The historically distinct fields of adult and higher education are converging in a dramatic demographic shift from undergraduate classrooms occupied primarily by traditional-age college students to ever-increasing numbers of adults within baccalaureate programs. This study found that while higher education faculty acknowledged that adult students differ from their traditional-age counterparts and enhance the overall educational environment in mixed-age undergraduate classes, they perceived no need to adapt their instructional approach to accommodate this growing postsecondary demographic. These findings reveal a lack of understanding by the professoriate regarding adult learners and adult education methodologies, and they provide valuable insight into an emerging crisis in America's college classrooms where faculty members are increasingly unable to meet the needs of today's learners. Amid the clamor for accountability in higher education, the results and context of this study provide direction for future discussions and implications for adult higher education praxis.
