Chalk: cheap and simple, it always works
Dry-erase markers: get with the program, guys.
PowerPoint: Move into the 21st Century
Cold chisel & mallet: permanence
One place that I worked at had a room where the entire walls were whiteboard. You could scrawl a whole lot of stuff on there.
But some of it was years old and hadn't been erased, jokes and skedtches and other creative stuff. I presumed it was important, and I never made use of those walls.
I saw someone use a system named Prezi yesterday. Web-based, intuitive and much flashier than powerpoint. Might check it out.
Jokergirl, I like what I've seen with Prezi. Unfortunately, I haven't had the time to check it out myself so I can't say much more about it.
Powerpoint can be evil in the wrong hands.
I had an excellent teacher who used power point presentations for every class complete with instructions to print it with lines next to each slide. The slide was the heading basically with a little bit of detail, the rest was all on us to write down. Her lecture style was very interactive, so it worked well.
I have seen others throw notes into a slide then read them at you at high speed. Perhaps they mix up slides to change it up from class to class. That stinks because they usually don't give you a copy of the presentation.

I like a combination of both Dry erase markers and whiteboard. The former for lecturing and the latter for doing example problems.
Even back in the 1970s, when I was a student, I had some professors who'd cancel a class if their overhead projector failed and they couldn't get a replacement. They couldn't stand writing directly on a board of any kind. Since then, I've been on the other side, and indeed it is more tiring writing full-sized script for an hour. (Yeah, I know that there are more strenuous jobs out there.)
One of the unspoken advantages of writing on a projected transparency rather than a wall board is that you don't have to turn your back on the class, something that junior high school teachers must never do.
recycled from a post made five years ago about powerpoint presentations:
"This reminds me of a class I took in first year. The podium had an overhead projector on either side of it, and all year long the prof used the one on his right. Then one day, as he was sketching something or other on the projector, there was a bright flash and bang from it, and out went the light. He calmly flipped on the other projector, put the pen in his left hand, and continued on with sketching and talking, as if nothing had happened. I could barely perceive a difference in his penmanship. I think about 150 jaws dropped at once."
Chalk has several advantages.
One, you know when you pick up a piece of chalk whether it is good to write with. Not so with a dry or wet erase.
Two, unlike Powerpoint, it works when the tech doesn't and in more lighting conditions.
Three, unlike dry or wet erase, it does not stain if left too long on the board, but comes off with a wipe of the brush.
Four, It doesn't require sanding or a grinder to erase like the hammer and chisel.
It's one downside is it is fairly fragile, but if left alone, it will still be legible for as long as likely needed.
Fifth, nothing says "professor" like chalk dust all over a dark, tweed jacket.

All moderation in purple - The rules
To express myself electronique,
I often times must critique
The high tech method should I balk,
Thank God I still have trusty chalk !
Would admin mind if I created a sock puppet account to vote for powerpoint? I feel sorry for it having zero votes? Not!
