Research On The Change Of Oid And New Teaching Materials In High School Physics Take Modern Physics As An Example

This research mainly takes the high school modern physics part as the research object,carries on the systematic research to the curriculum standard and the teaching material content development change in the recent 20 years.This paper first expounds the research background,the change of curriculum standard and the role of modern physical knowledge in the development of human history and civilization and the development of the subject,discusses the fact that modern physics is constantly excavated by human beings and used in modern science and technology.Secondly,this paper studies the changes of curriculum standard and outline of high school physics in the past twenty years,compares the changes of curriculum standard before and after the new curriculum reform,analyzes the changes of breadth and difficulty of the curriculum,and then combs the relevant knowledge,and concludes the development and changes of important knowledge points in modern physics.It is concluded that photoelectric effect and calculation of hydrogen energy level are the eternal important knowledge points in modern physics,and also the teaching difficulties in modern physics.In the third chapter,this paper compares the contents,illustrations,examples,exercises and columns in the three editions of the textbook,analyzes how the textbook changes according to the requirements of the curriculum standards,makes comparative analysis and exploration of the new and old textbooks,and finds out the major changes and analyzes the corresponding reasons.In the fourth chapter,based on the present situation of classroom teaching,this research adopts the way of questionnaire,the anonymous questionnaire was carried out on the high three students,for students to modern physics knowledge of high school,at the same time,the author to interview of front-line teachers,so as to understand the current in the actual teaching of middle school students of modern physics part of the knowledge of the actual situation and the problems existing in the students themselves,Whether the teaching concept of teachers changes with the adjustment of the content and analyze the corresponding reasons.Modern physics is a difficult point in high school physics study.Therefore,in order to improve the efficiency of students' learning of this part of knowledge,create efficient classes and optimize teaching strategies,at the end of this paper,according to the above statistics and analysis,the author will put forward relevant teaching and learning problems and teaching suggestions.
