Problem Statement: Self-regulated learning strategies (cognitive, metacognitive, resource management, and motivational strategies) influence students’ academic achievement, conceptual understanding, and motivation. Reviewing the national literature about self-regulated learning strategies, studies have indicated both significant and insignificant effects on academic achievement; however, no meta-analysis studies have been carried out. Purpose of Study: The aim of this study is to calculate the common effect size of empirical and relational studies conducted in Turkey between 2005-2014 that investigated the effect of (or relationship with) self-regulated learning strategies on academic achievement, and to determine whether the common effect size shows a significant difference in terms of course type, self-regulated learning strategy type, school level, and study design. Method: A meta-analytical review method was employed to combine the outcome of independent empirical or relational studies. The studies included in this review were collected from the CoHE National Thesis Archive, ULAKBIM, Google Academic, ERIC, and EBSCO databases. A total of 47 studies were assessed in accordance with the inclusion criteria, and 21 studies were included in this study. Cohen’s d coefficient was calculated for the effect size in this study. Findings and Results: As the heterogeneity among the effect sizes of the studies was high (Q > χ2, p < .05), the common effect size was calculated in accordance with the random effects model. As a result of the meta-analysis, it was determined that self-regulated learning strategies had a “large” effect (d = 0.859) on academic achievement. Moreover, the calculated common effect size showed no significant difference according to the type of self-regulated learning strategy, course type, study design, and school level. Recommendation: As self-regulated learning strategies exhibit a substantial effect on students’ academic achievement, it is recommended that preservice and in-service teachers should learn how to implement these strategies in their lessons to increase their students’ performance. For this purpose, professional development programs should be designed for teachers
