苏教版国标本数学教材,生活情境性非常强。它贯穿了这样的一种理念:数学来自于生活,生活中处处有数学,数学必须为生活服务;数学是有价值的;它给教师提出了一个重要的话题,就是如何以开放的态度来进行教学活动。过去那种在纯数学的环境下进行的封闭式教学已完全不能适应现在的课本内容了。首先应该看到的是,课本中留给我们自己去开发的数学课程资源非常丰富。这就给教师设计开放性数学题目提供了依据和可能。 Sujiao version of the national standard textbooks, life situation is very strong. It runs through the idea that mathematics comes from life, that there are maths everywhere in life, that maths must serve life, that maths are valuable, and that it raises an important topic for teachers that is how to proceed with an open mind Teaching activities. In the past, closed-door teaching in a purely mathematical environment was completely out of place for the present textbook. The first thing you should see is that there are plenty of math curriculum resources left in the textbook for us to develop. This provides teachers with the basis for the design of open math problems and possibilities.
