《数学课程标准》指出:我们的教学要“从学生已有的生活经验出发,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”。然而在实际的教学过程中,我们发现:现行教材的典型性、数学学科本身的抽象性、教师教学的大众性,都时常将学生转入难以理解的“抽象世界中,使得部分学生因此而丧失学习的兴趣与动力。为此,我 The Standard of Mathematics Curriculum states: ”Our teaching should“ start from the students’ existing life experiences and allow students to experience the process of abstracting practical problems into mathematical models for interpretation and application ”. However, in the actual teaching process, we find that the typical teaching material, the abstraction of mathematics itself, and the popularity of teachers’ teaching always turn students into difficult to understand “abstract world” Loss of interest and motivation in learning
