This study reports on a collaborative teaching project involving a news reporter and two primary school teachers. The teaching group jointly designed and implemented a fourth grade primary school media literacy course for a class of 27 students based on their respective domains of expertise, so as to explore the feasibility and efficiency of collaborative teaching. The study adopted an action research approach, and found that the students’ understanding of media literacy had improved significantly by the end of the course. The study also found that both cooperating teachers and students felt that the content and instructional design of the course were innovative and practical.
