The Socratic method is used extensively in medical training to the point that I think most doctors wouldn’t think of it as the Socratic method but rather just as the way you speak to students and trainees.
I can’t imagine how it could work in a lecture hall, it’s best used one on one or at most small groups.
Unfortunately a lot of sites have ditched support for RSS over the past 10 years requiring tedious work arounds if you can get it to work at all.
I hope it can make a comeback but I’m dubious.
