Findings read from the forest plot of the 31 included studies, where standardized mean differences with 95% confidence intervals were "in favor of the posttest group".

Distribution of the 31 studies' effect sizes by Cohen's classification and direction, as reported alongside the forest plot (Figure 1) of the meta-analysis.

"Classifying these studies in regard to Cohen’s (1988) effect size classification, the effect size was found to be “large” in 17 studies, “moderate” in 6 studies, “low” in 4 studies, and “no effect” in 4 studies. 28 studies’ effect sizes are in favor of posttest, whereas there are only 3 studies favoring pretest."
