Practical Research On The Teaching Of Physics Concepts From The Perspective Of Constructivism

The concept of physics is a high degree of abstraction and generalization of physical phenomena and processes.The concept of physics is the cornerstone of the physical knowledge system.The teaching of physical concepts is of utmost importance.If students do not really understand the concept of physics,they will affect the learning and mastering of subsequent physics knowledge and the improvement of physics teaching quality.This article mainly uses the methods of literature research,the investigation research and the experimental research,aims to explore a kind of teaching method that suits the student to construct the physical concept autonomously.The physical concept teaching questionnaire was designed to analyze the current situation of high school physical concept teaching and put forward measures to improve the physics teaching in high schools.This article is guided by the theory of constructivism.In order to enable students to construct a clear physical concept,an experimental study of a semester was carried out.First,the former concept of the existence of three related contents of electromagnetics in high school students was tested and analyzed,and the students were found to have no preconcept of some contents.The preconcept of some contents of the students is conducive to the construction of the scientific concept.Some of the students are not thorough enough to understand the previous concepts,and even the understanding is too one-sided,causing the students to have some wrong preconcepts of some contents.Second,it proposes to guide instructional design in physical concept teaching based on constructivism theory,and applies it to the three concept teaching of high school electromagnetics.It compares with physical concept teaching adopting traditional instructional design to carry out research,and compares the test performance of students before and after experimental research.The research results show that:teaching instructional design based on constructivism theory for physical concept teaching is more suitable for students to construct and understand physical concept conceptually than traditional teaching design.At the same time,it is also conducive to stimulating students' interest in learning physics,mobilizing students'enthusiasm physical learning,and improving the quality of physics teaching.The research is conducive to optimizing the physical concept teaching at high school,and meanwhile provides a reference to concept teaching for high school teachers in physics.
