The Construction And Application Of The Learning Evaluation System Of The "Basics Of Electronic Technology" Course In Secondary Vocational Schools

With the changing times,the society's demand for professional and technical talents is increasing.Especially the development of manufacturing industry has made the gap of talents in electromechanical profession more and more obvious.As the main force in delivering professional and technical talents to the society,the training of professional talents in secondary vocational education has received more and more attention.The study of professional courses is the key for students to master professional knowledge and skills,cultivate professional abilities and professional qualities,and achieve development.The results of scientific learning evaluation can provide motivation,improvement and feedback to curriculum teaching.Therefore,it is meaningful to study the learning evaluation of the electromechanical professional courses in secondary vocational education.This article selects the basic course “Electronic Technology Fundamentals” for the secondary vocational electromechanical specialty as the object for research.First of all,the author clarified the basis for the construction of the evaluation system of the course “Electronic Technology Fundamentals” in secondary vocational schools from four aspects: theory,industry demand,student psychology and curriculum characteristics.Secondly,after investigating the current status of learning evaluation of the “Electronic Technology Fundamentals” course,the author found that there are four outstanding problems: the low sense of presence of the students in the evaluation subject,too much emphasis on limited and measurable behavior,focusing too much on learning outcomes,the evaluation method is mainly quantitative evaluation.This article believes that the reasons for these problems include teachers' concept deviation and insufficient ability,students' immaturity and misunderstanding of evaluation.In order to solve the above-mentioned problems,this research carried out the construction of the learning evaluation system of “Electronic Technology Fundamentals” in secondary vocational schools.This learning evaluation system is mainly composed of four parts: evaluation objective,evaluation subject,evaluation content and evaluation method.The evaluation objectives are different according to the purpose,level and object.The main body of evaluation includes students,teachers and enterprises.The evaluation content includes professional knowledge,professional skills,key abilities and professional qualities.In terms of evaluation method,quantitative and qualitative are combined.In order to evaluate learning accurately and efficiently,the author has designed evaluation tools such as student self-evaluation form,evaluation form of students' performance in class,form of student self-assessment and mutual assessment,form of group member self-evaluation and mutual assessment,summary report(individual/group)and enterprise evaluation form.Finally,select the “series adjustable regulated power supply” in the theoretical part,the “simple test of transistors” and “the test of combinational logic circuit” in the practical part,and conduct an integrated teaching evaluation design to illustrate how to implement the evaluation system.The secondary vocational “electronic technology foundation” course learning evaluation system obtained in this research meets social needs,reflects“student-centered” and pays attention to the whole process of student learning.
