Pretty simple; which do you prefer? I'm a whiteboard person. I just hate getting all that powder everywhere.

today I am a total "smart-board" convert. I use a Promethean board with an LCD projector. The board is my computer desktop, my pen is a mouse. Everything I write on the board is savable. I teach two classes of Honors Physics, and I can toggle back and forth between what I did in the previous class to what I am doing now. So if something went particularly well in the first class, I can repeat it almost exactly.
Furthermore, I can put up Java applets on the board to show animated examples of things. Totally cool, and I'm only up to about 20% of what this thing is capable of.
No dust, no fumes, no black grit, no cleaning.
I just keep losing my Promethean pen.
Not true, unless you buy quality whiteboard.MotoH said:Much easier to erase
Same thing, if you buy quality blackboard, no scratch will appear. I've seen century old blackboards. If you're going for the cheap stuff, the question is not relevant, as whatever you choose will be bad anyway. If you're going for the expensive stuff, you will later save money on chalk compared to markers (that's a big difference by the way). Besides, there is no chance of having someone use a permanent marker on a blackboard.MotoH said:Plus there is no chance of having that retched chalkboard scratch with a whiteboard!

Seriously though : if you are going to use the board moderately, a whiteboard is better. But for intensive use, like several square meters per hour, day long, then markers do become expensive, and the cleaning and dust created do become more inconvenient than chalk.
What about using large sketchpads?George Jones said:Chalkboard!
I have taught using a chalkboard; I have taught using a whiteboard; I have had a chalkboard in my office; I have had a whiteboard in my office.
For example, I first did the short calculation

using my chalkboard, not pen/pencil and paper.

ps - anyone tried to build this ? http://johnnylee.net/projects/wii/
