the challenges of implementing the mathematics curriculum

Following the latest mathematics curriculum reform of the first cycle of elementary education in Iran and the experience of about a decade of implementation of this program, the aim of the present study was comparing the intended implementation of this program with the implemented mathematics curriculum. The framework used in this study is Akker's 10-element model, which considers the various components in the curriculum. Identifying the characteristics of the implemented mathematics curriculum in the first period of elementary school was done using the triangulation design. For this purpose, qualitative data were collected through observing the teaching process in classrooms, semi-structured interviews, teachers' reports, and focus groups. The findings of this study showed some differences, shortcomings and weaknesses in the implementation of the curriculum, which were discussed and presented separately for the elements of the program. Finally, 25 solutions emerging from the findings of this research were proposed for future planning.
