suit.Comments from an old curmudgeon:
I think better and faster when writing with white chalk on a black board.
I believe my students learn more from such a presentation.
The age-old mark of a teacher has always been chalk dust on hands and
somepoj
I used to be a chalk diehard and have made all of the above comments at
time. I was weaned by a spell of 5 years in a temporary lab where I had toof acetate. In
write on the OHP. I found this physically convenient as I could face the
class while writing, so it made for better communication.
the new lab I use mainly the whiteboard, and I really don't miss the chalk.layers
The main advantage is that the place is really *much* cleaner without
of calcium carbonate over everything. It's just aesthetically a lot better.
