Research On The Concept Of Wave In Middle School Physics Teaching

Physical concepts are the base of physics. They are also the important part of physics. Classroom teaching of physical concepts plays an important part. But it has also been a difficult aspect of physics teaching while abstract physics concepts teaching and learning is a more puzzled problem for the teachers and students. Among them, the typical one is the concept of wave.This thesis does some research on the concept of wave and its relative teaching problems from angles based on the teaching design and concept teaching. First, it analyzes the related knowledge of the concept of wave from the intension and extension. By investigating the textbooks of nearly 20 years and the arrangements of the contents about wave, it analyzes the addition and deletion of the contents and the transformation of the philosophy of curriculum because of them. Questionnaires and interviews are used to investigate the learning situation of the concept of wave and the main obstacles during the learning course of the concept of wave. The main reasons are the influence of the pre-concept and the abstract of the concept. Strategies for teaching them are also offered, so are the manipulative models of teaching design with the theoretical direction. And they have been practiced in the teaching.This thesis tries to offer an idea on the concept of wave researching and learning by researching on the concept of wave from angles. It just offers a few commonplace remarks by way of introduction so that others may come up with valuable opinions.
