Hi Mark, Good point. I to teach in a multi-level system and sometimes just getting a classroom that is appropriate is difficult. Due to a central office mistake,this phase I am teaching in the break room, where students and faculty come to warm up their food in the microwave. I only have a overhead projector as my media. I haven't used one of these for years. I can assure you that it will not happen again because my students have paid a lot of money to receive an education and they should have the very best. A side note is that I have a great bunch of students that are working very hard in the course in spite of all the challenges or maybe because of them and they are very happy with the content they are receiving.
