Watch video lectures from MIT, they know what's up. 9 blackboards sliding on vertical rails. The lecturer doesn't have to waste time erasing boards, and the history stays up for a long time in case students fall behind on their notes.
- ptaipale 11y agoUmm, wasn't something like this a standard thing already long ago? I gave the exercise lessons for programming courses at TKK (now Aalto University) over 25 years ago, and in the bigger lecture halls, we had a system where there were four or five blackboards rotating up/down with an electric control. So you'd fill one blackboard, and then push a button, and the used up blackboard would lift up, remain visible, and you'd go on with the next blackboard. The system looked like it had been in use since the 1960's when the campus was built.

- tfgg 11y agoYou know what? Those lectures were the ones I remember 10x better than the ones with printed handouts and powerpoint slides.
- mavhc 11y agoWell, the Gutenberg Method of teaching suggests that instead of just reading handouts in the lecture you read them beforehand and do the problem solving in the lecture time, when you have the experts available to help when you find out you actually don't understand. http://entropysite.oxy.edu/morrison.html http://entropysite.oxy.edu/morrison.html
- tfgg 11y agoOk, but I'd tend to call those "classes" or "supervisions"/"tutorials" if in small groups. That essay seems to focus on how copying from the blackboard can go wrong, without covering the experience since 1986 of how powerpoint and handouts go even more wrong. This isn't to say I totally disagree. I didn't bother with many lectures in undergrad, and most of my learning happened in classes/supervisions, which I guess are equivalent to what that guy calls the "Gutenberg method". It's just that I found when the lecture was copying from a blackboard, it tended to be worthwhile going - especially since it forces a slower pace and forces you to read the material exactly.
- fusername 11y agobecause writing in those classes dragged you down so much for the rest of the day you didn't read the slides again!
- fnordfnordfnord 11y agoTranscribing the notes is much better than simply having a copy printed for you.
- gone35 11y agoWow: is this factually accurate? Hence the term 'lecturer'? From[1]: "You wonder how on earth such a system ever arose because you know very well that nobody in his right mind would invent a system like this today. What I've heard, and I imagine that this is correct, is that it started a very long time ago, when books were rare and very expensive, and the only way to transmit information was for the teacher, who knew, to tell the students, who did not yet know. And they would write it all down and take it away with them, like a bunch of scribes. Remember, scribes were very big in the Middle Ages."
