I’m surprised by the outrage to the teaching style, specifically people taking issue with the expectation that students take questions to office hours. Perhaps many who have studied math have forgotten, but “so and so is left as an exercise to the reader” is basically a trope at this point. I’d even go as far to say that you can’t really learn all the content in a math textbook without talking it over with someone. Math text books aren’t very dense, yet it can take a day or more to fully grasp a few pages. Simply adding more exercises, even with answers, isn’t necessarily going to deepen one’s intuition. Which brings me the specific class this article is about: linear algebra. LA has to been one of the worse taught classes, and that seems to be universal. Things like determinants and Eigen values are drilled in students’ heads without developing the intuition for the subject first. They’re given examples without context, which is what the girl described in the article seems to be struggling with. She probably still would struggle to learn LA even with answers to the examples.
