As online education continues to grow, instructors from traditional classrooms are being asked to design online courses. In this study, data from interviews with thirty-three public four-year college and university instructors, who had experience designing online courses, were used to understand the instructor's perspective on online course design. Using grounded theory, data were analyzed, sorted, and coded to uncover the strategies instructors use to design online courses. Results revealed instructors adapt to the online environment by using strategies to mimic elements of face-to-face courses: in essence, adaption comes through assimilation. Instructors expressed interest in helping students navigate online to encourage active participation in courses. They described using technology and learning management system (LMS) features (e.g., videos, discussion forums) to "hear" and "see" students, as a way to increase interaction and presence, familiar elements from face-to-face education. They spoke of creating authentic assignments to increase student engagement. The implications of this study include effective design and instructional strategies for online courses, as well as understanding the motivation of instructors who design online courses. The study results are relevant to a broad audience including online instructors, instructional designers, LMS organizations, and administrators.
