A study was conducted to determine the effect of limiting class size in developmental English on subsequent student performance in a college-level English course. Class size effects were studied for two groups of students enrolled in College English I at the seven two-year branch campuses of Kent State University (i.e., Ashtabula, East Liverpool, Geauga, Salem, Stark, Trumbull, and Tuscarawas). The first group had completed "Introduction to College English" (a developmental course) in fall 1989, when class size was not limited and classes averaged 17.1 students. The second group completed the same developmental course in fall 1990 when class size was limited to 15 students, and classes averaged 12.3 students. Analysis of Variance (ANOVA) and Chi Square procedures employed to compare the academic records of students in the two groups. Study results included the following: (1) students who completed developmental English when class size was limited had higher average grades in college-level English than the students who were enrolled in the larger classes; (2) students at Ashtabula, East Liverpool, Geauga, Salem, Stark, and Trumbull campuses, who were enrolled in the smaller developmental course had statistically higher percentages of better grades; (3) there were no significant differences in students' grades at the Tuscarawas campus; and (4) college-level English course withdrawal rates were the same for both groups of students. ANOVA and Chi Square tables with results for each of the seven campuses are included. (PAA)
