The Effect of Increasing Class Size on the Grades of Students in the Business Curriculum at Piedmont Technical College.
Morgan, John A., Jr.
Funding constraints had resulted in the need to increase the size of classes conducted by the Business and Technical Division of Piedmont Technical College. In the absence of budget limitations classes were split when enrollments exceeded 30 students. This study was initiated to examine the relationship of class size to course grade point average (GPA) during a two-year period. The 12 courses chosen for the study had both high (over 30) and low (30 or less) students, were conducted by full-time staff, and were of the same level of difficulty. A Z-test at the .05 level of significance was used to test the null hypothesis that there is no significant difference in course GPA's of students in large classes and those in small classes. The Z-value of .2881 was less than 1.96, the area of concern under the normal curve, resulting in an inability to reject the null hypothesis. The difference between the mean GPA's of the large and small class groups was statistically insignificant. The results of this study form the basis for formulating class size policy beginning fall 1978. A review of the literature revealed that findings of studies on class size varied considerably, and that although much research supported small classes, there appeared to be some consistence in the findings that class size had little effect on student performance. A bibliography is included. (Author/MB)
