Research On The Development And Application Of Junior Middle School Chemistry Learning Software Based On Augmented Reality Technology

The advancement of science and technology has made tremendous contributions to education.More and more emerging technologies are used in education and teaching to solve the difficulties in teaching and provide a variety of learning methods for students'learning.Virtual reality,augmented reality,and artificial intelligence,as new technologies in rapid development,not only contribute to industries such as industry,military,medical,etc.,but are also increasingly used in teaching because of their unique advantages,and national policies are also active.Promote technology to promote teaching and provide a guarantee for technology to be applied to teaching.Middle school chemistry as a science subject,the most important learning process is the understanding of the abstract spatial structure and the observation of chemical experiments.In the early stage of exposure to chemistry learning,junior high school students often influence their later learning because of their lack of abstract ability.The lack of experimental equipment and the setting of experimental courses have also led to less manipulation of chemical experiments by students,which has affected students'scientific inquiry into chemistry.The emergence of augmented reality technology makes up for the shortcomings of chemistry learning.It can turn abstract concepts into realistic models for students to understand.It can also design AR chemistry experiments to reduce environmental pollution and provide visual chemical reactions for students to observe,so that students can go anywhere,anytime.Conduct scientific experiments and explore.Therefore,the use of augmented reality technology to assist chemistry learning can improve the effect of chemistry learning to a certain extent.Through the preliminary demand survey,this study found that the study of middle school chemistry now has fewer experimental courses,students can not grasp the difficulties of chemistry learning,students' understanding of abstract concepts,and their interest and effect on students' chemistry learning.Both have a big impact.Therefore,the design and development of augmented reality chemistry learning software for junior high school students' chemistry learning will improve this dilemma.The specific research process of this paper is as follows:First of all,this study combs the literature of augmented reality technology,analyzes the way augmented reality technology is applied to education,and provides reference for further research.Secondly,the related theories are collated and analyzed,the advantages of combining augmented reality technology with these theories are introduced,It also introduces the key technologies and platforms involved in this research,in the mean time provides a theoretical basis for the design and development of software.After that,through the distribution of the recycling demand analysis questionnaire,the functional modules of the software were designed and the ideas of software development were designed.Then,select the appropriate software platform 3Ds max and Unity 3D to develop and test the software and further improve the software.Finally,for the software,a questionnaire was designed to investigate the students' learning effectiveness and software acceptance using the software,and a controlled experiment was designed to test students' use of the augmented reality chemistry learning software for learning and traditional learning methods.The data including the students' interest in learning,learning satisfaction and knowledge and skills were investigated,and the effect of using the software for learning was proved.A software acceptance survey was also conducted for the experimental group.The conclusions of this study are as follows:The use of the augmented reality chemistry learning software for learning can improve students' interest in learning;the student's learning satisfaction is also high,indicating that the software can be used as a learning tool for students;in the dimension of knowledge and skills mastery Students using Augmented Reality chemistry software to learn and use textbooks for learning have no significant differences,indicating that students can use the software to learn when they are not qualified to conduct chemical experiment exploration;in terms of software acceptance,students' perceived usefulness and perception in software The average scores for ease of use and perceived satisfaction are high,indicating that students can accept the software for learning.
