Educational Applications of Collaborative Innovation under Engineering Accreditation: A Case Study of “Digital Signal Processing”

Abstract

This paper takes the case study of “Digital Signal Processing” to explore the educational applications of collaborative innovation under engineering accreditation. Digital signal processing is an emerging discipline that involves multiple disciplines and is widely applied in many fields. This course is the core foundational course of communication engineering, but it is highly theoretical, difficult to understand, and hard to master. To solve these issues, this paper explores teaching reform solutions from collaborative ability, creativity, classroom teaching methods, and educational philosophy to help students firmly grasp the fundamentals of science, mathematics, and engineering, meeting the demand for talent in the future engineering industry. The digital signal processing course group of Liaoning Technical University has carried out reforms and practices in several aspects, such as classroom teaching models, experimental teaching, and performance evaluation mechanisms. After three semesters of practice, the qualitative achievement of the course has increased by an average of 14.04%, and the quantitative achievement by 5.55%, indicating that the students’ interest in the course, their ability to apply the knowledge of the course, their ability to practice engineering, and their ability to work in a team have all improved greatly.
