The purpose of this study was to determine and illuminate the relationship between setting and use at the Workshop Center for Open Education (City College of New York) as observed by participants, staff, and investigators. Data were collected during the academic year 1979-1980 by questionnaire, interview, and observation. The use of the Center since its inception in 1972 continued to evolve in reciprocity with its setting. In a typical day, staff at the Center gave tours, provided resource information, conducted classes and workshops, showed films, and arranged for new activities, in addition to answering correspondence and telephone queries. The Center was used by a variety of groups for overlapping reasons: teachers, students, City College faculty, Center staff, and by parents, principals, and administrators. Since the range of facilities at the Center defied singular use, a complex pattern of actions and reactions was found among users. The dense setting made browsing, observation, and interaction the prime uses of the Center. Participants experienced themselves as whole, active people engaged within a setting they perceived as authentic, and interpenetrating of people, action, and reflections. Appendices include study methods and procedures, the questionnaire and responses, and summaries of funding sources, use statistics, and staffing. (FG)
