(19)Most American college students are wrapping up another semester this week. For many of them, and their families, the past months or years in school have likely involved considerable time, commitment, effort and expense. Was it worth it? Some evidence suggests that it was. A Pew Research survey this year found that 74% of graduates from four-year colleges say that their education was "very useful in helping them grow intellectually"(20)and 55% claimed that "it was very useful in helping prepare them for a job or career." Moreover, 86% of these graduates think "college has been a good investment for them personally. "Nonetheless, there is talk about the "failure" of higher education. Much of this has to do with access: It’s too expensive; admissions policies are unfair: the drop-out rate is too high. In particular, the university curriculum leaves students disengaged from the material they are supposed to be learning.(21)They see most of their courses as intrinsically "boring," of value only if they provide training relevant to future employment or if the teacher has a pleasing way of presenting the material. As a result, students spend only as much time as they need to get what they see as acceptable grades. This lack of academic engagement is real, even among schools with the best students and the best teachers, and it increases dramatically as the quality of the school decreases.(22)But it results from a basic misunderstanding—by both students and teachers—of what colleges are for.
