A Study Of Example Exercises In The Mathematics Textbook Of High-grade In Primary School Under The Core Literacy

The Mathematics Curriculum Standards for Compulsory Education(2022 edition)(hereinafter referred to as the Curriculum Standards(2022 edition))clearly states that the curriculum goal of mathematics education is to develop students’ core mathematical literacy in an all-round way.As an important intermediary system to carry out the core literacy concept of teaching materials in the teaching process,mathematics teaching materials form and develop students’ core literacy through the examples in the teaching materials,which is direct and important.Therefore,it is necessary and urgent to study the core literacy level of the textbook example exercises.Based on the core literacy of the 11th Primary School Mathematics proposed by the curriculum standard(2022 edition),the paper takes the mathematics textbooks of the fifth and sixth grade six as an example,and according to the core literacy evaluation framework theory of Teacher Yu Ping,constructs the core literacy evaluation framework of the primary school mathematics example exercises.From knowledge understanding,knowledge transfer and knowledge innovation three dimensions of textbook example exercises core literacy level analysis and the unit content into different mathematical field,different areas of core literacy level comparative analysis found that elementary school mathematics textbook example exercises in the process of implementing the core literacy concept of concept and knowledge is not close,concept to carry out uneven problems.In order to further explore the textbook example exercises problems in the implementation of the core literacy process,the paper interview outline interview of 10 a line elementary school mathematics teachers,and combined with the analysis of the third chapter of the core literacy level results,from the perspective of teaching materials,teachers and students of elementary school mathematics textbook example exercises to carry out the existing problems of the core literacy cause analysis.Finally,according to the analysis of the problems and causes of the implementation of the core literacy,based on the teaching practice,in the fifth chapter,the following four suggestions on the implementation of the teaching materials:First,understand and explore the connotation of the core literacy;Second,grasp the "degree" of the textbook exercises;Third,enrich the teaching design and clarify the teaching style;Fourth,improve the teaching and research level.
