Research On The Application Of Micro-project Learning In Chemistry Experiment Teaching In Junior Middle School

Chemistry is a science based on experiment,and experiment plays an irreplaceable role in the development of chemistry.In the new curriculum reform,the importance of experimental teaching is increasing day by day,and it has become an important teaching idea to promote the comprehensive ability of students through experimental teaching.The traditional experimental teaching mode has been unable to fulfill the requirements of the cultivation of students' comprehensive ability.Micro-project learning mode takes students as the main body and stimulates students' interest in learning by allowing them to solve problems in real situation,thereby realizing the construction of knowledge and the improvement of comprehensive ability.Therefore,this paper introduces micro-project learning into chemistry experiment teaching in junior high school,and analyzes the feasibility,specific implementation steps and effects of micro-project learning on chemistry experiment teaching in junior high school.This paper studies the application of micro-project learning in chemistry experiment teaching in junior middle school from both theoretical and empirical aspects.The methods used mainly include literature method,experimental investigation method and questionnaire survey method in this paper.First of all,the research status of micro-project learning at home and abroad is understood by combing the relevant literature,and the purpose and significance of this study,as well as the ideas and methods adopted in this study are determined.Then it defines the concepts of chemistry experiment teaching,project-based learning and micro-project learning,and puts forward the theoretical basis of micro-project learning.On the basis of previous studies,the design principles,general process and matters needing attention in the design of micro-project learning in chemistry experiment teaching are determined in junior middle school.Based on the previous theoretical research,it designs the application case of micro-project learning in chemistry experiment teaching in junior high school.Two parallel classes in the third grade of a junior high school in Lanzhou were used as the controlled class and the experimental class to carry out experimental teaching research.The controlled class adopts the traditional teaching mode,and the experimental class adopts the micro-project learning mode.Then,it tests the application effect and acceptance degree of micro-project in chemistry experimental teaching in junior middle school by test paper and questionnaire,and uses SPSS23 to analyze data.The results show that the application of micro-project learning can significantly improve students'sense of participation and interest in chemistry learning,and can promote students'hands-on skills,problem-solving abilities,and cooperation and communication skills,And to some extent helps to improve students ' chemistry performance.To sum up,it is feasible to apply micro-project learning to chemistry experimental teaching in junior high school.This study provides some reference and direction for further development of micro-project learning in chemistry experiment teaching in junior middle school in the future.
