建构主义理论提出:“知识不是通过教师的传授获得的,而是学习者在一定的情境即社会文化背景下,借助其他人(包括教师和学习伙伴)的帮助,利用必要的学习资料,通过意义建构的方式获得的。”这与高中物理课程的理念是一致的,如何创设合理有效的教学情境,是高中物理实现高效课堂的关键。新课程理念要求教学过程是一个多元化的动态过程,是以课堂为阵地、多媒体手段为载体的师生交流互动过程,所以必须转变学习方式、改变以往那种灌输式、填鸭式的机械训练,建 Constructivism theory suggests: “Knowledge is not obtained through the teaching of teachers. Instead, learners, with the help of other people (including teachers and learning partners), make use of the necessary learning materials through certain contexts, that is, social and cultural backgrounds, and through Meaning construction. ”This is consistent with the concept of high school physics curriculum. How to create a reasonable and effective teaching situation is the key to achieving an effective classroom in high school physics. The concept of the new curriculum requires that the teaching process be a diversified and dynamic process, which is a process of exchange and interaction between teachers and students taking the classroom as a venue and multimedia means as the carrier. Therefore, it is necessary to change the learning style and change the traditional type of mechanical training, build
