在数学的教学中,教师应成为学生学习活动中的启发者、质疑者和促进者.教师如何发挥好自己的“导向”作用,使学生成为学习的主体,这就需要教师对课堂教学中的问题进行科学、合理的设计.一、由特殊到一般教学过程中问题的设计不但要使得学生掌握知识还要使学生掌握相关的思想方法.在课本中有一些定理是由一些特殊的结论推导出一般的结论.如,正弦定理的提出是在直角三角形中有asin A=bsin B=csin C,那么在任意的三角形中是否有这样
In mathematics teaching, teachers should become the enlighteners, challengers and promoters in the students’ learning activities.How to play a good role of teachers in making students become the main body of learning, which requires teachers to classroom teaching In a scientific, rational design.First, from the special to the general process of teaching design problems not only to enable students to master the knowledge but also to enable students to master the relevant methods of thinking in the textbook there are some theorems are some special conclusions Derive the general conclusion.For example, the proposed sine is in the right triangle asin A = bsin B = csin C, then in any triangle whether there is such
