This paper describes the experiences of the author and other faculty members in a CIS department that encourages sharing of web-based teaching materials. This includes using materials developed by other faculty, and creating materials for others. These experiences indicate that such materials can increase productivity. Another benefit is that the materials make it easier to teach modules on topics in which the instructor has little or no previous experience. However the productivity gains are somewhat offset by the need to keep the materials up-todate, and to adapt them to individual teaching philosophies. One weak link in this process is the lack of procedures for managing the materials and incorporating feedback based on classroom experience, and on discovery of additional relevant content.
