The AI course finished this week. Here is a link to a discussion thread involving some very mathematically able people discussing, after the exam results were in, a "disputed" mark concerning an exam question about a statistical technique called Laplace smoothing.
I'm not making a point about the substance of the discussion (a lot of which is over my head), or about the underlying investigation (which is even more so).
But the interesting thing is the way that this open course, with its underlying conventional, assessed structure, has resulted in a great deal of very high level collaborative research, investigation, and discussion, which has gone far beyond its (first year US undergraduate) boundaries.
Even if the subject matter of the post is outside your ken, it is worth taking in the kinds of reflections that contributors are making, for example:
"This is really the sort of thing and the sort of thinking and exploring that I believe professors really want to see result from efforts to teach stuff in class (whether in K-12 or undergraduate or graduate school). This one little question has generated more serious inquiry than anything else I have seen so far from our class...... But THANK YOU for all of the serious and thoughtful responses to this question which it has been a pleasure to read."
