Research On The Application Of Virtual Simulation Technology Under The Concept Of "Integration Of Theory And Practice" In The Course Of Mechanical Foundation In Secondary Vocational Schools

In recent years,the state has issued a series of educational reform policies to improve the level of secondary vocational education,and has repeatedly proposed to break the traditional single vocational education teaching model and realize the integrated development of education and modern technology.The course "Mechanical Basis" in secondary vocational schools is a professional core basic course for mechanical related majors,and it is one of the courses that mechanical and electrical students must master.In this paper,the teaching concept of "integration of theory and practice" is integrated with virtual simulation technology,and it is applied to the teaching of "Mechanical Basis" in order to improve the serious separation between theoretical teaching and practical teaching in traditional teaching and promote students to "learning by doing" and " doing by learning".Firstly,on the basis of summarizing and analyzing the relevant research literature at home and abroad,the research plan and principles of this paper are formulated on the basis of constructivism theory,situational cognition theory and Tao Xingzhi’s thought of teaching,learning and doing in one.Secondly,through questionnaires and interviews,we understand the current teaching and learning situation of Mechanical Basis course in secondary vocational schools,and find that there are some problems in the current teaching of Mechanical Basis course,such as less practical teaching hours,rigid teaching mode,single teaching method and lack of diversified information teaching resources.According to the results of investigation and analysis,some contents of the course are selected to carry out the course teaching design based on the concept of "integration of theory and practice",and the course teaching cases are developed and applied to the course teaching by using tools such as Unity3 D engine.Finally,the teaching content of "Cognition and Disassembly Experiment of Retarder Structure" is selected to carry out specific teaching practice research on students,and the learning effect of virtual simulation teaching based on the teaching concept of "integration of theory and practice" is evaluated by counting students’ performance and academic achievements in teaching practice.Practice has proved that,compared with traditional teaching,students’ virtual simulation teaching under the guidance of the teaching concept of "integration of theory and practice" is more active,and they also prefer the teaching form of integrating virtual simulation technology,which shows that the application of virtual simulation technology under the guidance of the concept of "integration of theory and practice" can effectively stimulate students’ learning interest and better cultivate students’ autonomous learning ability and hands-on operation ability.
