| With the continuous reform of physics curriculum,more and more advocates the idea that physics comes from life and serves life,which is reflected in the research on original physics problems.Starting from unprocessed natural phenomena and daily practical problems,the original physical problems gradually guide students to learn through modeling and mathematical calculation,which can not only promote the development of students’ scientific literacy,but also arouse their interest in learning.This paper studies the practice teaching of primary physics problems in junior middle school,including five points.The introduction describes in detail the background of the research and the research situation of the original physical problems at home and abroad,and states the purpose and significance of the research.Second,the theoretical basis,gives the definition of the original physics problem and the original physics problem in junior high school,and summarizes the theoretical basis of the research from the perspective of pedagogy and the original physics theory.Iii.Investigation of the current situation,investigating the teaching situation of primary physics problems in grade two and grade three of Urumqi no.50 middle school.Knowing that the students have a shallow understanding of the original physics problems,they do not know how to start when solving the original physics problems,but they are very interested in the original physics problems.This paper interviewed seven physics teachers in the middle school of 50 for their understanding of the teaching of original physics problems,and found that the teachers’ teaching of original physics problems was not adequate.On the basis of the survey results,some Suggestions are given to carry out physics teaching on the original problem in the later period.Fourth practice teaching,the statistics of the original physical problems in the first four chapters of the eighth grade.On the basis of unit test of mechanical movement,class 2 and class 7 of grade 8 were selected as the practice objects.The practice teaching of two chapters of material state change and light phenomenon was conducted to stimulate students’ interest in learning,train their language expression ability to explain original physical problems,and promote the formation of students’ scientific literacy.In the later stage,the post-test of original physical problems was carried out on the practical objects.Based on the students’ answers,the scores of different sections in the experimental class and the control class were compared,and the students’ ability to solve practical problems was given after the teaching of original physical problems.Five summary,the research achievements,innovation and shortcomings of the existing summary.The research shows that there are some problems in the teaching of primary physics problems in junior middle school,such as the low cognitive level of students to the original physics problems and the weak ability of students to solve the original physics problems.Specifically,the students were not clear when they did not explain the meaning and examples of the original physics problems;when they encountered the original physics problems and needed to solve them,the students said that they did not know what the knowledge under investigation was;and they also said that it was difficult to explain the original physics problems in physical language.After a period of teaching time to implement original physics problems,it can be seen from the classroom feedback and post-test results that students’ ability to analyze physical phenomena and explain original physics problems has been improved,which can effectively stimulate junior middle school students’ interest in learning physics and promote the efficiency of teachers’ teaching and students’ learning. |
