Research On The Application Of Virtual Experiment In Chemistry Teaching In Senior Middle School

With the development of information technology,teaching methods have also been continuously reformed and many information technologies are used in education.With the development of information technology,teaching methods have also been continuously reformed.Many information technologies are used in education.As a new information technology that has been developed in recent years,virtual laboratories have been applied to experimental teaching by some colleges and universities.In the field of education,people are paying more and more attention to virtual laboratories.However,there are other problems that need to be further studied.Is it feasible to use virtual experiments in high school chemistry? Which experimental content is suitable for using virtual experiments? How to better use virtual experiments in high school chemistry? The above three questions are the focus of this paper.In addition,I hope that this study can promote the integration of virtual experiments and high school chemistry teaching.In my study,the present situation of the research on the application of virtual experiment to the chemistry teaching in middle school at home and abroad is summarized and analyzed.Then through the method of questionnaires to investigate the hardware facilities of the middle school,teachers and students' views about the virtual chemistry experiment and carry out the feasibility analysis of this study.According to the characteristics of virtual experiment,the content suitable for virtual experiment teaching is designed and the teaching design is written in combination with relevant teaching theories and learning theories.Finally,the classroom teaching practice is carried out by using NOBOOK virtual laboratory.Using the method of comparative experiment to carry out the investigation.For the content that can't be used for real experiments,the experimental group adopts virtual experiment teaching,and for the control group adopts video teaching.The teaching results are tested in the form of questionnaires and tests.Through the questionnaire,it can be found that the teaching method of applying virtual experiment in middle school chemistry teaching is feasible.Most students recognize the teaching method that using virtual experiments in chemistry classes,pre-class preparation and after-school review.They believe that virtual chemistry labs can increase their interest in chemistry learning and help them learn new chemistryknowledge.The chemical test results of the two different methods of virtual experiment and video watching are obviously different.The survey results show that compared with video experiment teaching,virtual experiment teaching can strengthen students' mastery of chemical knowledge.For the content that can't be used for real experiments,using virtual experiment as a supplementary teaching method is a feasible and effective.
