The aim of the present study was to investigate the educational activities of the preschool mathematics books regarding geometric shapes using documentary method. For the analysis, we used the document published in 1396 (2017) by the Ministry of Education in Iran for preschool level., as well as the zero, first and second level of the revised Van Hiele Model (Clementes and Batista, 1992) including Pre-recognition, Syncretic and analysis as the criteria. At first level, 10 criteria for analyzing activities of geometry shapes from the first three levels of the revised Van Hiele Model (Clementes and Batista, 1992) exteracted. Then five textbooks which were recommended by Education Growth Bibliography, Welfare Organization and several preschool centers selected and their geometric shapes content evaluated according to the 10 extracted criteria. Results showed the highest frequency of educational activities belonged to level one and the lowest frequency beloged to zero level of the revised Van Hiele model. The study concluded that the content of the preschool mathematics books needs to be revised and the educational activities of higher level than two recommended to be transferred to higher grade mathematics textbooks.

This study is to explain the criteria and indicators of the ideal form of school mathematics curriculum in Iran. For this purpose, the national documents of the education system in Iran and related research findings to school mathematics curriculum were examined. The Akker’s ten-component model for the curriculum was adapted as the framework for this study. In order to ensure the balance and effectiveness of the curriculum, in this framework, each of the components address a specific question. By answering them, criteria for the components of the school mathematics curriculum were presented. The research method of the study was document analysis and qualitative content analysis in the form of inferential. To validate the presented criteria, a number of mathematics educators and curriculum specialists participated in this study. Finally, for each of the components introduced in the framework, the criteria and indicators of the ideal form of mathematics curriculum were determined.

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.
