This study was conducted with the aim of comparative investigation of master theses that were written in the field of Mathematics Education between the years of 2010-2017 in terms of the variables such as university, year, gender, language, research type, research model, sub-learning fields, data collection instruments, sampling and the statistical techniques that were applied. 490 postgraduate theses and 112 doctoral theses, total of 602 postgraduate theses, which were found in the database of Institute of Higher Education and accessible with the detailed search of department of primary science and mathematics education, department of primary education mathematics education, department of mathematics education, department of primary education mathematics teaching and department of primary education, constitute the sample of the research. As the study was a meta- analytic examination of the conducted thesis, it was basically a qualitative study in the descriptive model. The evaluation form which was developed by the researcher was used for examining the thesis. The results of the study point out that there are more female researchers in recent years; while the students are used as the sample of the study in the master thesis, both the students and the pre-service teachers are used in the PhD thesis. Geometry and Assessment are the sub fields that are conducted most while the studies in the data processing are seen to be very few. Besides, the increase in the mix research in educational research in the recent years is also observed in the context of the study.
