Research On Physics Teaching In Senior High School Based On Virtual Experiment Platform

With the development of science and technology,the level of educational technology has also been significantly improved,most of the physical experiments can be simulated using virtual experiment platform.With the enhancement of chip computing power,more physical experiments can not only be completed by computers instead of people,but also ensure the repeatability of experiments and the accuracy of results.It can be said that the era of digital virtual experiment has come to aerospace orbit measurement and wind tunnel experiment and small circuit virtual presentation.The middle school physics virtual experiment platform arises at the historic moment and serves the physics teaching practice under such a background.It not only reflects the advanced nature of the physics discipline,but also provides great convenience for the physics experiment teaching,and shows the experimental principles and laws in a more vivid and intuitive form.Education needs to keep pace with The Times.Virtual experiment is the extension of traditional experiment and the direction of experimental teaching in the future.With the continuous innovation and integration of science and technology and education,virtual experiment platform must be constantly improved to meet the needs of education.In 2003,the physics curriculum standard for senior high schools issued by the Ministry of education clearly stated that"information technology should enter the physics laboratory".The physics curriculum standard for senior high schools(2017 Edition)pointed out that we should actively explore the deep integration of information technology and physics teaching,and actively develop and utilize digital media curriculum resources.As an important form of physics teaching,if we can catch the fast train of digital multimedia,it is bound to provide convenience for students to master scientific knowledge and develop scientific thinking.The outline of the national medium and long term education reform and development plan(2010-2020)clearly states:"strengthen the development and application of high-quality education resources,strengthen the construction of online teaching resource system,and develop online learning courses.Establish digital libraries and virtual laboratories.During the new coronavirus epidemic,under the background of" no classes,no classes,no schools",Relying on the offline experimental operation teaching activities,it was once in a stagnant state.The more advanced dis(digital information system)is also difficult to show its strength in online teaching.Its "convenience","intelligence" and other characteristics are separated from the entity platform and are also stretched.A series of problems encountered in the traditional offline experimental form show that an educational reform of experimental virtualization is imminent.Therefore,in order to adapt to multi scene experimental teaching and make up for the limitations of online experimental teaching,the construction of virtual middle school physics experiment platform has research needs and practical significance.Firstly,this paper defines the concepts related to physical virtual experiment.Secondly,from the virtual experiment teaching mode strategy,virtual experimental physics(curriculum)teaching design,virtual experiment application survey of literature research,to investigate the application of virtual experiment in middle school physics and the factors affecting the use of virtual experiment.Based on the actual situation of the literature survey,this study explored the influencing factors of the implementation of virtual experimental teaching from the three levels of platform,teachers and students,and analyzed the obstacles to the implementation of virtual experimental physics teaching,including the platform's "momentum" limitation,the lack of "potential energy" of teachers and the lack of "kinetic energy" of students.In view of the specific difficulties in the implementation of virtual experiment assisted teaching,this study puts forward the principle of "eight characteristics and four combinations"in the teaching design of Physics Virtual Experiment in senior high school,including the combination of functionality and practicability;The combination of virtuality and reality;Combination of scientificity and ease of use;Combining interest with education,the experiment is classified into two categories:Inquiry "reality" and demonstration "ideal" from"function" and "form".On this basis,the process criteria of virtual experiment applied to instructional design and the respective instructional design processes of the two types of experiments are put forward.Finally,based on the nobook platform,this study takes"exploring the law of conservation of momentum" and "the movement of charged particles in a uniform magnetic field" as examples to carry out teaching design and practical analysis,so as to provide reference for the efficient utilization of the Physics Virtual Experiment Platform in middle school,so as to help deal with the dilemma that the virtual experiment is not well integrated into the physics classroom teaching at this stage.
