In an effort to put into action an increased interest in interdisciplinary teaching at the higher education level, a model for interdisciplinary instruction was designed and used for a seminar on ancient urbanization and city development. The model for the seminar used what Robin Fogarty has termed "webbed" likening this perspective to that of a telescope, with "a broad view of a constellation as one theme, webbed to the various elements." The format was a seminar with about 12 students and 2 primary objectives: to provide a historical survey of the origins and early development of urban centers and to introduce students to the problems commonly facing urban societies. Student study focused on city planning, politics, the economy, sociology, and leisure. Four texts provided background material. Introductory presentations illustrated the origins of the city in various areas. Then students researched specific cities in a case study format. The webbed approach was particularly helpful in the case study work. After students observed presentations on several cities, they presented their own case studies of the cities they had chosen to research. The seminar also used CD-ROM programs that have been developed to study cities of Ancient Greece. These programs, one of which is interactive, contain a data base of reference materials, libraries of major authors, and various types of graphics. (JB)
