Abstract: “Engineering Ethics” is a core course of engineering professional degree graduate with strong practicality, which plays an important role in cultivating students’ engineering ethical consciousness, normative cognition and ethical decision-making ability. Aiming at the problems existing in online teaching of “Engineering Ethics”, based on the concept of OBE, teaching team has built a website of “Engineering Ethics” course and constructed scientific online teaching content. With students as the center, the online teaching links of “online self-learning + live teaching + online interaction + online homework + online question answering” have been implemented by innovativing online teaching method, which could mobilize students’ enthusiasm for learning and ensure the participation of online teaching. The course takes engineering ethics cases as the main line, curriculum ideology and politics as the soul, and case teaching as the feature to stimulate students’ interest in learning and improve the quality of curriculum education. The course is ability-oriented and pays attention to the learning process assessment, which forms a diversified assessment method. The “Engineering Ethics” teaching system integrating OBE concept and curriculum ideological and political education is constructed to achieve the homogeneity and equivalent of online and offline teaching. These measures provide experiences and references for further effective online teaching.
