The Application Research Of PBL Teaching Mode In Junior Middle School Physics Teaching

The quality-oriented education implemented today puts forward clear requirements for the cultivation of students' scientific inquiry and physical experiment ability.It advocates to promote students' understanding of physics knowledge,cultivate their experimental research ability and strengthen their scientific literacy through student-centered diversified teaching.The author reviewed relevant literatures and found that PBL teaching mode(fully called Problem-based learning)can effectively achieve the above goals,but the application of this mode in physics teaching in junior high school is very rare.In addition,the Problem-based learning model has a significant effect on cultivating students' thinking ability and cooperative problem-solving ability,so this study can provide new ideas on how to improve the physics teaching effect in junior high school.The main work of this study is as follows:First,in view of students' fallibility is often the key to solve problems,the fallibility of physics students in grade two is summarized through interviews with students and senior teachers,as well as analysis of students' homework and exams.Secondly,put forward the PBL mode suitable for junior high school physics teaching,collect students' feedback in the process of PBL teaching,and summarize the advantages and disadvantages of the PBL teaching mode and Suggestions for its use.Thirdly,look up a lot of materials,and sort out the examples of PBL teaching mode of grade two physics according to the sequence of chapters in the textbook.Fourthly,the effectiveness and necessity of applying PBL teaching mode in junior middle school physics teaching were discussed through educational experimental research,score analysis,MSLQ scale analysis and other methods.The results show that the model plays an active role in improving students' physical performance,enhancing their learning motivation and adjusting their cognitive strategies.Through the interview,we know that the physics teachers of the internship school all agree that "questions can stimulate students to think",and think that the PBL teaching mode is worth carrying out.After the interview with the students,it is found that they are more interested in how to solve problems and have the ability to solve problemscooperatively.Students think that the process of solving problems can not only help them build the basic knowledge framework,but also help them master the scientific thinking and methods of solving problems,so as to better adapt to the development of society in the future.To sum up,PBL teaching mode plays a positive role in promoting the physics teaching effect in junior high school,which is worthy of being popularized and applied in physics education nationwide and even in the teaching of all subjects.
