Abstract: Ideological and political construction of college curriculum is a strategic measure to implement the fundamental task of moral education. Relying on the remote sensing elective course Looking at the Earth from Afar, Exploring the Changes of Universe and Earth, the ideological and political elements contained in “remote sensing” are fully explored and the abundant popular science forms were utilized to construct the teaching mode of “Ideological and Political Guidance & Science Popularization Drive” for remote sensing public elective courses. Taking advantage of the characteristics of wide range of students and flexible teaching methods in public elective courses, combined with the characteristics of unique remote sensing knowledge and strong application, this course adopted a scientific, novel, open and interactive mode to realize the imparting and cross-exploration of remote sensing technology knowledge, which provides a strong support for the inheritance of popular science. The combination of explicit knowledge education and implicit ideological and political education cultivated students' spirit of serving the majors and the grassroots, which was well received by the students. Students’ knowledge range and thinking of remote sensing have been significantly expanded, giving play to the educational advantages of public elective courses.

Key words: ideological and political, science popularization, remote sensing, public elective courses
