That’s not going to come as a big surprise. What leaves most of us a bit breathless and depressed are the numbers. The study referenced below cites four other studies in which more than 70 percent of the students reported not doing assigned reading. In this study, done in a genetics course—not a beginning course but one with two prerequisites, presumably a course for science majors—54.4 percent said they did none of the pre-lecture reading and 33.3 percent said they did some of it. The students were asked weekly about their reading and these are the overall percentage amounts.
