Research On The Design And Application Of Junior Middle School Chemistry Virtual Experiment Teaching Resources Based On Unity3D

Virtual reality technology,that is,the integration of virtual and real technology.Because of its unique immersion,interactivity and other characteristics,it is gradually applied in more and more fields,and gradually becomes a new field of science and technology.With the continuous development of its technology,it is also gradually moving towards primary and secondary school classroom.Chemistry is a subject based on experiment.All aspects of life are inseparable from chemistry.In the actual teaching process of junior middle school chemistry classroom,in order to enable students to build a macro and micro chemistry system and stimulate students’ interest in learning,experiment based chemistry classroom teaching is very necessary.However,from the current junior middle school chemistry classroom teaching mode,affected by the pressure of entering a higher school and the amount of class hours,the experimental display and student participation in chemistry classroom teaching have not been paid attention to,which makes the junior middle school chemistry classroom teaching can not achieve the ideal teaching effect because of the lack of students’ operation of chemical experiments,so it can not get an in-depth understanding of the essence of chemistry and the principle of reaction.Another part of the reason is that glass instruments are mainly used in chemical experiments,many of which need to use alcohol lamps,which has certain safety problems.Therefore,it is often difficult for most teachers to let the whole class participate in chemical experiments in a large area in their actual teaching process.However,this kind of problem can be well solved through virtual reality technology.Through the development of virtual experiment,every student can participate,practice in different time periods,and cultivate their interest and exploration in chemistry.Therefore,the application of virtual reality technology to junior middle school chemistry teaching can cause different changes.Based on this,based on the unity3 d development platform and taking the ninth grade chemistry course of junior middle school "making oxygen" of people’s education edition as an example,this study designed and developed a virtual experiment-making oxygen from potassium permanganate,and carried out the design and Application Research of teaching resources.Using the method of literature research,this paper analyzes the research status of virtual experiment at home and abroad.Before the development of the virtual experiment,a questionnaire survey was conducted on the teachers of a key junior middle school in Nanchang,Jiangxi Province and the students in grade three,the corresponding teaching plan was formulated,and the virtual experiment supporting this class was developed and designed.After the development of virtual experiment,it is actively applied to teaching,and compared between the experimental class and the control class.After practical application,it is analyzed from three aspects: learning interest and attitude,the use of virtual experiment system and the mastery of knowledge and skills through test results and questionnaire survey,so as to obtain the impact of virtual experiment platform on students,and conduct general data processing and analysis through the interview and survey of teachers.The analysis shows that the integration of virtual experiment into junior middle school classroom can improve the problem that many students do not know enough about the essence of experiment because they can’t go to the laboratory.Virtual experiment can improve students’ enthusiasm and their understanding of experiment related knowledge.The development of the virtual experiment is the effective integration of information technology and educational theory,and provides reference for the development of chemistry teaching resources in junior middle school.
