In this study, between the years 2000-2020 those studies to solve problem in the field of mathematics education in Turkey was aimed to examine the content analysis method. In this study, one of the qualitative research methods, case study design was used. Document analysis method was used for data collection and content analysis method was used for data analysis. In this study, the data obtained from the publication year of the studies for problem solving, research groups, research methods, data collection tools and results were created by using frequency and percentage calculations and the findings were reached. When looking at the studies on problem solving, it was determined that the number of studies has increased since 2005, mostly secondary school students are employed, quantitative research methods and experimental research design are applied the most, and test data collection tool is used the most. It was concluded that non-routine problem solving and creative problem solving skills were not sufficient, reading skill had an effect on problem solving skills, and there were insufficiencies in understanding the problem, planning and evaluating the problem.
