学生在学习初中物理概念时,对于一些本质不同,但表面相似的概念很容易混淆。造成这种认识不精确的原因是多种多样的,有客观因素,也有主观因素;有教师教学的原因,也有学生学习的原因。研究学生在学习过程中易混概念形成的原因,寻找解决问题的有效策略,对于提高物理课堂教学效率,将会产生积极的作用。 When students study the physics concept of junior high school, it is easy to confuse some concepts that are different in nature but similar in appearance. The reasons for the inaccuracy of this kind of understanding are varied, objective factors and subjective factors. There are also some reasons for teachers ’teaching as well as reasons for students’ learning. Studying the reasons why students are confused in the learning process and finding effective strategies to solve them will have a positive effect on improving the efficiency of physics classroom teaching.
