Chalk dust is a thing of the past, as are dry erase markers. Today, I’m more likely to be frustrated with some technological glitch rather than dry skin from chalk dusk or headaches from whiteboard cleaner. The advantages, of course, vastly outweigh the disadvantages.
Of all the high, sophisticated advantages, there are some more simple, basic boosts to productivity.
For example, I can save every single thing we put on the board. Which I’m sure can be somewhat overwhelming to some students.
