数学教学从本质上来说不同于其他学科,它以培养学生逻辑思维和计算能力为主,同时它也是生活中的一个非常重要的工具.因此,作为数学教学工作者,务必以“培养学生能力”和“教会学生用数学”为主要目标去实施教学.那么如何才能做到这两点呢?我想,应该在有限的教学时间内,加强学生辨析思维能力,通过教学中的不断变化,让学生真正掌握数学知识的本质,从而达到提高课堂效率且又做到对人的培养的双重任务!下面将通过几个案例,来谈谈变式训练给课堂高效带来的 Mathematics teaching is essentially different from other disciplines, it is mainly to cultivate students ’logical thinking and computing ability, at the same time it is also a very important tool in life.Therefore, as a math teaching worker, be sure to "cultivate students’ abilities How to do these two things? I think we should strengthen students’ ability to discriminate and solve their thinking through the teaching during the limited teaching time Change, so that students really master the essence of mathematical knowledge, so as to achieve the double task of improving the efficiency of the classroom but also to the cultivation of people! Here will be a few cases to talk about the transformation of training to bring efficiency to the classroom
