Advice for the creative writer, yes. But the student? My manager is taking a summer class and his teacher told the class, "Don't write down what I say. Write down what you feel about what I say." Interesting advice for a note-taker who's thinking about regurgitating the content for the next test. My reporting background feeds into my natural tendencies to observe and notate, to somehow duplicate what I'm reading or listening to in class; it's distancing. Paraphrasing what the teacher says during a lecture is a good idea, but the cognitive load of paraphrasing something said a minute ago in my own words as new content is also streaming in is too much for me.
But I like the idea of recording my reactions in class, even if they're baffled. It's fast, it's in the moment, it hooks me. Engage me on the emotional level, and I'm halfway there. That said, I can see this strategy applying more to issues-oriented topics than information retrieval algorithms. But it's a new tool I definitely want to try out this fall.
