EXAMINATION OF SECONDARY SCHOOL STUDENTS' STUDIES ON MATHEMATICAL PROBLEM SOLVING IN NATIONAL THESIS CENTRE AND TR-DİZİN

The aim of this study is to make a descriptive content analysis of the articles related to mathematical problem solving from the theses in the National Thesis Centre and the journals of the faculties of education published in Tr-dizin and to determine the general trend. A total of 159 theses were included in the study. The studies were examined within the framework of the "Study Review Form on Mathematical Problem Solving Published in National Thesis Centre and Tr-dizin" prepared within the scope of the research. The related studies were analysed within the categories determined within the framework of sub-problems. Frequency and percentage distributions of the categories were calculated with the help of Excel programme and the data obtained were presented in detail with the help of tables. According to the results of the study, it was concluded that studies on mathematical problem solving were mostly conducted with 7th grade students, quantitative research methods were selected, quantitative analyses were performed and questionnaires and scales were preferred as data collection tools. It is thought that it will be useful in terms of seeing the strengths and deficiencies of the studies carried out in this field and it can be a guide for future studies in terms of seeing the trend of the studies from a holistic perspective.
