Colleges and universities offer classes that meet for different lengths of time and different numbers of days per week, such as classes that meet 2 days and those that meet 3 days. Traditionally triweekly classes that met for a shorter duration were more common than classes that met biweekly for a longer duration. Biweekly classes are becoming more popular with time. However, there is some concern that classes that meet more often are better suited for student learning than others. This paper, using data from a small liberal arts college, finds that after controlling for the starting time of the class meeting and course fixed effects as well as faculty and student fixed effects, student learning across 2 and 3 days classes is essentially the same.
