In Kiewra (1987), 91% of students recorded in their notes the main points of a lecture, but not as many students recorded subordinate points (60% for secondary points, 35% for tertiary points) and very few students (11%) recorded the most-specific details of a lecture. The accuracy of “level 1″ and “level 4″ points recorded in students’ notes wasn’t predictive of their short-term or long-term test performance, in part because so many and so few students, respectively, recorded those points, but “level 2″ and “level 3″ accuracy were predictive of student performance.
