It's funny that the one speaker cited Michigan as having a "flunk-out" system to weed out lesser techies. I didn't see that at all there.
Students who got in largely stuck with the program. The Engineering School even had every test open-book, so there was nothing to
memorize. That didn't necessarily make it easier, but if you did the work & learned the material, you stayed. But we had & have a
lot of ferrin students & teachers. That was a good thing...as long as ferrin instructors spoke English.
I agree that our educational system is highly flawed. We need to get more kids excited about math and science if we want to be able to exist as a country, or at least a first-world nation, in the future.
I actually know someone here in Ohio who's college does that weeding out thing with their science students. Not too smart. At least the way that they do it.
