| Experimental teaching is a crucial part of biology teaching in middle school,but some experiments are not suitable for middle school biology experiment teaching because of the high cost,long operation period and obvious effect.Virtual experiment has the advantages of interactivity,immersion,simulation,free from time and space constraints,and thus become one of the ways to solve this problem.However,there are few studies on how virtual experiments can be applied to secondary school teaching,especially secondary school biology experiment teaching.In this paper,through the literature research method,survey method and experimental research method,the application of virtual experiment assistant secondary school biological experiment teaching is analyzed.This paper mainly consists of the following parts:Chapter 1,Introduction.This paper introduces the research background of biology experiment teaching and the rapid development of virtual experiment in our country,and then elaborates the purpose,meaning,content,thought and method of the research.Chapter 2,theoretical basis and research status quo.On the basis of reading a lot of literature,the relevant theory of virtual experiment and its research status at home and abroad are expounded.Chapter 3,Analysis of the way of virtual experiment assisted experiment teaching.Based on the existing problems of biology experiment teaching in middle school,based on the analysis of the experimental content of virtual experiment assisted teaching,this paper analyzes the way of virtual experiment to assist the biology experiment teaching in middle school and summarizes the different classes of theoretical and experimental courses Corresponding teaching process."Virtual experiment assisted demonstration experiment" approach for the virtual experiment instead of teachers to demonstrate experimental teaching;"virtual experiment to help students experiment" approach for the combination of virtual experiments and real experiments,"the first after the virtual" or"first virtual reality";"Virtual experiment to assist the theoretical course related experiments" approach for the virtual experiment instead of teachers orally to explain the experiment or multimedia demonstration experiment.Chapters 4 to 6,case design and implementation.Based on the virtual experiment,the different methods of biology experiment teaching in middle school are studied.According to the requirements of curriculum standard and the specific learning situation,the teaching design,the practice of classroom teaching and the knowledge of students are written in different ways.Quiz and Virtual Experiment Application Effect Questionnaire.According to the situation of classroom teaching,pen and paper test,the questionnaire survey of students in three aspects of virtual experiment assisted secondary school biology experimental teaching application analysis.The results show that:1.The virtual experiment can help students to master the experimental content and related skills,enhance the students' interest in learning and improve the effect of experimental teaching.2.The combination of virtual experiment and real experiment teaching method More effective than other methods;3.Students apply to the teaching of virtual experiments that recognition.Chapter 7,Conclusion.First of all,the results of this study and the shortcomings of the summary.And then put forward some suggestions and countermeasures on how to effectively use the virtual experiment to assist the biology experiment teaching in middle school:1.Fully understand the important role of experimental teaching in biology teaching in middle school and improve the importance of biology experiment course;2.correctly understand the virtual experiment The auxiliary function of biology experiment teaching in middle school;3.Improve the information quality of teachers and students;4.improve the quality of biology virtual experiment in secondary school research and development;5.increase the virtual experiment in secondary school biology teaching preview and review;6.Increase the intensity of student groups to discuss the exchange of students to develop scientific research ability;7.According to the specific textbook experimental teaching content,selectively in the classroom using virtual experiment assisted teaching.Finally,the future development of this study is forecasted. |
