This case study examined student preference for delivery mode of online courses in two graduate degree programs in Library and Information Science. Within-group and between-groups comparisons indicated a distinct preference across the institutions. Findings from focus groups conducted with two cohorts of students enrolled in a federally funded project indicated students preferring asynchronous delivery enrolled in such courses to accommodate busy lifestyles. In the synchronously deployed course, flexibility in accommodation of various learning styles was evidenced by such influential factors as teaching style, instructional design, and topicality. Findings inform online education for modality and instructional style.
