Research On The Application Of Project Based Learning In Junior Middle School Chemistry Experiment Teaching

Chemistry is a subject based on experiment,and experimental teaching plays an important role in chemistry teaching.However,through investigation and analysis,the author found that there are some practical problems in junior high school chemistry experiment teaching,such as teachers’ indoctrination experiment teaching,students’ fishing in troubled waters experiment operation,and experiment content separated from real life,which affect the cultivation of students’ chemistry subject quality and the formation of chemical experiment thinking ability.Based on the research of several teaching ideas and models,the author found that project-based learning can effectively improve the disadvantages of junior high school chemical experiment teaching.Based on this,this study scientifically expounds the theory of project-based learning and its application in junior high school chemistry experiment teaching.The main content of this study includes six chapters:The first chapter,the practical problems in junior high school chemistry experiment teaching.In this study,through the design of interview outline,12 chemistry teachers in six junior middle schools were interviewed in-depth.Through the interview,we found that there are more or less problems in junior high school chemistry experiment teaching at the teacher level,student level and teaching content level.By combing the interview content,the author sorted out the practical problems existing in junior middle school chemistry experiment teaching.The second chapter,the application value of project-based learning in junior high school chemistry experiment teaching.Project based learning is a student-centered learning mode,which is based on problem driven and produces project results through students’ cooperative learning.It fully respects students’ dominant position in the whole process.In chemical experiment teaching,project-based learning has important application value,which is reflected in its ability to highlight students’ perspective,change indoctrination experimental teaching mode,emphasize problem driving,improve students’ initiative in learning chemical experiment,create real situation,make experimental teaching more life-oriented,focus on chemical subject quality,and cultivate students’ experimental creativity.The third chapter is the construction of project-based teaching mode of junior high school chemistry experiment.Based on the construction of project-based teaching mode,this chapter discusses the application principles,basic elements and implementation strategies of project-based learning in chemical experiment teaching.Through scientific theory,the author combines the characteristics of project-based learning with the characteristics of junior high school chemical experiment teaching,and strives to create a chemical experiment teaching mode with students as the main body,real problems as the driving force,and project results as the embodiment.The fourth chapter is the case analysis of junior high school chemistry experiment teaching.In the process of case selection,the author first analyzes and interprets the junior high school chemistry textbooks of people’s education press and Shandong Education Press.According to the classification of experiments in the textbooks,the resources used and the relevant chemical knowledge,the author summarizes the experiments,and analyzes the key teaching experiments in junior high school.Based on this,combined with the analysis of project-based learning theory and mode,the paper selects and compares the relevant cases,selects the excellent cases,analyzes them in five dimensions,and summarizes the successful experience of the cases.The fifth chapter is the supporting system of project-based teaching in junior middle school chemistry experiment.Based on the literature review,interview data and case study,this study puts forward some suggestions on the application of project-based learning in junior high school chemical experiment teaching,focusing on the implementation of junior high school chemical experiment project-based teaching,including the construction of chemical experiment project-based teaching system,the development of resources and the cultivation of Teachers’ relevant ability,in order to open up a new era The reasonable project-based teaching mode of junior middle school chemistry experiment is issued to provide experience for the implementation of project-based teaching of junior middle school chemistry experiment.
