Spatial geometry is closely related to our lives. Geometric transformation raises geometry to a dynamic level, which helps students construct and manipulate the psychological representation of multidimensional objects. Student academic performance is closely related to opportunities to learn (OTL). Textbooks are the most important learning resource for students’ differences in OTL. Based on the perspective of OTL, this study has constructed an evaluation framework, studied the characteristics of the NCM textbook, a mainstream textbook of primary school mathematics in China, in terms of geometric transformation compilation, and discussed the compilation of textbooks.

摘要

Spatial geometry is closely related to our lives. Geometric transformation raises geometry to a dynamic level, which helps students construct and manipulate the psychological representation of multidimensional objects. Student academic performance is closely related to opportunities to learn (OTL). Textbooks are the most important learning resource for students’ differences in OTL. Based on the perspective of OTL, this study has constructed an evaluation framework, studied the characteristics of the NCM textbook, a mainstream textbook of primary school mathematics in China, in terms of geometric transformation compilation, and discussed the compilation of textbooks.
