I have to ask. Why is it "white"-board vs. "chalk"-board? Back in elementary school, I learned to call the former "black"-board.

In the UK they still call them "blackboards", I've never seen a green one over here.

Yup, as an Aussie my understanding is that UK English would call it a blackboard whereas US English would call it a chalkboard. AU English therefore followed the UK, regardless of if they're the dark angels-esque green or fully black colour.

Ronald Susskind uses a white board and calls it a black board

Ronald!? Leonard... now I can't edit it and forever I will look like an idiot.

Not an explantion, but I do remember when they first arrived (there was one the year I began high school -- new physics teacher got to set it up how he wanted) and no new ones when I left. I also saw then appear at MIT, again, mainly new construction/renovation. Chalk boards came in black or green. That name is lost in history, to me. Whiteboards were kind of a shock by comparison -- bright rather than dark -- so it…

"dry erase" means the ink comes off even when dry, as opposed to a permanent marker.

Also, after a long time, even dry erase needs toothpaste to come off.

Chalk boards are very visceral, Bringing a chalkboard instead of powerpoint when giving a presentation, makes for a much better presentation, A whiteboard is almost as good but does not have the same impact as a chalkboard.

One big part is that writing speed gives a natural limit of how fast the material can be presented.

With PowerPoint it’s easy to lose the audience, especially in math heavy stuff where taking notes really helps with understanding.

If the presentation is in PowerPoint, there is no way I can keep up.

I still find blackboard + chalk to be a heinous combination. Is this just because my grade school used cheap low-grade chalk? I do have a weird physiological reaction to 'fffffffff' friction sounds. A hard cheap pencil against cheap paper, making a similar raspy sound as chalk-on-blackboard, with cause me to reflexively (and uncontrollably) suck my lips in tight, as if protecting my teeth from the vibrations. Back in…

>Is this just because my grade school used cheap low-grade chalk? Most likely yeah. I remember reading here about the fairytale that is Japanese chalk and that US professors were hoarding it. I assume it must feel orgasmic. We didn't have that kind of opulence in Eastern Europe. Chalk and blackboards here sucked ass, including the cleanup process students were responsible for. Schools switched to whiteboards and mark…

While it's not manufactured by the same company anymore, a Korean company bought the formula and sells it on Amazon now! [0] So, you, too, can see what the hype is all about, if you want! At $0.39 per piece of chalk, it is, indeed, expensive. But, it is also a much different experience from writing with ordinary chalk.

Hypersensitivity to the word "black".

Comments about "chalkboard" being more accurate should only be accepted if the proponent also uses "penboard".
