Professor Arum and Professor Roksa make some excellent points in their NYTIMES op-ed:
"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."
"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."
