Development Of Interactive Exhibits Based On Electromagnetic Force And Its Application In Exhibition Education Activities

Since the plan for the implementation of the national action plan for scientific literacy(2016-2020)was promulgated in 2016,more and more attention has been paid to the popularization of scientific knowledge and scientific education in China.Science and Technology Museum is an important place for the popularization of scientific knowledge,and popular science exhibits are the core components of science and Technology Museum,which play an important role in the popularization of scientific knowledge.In recent years,China's investment in the construction of science and technology museums has been increasing,and the exhibits in science and technology museums are gradually colorful,both static and dynamic,both focusing on observation and visit,and also based on personal experience.In addition to visitors' experience,exhibits in science and Technology Museum are usually used in the implementation of exhibition and teaching activities.Through exhibition and education activities,on the one hand,visitors have a deeper understanding of the scientific principles behind the exhibits,on the other hand,through personal experience and the production of exhibits,they have also improved their hands-on ability and exploration ability.But most of the scientific exhibits about electromagnetic force are focused on the angle of electromagnetic force produced by the magnetic field to the electrified wire or conductor at present,and few of them focus on the angle of magnetic force produced by the magnetic field to the electrified fluid.In addition,most of the science and technology museums have the phenomenon of "attaching importance to exhibition and belittling teaching".Even if the exhibition and teaching activities are held,most of them are focused on traditional themes such as astronomy and robotics,lacking certain innovation,and also belittle the hands-on exploration process of participants in the exhibition and teaching activities.Therefore,this paper combines the current situation of science and Technology Museum and science and technology activities.On the one hand,it designs three exhibits of flowing liquid,magnetic boat and magnetic fountain to innovate the exhibits of electromagnetic force in the science and Technology Museum.On the other hand,it designs the exhibition and teaching activity course of inquiry type to apply the above exhibits in the exhibition and teaching activities.Through the analysis of the results of questionnaire survey,it is found that the exhibition and teaching activities have been carried out before The achievement of the three-dimensional goals of most students in the program is still ideal,and this exhibition teaching activity has reached the recognition of most students.The thesis is divided into five parts.The first part: expounds the research background,research significance,exhibition design and research status of exhibition and teaching activities,as well as the definition of related concepts in the paper and introduces the main research methods.The second part: introduces the principles of scientificity,integration,innovation,interaction and safety,as well as the principles behind the exhibits from the micro and macro perspectives.The third part: expounds various factors to be considered in the process from the beginning of the design to the completion of the design of the exhibits.It mainly includes the design principles of the electromagnetic force series interactive exhibits,the preliminary ideas for the exhibits after consulting the materials and field investigation,and the precautions for selecting the materials after the preliminary design of the exhibits,the preliminary design of the exhibits does not meet the preset standards,so we need to improve the exhibits,and finally design the electromagnetic force series interactive exhibits that meet the requirements.The fourth part: expound the theoretical basis and significance of the development of exhibition and teaching activities.Discusses the main theoretical basis for designing the contents,objectives and teaching modes of exhibition teaching activities,and compares the exhibition teaching activities with high school physics experiment courses,highlighting the exploratory characteristics of exhibition teaching activities.The fifth part: introduce the implementation process of exhibition and teaching activities.The students of grade 2 from Jinan No.1 senior school were selected as the objects of the activity,and the exhibits designed in the third part were cited in the exhibition teaching activities.The achievement of the three-dimensional goals and the satisfaction degree of the activity were analyzed by questionnaire.
