A Study on Characteristics and Functions of Non-textual Elements in Junior High School Mathematics Textbooks:An Example of Zhejiang Education Press Series of Textbooks
Non-textual elements(NTEs)are an indispensable part of mathematics textbooks.However,some researchers have found that some parts of NTEs are partial to decoration,have single functions,and are not closely related to mathematics.Therefore,in this study,we take the ZEP series of mathematics textbooks as an example to analyze the rationality of NTEs by comparing the categories and functions.The results show that Grade 8 contains the largest number of NTEs,and the average density of NTEs in Grade 9 is the highest.In terms of categories and functions,NTEs have the largest number in the mathematics category and mainly have explanatory functions.In addition,we found that NTEs in the life category mainly have decorative functions,while NTEs in the life category mainly have decorative and explanatory functions.In the future,NTEs can be further considered in terms of substantive connection with mathematical content and richness of functions.
