This study is using action research design to explore the learning outcomes of applying interdisciplinary cooperative learning as a strategy in teaching geometry as an innovative professional, general and liberal education course in university. The idea of this course design is to blur the boundaries between general and professional courses. It aims to develop professional general and liberal education course taking the history of the development of geometric concepts, basic theories in college geometry and their related applications as  the core. Cooperative learning is facilitated by pairing math and non-math major students to discuss specified geometric topics from each other’s professional perspectives. The analysis of the research data shows that the course plan and the use of cooperative learning had positive impacts on the learning outcomes for both groups of students.
