though,I have not taken this course, but the blog did did bring up some very interesting ways to engage students,I usually keep a soft ball in class, and as soon as I see that the lecture is somewhat becoming boring, I change my venue,,and we start a game of throw ball, who ever has caught the ball will answer a question to the recent topic of our discussion/lecture.this keeps the students on alert,if a student answers correctly, there is a small reward, a candy or chocolate.
