Study On Design And Practice Of Mechanical Drawing Course In Secondary Vocational School Based On OBE Under Modern Apprenticeship System

Under the background of the continuous development of education reform,the country has made continuous exploration in education and teaching mode in order to promote the high-quality development of vocational education personnel training.On May 1,2022,the revised Vocational Education Law of the People’s Republic of China came into effect,elevating the modern apprenticeship system to a national level and establishing it in legal form.However,through the investigation of apprenticeship pilot enterprises,it is found that there is still a certain gap between the professional ability and comprehensive quality of students in secondary vocational schools and the talent demand proposed by some apprenticeship pilot programs.In order to narrow these gaps and improve the quality of talent training,school curriculum teaching plays the most direct and critical role.Therefore,this study will closely focus on the curriculum of secondary vocational schools to carry out in-depth exploration based on the concept of OBE education,so as to solve the current problems and help the implementation of modern apprenticeship.Based on this,this study focuses on the application major of numerical control technology in secondary vocational school,takes Mechanical Drawing as an example,and through the methods of literature research,investigation and experimental research,summarizes the deficiencies existing in the classroom teaching of Mechanical Drawing in secondary vocational school in terms of teaching content,students’ professional quality and teaching evaluation system,and analyzes them,and proposes solutions to the problems faced.Construct the teaching process of Mechanical Drawing based on OBE in secondary vocational schools.This teaching process attaches importance to the connection with actual jobs.It uses the reverse design concept of OBE to carry out enterprise research and vocational post ability analysis in the early stage of teaching,and then formulates the final learning outcomes of students.It also reconstructs learning content around typical work tasks to form learning situations and tasks,and designs multi-mode,multi-content and multi-subject teaching evaluation methods.To establish a case material database of artisan spirit to help students develop professional quality.Using the teaching process design case of Mechanical Drawing based on OBE in secondary vocational schools,this paper selects Class 1 of 2022 numerical control Technology Application in a vocational and technical school in Changchun for teaching practice,and compares the teaching effect of this class with other traditional teaching classes.By comparing the learning results of the experimental class and the traditional class and summarizing the teaching effect questionnaire,it is proved that the improvement measures of the mechanical drawing course in the secondary vocational school are feasible and the teaching effect is good,which can accelerate the mutual penetration of the school and the job,promote the improvement of students’ professional knowledge,professional skills and professional quality,and thus improve the teaching quality.It is of practical significance to build a good teaching ecology of secondary vocational education.
