Berge's Instructor's Roles Model categorized the instructor's roles as pedagogical, social, managerial, and technical. Developed more than a decade ago, this model described changing roles for instructors as they transitioned from in-person classrooms to teaching online. Today, as virtual worlds emerge and are being used as educational platforms, these same roles are valid, but again the emphases for teaching in virtual worlds are different than those in online or in-person classrooms.
