三年级是小学生学习的转折期,孩子的思想、心态变化较快。在数学的学习中还停留在低年级的思考方式上,不能做到认真审题、仔细读题,而是断章取义,支离破碎般地解决问题。针对这些现象,一方面要培养学生的学习习惯,包括听讲、作业、检验等习惯;另一反面,要及时关注孩子的学习态度,能积极面对困难和挫折。怎样在有限的课堂上发挥教学高效?我想还是要关注学生学习数学的兴趣,激发思维的灵活性;同时要有一些有效的教学策略,渗透一些数学的思想与方法,逐步形成知识的结构和体系。一、渗透数量关系,注重知识迁移通过几年的教学经验发现,学生对遇到有关速度、时间和路程的问题时,往往一知半解,答题处于碰运气 The third grade is the turning point of pupils learning, children’s thinking, mentality changes rapidly. In the study of mathematics still stay in the lower grades of thinking on the way, can not be serious exam questions, read the questions carefully, but out of context, fragmented solution to the problem. In response to these phenomena, on the one hand to develop students’ learning habits, including listening, homework, testing and other habits; the other hand, timely attention to children’s learning attitude, can actively face the difficulties and setbacks. How to exert efficient teaching in a limited class? I think we should still pay attention to students’ interest in learning mathematics and stimulate the flexibility of thinking. At the same time, we must have some effective teaching strategies to infiltrate some mathematical ideas and methods and gradually form the structure of knowledge and system. First, the number of infiltration, pay attention to the transfer of knowledge Through several years of teaching experience found that students encounter problems related to speed, time and distance, often know little or nothing, the answer is in luck
