Application Research Of PBL In Computer Major Courses Of Vocational Education-

The goal of vocational education is to cultivate high-quality professional talents,which is related to the future and development of the country.However,the current teaching effect of vocational education is not satisfactory,especially the computer-based curriculums,which are extremely practical and operational.The traditional teaching-demonstration-on-machine teaching method cannot satisfy students mastering of professional knowledge and professional skills,which has greatly restricted the talent output of the profession."Problem-Based-Learning" takes the problem as the core and takes the actual problem situation as the starting point.Students solve problems by collecting,analyzing and processing information.In this way,students have a good grasp of professional basic knowledge,the ability to transfer and apply knowledge has been improved,and the overall level of learning has been significantly improved.It is a talent training model that is in line with vocational education.This research is mainly to improve students' mastery of professional knowledge and skills through the application of Problem-Based-Learning mode in vocational computer courses.The research contents are as follows:1.Through in-depth study relevant theories and teaching practices of"question-based problem-solving teaching" at home and abroad,the research status of the research has been basically mastered;2.Taking the relevant theories of pedagogy as the starting point,it demonstrates the role of“Problem-Based-Learning”in improving students' learning level and promoting their mastery of professional knowledge and professional skills;3.Based on the PBL model of Barrows and Hmelo-Silver,a PBL model suitable for this study was constructed;4.The PBL model constructed in this study has been proved to improve the learning level of students through the scientific teaching design,application and the classroom teaching practice of the course "Database Principles and Applications".Finally,the results and deficiencies of this research are summarized and reflected.The Problem-Based-Learning has a significant effect on the improvement of students' learning level.Taking the actual problem situation as the starting point,it strengthens the mastery of the basic knowledge in the process of solving the problem,promotes the use of knowledge,the analysis and judgment of the students.The high-level thinking ability such as innovation has been improved,the teamwork ability has been enhanced,and the interest in learning has been greatly improved.
