小学生好玩好动,注意力集中时间短,主要集中在课堂开始的一段时间,因此一节课的引入就很重要。从某种意义上说,课堂教学引入的好坏,直接影响着数学教学质量的高低。下面,我结合自己的教学实例,谈谈一节课该如何引入。1.开门见山法。教师以简洁明快的讲述或提问,开门见山、直截了当地引入课堂内容,迅速集中学生的注意力。例如人教版数学六年级上册“求一个数比另一个数增加(或减少)百分之几”这类问题的解题方法,一上课先出题:六年级 Pupils playful, focused attention is short, mainly concentrated in the classroom for some time, so the introduction of a lesson is very important. In a sense, the quality of classroom teaching has a direct impact on the quality of mathematics teaching. Here, I combine their own teaching examples to talk about how to introduce a class. 1. Open the door to see the law. Teachers with simple and neat to tell or ask questions, go straight to the point of introduction of the classroom content, quickly focus the attention of students. For example, the PEP sixth grade on the book “seeking a number than the other number of increase (or decrease) a few percent ” This kind of problem solving method, a class first question: sixth grade
