One of today's Chronicle of Higher Ed articles says recent research shows the students do well to read, then practice recall of what they just read as a retention strategy. While faculty may recommend careful reading, they were not stressing this particular step.
The studies support the old SQ4R study strategies--"Survey, Question, Read, Recite, Write, Review."
Many institutions had materials for this method listed on the web: One college's materials (I stopped counting at 30 instutions though there were many more.)So beyond the research points, another key point is that faculty also promote effective study skills for specific courses, perhaps.
