对于如何优化课堂教学,我在教学实践中,体会较深的有以下几点。 一、找准知识的起点是关键 数学知识的特点是逻辑性强。知识的链条环环紧扣,螺旋上升。每学习一项新知识,一般都要以前面的知识作基础。因而,备课中教师首先要研究新知识与哪些原有的知识有联系,找准新知的起点,进而设计恰到好处的复习,为学习新知搭桥铺路。如果起点定得低,组织复习的内容简单冗长,复习耗时过多,挤掉新授课的时间,形成喧宾夺主的现象。如果起点定得高,不利于理解接受新知识,不能促成知识的顺利迁移。
For how to optimize the classroom teaching, I practice teaching, experience the deeper have the following points. First, find out the starting point of knowledge is the key to mathematical logic is characterized by strong logic. Knowledge of the chain ring tightly, spiral up. Each learning a new knowledge, generally based on the previous knowledge. Therefore, the preparation of teachers should first study the new knowledge and what the original knowledge of the relationship, identify the starting point for new knowledge, and then design the right review, paving the way for learning new knowledge. If the starting point is set low, the contents of the organization review is simple and lengthy, review time-consuming too much, squeeze out the time of the new lectures, the formation of overwhelming phenomenon. If the starting point is set high, which is not conducive to understanding and accepting new knowledge, it can not lead to a smooth transfer of knowledge.
