The combination of project-based and discussion teaching has been proposed and experimented with in practice in this paper, concerning the characteristics of atmospheric remote sensing technology in course. In practice, the students were encouraged to involve in study and research by the introduction of classified discussion into class, based on the idea “learn from better; absorption and summary; and then adaptation; practice” with respect to the teaching content. The specific part of the teaching reform has been depicted, and then the desirable results have been illustrated, which provided value for the expansion to the other courses.
