I have found this coarse very interesting. I didn't realize that when i asked my students "is there any questions", that I was putting them on the spot. I have changed my tactics. The way my students are paticapating has already changed. I ask a lot of closed questions, then make them open questions by asking why, how, etc. I am now making up different tests to include more and better open ouestions . For example: Explain how a canned cycle works and why we use them instead of direct programing? It lets me know if the student really understands the concept. I can't wait for my next class to start so I can apply my new approach to asking questions.
