Abstract: Based on the characteristics of electrical majors,it analyzes the existing problems in engineering maintenance practice teaching.In order to enhance students ability to solve engineering problems through self-study during the internship process,the paper proposes a combination of Internet and practical teaching to improve teaching ideas.The method of applying information technology to engineering maintenance teaching and achieving deep integration is studied.The practical results show that this teaching method improves the students’ engineering ability and learning enthusiasm,strengthens the combination of theory and practice,solves the problems of technical gaps between practice and practical work,improves the teaching quality of internships,and achieves good teaching results.In engineering practice teaching,the application of Internet+PBL teaching method is very worthy of promotion.
