The purpose of this study was to determine the effect of the discovery learning model on mastery of high school physics concepts and knowledge. The method used in this research is meta-analysis. The data analysis technique in this study uses the calculation of the effect size value for each article. Based on the meta-analysis carried out, it can be stated that the results of this study are: 1) the effect of the discovery learning model on mastery of concepts and knowledge of high school physics in terms of the year the article was published gave a Very High effect in 2017,2018, and 2020 with each the average effect size is 1.6; 1.15; and 1.62. 2) the influence of the discovery learning model on the mastery of concepts and knowledge of high school physics in terms of grade level gives a very high effect in class XI with an average effect size of 1.25. 3) the effect of discovery learning on mastery of high school physics concepts gives a Very High effect found in the sixth article (J6) with an effect size value of 2.38. 4) the effect of discovery learning on high school physics knowledge gives a very high effect in the tenth article (J10) with an effect size value of 3.95. This shows that there is an influence of the discovery learning model on the mastery of high school physics concepts and knowledge.
