The coming of the information age opens up rich resources and approaches for education, and at the same time brings opportunities and challenges to teaching and learning. Based on Outcome Based Education (OBE) teaching philosophy, aiming at the teaching spot problems existing in the principles of chemical engineering, this paper constructs a "five-in-one" teaching mode, including case analysis, theoretical teaching, project-driven teaching, ideological and political guidance as well as network assistance by using of the internet and combining the development needs of life and national low-carbon environmental protection, which starts from the requirements of continuous improvement under the background of engineering certification. Moreover, the innovation teaching mode fully reflects the mutual integration of knowledge objectives, ability objectives and quality objectives, and meets the needs of applied personnel training under the background of emerging engineering education.
