I am not sure this is all that surprising:
Many of the students graduated without knowing how to sift fact from opinion, make a clear written argument or objectively review conflicting reports of a situation or event, according to New York University sociologist Richard Arum, lead author of the study. The students, for example, couldn’t determine the cause of an increase in neighborhood crime or how best to respond without being swayed by emotional testimony and political spin.
And then there’s this:
Forty-five percent of students made no significant improvement in their critical thinking, reasoning or writing skills during the first two years of college, according to the study. After four years, 36 percent showed no significant gains in these so-called “higher order” thinking skills.
Combining the hours spent studying and in class, students devoted less than a fifth of their time each week to academic pursuits. By contrast, students spent 51 percent of their time — or 85 hours a week — socializing or in extracurricular activities.
The study also showed that students who studied alone made more significant gains in learning than those who studied in groups.
