Abstract
This study estimated the impact of class size on instructional practices and the use of time in high school mathematics and science courses. More specifically, the analysis examined the influence of class size on two categories of variables that measure the use of time: (a) time devoted to instruction (e.g., working with small groups, using innovative instructional practices, leading whole-group discussion, amount of homework assigned) and (b) time committed to noninstructional activities (e.g., conducting administrative tasks, maintaining order). The analysis also explored the influence of other factors such as characteristics of the class and the teacher. Findings revealed that class size has an impact on the use of class time, both instructional and noninstructional. The effect varied by subject area, type of student, and amount of time teachers spend planning for class.
