I will be moving to a small school in the fall. They don't have doc cams or elmos, but would be willing to buy if there is a need. The principal showed me the classrooms and they have huge floor to ceiling windows in them. I don't think a doc cam or an elmo will work in these rooms due to so much light. Will I have to do without? And if I do, how do I teach without? Have you tried, once you got used to the technology?
