Research On The Teaching Of Secondary Vocational Computer Courses Based On PBL Pedagogy

Nowadays,the development of information technology is getting faster and faster,and with the frequent issuance of national policy documents on vocational education,the status of vocational education in China is gradually improving.In the context of such an era,the society is more and more in need of professional and skilled talents,and secondary vocational schools have ushered in an important period of rapid development.In recent years,due to the trend of changing the secondary vocational curriculum to the direction of application and professionalization,the teaching mode of secondary vocational classroom is bound to continue to explore from the traditional teaching method to all directions.In this paper,based on the educational concept and training objectives of secondary vocational schools,the PBL pedagogy is selected to be applied to the secondary vocational computer major,and the feasibility of PBL pedagogy in this field is explored.The PBL teaching method is a teaching method that takes the problem as the starting point and cultivates students’ ability to cooperate in learning and analyzing and solving problems,but in its specific implementation,there are shortcomings such as poor initiative of some students and difficulty in cooperation within the group.In order to promote the reform of the teaching mode of secondary vocational computer majors and promote the practice of students’ professional skills,this paper combines the actual situation of secondary vocational schools,designs the implementation steps of PBL teaching method,and takes the "C Language Programming" course as an example to conduct PBL teaching method experiments in a secondary vocational school in Hunan,analyze its teaching practice effect,and provide certain ideas for the reform of PBL teaching method in secondary vocational school computer professional courses.Starting from the problems existing in the classroom teaching of secondary computer majors(taking "C Language Programming as an Example"),the following specific studies are carried out:(1)Through the literature research method,the relevant research on PBL was sorted out,and the basic research situation of PBL teaching method was understood from the aspects of domestic and foreign research status and related theoretical basis.(2)Questionnaire and interview survey analysis of the teaching status of secondary vocational computer professional courses,investigated the classroom teaching status of the "C Language Programming" course,sorted out the relevant data and content of the questionnaire and teacher interviews,analyzed and summarized the shortcomings in the teaching of the current "C Language Programming" course in secondary vocational schools,and designed the teaching process of the PBL teaching method based on these deficiencies: pre-class resource learning,creating problem situations,group exploration,eliciting new knowledge,and raising task questions again.The group worked further to explore problem-solving ideas,followed by a presentation of results and evaluation reflection.(3)The textbook of "C Language Programming" is interpreted,the objectives and content of the specific chapters of the textbook are further analyzed,and the introduction problem set of each chapter and the teaching design of the PBL problem-oriented teaching method are designed,which are applied to the teaching of the "C Language Programming" course of the secondary computer major,and the feasibility of the PBL teaching method applied to the teaching of the implementation course is tested.(4)Through the sorting out of the post-questionnaire,student interviews and final grade data,the teaching effect of the PBL teaching method applied to the "C Language Programming" classroom is analyzed,and the analysis results show that PBL can improve the ability of students to analyze problems and solve problems,which is conducive to students’ independent learning.Finally,this experiment is summarized and its shortcomings and prospects are analyzed.
