Ok, 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.
