《数学课程标准》指出:“要在发展学生双基的基础上,让学生感悟数学思想,积累活动经验。”如何理解“活动经验”这个概念呢?它是间接经验,还是直接经验?显然,直接经验更有利于学生数学思想的发展。那么,学生如何才能在课堂教学中积累直接经验,感悟数学思想呢?下面,通过对吴正宪老师教学“解决问题”一课的赏析和反思,谈谈对这个问题的看法。一、复习旧知,发展符号思想解决问题是数学活动的核心,需要学生通过观察、思考、推理等活动明白事理,培养学生提出问题、解决问题的意识和能力,形成基本的解题策略。课堂中,吴老师用课件展示例题(树上有5个桃子,树 The standard of mathematics curriculum states that: “Students should be seized with mathematical ideas based on the development of students’ double basics and accumulate experiences of activities.” How to understand the concept of “activities of experience”? Is it indirect experience or direct Obviously, direct experience is more conducive to the development of mathematical thinking of students. So, how can students accumulate direct experience in classroom teaching, sentiment mathematic thought? Now, through the Appreciation and reflection on the teaching of Wu Zhengxian “problem solving ”, talk about the views on this issue. First, review the old knowledge, the development of symbolic thinking Solving the problem is the core of mathematics activities, students need to understand things through observation, thinking, reasoning and other activities to understand and cultivate the students to raise awareness and ability to solve problems, the formation of a basic problem solving strategy. In the class, Wu showed examples with courseware (there are 5 peaches and trees in the tree
