Application Of Task-oriented AR Interacion In The Teaching Of Secondary Vocational Courses

The task-oriented teaching method is a common teaching method in secondary vocational schools.It is guided by specific work tasks and harvests knowledge and skills in the task exploration process.However,in the process of teaching,the concept of teachers is vague,and with the lack of a situational atmosphere,students' enthusiasm will be low and they will not be able to mobilize participation.And AR(Augmented Reality)education transforms abstract concepts into real images,uses animation or 3D models to explain professional vocabulary,strengthens students' conceptual learning and spatial cognition,reduces students' cognitive load,and improves students' interest and concentration.Under the background of new-type technology education,it is not suitable for teachers to select tasks in job-oriented secondary vocational education.Students are unable to start,and there are few stations for auto repair professional training courses.Students lack the practical ability to exercise and adopt theory and experiment.A combined approach to study the task-oriented AR interactive teaching model.This study first analyzes the related literatures of augmented reality education application at home and abroad,and draws the characteristics of augmented reality education and the main points of instructional design.Then,from the work-oriented secondary vocational education research,understand the task-oriented teaching method in secondary vocational education.Then,the application model of job-oriented AR interactive teaching in the teaching of secondary vocational courses is constructed.The interaction diagrams of teachers,students,work tasks and AR resources areconstructed,and the design concepts,teaching objectives,work tasks,learning resources,teaching and teaching evaluation are designed according to their relationship.Secondly,the recognition software based on augmented reality is designed as a teaching aid,and the function module is designed according to the teaching content.Finally,according to the constructed model design experimental scheme,the quasi-experimental research method is used to carry out experimental research in the experimental class and the ordinary class to verify the effectiveness of the task-oriented AR interactive teaching mode.Through experimental research,it is found that the task-oriented AR interactive teaching can enhance the enthusiasm and concentration of students' learning,activate the classroom atmosphere and enhance the teaching effect.The data shows that the average scores of the experimental classes are significantly higher than the average scores of the average class,indicating that the task-oriented AR interactive teaching method can improve students' theoretical learning level and practical ability.
