数学教学中板书的功能 1.能使教学内容及重点、难点一目了然,有利于学生鲜明深刻地理解、掌握老师所讲授的内容。 2.能留下一堂课教学内容的缩影,启发学生思维、回味、巩固所学知识,为课后复习提供方便。 3.发挥了无声语言的作用,帮助学生提高数学表达能力。常常有学生对某些问题(如某概念的严格定义、某几何图形的性质)是心明口不明,难以书面表达,而正确
The function of the blackboard book in mathematics teaching 1. Can make the teaching content and key point, difficult point clear at a glance, help the student understand profoundly, master the content that the teacher teaches. 2. Can keep a miniature of the teaching content of the next class, inspiring students’ thinking, memorizing, consolidating what they have learned, and providing convenience for review after class. 3. Play the role of silent language to help students improve their mathematical expression skills. Often students have problems with certain issues (such as the strict definition of a concept, the nature of a geometric figure) that are unclear, difficult to express in writing, and correct.
