Design And Implementation Of Multi-modal Interactive Virtual Laboratory For Junior High School Physics

With the continuous development of science and technology such as multimedia technology,network technology and virtual reality,modern education has become more information-based and digital.Various new technologies continue to cross and integrate with various disciplines,and the form of education has also changed in the information age.How to apply new technologies to the teaching of various disciplines has become a hot topic in the current research of educational modernization.In the exploration of various disciplines,experimental teaching research has attracted attention,and physical experimental teaching is one of the key research fields.Due to the limited facilities in some schools,it is difficult to carry out standardized physical experiment teaching.In the process of teaching experiment,there is a lack of innovation,and the teaching method is relatively backward.The teaching method of virtual laboratory is also mainly based on plane virtual experiment,with less interaction,which cannot meet the experimental needs of students and affect the teaching effect.In view of the above problems,this paper takes multimodal interaction as the core technology,takes the friction exploration and nuclear energy experiment in junior middle school physics experiment as the content elements,combines the characteristics of multimodal interaction and virtual experiment,uses Unity platform and Oculus Quest2 equipment to design and develop a multimodal interaction virtual laboratory for junior middle school physics.The specific research content of this paper includes six parts.The first chapter mainly introduces the background of this study,analyzes the problems existing in the physics experiment in junior high school,summarizes the specific research content,research objectives and significance,and determines the research methods.The second chapter mainly introduces the related concepts involved in the study,analyzes the research status of multimodal interaction and virtual laboratory at home and abroad,and introduces the basic theory supporting the research content.The third chapter mainly focuses on the preliminary requirements and functional design of the multimodal interactive virtual laboratory for junior middle school physics.The questionnaire and interview outline are distributed and recycled in a middle school in Nanchang.The questionnaire and outline are summarized and analyzed.The experimental content and application strategy of the multimodal interactive virtual laboratory are determined.According to the design indicators and design principles,the design of functional modules and demand logic is completed.The fourth chapter mainly introduces the development process of multi-modal interactive virtual laboratory for junior high school physics,including three main steps :development environment construction,virtual scene construction and algorithm function realization.The fifth chapter mainly conducts experimental research and analysis on the teaching effect of multi-modal interactive virtual laboratory for junior high school physics,selects two classes of a middle school in Nanchang for teaching application,and analyzes the application effect and summarizes the conclusion according to the data and questionnaires before and after the test.The sixth chapter mainly summarizes and prospects the main research work and innovation points,analyzes the shortcomings,and provides suggestions for future research on physical virtual laboratory.The multi-modal interactive virtual laboratory for junior middle school physics is based on multi-modal interaction technology.Starting from the three sensory experiences of vision,hearing and force perception,it designs and implements a rich interactive mode,which attracts students ’ interest in learning,has a positive impact on students ’ academic performance and learning effect.It also provides a new type of physics experiment teaching method for teachers,enriches the classroom teaching mode to a certain extent,and provides reference for junior middle school physics experiment teaching.
