College students study a lot less now than in the 1960s, yet they get better grades.
For students, these trends must seem like marvelous developments. But they raise questions about both declining rigor and potential grade inflation in higher education.
In a forthcoming study in the journal Economic Inquiry, economist Philip Babcock finds the trends linked. As Babcock related in an e-mail, when the instructor "chooses to grade more strictly, students put in a lot more effort." And when the professor gives easy A's, students expend less effort.
The finding relates to an earlier study, cited in a previous post here, showing that professors who get high ratings from their students tend to teach those students less. (The minimal effort required in those classes apparently fuels the professor's popularity.)
Babcock, an economist at the University of California, Santa Barbara, reviewed two sets of research literature that document crisscrossing trends.
