A Study On The Writing Features Of Worked Examples In The New Mathematics Textbooks Of Grade Two In Primary School

From the point of writing features of worked examples,the researcher carried out the study on the new mathematics textbooks of grade two in primary school in China,it can be decomposed into three sub problems: 1)How to revise and improve the framework of writing features of the worked examples in the new mathematics textbooks of grade two in primary school in China? 2)Summarize the common characteristics and their own characteristics on each category of the framework of the worked examples in each version's new mathematics textbooks;3)Put forward the valuable suggestions of highlighting the writing features of worked examples for the mathematics textbook writers.The first sub problem is difficult,the second is the key point,and the last is the foothold.According to the facts of the objects under study,the researcher tried to construct the framework for text analysis based on the related achievements.Then,studied the writing features of worked examples in the four versions of new textbooks of grade two(which were published by People's Education Press,Jiangsu Education Publishing House,Qingdao Publishing House,Shanghai Children's Publishing House)through such research methods as literature research,content analysis,comparison,in order to summarize the common characteristics and their own characteristics of writing features of worked examples in new mathematics textbooks of grade two in primary school,and put forward some suggestions of highlighting the writing features of worked examples in new mathematics textbooks for the writers.Through the research,the following main conclusions are obtained:Firstly,the framework of writing features of worked examples includes 7 categories: the field of knowledge,the problem expression,type of illustration,processing mode of knowledge,the inspiration,guidance of learning style,heuristic method.Most of the categories are divided into some sub categories.For example,the type of illustration includes: non illustration,decorative illustration,and functional illustration.If by content,the type of illustration can be divided into 5 sub categories: date chart,model diagrams,cartoon diagrams,life diagrams,demo diagrams.Secondly,the common writing features of the worked examples of the four versions new textbooks of grade two are as follows: the problem expression is inclined to interrogative sentence;the worked examples present a certain number of open examples;pay attention to the combination of pictures and texts;focus on contact with the students' life reality;attach importance to the process of knowledge formation;focus on presenting inspirations at key points;pay attention to the practical guidance and heuristic method.Thirdly,the following suggestions are proposed for the reference of the mathematic textbook writers in revising the next round of teaching materials: 1)Ensuring the writing personalization features of the worked examples;2)Appropriately increasing the proportion of open worked examples;3)Attaching importance to the compilation of illustrations with mathematical history;4)increasing the compilation and use of the demo diagrams;5)Emphasizing the compilation of “using equations” as one of the heuristic method;6)Straining every nerve to put “raising children's ability to ask questions” into practice.
