备课与上课是教学中两个最重要的环节。在备课这个环节主要解决如下三个问题:一是教师的备课笔记是否需要检查;二是以往的备课笔记能否用,如果能用应该怎样用;三是备课笔记上是否一定要有三维目标、教具、重难点等这些内容。课堂教学主要是针对课堂探究的几个要素是否一定要齐全,如课堂探究一定要有猜想吗?怎样验证猜想?这种验证需要吗?怎样实验?实验想培养学生什么?想达到什么目的?课堂上一定要有合作讨论吗?如此等等的一些问题。我们强调在备课及课堂教学上决不能形式化、绝对化!而是一定要从教学的实际及实效出发,从而切实提高物理课堂教学的实效性。
Preparation and teaching are two of the most important aspects of teaching. In this part of the lesson preparation mainly to solve the following three questions: First, the teacher’s preparation notes need to check; Second, the past preparation notes can be used, if we can use how to use; Third, preparation notes must have a three-dimensional goals, Aids, heavy and difficult to wait for these contents. Classroom teaching is mainly for the classroom to explore several elements must be complete, such as classroom exploration must have a guess? How to verify the conjecture? This verification needs? How to experiment? Experiment want to train students what? Want to achieve what? There must be cooperation on the discussion? So some of the problems. We emphasize that lesson preparation and classroom teaching must never be formalized or absoluteized. Instead, we must proceed from the actual and effective teaching so as to effectively improve the effectiveness of physical classroom teaching.
