Exploration And Practice Of Teaching Methods In Secondary Vocational Education Based On Mapping Knowledge Domain

Secondary vocational education is an important component of modern vocational education and it plays a fundamental role in the development of vocational education.The selection,formulation and adjustment of its teaching methods affect the quality and direction of teaching activities in secondary vocational education.It is necessary and significant to use the visualized tools of bibliometrics to analyze the secondary vocational teaching in a scientific and systematic way and to display the research status and possible development trend in this field concisely and intuitively,which provide the theoretical basis for the in-depth study of teaching methods and for the scientific arrangement of teaching activities in secondary vocational schools.Taking the papers in CNKI database as the research object,we use CiteSpace to make quantitative statistics on the relevant documents in the past ten years.With the visualizations on Mapping Knowledge Domain including institutional cooperation,author cooperation,keyword co-occurrence,keyword clustering and time zone,the frontiers and research focuses on secondary vocational teaching are achieved,the development veins of secondary vocational teaching is explored.Also,the distribution of research topics is obtained.Thus,the theoretical system of secondary vocational teaching is preliminarily constructed.Finally,the teaching model is designed according to the analysis results of Mapping Knowledge Domain and applied to the practice of computer teaching in secondary vocational schools.The main contributions of this paper are summarized as follows:1.Knowledge mapping analysis on cooperative research of teaching methods in secondary vocational education.The analysis results show that most of the research results are achieved by institutions and scholars independently,and the cooperative research needs to be strengthened.Moreover,the related research institutions are mostly from secondary vocational schools,which reveal their not taking full advantage of theoretical achievements in professional universities,so it is quite difficult to produce higher-quality research results.2.Knowledge mapping analysis on the teaching hotspots in secondary vocational education.The results show that the research focuses on the problems and corresponding strategies in teaching reform and innovation,including teaching effect and quality.At the same time,the hot teaching methods include project-based teaching,case-based teaching,task-driven teaching and so on,which are mostly applied in the secondary vocational teaching of mechanical drawing,moral education,computer,and so on.Moreover,the theme distribution in secondary vocational teaching is roughly divided into 11 categories,such as class teaching,teaching design and flipped classroom.And the research frontier includes "preschool education","mechanical basics","electronics","accounting teaching","informationized teaching" and "micro-lecture".3.Knowledge mapping analysis on research topic evolution in secondary vocational teaching.Firstly,the research direction changes from the whole to the part,from the study of teaching reform and innovation to specific teaching methods.In recent years,more attention has been paid to the application research of specific specialties and curriculums.Secondly,looking at the evolutionary research in secondary vocational education,the teaching mode tends to individualized teaching.Moreover,classroom teaching attracts more attention in teacher-student interaction and improves practical abilities.Finally,the use of modern information technology to teaching has also become an increasingly concerned research topic.Generally speaking,preschool education and task-driven method in secondary vocational education are research focuses in 2019,which may be one of the important research trends in the future.4.Blending Learning of task-driven and micro-lecture teaching is practiced and evaluated in secondary vocational teaching.Based on the analysis results of the Knowledge Mapping analysis on teaching methods in secondary vocational education,we designed Blending Learning for information technology curriculum in secondary vocational teaching which combines task-driven teaching and micro-lecture methods.Furthermore,we applied Blending Learning for students of computer major in a secondary vocational school.After a semester of teaching,the teaching effect is evaluated with questionnaire survey.The evaluation results show that the students adapt to Blending Learning quickly and most students like Blending Learning gradually.As a result,the practice ability of students is promoted greatly,and the teaching effect is improved significantly.Therefore,the teaching practice confirms the credibility of the analysis results including research hotspots and frontier on secondary vocational teaching.Moreover,the research results based on Mapping Knowledge Domain would provide some guidance for the current teaching reform and innovative in secondary vocational education,which is of important theoretical significance and practical value.
