Why is the overall quality of undergraduate learning so poor?

While some colleges are starved for resources, for many others it’s not for lack of money. Even at those colleges where for the past several decades tuition has far outpaced the rate of inflation, students are taught by fewer full-time tenured faculty members while being looked after by a greatly expanded number of counselors who serve an array of social and personal needs. At the same time, many schools are investing in deluxe dormitory rooms, elaborate student centers and expensive gyms. Simply put: academic investments are a lower priority.

The situation reflects a larger cultural change in the relationship between students and colleges. The authority of educators has diminished, and students are increasingly thought of, by themselves and their colleges, as “clients” or “consumers.” When 18-year-olds are emboldened to see themselves in this manner, many look for ways to attain an educational credential effortlessly and comfortably. And they are catered to accordingly. The customer is always right.

Federal legislation has facilitated this shift. The funds from Pell Grants and subsidized loans, by being assigned to students to spend on academic institutions they have chosen rather than being packaged as institutional grants for colleges to dispense, have empowered students — for good but also for ill. And expanded privacy protections have created obstacles for colleges in providing information on student performance to parents, undercutting a traditional check on student lassitude.

Fortunately, there are some relatively simple, practical steps that colleges and universities could take to address the problem. Too many institutions, for instance, rely primarily on student course evaluations to assess teaching. This creates perverse incentives for professors to demand little and give out good grades. (Indeed, the 36 percent of students in our study who reported spending five or fewer hours per week studying alone still had an average G.P.A. of 3.16.) On those commendable occasions when professors and academic departments do maintain rigor, they risk declines in student enrollments. And since resources are typically distributed based on enrollments, rigorous classes are likely to be canceled and rigorous programs shrunk. Distributing resources and rewards based on student learning instead of student satisfaction would help stop this race to the bottom.
