有人认为:数学教学比较枯燥乏味,不像语文课堂教学那样生动、活泼、有趣。其实,那都是因为他们对数学教学认识不够,采用的教学方式比较单一,也就是教师讲学生听,纯粹的“填鸭式”教学。老师是演员,而学生扮演的只是听众、观众的角色,与真正意义上的数学教学背道而驰。针对这一现状,笔者结合自己的实际工作经验,层层深入、激发思维,以小学数学《圆的周长》一课为例进行了一系列的教学设计。 Some people think that: Mathematics teaching is boring, not as vivid, lively and interesting as the Chinese class teaching. In fact, it is because they do not have enough understanding of mathematics teaching, teaching methods used are relatively simple, that is, teachers tell students to listen to pure “spoon-fed” teaching. The teacher is an actor, and the student plays only the audience, the role of the audience, and the true sense of mathematics teaching runs counter to. In response to this situation, the author combined his own practical work experience, in-depth, inspire thinking, a primary school mathematics “circle perimeter” as an example for a series of teaching design.
