中、加、美中学数学教材习题情境的比较分析——以“不等式”专题为例

Comparative Analysis of Exercises in Mathematics Textbooks of Middle School,Canada and America——Taking "Inequality" as an Example

本文以中国人教版、加拿大BC省版、美国加州版的中学数学教材为研究对象,对教材中不等式专题的习题情境进行比较分析,分析方向主要为习题情境分类以及习题情境的真实度。研究结论为:在习题情境分类方面,无情境所占比例最高,这与所选专题有关。就其他情境而言,美国教材较注重个人情境,中国教材则注重社会情境,加拿大教材则在个人、社会以及科学情境三方面都比较均衡;在习题情境的真实度方面,中国教材的非真实情境占比例高,加、美教材则是真实情境比例高。

This paper takes the Chinese Edition,BC Province Edition of Canada,California Edition of the United States as the research object,compares and analyzes the exercise situation of inequality topic in the textbook,and the analysis direction is mainly the classification of exercise situation and the authenticity of exercise situation.In other contexts,American textbooks pay more attention to personal situation,Chinese textbooks pay more attention to social situation,Canadian textbooks are more balanced in personal,social and scientific situation,and Chinese textbooks account for the proportion of non-real situation in exercise situation.For example,the teaching materials in Canada and America are relatively high in real situations.
