教师在教数学的概念、性质、定律和法则等基础知识中,固然要把思考方法教会学生,而在巩固练习中,也要把思考方法作为训练的一个重要内容。这是培养和发展学生的逻辑思维能力的重要环节之一。最近,我听了一些老师的数学课,在这方面颇受启发。一位四年级的数学老师,教学第七册正向的两次归一的应用题时(P65例5),讲清了这类题的结构特征和解题的思考方法后,补充了如下的三道巩固题,请学生解答,并说出每步计算的思考过程。 1.一个工人6天修600米,照这样计算,3个工人8天修路多少米?
Although teachers should teach their students ways of thinking in the basic concepts of the concept, nature, law and law of mathematics teaching, they should consider the method of thinking as an important part of their training in consolidating their exercises. This is one of the most important steps in developing and developing a student's logical thinking ability. Recently, I listened to some teachers math class, very inspired in this regard. A fourth grade math teacher, teaching the seventh book positive two application questions (P65 5), clarified the structural characteristics of these questions and problem-solving method of thinking after the addition of the following Three consolidated questions, ask students to answer, and say the calculation of each step in the process of thinking. 1. A worker six days to repair 600 meters, according to this calculation, three workers 8 days road repair how many meters?
