The Application Research Of Blended Learning Mode Based On OBE Concept Of 3D Printing Training Course

With the continuous development of advanced manufacturing technology and the deepening of curriculum reform in secondary vocational colleges,the application prospect of 3D printing technology has aroused widespread concern of educators in secondary vocational colleges.My school will build 3D printing technology into a new advanced manufacturing technology training course for numerical control processing(intermediate skills).The original purpose of the course is to let the students of numerical control processing major more contact with advanced manufacturing technology,cultivate their innovation ability and practical ability,stimulate their interest in learning,and promote the establishment and promotion of their professional quality and sense of responsibility.Secondary vocational education is the starting point of vocational education.The improvement of the development level of secondary vocational education is essentially to improve the quality of personnel training,and the key to improve the quality of personnel training depends on curriculum and teaching,so curriculum construction and teaching reform is imperative.Educational information promotes the change of learning style,and hybrid learning mode emerges as the times require,which is widely praised for its ability to stimulate learners' initiative and creativity.Under the influence of the "one belt and one way" policy,vocational education should be internationalized.Under the advocacy of "Dublin agreement" in secondary vocational education,the curriculum construction and teaching reform of secondary vocational education should adhere to the student oriented and result oriented OBE teaching philosophy.In this context,this research is based on exploring the teaching practice of 3D printing technology in secondary vocational schools,an advanced manufacturing technology training course-"3D printing training",which is based on numerical control processing specialty,integrates the OBE concept into the teaching design of hybrid learning mode,and carries out the OBE concept based hybrid learning design through the task of "colorful luban lock processing" The specific design and display of integrated learning mode.The author takes the teaching practice of two classes in the first grade of numerical control processing major in our school as the object,according to the learning characteristics of secondary vocational school students,implements the teaching task of "processing colorful Lu ban lock",and conducts teaching practice and investigation analysis on the students in the teaching class,and draws the conclusion that the mixed learning mode is adopted in the 3D printing training course of secondary vocational education It is feasible in the process,providing reference and reference for teachers who study 3D printing training course in the future.Finally,the author puts forward the shortcomings of the study and research prospects.
