An Empirical Study On Visual Representation Based On IVR To Promote The Construction Of Physics Concepts In Junior Middle School

Immersive Virtual Reality(IVR)technology can present many abstract concepts and intangible physical quantities through visual forms to the audience and bring them an intuitive experience.The concept of physical buoyancy in junior high school is abstract and logical.These concepts also have a strong internal logical connection with each other.Because students are affected by the pre-concept,they have a bias of the relationship between buoyancy and the shape,weight,depth of the object,when proper guidance is not provided,it is hard for students to understand the concept of buoyancy intuitively.Based on this situation and the theories of concept construction learning and concept transformation,this study designs and develops an immersive buoyancy virtual experiment system using IVR technology and applies it to teaching practice to verify whether the immersive buoyancy virtual experiment system can effectively promote students’ understanding of the concept of buoyancy.Firstly,based on reading relevant references,the author understands the current status of the application of IVR in the field of education and the construction of physical concepts.Related research shows that IVR technology has certain advantages in promoting the construction of abstract concepts.However,these studies are relatively few.Secondly,misunderstanding of the pre-concept of buoyancy is identified and collected through questionnaires.The immersive buoyancy virtual experiment system is designed and developed based on the construction process of the buoyancy concept leveraging the advantages of VR technology.Finally,taking junior middle school students in Zhuji as the research audience,applying the quasi-experimental research method,the student’s academic achievement questionnaire and flow test were conducted,and interviews were conducted with teachers and students in experimental classes after the experiment,to explore the impact of the teaching intervention using the IVR virtual experiment system on the construction of physics concepts in junior middle school.The results of data sorting and analysis show that the visual representation of IVR can promote the correct construction of the concept of buoyancy,improve the teaching effect,and transfer to higher-order thinking;it can also improve the flow experience of learners;it can improve the efficiency of teaching and learning.The conclusions of this study can provide a new practical path and thinking enlightenment for the application of "VR + education" in the future,and can also provide a leading practical example for the deep integration of immersive virtual reality technology and classroom teaching.
