在中学阶段开设数学课程,一方面是为了让学生掌握一定的数学基础知识和基本技能,另一方面是为了培养学生的思维能力、创新能力,让学生理解和运用数学思想和方法。两者相比较,后者更为重要。《义务教育数学课程标准(2011年版)》指出:“在呈现作为知识与技能的数学结果的同时,重视学生已有的经验,使学生体验从实际背景中抽象出数学问题、构建数学模型、寻求结果、解决问题的过程。”根据《课标》编写的苏科版初 The establishment of mathematics courses at the middle school stage is to allow students to master certain basic mathematics knowledge and basic skills. On the other hand, it is to cultivate students’ thinking ability and innovation ability so that students can understand and use mathematical ideas and methods. The latter is more important than the latter. The “Mathematics Curriculum Standards for Compulsory Education (2011 Edition)” points out: “In the presentation of mathematical results as knowledge and skills, we must pay attention to the students’ existing experience so that the students’ experience can abstract mathematical problems and build mathematical models from the actual background. The process of seeking results and solving problems.”
