Research On The Application Of Micro-course In The Teaching Of Electrical And Electronic Courses In Secondary Vocational Schools

Today,with the rapid development of information technology,modern educational technology has also been greatly developed.The popularization of information technology has brought great convenience to modern education and teaching.Micro-course is a new teaching method of information technology.How to apply micro-course to the teaching of Electrotechnics and electronics? This is the subject of this paper.Based on the constructivism theory,information technology theory,instructional design theory and situational learning theory,this paper explores the application design of micro-course in the teaching of electrical and electronic courses in secondary vocational schools by using micro-course as an assistant means of teaching,and takes "current limitation and partial pressure" as an example to analyze the teaching process and application of micro-course.Finally,the teaching effect of micro-course in Electrotechnics and electronics is analyzed and some teaching suggestions are put forward.Combining modern technology with curriculum,promoting teaching reform and improving teaching quality are the important contents of this research.Firstly,through the analysis of the teaching and students' learning of electrician and Electronics Curriculum in secondary vocational schools.Teachers are lack of subjectivity,backward teaching methods,poor students' ability and unreasonable assessment;students are weak in foundation,lack of interest in learning,unclear learning objectives,unscientific learning methods and poor self-control ability.In view of this situation,the application of micro-course in the teaching of Electrotechnics and electronics is proposed.Secondly,taking "current limitation and partial pressure" as an example,the design of teaching application is carried out from three aspects: topic selection,teaching design and recording of micro-courses,in order to improve teaching quality and students' learning atmosphere.Finally,the designed micro-lesson is applied to the actual teaching.In this study,40 students in two electrician and electronic courses were selected as the research objects.The specific implementation process includes: determining teaching content,arranging teaching tasks,displaying and watching micro-courses,displaying and completing homework,teachers' questioning,after-class summary and reflection,and teaching evaluation.The results show that micro-class teaching can not only improve students' interest,enthusiasm and attention in learning,but also improve the quality of teaching.It can also focus on solving some difficult problems,making students easier to understand and achieving good teaching results.This study has certain reference value and reference significance for the teaching of theoretical courses in secondary vocational colleges.
