课堂教学是学生获取知识的一段重要经历。数学教育,是一项具有现实意义的活动,理应对现实生活的世界和客观的数学世界做好恰到好处地沟通。怎样沟通,我是从以下两方面实施的。一、生活世界数学化1.利用学生熟悉的生活情境学习数学在教学“可能性”一课时,我先给学生讲大家都熟悉的《狼来了》的故事,然后提出问题:“如果大家都不来救这个孩子,接下来可能会发生什么事情呢?”学生就会很自觉地联系他们已有的经验,回答可能出现的各种情况。老师再问:“在我们身边还有哪些事情可能发生?哪些事情根本不可能发生?哪些事情发生的可能性很大呢?”这一情境的导入,使学生发现“可能性”就在生活中。2.结合已有的生活经验,解决一些实际的数学问题
Classroom teaching is an important lesson for students to acquire knowledge. Mathematics education is an activity of real significance. It is appropriate to communicate properly with the real world and the objective mathematical world. How to communicate, I implemented from the following two aspects. First, the mathematical world of life 1. Using the familiar life situations of students to learn mathematics teaching “Possibilities ” a lesson, I first tell students all familiar “wolf” story, and then ask questions: “ If everyone does not come to save this child, what happens next? ”Students will consciously contact their existing experience and answer all possible situations. The teacher asks again: “What else is possible around us, what is impossible at all, and what is likely to happen?” “The introduction of this situation allows students to discover” possibilities " In life. 2 combined with existing life experience, to solve some practical mathematical problems
