摘要
在2019年人教A版高中数学教科书中,情境按照与高中学生经历的紧密程度可分为个人情境、简单科学情境、职业情境、社会情境和高级科学情境五个类型,教科书中五类情境均有涉及但所占比例不同。按照情境在“现实情境的数学表达”和“数学结果的现实解释”两个过程中发挥的作用,可各自划分为三个层次水平,教科书中现实问题的情境在两个过程的各层次作用水平上分布比较均衡,总体上高作用水平的情境在教科书中得到重视,并且相对更重视“现实情境的数学表达”过程。整体上教科书中数学应用的情境设置面向全体学生,符合我国新课标基础性和发展性的理念。
In high school mathematics textbook of 2019 PEP A Edition,context can be divided into personal,basic scientific,occupational,social and advanced scientific context according to the closeness with students'experience which had different proportion in textbook.According to context's role in the process of mathematical expression in reality and realistic explanation of mathematical result,context can be divided into three levels and the context of realistic problem in textbook is distributed with balance in.the three levels.Overall,textbook emphasizes high level context and the former process.Mathematical application context in textbook is designed for all students,which is consistent with the fundamentality and expansibility concept of new curriculum standards.
