The aim of this research is to determine the trends of academic articles and postgraduate theses that employ the meta-analysis method in the field of mathematics education and that were published in Turkey between 2011 and 2020. Using the qualitative research method, this research aims to examine with descriptive content analysis the studies carried out in the field of mathematics education by using the meta-analysis approach. The data of this research consists of academic articles and postgraduate theses prepared using the meta-analysis approach in the field of mathematics education at the national level between 2011 and 2020. The data collection tool of the research is the "Publication classification form", which was prepared by the researcher. The data of the research were analyzed by descriptive content analysis. The reliability of the research was determined by the consensus formula of Miles and Huberman (1994). The studies examined in the research are classified according to years, study type, independent variable, dependent variable, effect sizes, and effect directions. For the findings of the research, frequency and percentage tables of the studies examined were created. In the findings of the research; It was concluded that the studies were carried out mostly in 2019, academic articles and theses were mostly examined together in the studies, the Computer-Aided Mathematics Teaching method was the most frequently investigated subject through the meta-analysis, academic success was investigated as the dependent variable, and the effect sizes of the studies were moderate and their directions were mainly positive. It is recommended to conduct a meta-analysis of recently used distance education methods and of the new constructivist approaches.
