In the course of the year, I found that even being wired to my projector through the VGA cable was too confining. I wanted to be able to wander the room with my tablet as I ran through my demo’s, lectures, and whatever. I also wanted to be able to plop my tablet down in front of a student so they could do examples or show their insights “on the fly.” It also has the benefit of letting me work through some ideas of how I would teach a class if everyone had a tablet. Since I had been very frugal with my funds for the past several years (and my students had gone easy on the science glassware), my principal gave me the funds to buy a new projector that supports wireless connectivity (an Epson 755c). Of course, I think he was really going to get another projector anyway and that he like the one I had just fine ;-)
It just arrived and I’m going to start testing it out as this week – I’ll let you know how it goes!
