sitting. Students are watching a video of a math procedure. Ha - I never had that one before - good thing too as I would have been asleep. Math classes I had to be alert - never knew when they would pick on me for the answer to that part of the problem... huh? hehe
