Content Analysis And Use Research Of "Triangle" In The Primary School Mathematics Textbook Of Jiangsu Edition

Textbooks have an unshakable position in the curriculum reform of basic education in China.They not only affect the teaching quality of teachers,but also affect the comprehensive quality of students.As a product of the background of "one syllabus and multiple textbooks",the textbook of Jiangsu Edition is representative.As an important part in the field of "graphics and geometry" in the textbook,the Triangle content is of great significance for students to establish space concepts and develop geometric intuition and reasoning ability.Through the analysis of the Triangle content in the primary school mathematics textbook of the Jiangsu Edition,summarizes the characteristics of the textbook compilation,provides the direction for teachers to use the textbook,and lays the foundation for exploring and discovering the problems in the use of textbooks.The use of textbooks mainly focuses on the comparison between the intention of textbook compilation and actual use.Starting from the dimension of textbook analysis,on the basis of learning from the existing research models of textbook use,form a research framework of textbook use in line with this study,and establish the dimension and content of textbook use research.Using the methods of questionnaire,interview,classroom observation,etc.from three stages and nine specific dimensions of pre-class,in-class and post-class,investigates the current situation of the use of textbooks for teachers in the Triangle,and finds the following problems:mathematics teachers lack in-depth study of the curriculum standards,especially among the new teachers;Teachers generally pay insufficient attention to the "Do you know" column in the textbook;The level of teachers’ integration of relevant teaching resources needs to be improved;Teachers have weak awareness of judging textbooks.Finally,based on the analysis of the textbook and the results of the survey,this paper puts forward practical strategies and suggestions for the use of primary school mathematics textbooks:Effectively understand mathematics curriculum standards in various ways;Conduct diversified mathematical treatment for the column "Do you know";Reasonably design and develop textbook resources;Cultivate teachers’awareness of criticizing textbooks in reflection.
