For the past four years, Indiana University-Bloomington has used an ecosystems approach to environmental assessment to evaluate the programs, services, and personnel of its residence halls. In October 1981, undergraduates (N=710) living in residence halls completed a questionnaire about the residence hall environment. The questionnaire included an environmental referrent section which gave students an opportunity to identify questionnaire items they felt strongly about, indicate why they felt strongly, and recommend actions to enhance the issues addressed by the items. A comparison of 1981 results with results from the previous three years revealed that residence hall personnel continued to receive high marks for their efforts. Student government received reasonably positive marks, while programs offered in the centers received a wide range of responses from students. Recreational programming appeared most successful, followed by social programming and academically-oriented programming. Students reported a negative response toward the availability of personal development programs and guest speakers. Responses to three items addressing the academic environment in residential centers, when compared to results from previous years, indicated that study conditions were improving. An item addressing personal security also improved considerably in 1981. The results suggest a reasonably high quality experience for students. (NRB)
