义务教育数学教材内容的螺旋式编写特点研究——以轴对称为例

Research on the Spiral Writing Features of Mathematical Textbook Content in Compulsory Education Stage——Taking Axis Symmetry as an Example

采用内容分析法,从内容广度、螺旋间隔和内容深度3个维度对现行6个版本的义务教育数学教材中轴对称内容的螺旋式编写特点进行研究,发现:随着学段递升,各版教材中螺旋式内容的广度或深度基本上都有实质性的增加,同一版本教材中不同知识内容及不同版本教材中的同一知识内容在螺旋间隔上差异较大.提出反思建议:某些教材的基本观念需要适度渗透与螺旋,学科逻辑与年龄特征应当兼顾,各个螺旋之间需考虑有效衔接.

The research on the spiral writing characteristics of mathematics textbook contents is carried out,in which axis symmetry content in the 6 editions mathematics textbooks being used in compulsory education stage is the study object and content analysis is adopted from the three dimensions of content breadth,spiral interval and content depth.The results found are as followed.With the rise of the school stage,the breadth or depth of the spiral content in each edition of the textbooks has basically increased substantially.The different knowledge content in the same version of the textbooks and the same knowledge content in the different version of the textbooks are quite different in the spiral interval.In some textbooks,the basic concepts need to be penetrated and spiraled moderately,subject logic and age characteristics should be balanced,and effective cohesion between spirals needs to be considered.
