Abstract
This paper reports the results of a quasi-experimental study on the contribution of the Responsive Classroom Approach (RC) to elementary school children’s reading and math performance over one-, two-, and three-year periods. All children enrolled in six schools (3 intervention and 3 control schools in a single district) were the participants in the study. Children’s test scores in math and reading were used as outcomes, and data on treatment fidelity were used to describe differences in use of RC practices between intervention and control schools. Findings showed that, after controlling for poverty and test scores from previous years, the RC Approach contributed to the gains in both reading and math, with math showing greater difference between the intervention and control schools. The contribution of the RC Approach appeared to be greater over a three-year period than over a one or two-year period. These findings provide early evidence for the positive contribution of the RC Approach to gains in academic achievement.
