Abstract: Electronic information engineering students should have a profound engineering accomplishment.The implementation of inquiry-style small class teaching and challenging courses,further promote the cultivation of professional students' engineering accomplishment.This article discusses how to combine the “basic courses of circuit and electronic circuit and other professional basic courses,specifically to promote the engineering accomplishment training.These courses have both rich theory and a large number of engineering practice problems.By combing the contents of the course,the combination of classroom teaching and extracurricular learning,especially the extracurricular learning requirements which includes the academic frontier,the literature reading comprehension and studying circuit law by experimental methods,training students to solve scientific problems in scientific methods,and ultimately enhance the students' engineering accomplishment.
