Reform and Practice of Online-Offline Blend Teaching of Engineering Ethics Incorporating Political Elements

This paper describes the reform and practice of changing the engineering ethics course from offline to blended online and offline teaching. The course integrates theoretical teaching and case practice and is conducted in the form of video lectures and group discussions. The online part focuses on the study of basic theories, while the offline part focuses on case studies to cultivate students' ethical awareness and moral reasoning ability. The course fully integrates political elements and emphasizes the cultivation of students' sense of social responsibility and correct values. Practical teaching is organized in the form of science lectures, debates, and drama performances, and a variety of case studies are conducted. The teaching process adopts the method of "one main line, two parallel tracks" and forms a closed-loop teaching process. The politics of the course are integrated into all aspects of resources, classrooms, and practices. The reforms have yielded good results in teaching and learning, and students' sense of active learning and practical skills have been enhanced.
