《数学课程标准》在“前言”中指出:“让学生亲身经历将实际问题抽象成数学模型并进行解释与应用的过程”;在“课程实施建议”中又提出:“让学生在生动具体的情境中学习数学”。因此,当前初中数学都非常注重情境的创设,连试卷、习题的题干因创设 The Standard of Mathematics Curriculum states in the Preface that “students are allowed to experience the process of abstracting practical problems into mathematical models and interpreting and applying them in their own hands.” In the “Suggestions for Implementing Curriculums” “Let students learn math in vivid concrete situations.” Therefore, the current junior high school mathematics are very focused on the creation of the situation, even the test paper, the problem stems from the creation of
