Abstract—Based on the goal of “combining knowledge teaching with value orientation” in curriculums in colleges and universities, and combined with the characteristics of science and engineering, the system design of ideological and political education in science and engineering teaching is established and carried out. The system design and implementation scheme realize the value orientation, unifies the curriculum ideological and political idea with the science and engineering related courses. In this context, new teaching mode has been established, which integrates knowledge teaching, ability training and education. Moreover, a series of combination points and penetration points of science and engineering class teaching have been explored and designed, to integrate and refine the educational resources in science and engineering courses, as well as a variety of appropriate teaching methods be designed. The evaluation mechanism of curriculum ideological and political education is constructed to realize the organic unity between ideological education and science and engineering teaching. Combining the value orientation, ability training and knowledge imparting organically, and going against the formation of ideological and political courses, the fundamental task of "cultivating morality and cultivating people" in science and engineering education can be fulfilled to guarantee the quality of personnel training.
