Research On Middle School Physics Experimental Teaching Based On PBL Teaching Model

The discipline of physics should cultivate students’ core physical literacy,continuously emphasize their subjectivity,cultivate their understanding,thinking,and hands-on abilities,return the classroom to students,and make them the masters of the classroom.Experiments are the "soul" of junior high school physics,and as an important component of junior high school physics,physics experiments have significant practical significance in cultivating students’ thinking logic and core literacy.However,in actual teaching,due to various factors,teachers often use demonstration experiments and playing experimental videos to teach junior high school physics experiments.The PBL teaching model is a "problem based" teaching model that actively participates in the classroom through problem-solving,focusing on the classroom.The classroom is more compact and efficient,and students’ thinking is more flexible,which is conducive to cultivating students’ knowledge transfer ability.This article is a research on junior high school physics experimental teaching based on the PBL teaching model.By analyzing the relevant literature on PBL teaching mode and junior high school physics experimental teaching,explore the theoretical and practical significance of PBL teaching mode in junior high school physics experimental teaching;Understand the current situation of junior high school physics experimental teaching and PBL teaching mode through teacher-student surveys;Analyze the internal connection and feasibility of PBL teaching mode and junior high school physics experimental teaching,and design a reasonable PBL experimental teaching process;Develop teaching design cases based on PBL teaching mode,and use experimental research methods to conduct teaching practice on corresponding classes.After the practice,a two-way breakdown table was used to analyze the corresponding exercise scores,and after class interviews with teachers and students were conducted to test the effectiveness of PBL based junior high school physics experimental teaching practice.Through the above research process,the research conclusion is drawn:based on the PBL teaching model in junior high school physics experimental teaching,students focus on problem-solving,and the discipline and safety of experimental courses are guaranteed,which to some extent eliminates teachers’ concerns that the discipline and safety of experimental courses cannot be guaranteed;By adopting PBL teaching mode,students have higher learning efficiency and better knowledge transfer ability when facing increasingly flexible middle school entrance examination questions.The research on junior high school physics experimental teaching based on PBL teaching mode provides a teaching mode reference for junior high school physics experimental teaching.
