Application Of Micro-teaching Skills In Interesting Chemistry Experiment Teaching

Chemistry is an experiment-based subject.The application of Microteaching skills in interesting chemistry experiment teaching can not only stimulate students' enthusiasm for studying,but also effectively mobilize students' enthusiasm for learning.At the same time,it can help teachers improve teaching links and effects.On the basis of literature research,this paper explores the application of Microteaching skills in interesting chemistry experiment teaching from three aspects:experimental optimization design,Microteaching skills teaching design,and case practice teaching design.Feedback the teaching effect through questionnaire survey,achievement analysis and teacher interview.The research contents of this paper are as follows:First of all,This paper investigates the implementation of interesting chemistry experiments and Microteaching skills at home and abroad,and analyze the feasibility of applying Microteaching skills in interesting chemistry experiment teaching,puts forward research ideas,and elaborate the research significance of this topic under the new curriculum reform.Second,based on the definition of the core concepts of "Microteaching skills" and " interesting chemistry experiment ",the research is carried out with the theoretical support of "constructivist learning theory","humanist theory" and "disciplinary core literacy",Summarizes the basis for design optimization of interesting chemistry experiments and the practical basis for applying Microteaching skills in interesting chemistry experiments.Then,based on the principles of science,fun and feasibility,four interesting chemical experiments are designed and optimized,and integrated the Microteaching skills into the teaching design.After that,two of the experiments were selected for practical teaching of classroom and activity exploration.Finally,through the questionnaire survey and interview with the students and teachers participating in the case teaching in Ningxia A Middle School,as well as the analysis of the examination paper,the paper summarizes the effect evaluation of the application of interesting chemistry experiment in microteaching skills practice teaching.The research shows that after the teaching practice,the experimental class has higher scores and more interested in chemistry than the control class.The combined application of Microteaching skills and interesting chemical experiments is scientific and practical,which can enrich the teaching model,improve learning efficiency,and provide reference for middle school teaching practice.
