Mathematics Textbooks Research Trends in Turkey

The aim of this study is to reveal the general trends in studies on mathematics textbooks. In this context, 50 theses and 68 articles on mathematics textbooks between 2006 and 2018 were examined. Studies on mathematics textbooks were examined in terms of different variables such as year of publication, language, level of textbooks, learning area, subject, research design, data collection tool, sample, data analysis, validity-reliability methods, and the number of sources used. In order to evaluate the studies, the publication classification forms in the relevant literature were used. The findings obtained from the analysis of the studies were presented with the help of tables and graphs. As a result of the study, it was determined that researchers mostly used the Turkish language in publications and used domestic sources, and mostly examined textbooks at the secondary school level. Moreover, researchers mostly used the document analysis method, which is one of the qualitative research methods, and preferred the descriptive analysis technique in data analysis. It was found out that, in order to ensure validity and reliability, researchers mostly used direct citations, sources in the relevant literature, coding reliability and data analysis framework, respectively
