本文基于PISA数学素养框架情境分类和其他情境分析模型,构建了分析数学问题情境的四个维度,即背景素材特征、语境呈现方式、语境干扰程度和任务挑战水平,并选取浙教版和沪教版小学数学教材“带余除法”的内容,对两个版本教材的问题情境水平进行比较,从上述四个维度作出总结并据此提出改进教材编写的一些建议。
Based on PISA math framework framework and other contextual analysis models, this paper constructs four dimensions to analyze the situation of math problems, namely background material characteristics, context presentation, contextual interference and task challenge. Shanghai Jiao Tong Primary School mathematics textbooks “with the remainder and division ” content, the two versions of textbooks to compare the situation level of the problem, from the above four dimensions to make a summary and put forward some suggestions to improve the preparation of textbooks.
