This paper presents the results of a study concerning the impact of changing demographic on curriculum and instruction in higher education and specifically, the impact of the adult student population on Otterbein College, Ohio. The study discusses gender and age considerations in its exploration of the school's student attitudes, teaching practices, goals, and outcomes. The purposes of the study were: (1) to evaluate existing academic services for adult students in terms of their effectiveness, need, and availability as compared with services provided traditional students; (2) to sensitize faculty to existing conditions and encourage careful consideration of instructional alternatives; and (3) to determine the applicability of the project findings to other institutions. The report discusses results obtained from a student survey in the areas of what students perceived to be significant learning experiences, the learning styles of males versus females, what impact adult students had on the instructional setting, and whether adults were more participatory in mixed-aged classrooms. Results from a faculty questionnaire are also presented, and the educational implications of the findings are discussed. Contains 5 references. (GLR)
