As enrollment rates in colleges have continued to increase, a new book questions whether the historic number of young people attending college will actually learn all that much once they get to campus. In Academically Adrift: Limited Learning on College Campuses, two authors present a study that followed 2,300 students at 24 universities over the course of four years. The study measured both the amount that students improved in terms of critical thinking and writing skills, in addition to how much they studied and how many papers they wrote for their courses.
Richard Arum, a co-author of the book and a professor of sociology at New York University, tells NPR's Steve Inskeep that the fact that more than a third of students showed no improvement in critical thinking skills after four years at a university was cause for concern.
"Our country today is part of a global economic system, where we no longer have the luxury to put large numbers of kids through college and university and not demand of them that they are developing these higher order skills that are necessary not just for them, but for our society as a whole," Arum says.
There's a huge incentive set up in the system [for] asking students very little, grading them easily, entertaining them, and your course evaluations will be high.
Part of the reason for a decline in critical thinking skills could be a decrease in academic rigor; 35 percent of students reported studying five hours per week or less, and 50 percent said they didn't have a single course that required 20 pages of writing in their previous semester.
According to the study, one possible reason for a decline in academic rigor and, consequentially, in writing and reasoning skills, is that the principal evaluation of faculty performance comes from student evaluations at the end of the semester. Those evaluations, Arum says, tend to coincide with the expected grade that the student thinks he or she will receive from the instructor.
"There's a huge incentive set up in the system [for] asking students very little, grading them easily, entertaining them, and your course evaluations will be high," Arum says.
At every university, however, there are students who defy the trend of a decline in hours spent studying — and who do improve their writing and thinking skills. The study found this to occur more frequently at more selective colleges and universities, where students learn slightly more and have slightly higher academic standards. Overall, though, the study found that there has been a 50 percent decline in the number of hours a student spends studying and preparing for classes from several decades ago.
"If you go out and talk to college freshmen today, they tell you something very interesting," Arum says. "Many of them will say the following: 'I thought college and university was going to be harder than high school, and my gosh, it turned out it's easier.' "
