The Characteristics Of Writing Examples In The Textbook Of Mathematics In China And Germany Compare Research

Sample questions are one of the three major organic components(text,examples,and exercises)of mathematics textbooks.Their important status is recognized by people.This article studies the characteristics of the writing of the fourth grade primary school mathematics textbooks in China,Singapore and Germany,and divides the research into three issues: 1.How to construct the text analysis framework for mathematics examples of three primary schools in the country,that is,from which The category analysis of textbooks text in the preparation of the characteristics of the examples? 2.In the text of textbooks,what are the characteristics of the three national textbook examples written on the framework? 3.Analyze the results and make suggestions for the compilation of examples of mathematics textbooks for primary schools and examples of teaching materials used by teachers.This article mainly uses the literature method,the content analysis method,the comparative research method,the statistical analysis method and so on research method to encode the text,the statistics and the analysis.The example text analysis dimension specifically includes the following six aspects: 1.The situation type that the sample problem belongs to;2.The example problem contains the illustration type;3.The problem problem includes the problem solving stage;4.The example problem belongs to the learning area;5.The example problem belongs to the content type;Examples include heuristics.The compilation of common examples and characteristics of three national textbook examples: 1.Focus on the situation of mathematics problems.Explain that the setting of textbook examples pays more attention to mastering the basic knowledge of mathematics;2.The presentation form emphasizes pictures and texts,accords with pupils' psychological characteristics;3.The numbers and algebraic contents are more;4.The heuristic methods are diversified.Some examples contain only one kind,while others contain a variety of mathematics inspiration methods;5,lack of historical data examples.Textbooks in Chinese textbooks are written with features: Focus on the cognitive and psychological characteristics of primary school students,and the contents of textbooks are on a daily basis;focus on the basics of examples.The Singapore textbooks are examples of writing features: Singapore textbooks contain the most examples of the three countries;pay attention to the mastery of mathematical methods.The German textbook example writes characteristic: The teaching material writes pays attention to the connection with other disciplines;Lack of "statistics and probability" study field examples.Based on this,suggestions are made from two aspects.1.Suggestions for the compilation of examples of primary school mathematics textbooks in China:(1)Increase the proportion of examples in relation to life situations and other disciplines;(2)Appropriately increase the proportion of examples of historical materials;(3)Appropriately increase the proportion of method examples.2.Suggestions for the use of textbook examples by primary school teachers in China:(1)Create problem situations and connect students with "mathematical reality";(2)Guide students to think in many ways and give full play to students' role;(3)Inspire student mathematics learning and inspire mathematics method.The main two directions of the follow-up study are: 1.Research on the content of other versions of textbooks in three countries;2.Study on the examples of mathematics textbooks for other grades in three countries.
