Study On Discovery Teaching Method For The Course Of "Computer Assembly And Maintenance" In Secondary Vocational School

At present,with the rapid development of computer,the teaching methods and means of computer related majors in secondary vocational schools have not been significantly improved.In particular,the course of computer assembly and maintenance is faced with problems such as insufficient number of computer hardware equipment,slow update speed and single teaching method,which leads to low learning enthusiasm and unsatisfactory teaching effect for students.Therefore,in order to cultivate high-quality and skilled talents in secondary vocational schools,the teaching reform of the course computer assembly and maintenance is imminent.Firstly,the project-based discovery teaching method is adopted in this paper,and virtual reality technology is also applied to build a computer assembly and maintenance learning environment at the same time,so that students can effectively master the whole process of computer assembly and maintenance,as well as stimulate the students’ enthusiasm for learning,while provide timely feedback on the learning effect through learning data.The research background and significance of the topic are clarified,and the research status of the project teaching method and discovery teaching method at home and abroad are introduced through extensive literature reading,and the advantages and disadvantages of each method are summarized to lay the theoretical foundation for the subsequent chapters.Secondly,the detailed design of the project-based exploration and discovery teaching method in the course computer assembly and maintenance consists of virtual teaching resources,teaching process,and diversified evaluation methods.According to the practical computer training process,a set of perfect virtual teaching environments is designed,which includes three basic simulation libraries namely computer parts library,configuration and assembly training library,computer failure scenario library,and a pass promotion platform.The teaching process is designed with a project as the mainline.According to the student’s knowledge base,learning habits,and teaching status as grasped by the questionnaire survey,students are divided into several groups to achieve knowledge construction by completing different projects in the virtual teaching environment.As the main unit of teaching activities,students discover the problems to be solved in a specific project by themselves and divide the work among the groups.The teacher gives appropriate guidance to them as they explore their problems in the resource library.Group members work together to complete the project and share their problem-solving process,and the teacher makes a summary based on the students’ completion.A diversified evaluation method is designed to reflect the learning effect,specifically in terms of diversified subjects and diversified methods.Finally,the project-based exploration and discovery teaching method was practically applied in the teaching of the course computer assembly and maintenance,and the teaching effects were analyzed.Firstly,the practice objects were set up,including the experimental class and the control class,and the teaching practice was carried out for 67 students in the experimental class in terms of preview and classroom learning,and the teaching effects of the experimental class and the control class were compared and analyzed in terms of learning performance,learning interest and learning style to verify the effectiveness of the method proposed in this paper.The actual teaching process and results on the teaching effect show that the method proposed in this paper can largely promote students’ interest in learning computers,improve teaching conditions and enhance students’ practical computer operation capabilities.It provides an effective means for the teaching reform of the course computer assembly and maintenance and guarantees the cultivation of high-quality skilled talents in the secondary vocational schools.
