Abstract
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.
Notes
There are various types of block scheduling, but each type is based on having longer classes less frequently.
Hughes (2004) compares the grade point average of students from a large high school in Spartanburg, South Carolina that has transitioned completely from a tradition schedule to a block schedule and finds a positive relationship between block scheduling and student achievement. Zepeda and Mayers (2006) analyzed 58 studies on the effect of block scheduling in high school and found a positive effect on student grade point average and the school climate across all these studies.
Lewis and Cobb (2003) found that student outperform students in tradition scheduling regardless of the type of block scheduling. Edwards (1995) found that most teachers reported significant improvement in their teaching effectiveness after the first semester under the block scheduling. Student achievement also improvement under block scheduling. (Cobb et al. 1999) found mixed, but generally positive results under block scheduling. Students under block system have a higher semester and cumulative grade point average. Male students do even better than female students under the block semester, even though both genders show improvement. Khazzaka (1997) found that block scheduling improved student grades, attendance, and discipline.
While longer class periods encourage teachers to use a variety of instructional methods and more individualized instruction, students perform less well on the tenth-grade mathematics exams under block scheduling, after controlling for the effects of other variables.
Note that the mean reported here is calculated at the student observation level and therefore places larger weights on large class sizes. If the mean was calculated at the course section level, the average class size would be significantly smaller.
