Through a large amount of literature research,this paper summarizes the current situation of the application of augmented reality technology to middle school teaching at home and abroad,and puts forward the teaching mode of enhancing the practical technology inquiry in the current chemistry teaching.The research contents include the design and development of augmented reality chemical software,the design of teaching plan,the classroom practice of research contents,etc.,and the applicability of augmented reality chemistry teaching software in middle school chemistry classroom teaching is analyzed through investigation and research results.Through the guidance design of multiple intelligence theory,cognitive theory,constructivism theory and audio-visual education theory,ChemAR is developed.This software combines augmented reality technology with mobile communication equipment to realize the visualization of abstract concepts,micro-knowledge and spatial structure,and creates a virtual reality teaching situation that seamlessly interacts with reality,which maximizes the enthusiasm of learners and helps learners develop multi-dimensional space,which is characterized by simple operation and strong practicability.It can be divide into three categories,based on that degree of abstraction of the"empirical tower" theory,which can be divided’ into three categories:"abstract experience-observation experience-observation experience",layer-based on the practical teaching situation,the practical learning problem,the teaching difficulty demand,and the education of different learning types,which has the advantages of being an efficient and flexible teaching mode,and the exploration of the feasible teaching plan.The main work contents of the study include the design and development of software,teaching application design,the construction of AR teaching model and the investigation and analysis of teaching effects.The method of classroom behavior evaluation,questionnaire survey and interview is used to analyze the applied research of augmented reality teaching software.The conclusion is drawn that the augmented reality teaching software can simulate the physical model with high fidelity,create a relaxed and free learning environment,and effectively stimulate learners’ interest in learning.At present,the research on augmented reality teaching in China is still in the preliminary exploration stage.It can be predicted that the development of augmented reality technology will inevitably lead to a new round of changes in teaching methods and teaching modes.Its development needs to depend on the improvement of teachers’professional competence,the orientation of information literacy and education reform driven by education technology. |
