Abstract :Predict-observe-explain (POE) is a strategy that has been used in science education for several decades. It is important to determine how effective this strategy is, especially when used in the constructing scientific concepts. In this study, the effect of the POE strategy on students’ science achievement was examined in a meta-analysis. Databases were searched using specific keywords and 35 studies (6 theses and 29 articles) that met the inclusion criteria were found. Hedges’ g and the random effects model were used to calculate effect sizes. As a result, the average effect size (g=0.979, 95% CI: 0.771-1.188, p<0.001) was found to be high. The POE strategy was found to increase students’ science achievement with a high-level effect. The differences between studies were determined by analog to the ANOVA and meta-regression moderator analyses. While the effect of POE on students’ science achievement differed significantly according to the moderators of field of science and level of education, it did not differ significantly according to the moderator of implementation type. The moderators of implementation time and year of publication were similarly not found to be significant predictors of the effect of POE on science achievement. Based on these results, suggestions are made for researchers and practitioners.
