Increasingly, our classrooms are set up with a white board across the front of the room, and in front of that, in, say, the position of an altar, is a large "teaching station" set up so that someone can stand and look at a computer monitor. The computer, a nearby document camera, or other media thingy can be projected onto a big screen. About half of the screens are fixed in place, and about half can be pulled down or rolled up.
Sounds great, but when you sit down in the room, you realize that from any seated position (much lower than the "station"), the "teaching station" effectively blocks about one third of the board. It blocks a different third for some students than others, making about 2/3rds of the board space pretty ineffective.
And, of course, the "teaching stations" are tethered in place at the bottom by an umbilical cord of electronic connection things, so they can't be moved much more than two feet in any direction.
Ugh. Bad planning.
I write on the board a lot. Mostly, what I write is prompted by student questions, so I'm trying to respond at a given moment to a question with an illustrative bit of verse, a drawing, words, whatever. If I could see into the future, I could probably prepare powerpoints, but since I really try to make class responsive to student questions and issues, I'd have to make a ton of powerpoints and then sift through them, and hope I'd pre-prepared for every possible student question about every possible thing. But I can't see into the future, so I don't.
I've taken to using the document cam, but now I have to remember to take un-lined paper in and a thicker pen, because otherwise it's pretty unreadable.
I don't know how else to solve things, but planning for a less obtrusive "teaching station" and more board space would make me happier, for sure.
