Outcomes-Oriented Teaching Design And Practical Research Of Secondary Vocational "Mechanical Drawing" Course

With the rapid development of China’s intelligent manufacturing and the continuous upgrading of the industry,higher requirements have been put forward for the quality of skilled talents,and secondary vocational education as an important part of vocational education,the improvement of its teaching quality is of great significance to achieve the cultivation of high-quality skilled talents.As a professional course combining theory and practice,"Mechanical Drawing" not only focuses on the cultivation of students’ ability to read drawings and drawings,but also attaches importance to the enlightenment of students’ spatial imagination and logical thinking ability.However,at present,the course of "Mechanical Drawing" still has problems such as outdated teaching content,lack of goal guidance,unclear positioning of teaching goals,lack of development,lecture-based teaching methods,lack of interaction and thinking,and single evaluation methods.Because of this,the outcomes-oriented concept can reconstruct classroom teaching and provide new ideas for this course,this study runs the outcomes-oriented concept through talent training,constructs a teaching design based on the outcomes-oriented education concept,and carries out teaching practice in the middle vocational "Mechanical Drawing" course to verify the effectiveness of the proposed teaching design.Through literature research,this study sorts out and analyzes the research status of outcomes-oriented education concept and "Mechanical Drawing",takes students majoring in mechanical and electrical technology application and teachers of front-line drawing course teaching as the survey objects,investigates the current teaching status of secondary vocational "Mechanical Drawing" course,analyzes and summarizes the survey results,and discusses the feasibility of applying the teaching design based on the outcomes-oriented education concept to the teaching of "Mechanical Drawing".With the support of competency-based education theory,mastery learning theory,Bloom classification learning theory and constructivist learning theory,and referring to Richard’s instructional design model based on effectiveness education theory,the instructional design based on outcome-oriented education concept is finally designed.The design includes three major links: expected learning outcome design,teaching activity design(to achieve learning outcome design)and learning outcome assessment design,and each part is elaborated in detail.Taking the "Mechanical Drawing" course as an example to carry out teaching,comprehensively considering the needs of enterprises for talents,learning conditions,talent training programs and curriculum standards,etc.,formulate the overall teaching objectives of the course,refine and divide the teaching objectives,specifically the ability index points,and determine the expected learning results.Then,the teaching content is reconstructed according to the expected learning outcomes,and six typical items are sorted out,which correspond to the ability indicators available in the projects.In the effect analysis,the achievement of competency index points,project quality and related achievements of the research subjects were analyzed in the data analysis,and the students participating in the experiment were interviewed to explore the effectiveness of teaching design based on the concept of outcome-oriented education.The final practical results show that the teaching design of secondary vocational mechanical drawing based on the concept of outcomes-oriented education,guided by learning outcomes,reconstructs teaching content according to expected learning outcomes,uses rich teaching methods,and optimizes evaluation methods,which can promote students’ learning effect and improve comprehensive practical ability.
