Research On Project-based Design And Practice Of Mechanical Drawing In Secondary Vocational School

With the continuous development of China’s economy and the acceleration of industrial structure upgrading,emerging fields such as 3D printing and intelligent manufacturing have emerged.At the same time,the era has put forward new requirements for the abilities and qualities of skilled talents.Vocational education plays an important role in cultivating skilled and technical talents,and its scale is almost half of that of education.The quality of talent cultivation directly affects the quality and even structural changes of skilled and technical talents.The "Three Education Reform" task proposed by the "20 Articles of Vocational Education" aims to improve the quality of talent cultivation in vocational education and promote the high-quality development of vocational education.At present,there are problems with strong subject color and weak technical practicality in the basic courses of mechanical majors in vocational schools,and there is an urgent need for textbook and teaching method reform.Among them,"Mechanical Drawing" is a compulsory basic course for students majoring in mechanical engineering in secondary vocational schools,which plays a fundamental role in cultivating professional knowledge and skills.However,the current curriculum structure is severely modularized and segmented,with the content mainly based on the subject system,making it difficult to cultivate students’ comprehensive vocational abilities.Therefore,the current content of "Mechanical Drawing" in secondary vocational schools is optimized and project-based reconstruction is carried out to achieve effective coupling of talent cultivation between schools and enterprises,Is an urgent and extremely important issue.Project courses,due to their unique theoretical advantages and practical achievements,are the mainstream mode and focus direction for vocational colleges to cultivate students’ comprehensive job abilities.Therefore,this article aims to explore a path beyond the development of professional basic courses by conducting project-based development and practical research on "Mechanical Drawing" in vocational schools,with the goal of comprehensive job abilities and guided by project curriculum theory.Firstly,by conducting research,it is necessary to clarify the ability requirements of employees in the company and the existing problems in the current curriculum implementation,and conduct attribution analysis.Secondly,by reviewing a large amount of literature,the logical points and development process of project-based courses are sorted out,and the alignment between the inherent logic of project courses and the demands of mechanical drawing course reform is deeply elaborated,laying the foundation for the subsequent reconstruction of course content.Once again,the ability indicators obtained from the research will be used as input elements to determine course objectives,select course content,organize course structure,optimize teaching methods,reconstruct course evaluation,and carry out project-based development of Mechanical Drawing.Finally,the restructured course project will be put into teaching practice in order to revise and verify the results of project-based development of the vocational school’s "Mechanical Drawing" course.The research mainly achieved three results.Firstly,it investigated the gap between the current achievement of talent cultivation and the ability of mechanical positions.Secondly,the content of the mechanical drawing course in vocational schools should be reconstructed based on job abilities and projects.Finally,the feasibility and effectiveness of project-based development of mechanical drawing courses were verified through teaching practice,effectively breaking through the problems existing in the current mechanical drawing courses in vocational schools,and providing ideas for the reform of basic courses in other majors.
