Knowledge decay between semesters
"Debate continues on the implications of school scheduling and its impact on student learning and learning loss, specifically over summer breaks. This paper provides the first evidence on learning loss in higher education. Students enroll in a variety of course sequences in college. Using administrative data from Clemson University, we focus on course sequences taken two semesters in a row, either fall–spring or spring–fall. Sequences taken fall–spring offer a shorter gap between courses than do courses taken spring–fall."
