新课程标准中首次提到了数学模型的概念,同时严士键教授也在《数学教育应面向21世纪而努力》一文中指出:“分析问题和解决问题通常意味着以下一些环节:将实际问题化成可以处理的但又对原来的问题有用的数学问题,寻找或创造适当的解决问题的数学方法(包括计算方法)。”我认为,分析和解决实际问题的能力实质就是数学建模的能力。那么,我们的小学数学课堂应该怎样引导学生建构数学模型,从而提高学生解决实际问题的能力呢?
The concept of mathematical models was first mentioned in the new curriculum standards. Professor Yan also pointed out in his article “Mathematics education should work towards the 21st century:” Analyzing and solving problems usually means the following steps: Mathematical problems that are solved but are useful to the original problem, and find or create appropriate mathematical methods (including calculation methods) to solve the problem. “” In my opinion, the ability to analyze and solve practical problems is essentially the ability of mathematical modeling. So, how should our elementary mathematics classroom guide students to construct mathematical models to improve students’ ability to solve practical problems?
