Researc On The Teaching Model Of Chemical Experiment Based On VR Technology

With the continuous development of Internet and computer technology and the increasing popularity of mobile terminal equipment,new teaching media are constantly emerging.After the multimedia,a new teaching media,virtual reality technology has emerged in the field of education.The purpose of this paper is to apply VR technology to the chemistry experiment class in middle school to improve the effect of the chemistry experiment class,especially to cultivate the ability of the learners' experimental operation and the construction of the chemical experiment knowledge,to explore the teaching mode suitable for the experimental teaching of VR,and to solve some problems in the chemistry experiment teaching.Through the application of VR technology in the chemical experiment,we can improve students' comprehensive ability and scientific literacy,cultivate students' rigorous research attitude and scientific experimental teaching research ability,cultivate and train the ability of experimental and experimental teaching,cultivate the students' spirit and innovation ability,and establish the concept of green chemistry,and complete the realization of the concept of green chemistry.From laboratory research to experimental teaching research.The research methods in this paper are literature analysis,interview and case analysis.In this paper,the virtual reality technology is used as a new educational technology,and it is applied to the study of chemical experiment in middle school,and the teaching mode suitable for VR experiment is summed up through the practice of education.This VR experimental teaching mode breaks through the shackles of traditional teaching,opens up new space for teaching methods,and forms a new platform for non practical rationalization and innovation.Under the teaching mode of VR experiment,students expand their horizons,break through the limited understanding of space,and enrich the learners' perception of the world.The first chapter expounds the research background of the subject and the status of the research at home and abroad,clarifies the shortcomings of the traditional teaching methods and the importance of the application of VR technology in education and teaching.On this basis,it explains the purpose and significance of the research,and makes clear the research methods.The second chapter focuses on the concept,characteristics and classification of VR technology.Through the analysis of the characteristics of VR technology,it discusses its theoretical support in the application design of chemical experiment teaching,including the theory of subjectivity education,constructivism theory,information technology and the theory of deep level integration of the curriculum.The third chapter mainly expounds the design ideas and teaching mode of VR experiment.This part classifies the chemical experiments in middle schools and divides them into three categories: detection type,inquiry type and analogue type.According to the principle of experimental design and the support of theory,different kinds of VR experiments are designed,and suggestions are given,and the teaching mode suitable for each kind of chemistry experiment is found through teaching practice.The fourth chapter turns to practice.Through interview method,the effect and significance of teachers and students on the effect of VR experiment are summarized and analyzed in the process of educational practice.The fifth chapter summarizes the achievements of this research,summarizes the achievements of the paper,reflects the shortcomings in the research,and puts forward some follow-up prospects.
