Research On The Teaching Design Of The Course "Assembly And Debugging Of Electronic Products" For Mechanical And Electrical Majors In Secondary Vocational Schools Based On STEM Concept

Stem education focuses on the integration of science,technology,engineering and mathematics.The purpose of stem education is to break the boundaries of disciplines,integrate the knowledge of various disciplines,and improve students’ innovation ability and practical ability.At present,China’s economy is facing transformation and upgrading,and the demand for high skilled talents from all walks of life is increasing significantly.However,the current teaching quality of secondary vocational schools in China is not high,and the teaching reform is difficult,which leads to the mismatch between the trained talents and the industry demand.At present,the application of stem education in primary and secondary schools has achieved remarkable results.How to combine stem education with professional courses in secondary vocational schools,what kind of teaching design to guide students’ practice,and how to verify the scientificity and effectiveness of stem teaching in secondary vocational schools have become the key contents of the current secondary vocational reform.Through the methods of comparative research,investigation research and action research,this study first combs the development of stem education and instructional design at home and abroad,and summarizes the current situation and dilemma of the integration of secondary vocational education and stem education in China.Secondly,it analyzes the course of electronic product assembly and debugging of mechanical and electrical specialty in secondary vocational schools.Before the teaching design,it analyzes the curriculum standard and teaching object of this course,and selects the teaching mode.Combined with the relevant ideas of stem education,taking the cultivation of students’ stem literacy as the teaching goal,in line with the general teaching rules,the teaching goal design,teaching method design,teaching strategy design,teaching environment design and teaching evaluation design are carried out,and a complete composition diagram of teaching design is drawn.Thirdly,according to the constructed teaching design,taking a class of mechanical and electrical specialty in Z School of Changzhou City,Jiangsu Province as the teaching object,two cases of "electronic lucky turntable" and "equipment electronic organ" in the course of electronic product assembly and debugging are selected for stem teaching.Before the implementation of teaching,the pre-test is carried out through the scale,and after two rounds of teaching,the post-test is carried out to test the effect of stem teaching design for electronic product assembly and debugging.The results of questionnaire data analysis show that after the stem teaching practice of electronic product assembly and debugging,the students’ interest in the course is significantly increased,the students’ engineering creativity is significantly improved,and the students’ overall learning effect is significantly improved.Through the stem teaching of electronic product assembly and debugging,it can better stimulate the secondary vocational students’ interest in learning electronic product assembly and debugging course,improve the secondary vocational students’ team learning ability,improve the secondary vocational students’ ability to integrate various subject knowledge and solve problems,and improve the students’ stem literacy.
