Generally, textbook users pay more attention to the knowledge and skills to teach than the logical sequence of contents. Among other factors, the quality of a mathematic textbook, especially for beginners, is largely determined by the organization and presentation of contents with regard to learners' developmental age. The overarching goal of this research is to highlight the coherence of content organization and to propose some suggestions in order to improve the quality of textbooks. In this study, a sample of approved textbooks was taken in these three countries. After a summary of the big ideas fostered by these two approaches, the textbooks were compared to see the commonalities and differences on how SPA and CPA are applied. It revealed that the three textbooks are anchored on spiral progression, even if the chapter on addition has been developed with some differences with regard to the number of lessons and the materials used in teaching activities. Concretely, Singaporean and Japanese textbooks prioritize an in-depth teaching of a relatively limited set of contents, with a variety of materials and techniques. Meanwhile, Senegalese textbooks focus more on breadth than a deep teaching, some contents being overstressed, others such as addition of three numbers not dealt with in the two grades. This study would likely help to reconsider the content organization in case of curriculum and textbook revision, especially for the newly generalized curriculum in Senegal.}, pages = {101--111}, title = {Analysis on Lower Graders' Mathematics Textbooks in Senegal, Japan and Singapore, in Application of Spiral Structure of Its Contents and Concrete, Pictorial and Abstract (CPA) Approach}, volume = {14}, year = {2021} }
