Concepts occur as a result of the classification of objects, things, events, situations etc. in our environment according to their characteristics and their relationships with each other. We frequently encounter to the concepts in mathematics lessons, as in all areas of our lives. Since the concepts encountered in mathematics lessons are abstract in nature, students may have difficulties in these concepts. Understanding the meaning of the concepts in a way that differs from the original in individuals creates misconceptions. Misconceptions negatively affect learning. The aim of this study is to examine the graduate studies about the misconceptions experienced by primary school students in mathematics lessons within certain categories and to determine their general tendencies. For this aim, 81 theses, addressing the purpose of the research, which are reached from the database of the Yükseköğretim Kurulu Ulusal Tez Merkezi between 2005-2020 in Turkey; the aim of the thesis, the research model used in the theses, data collection tool and data analysis method were examined according to its categories. As a result of the examination, it was observed that theses were mostly aimed at determining misconceptions, studies in quantitative research model were more, success tests were the most preferred data collection tool, and quantitative data analysis methods were used more.
