Development And Application Of Augmented Reality Teaching Software

The characteristics of chemistry determine the difficulty of learning chemistry in the cognitive span between macro and micro.To reduce the difficulty of learning,need to provide students with physical or micro models to help students build a cognitive "bridge" between macro and micro.Augmented reality(AR)technology refers to the virtual information that does not exist in a certain region of the real world,based on a certain medium and then superimposed on the real world,which is perceived by the human senses.With the development of science and technology,AR technology is becoming popular and widely used in education and other fields.At the end of 2018,the Ministry of Industry and Information Technology thought that "VR/AR education"should be applied as a key industry.This paper takes the design and development of an organic chemical augmented reality software "OCAR",as an example,systematically discusses how to develop augmented reality software,and initially detennines the evaluation index of AR teaching software.The theoretical foundations of augmented reality technology applied to teaching include constructivist theory,situational learning theory,audiovisual education theory and flow theory.Achieving augmented reality requires tracking the three key technologies of registration,human-computer interaction and display technology.Augmented reality is widely used in various fields with its unique technical advantages,focusing on its application in the education industry.It also compares several domestic and foreign chemical augmented reality technology applications from the aspects of software content and appearance,and finds that augmented reality technology in organic chemistry is rarely involved,and then determines the specific content of this research.Taking the development of "OCAR" software as an example,the specific steps of AR software development are decomposed in detail,and finally the general steps of Augmented Reality teaching software development are summarized:teaching content and target analysis,development environment configuration,material preparation and production,and interactive functions.Idea and visual design,package release APK.It can be seen that the biggest difficulty in developing augmented reality software is the modeling of virtual objects and the scripting of various virtual buttons,scene conversion,animation playback,and the like.Then the developed "OCAR" software is applied to the specific teaching,and the four evaluation indicators of the augmented reality teaching aid software are initially determined:APP texture/beauty,function design,learning function and learning experience.There are two or three questions under each level of indicators,using the Likert 5 subscale to determine the student’s attitude towards the software.Questionnaire interviews were also conducted with teachers to investigate teachers’ understanding and attitudes on augmented reality technology,and what specific issues should be considered when applying AR to chemistry teaching.Based on the development of the organic chemical augmented reality teaching software"OCAR",this paper summarizes a clear design idea and design process,and provides some effective information reference for designers in the field of augmented reality education APP design.The results show that the development of augmented reality software must specifically consider the needs and applicability of the teaching content and objectives,and choose appropriate and diverse interaction methods.The application of augmented reality technology to chemistry can help students learn the spatial structure of organic matter,make micro-knowledge "visualization",and students can actively participate in the teaching process.Students think that OCAR software is generally good,the texture/beauty,learning function and learning experience of the APP is better,but the interactive function of the software is not very good In the future,it is necessary to upgrade the organic chemistry content of more content and the interaction mode of the reaction mechanism.
