一堂成功的物理课离不开课堂教学主线的构建。教学时教师如果能抓准这条主线,同时拓展到整个教学过程,就能顺畅地实现整体感知和整体把握,从而使课堂条理清楚,大大提高教学的效率。本文以“光的反射”的课堂教学为例,谈谈在初中物理课堂教学中如何通过创设问题情境,让学生在一条主线的情境课堂中充分体验获取知识的规律。一、创设问题情境,激发学习关注实录片断1“光的反射”课题的引入师深圳的冬天总少不了给人温暖的阳光,而在意大利北部的维佳维拉人却遭遇沉重的苦恼,下面我们一起去看一下。师播放视频。师坐落在狭长的山谷中的维佳维拉,在每年
A successful physics class can not be separated from the main line of classroom construction. If teachers can grasp this main line of teaching while expanding to the entire teaching process, we can smoothly realize the overall perception and overall grasp, so as to make the class clear and greatly improve the efficiency of teaching. In this paper, we use “reflection of light” as an example to discuss how to create a problem situation in junior middle school physics classroom so that students can fully experience the law of obtaining knowledge in a mainline contextual classroom. First, the creation of the problem situation, to stimulate the learning of the recorded piece 1 “reflection of light ” project introduction division Shenzhen winter always give a warm sunshine, but in northern Italy, Vegaweila suffered heavy distress, Let’s take a look at this Play video. The division is located in the narrow valleys of Vega Vera, each year
