小学数学课堂教学中应如何引入新知?可用如下七法:一、从数学本身发展的需要来引入新知教学中,教师要善于从现有知识出发,展示新旧知识之间的矛盾,引起学生的认识冲突,让学生在需要中进入新知学习。例如“分数初步认识”的教学,先让学生做等分除法,4个饼平均分给两个小朋友,每人几个?2个饼平均分给两个小朋友,每人几个?当学生列式解答说出算法后,老师提出:把一个饼平均分给两个
Primary school mathematics classroom teaching should be how to introduce new knowledge? The following seven methods available: First, from the needs of the development of mathematics to introduce new knowledge teaching, teachers should be good at starting from the existing knowledge, show the contradiction between old and new knowledge, arouse students’ awareness Conflict, so that students need to enter the new learning. For example, “the initial understanding of scores” teaching, let the students do equal division, the average of four pie divided into two children, each of several? 2 cake average to two children, each several? After the student solves the algorithm, the teacher proposes to divide the average of one cake into two
