新课程标准强调数学课堂教学要创设有效的情境,让学生经历知识的产生、形成和应用的过程。数学情境是从教学的需要出发,创设与教学内容相适应的、含有以相关数学知识和数学思维为价值取向的刺激性的数据材料或背景信息。情境中的材料和信息是实际问题或是纯数学问题,应能激起学生的求知欲,引起学生对问题积极思考,同时也是学生熟悉的,有利于学生从中发现数学实质。好的数学情境要具备趣味性、现实性和数学性。
The new curriculum standards emphasize that mathematics classroom teaching should create effective situations and let students experience the process of producing, forming and applying knowledge. The mathematics situation is based on the teaching needs, and establishes the stimulating data material or background information that is compatible with the teaching content and has the value orientation based on the relevant mathematical knowledge and mathematical thinking. Situational materials and information are practical problems or purely mathematical problems, should be able to arouse the students’ thirst for knowledge, causing students to think positively about the problem, but also familiar to the students, is conducive to students to find the essence of mathematics. Good mathematical situations should be interesting, realistic, and mathematical.
