This study attempted to comprehensively examine the results of experimental studies which examined the effects of Task-Based Language Teaching (hereafter, TBLT) conducted in Korea through meta-analysis. To this end, TBLT- related studies were searched for and collected through an academic database, and meta-analysis was implemented on 75 research cases included in 21 studies. The results are as follows. First, the mean effect size of TBLT used for English teaching was .569, which is slightly higher than the medium effect size. Second, mean effect sizes calculated according to two moderators (school level and treatment period) were between the medium effect size and the large effect size, and no statistically significant differences were found between each effect size. Third, the mean effect sizes calculated by dividing the dependent variable into language ability and the affective domain were .538 and .587, respectively, slightly exceeding the medium effect size, and there was no statistically significant difference between the two variables. Based on the findings, suggestions for further research were discussed.
