Students and faculty at Middle Tennessee State University (MTSU) are exploring new ways of teaching and learning in master classrooms. Master classrooms are specially equipped classrooms that contain a wide range of computer, media, projection, communication, and control capabilities, including connection to the campus network. Master classrooms typically contain one computer, which can be used by instructors and students for presentation development, simulations, on-line access, and multimedia. This paper contains information on the development and implementation of master classrooms. Topics include: planning for rooms; renovating and developing rooms; purchasing equipment; utilizing the rooms; campus network and Internet connections; training and supporting faculty; maintaining and upgrading equipment and software; conducting evaluations and implementing suggestions; problems with scheduling, maintenance, staffing, and too few master classrooms; and planning for the future, including "portable" master classrooms and new master classroom construction at MTSU.
