This research describes course design elements most valued by adult learners in blended learning environments that combine face-to-face contact with Web-based learning. It identifies the online course features and the instructional design goals selected as most important by a sample of 67 adults and compares the group rankings with those of various sub-groups based on gender, pre-course technology and self-direction skills and experiences, and preferred learning strategies as measured by Assessing the Learning Strategies of Adults (ATLAS). The results of the study support the principles of adult learning, indicating that adults value course designs containing options, personalization, self-direction, variety, and a learning community. Findings also identify some differences in learning emphasis by gender, preferred learning strategies, and previous experience with technology and self-directed learning. Implications of these findings for higher education in serving adult learners are discussed.
