The Longitudinal Effects of Smaller Classes: Four Studies.
Gilman, David; Tillitski, Christopher
Four studies were conducted to ascertain the long term effects of reducing class size in primary grades. Study One compared the effect of class size reduction on one school system when all students' scores were compared. Study Two was a repeated measures cohort study in which the scores of 193 students who had attended reduced size classes in the same school district for 3 years were compared to those of a similar number of students who had attended larger classes. Study Three examined the effect size of reduction in student/teacher ratio in 27 school districts in Southwestern Indiana. Study Four examined the effect of smaller classes on a statewide basis by comparing the mean scores on the state competency test. The clear and consistent indications of these comparisons of reduced size and regular size classes suggest that the long term effects of a state-sponsored class size program are negligible. It is concluded that, although this study and others have found no educational benefits for reduced size classes that can be translated to gains in achievement test scores, the Indiana experience does not necessarily imply that all state class size reduction programs are doomed to fail. Hastily implemented, PRIME TIME was not a well-conceived class size reduction program. Unless class size reductions are planned, teachers are trained, and programs are evaluated, smaller classes will very likely be a very inefficient and costly reform that will have little effect on student learning.
