教学必得有效。有三种视角可以用来界定有效教学,也就是可以从教学行为、教学投入与教学产出的关系来界定有效教学。下面是本人近二十年来从事中学物理教学过程中的一些关于课堂有效教学策略的心得,小结如下:一、集中精力,突破教学中的重点和难点一节物理课要让学生接受多个知识点和掌握一些基本技能,这就需要合理安排。教者是均匀分配时间讲解每一个知识点即平均用力,还是集中精力突破重点和难点?为此问题,笔者在两个平行班进行了多次教学试验。通过边讨论、 Teaching must be effective. There are three kinds of perspectives that can be used to define effective teaching, that is, effective teaching can be defined from the relationship between teaching behavior, teaching input and teaching output. Here are my experiences of teaching effective teaching strategies in high school physics teaching in the past two decades. The main points are as follows: First, concentrate on breaking through the key points and difficulties in teaching A physics lesson should allow students to accept multiple points of knowledge And master some basic skills, which requires reasonable arrangements. The teacher is evenly distributed time to explain each knowledge point that is the average force, or concentrate on breaking the key and difficult? To this end, I conducted two parallel classes in a number of teaching experiments. Through the discussion,
