Examining the questions in the 3rd and 4th grade mathematics textbooks according to math taxonomy

This research aims to evaluate the questions in the 3rd and 4th grade mathematics textbooks used in state primary schools according to the MATH taxonomy and to examine teachers' opinions on these textbooks. In the research, a case study design from qualitative research methods was used The research includes the 3rd and 4th grade mathematics textbooks used in the 2023-2024 academic year and a working group consisting of 22 third-grade and 22 fourth-grade teachers. Data were collected through semi-structured interview forms and textbooks. Document analysis and content analysis were conducted using the MAXQDA 24 program to analyze the data obtained from semi-structured interview forms and textbooks. The research results show that more than 75% of the questions in both textbooks belong to Group A, while the proportion of questions in Groups B and C is less than 25%. According to the teachers' opinions, most third and fourth-grade teachers do not use the textbooks effectively and primarily use them for practice and assessment activities. Teachers have indicated that the textbooks are particularly weak in terms of exercises and assessment activities. Additionally, they have noted deficiencies in the visual and formal design of the textbooks.
