The purpose of the study is to synthesize the studies of the relationship between achievement
goal orientation and self-regulated learning by meta-analysis. The research questions were to
know the total effect size between achievement goal orientation and SRL and to know the
difference of the effect sizes between school classes. To achieve research questions, researchers
searched for a variety of databases and analyzed 51 studies, which were 23 master's theses, 4
dissertations, and 24 journals from 1991 to 2013 in Korea. Achievement goal orientation was
divided by mastery approach, mastery avoidance, performance approach, and performance
avoidance goal orientation. Self-regulated learning was divided by cognitive, meta-cognitive,
motivational, behavioral regulation. Publication biases were analyzed by Rosenthal & Orwin's
Fail-safe N, Egger's intercept, and Duval & Tweedie's trim and fill method. In the analysis, there
were publication biases in the variables so the research included imputed effect sizes by trim and
fill method to interpret the total effect size carefully. In the analysis of the effect size, mastery
approach goal orientation-SRL was .433(imputed ES=.322), performance approach goal
orientation-SRL was .257(imputed ES=.188), mastery avoidance goal orientation-SRL was
-.016(imputed ES=-.266), and performance avoidance goal orientation-SRL was .005(imputed
ES=-.023). There were heterogeneities in the total effect sizes of the variables, so the researchers
thought these were attributed by school classes. In the analysis of effect size by school classes,
university was the highest and high school was the lowest in mastery-, performance approach
goal orientation and SRL. In mastery-, performance avoidance goal orientation and SRL
university was the highest and elementary school was the lowest. Based on the relevance of prior
researches, the significances and implications of the study were discussed.
