Physics education is one of the basic disciplines that enable individuals to make sense of natural events. With the advancement of science, the research areas and teaching methods of physics education are also undergoing transformation. The purpose of establishing universities is to produce knowledge, to present and teach the produced knowledge to individuals, and to disseminate that knowledge by individuals who learn it. Individuals who receive postgraduate education make scientific contributions to the literature with the theses they prepare. The development of a particular field is most clearly revealed by the works written in that field and postgraduate theses. The development of academic disciplines is realized through academic studies conducted in those fields. It is quite common to conduct content analysis of studies related to that field in order to reveal developments in any field. These studies reveal current studies in the field, developments in the field, and study trends. These content analysis studies conducted in certain fields will be pioneering and guiding for future studies in that field.

In this context, the research conducted aims to reveal the development of physics education by conducting a systematic analysis of postgraduate studies completed in the field of physics education in Turkey. In this context, the postgraduate theses obtained from the Council of Higher Education National Thesis Center (YÖKTEZ) were examined according to their subjects, fields, universities where they were prepared, type, years, language used, sample type, sample size, research method, data collection tools and data analysis type.

A comprehensive document analysis was carried out using a thesis review form developed based on existing literature. The findings indicate that the majority of the postgraduate theses examined were written in Turkish and were predominantly master's level studies. It was observed that certain universities stood out in terms of thesis output, with a notable concentration in specific institutions. In terms of content, most of the theses focused on teaching topics, with frequent emphasis on physics subjects such as "dynamics" and "electricity". Methodologically, quantitative research designs were found to be the most commonly employed, with achievement tests being the primary data collection instruments. Additionally, through the use of VOSviewer software, a detailed visual mapping of thesis titles, keywords, and advisor distributions was conducted.
