Abstract: The main concept of engineering education professional certification is a result-oriented education mode centered on all students. In order to improve the teaching effect and cultivate students’ practical and innovative ability. This paper takes the course of “Digital Signal Processing” from the School of information engineering of Nanchang Hangkong University as an example, and proposes measures to clarify the objectives of the course, revise the syllabus,integrate teaching content, enhance teaching methods, consummate the assessment, and strengthen continuous improvement. Through the implementation of the teaching reform for 2017 grade automation undergraduates, it is found that the teaching reform has fully mobilized the students' learning initiative and enthusiasm, and improved their ability to solve practical engineering problems
