Practice Research On Augmented Reality Technology In Training Courses Of Secondary Vocational Schools

Practical courses of electronic information major in secondary vocational schools are an important part of learning electronic technology,and also the key to promoting secondary vocational students to connect theoretical knowledge with practical operation.The application of traditional teaching methods in secondary vocational schools is dull and difficult to understand,the theoretical knowledge is abstract,the teaching efficiency is low,and it cannot effectively stimulate students' interest in learning.It has become a trend to use new information technology to improve the traditional teaching methods in practical courses.As an emerging information technology,augmented reality(AR)technology is widely used in teaching with its features of immersion and real-time interaction.In particular,the fact that the augmented reality system can truly simulate the 3d model of real objects stimulates the spirit of students' independent exploration and makes their learning easy and efficient.Through reading a large number of literature,this paper summarizes the application status of augmented reality technology in education.Aiming at the problems existing in the current teaching mode of practical courses in secondary vocational schools,and the research methods of literature research,action research,educational experiment,and data collection are adopted to conduct the research.The main contents include the teaching feasibility analysis of AR technology,teaching case design,teaching mode design,and the case practice was carried out with two first-year students of electronic information major in Tianjin electronic technician college as experimental subjects.(1)for the experimental class,augmented reality technology is used for course teaching;(2)for the comparison class,traditional teaching method is used for teaching.Through the questionnaire survey,the exercise test paper,observation of experience" as a teaching classroom behavior evaluation index,the results show that the augmented reality technology can be applied in practical teaching of secondary vocational school,can improve students' academic performance to some extent,help students better understand the course knowledge,at the same time compared with the traditional teaching methods,teaching activities based on augmented reality can maintain the classroom students attention,obviously improve the students learning effect,learning initiative is stronger.Finally,this paper summarizes the whole research process and analyzes the shortcomings of the subject research,so as to provide reference for the introduction of augmented reality technology into the practical course teaching of secondary vocational schools.
