I would like to just make a small note. I love questions and answer sessions in class. I use many of the tech. talked about in this lesson. I just wanted to mention that I never stop with questions and answers. All my studets know anytime my office door is open they can have a question and answer session with me. I am willing to put aside what ever I'm working on to help the student. If I can not offer my time then I just shut my door. My door is open about 99.9% of my day to students. The point I'm trying to make is that I think teachers should be accessible to students as much as they can be.
