“可能性”这一教学内容在目前的小学数学教学中是一个全新的内容,属于“统计与概率”这一知识领域中“概率”的范畴。由于概率知识本身比较抽象,小学生在学习这方面的内容时,存在一定困难。所以教学这些内容时,应以直观内容教学为主,渗透一些概率的思想。下面就几个教学片段来谈谈自己的思考和体会。[片段一]激趣导入上课伊始,教师和学生谈心:同学们喜欢打乒乓球吗?你最喜欢的乒乓球运动员是谁?(同学们表现得都非常兴奋。有的说王浩,有的说马林,顿时课堂热闹起来。) “Possibility ” This teaching content is a brand new content in the current elementary mathematics teaching, belonging to the category of “probability” in the field of “statistics and probability”. As the probability of knowledge itself is more abstract, primary students in learning this content, there are some difficulties. Therefore, teaching these contents should be based on visual content teaching, infiltration of some probability of thinking. Here are a few teaching fragments to talk about their thinking and experience. [Fragment one] Interesting introduction At the beginning of the class, teachers and students talk about: students like to play table tennis? Your favorite ping-pong player who? (Students were very excited .Some say that Wang Hao, and some Marin, suddenly lively in the classroom up.
