Research On The Design And Application Of Immersive VR Micro-classes

Under the background of the continuous development of information technology,educational ideas,methods and technologies are constantly updated.Situational teaching method,as a teaching method in line with the knowledge generation view of constructivism,has shown great advantages in specific knowledge teaching.As a new type of teaching media technology,virtual reality technology has obvious advantages in sensory simulation,scene construction and human-computer interaction,which provides great technical support for situational teaching.2017,as the first year of virtual reality,is also the symbol of the gradual maturity of virtual reality.After two years of technological development,the dividend period of virtual reality technology has come.How to seize the opportunity,excavate the resources treasure of virtual reality technology in the field of education,and promote education from the audio-visual media era to the all-media era is the task of the researchers of virtual reality applied in technology education.This paper mainly completes the following work:(1)Through content analysis,the feasibility of applying virtual reality technology to micro-lecture is analyzed.Through summing up,this paper makes a comparative analysis of the physical environment and learner support of five types of micro-lecture,and concludes that immersive and immersive and unicast VR micro-lecture have very high application value in specific knowledge teaching.Through the analysis of the popular way of learning in the social context,it is concluded that the immersive and immersive and unicast VR micro-lecture based on mobile terminal conforms to the learning concept of the ubiquitous learning era.(2)Through summing up,the influence factors of immersion VR micro-course on learning are analyzed from the perspective of 31 characteristics of VR technology.Based on the author's design and development experience,this paper summarizes the special design princples and development principles of immersion VR micro-lecture.(3)Using the model method,the system development model of the immersive and immersive and unicast VR micro-lecture is designed,and the phases and tasks of the production process of each micro-lecture are explained in detail by the two branches of the immersive and unicast VR micro-lecture and the immersive and unicast VR micro-lecture.In the final stage of the system development model,self-report measurement and customer satisfaction are used to interview and evaluate the quality of micro-lecture.The overall quality level of the two micro-lecture is qualified.At the same time,some problems are found.According to these problems,VR micro-lecture are further optimized.(4)Using the methods of experiment and interview,taking the presentation of knowledge as the independent variable,and taking the students' positive emotion,knowledge retention rate and cognitive load as dependent variables,this paper studies the influence of immersive and immersive and unicast VR micro-lecture on students'learning.The experimental research shows that immersive and immersive and unicast VR micro-lecture has a very high application value in students' emotional guidance and knowledge maintenance.At the same time,compared with the learning mode of video watching,the virtual reality experience mode based on "mobile phone+VR glasses"will increase students' cognitive load.After that,the results of the experiment are analyzed and discussed,and the limitations of the experiment are analyzed.At the same time,some assumptions and prospects are made for the experimental research of VR micro-lecture.
