The document describes the development of an Online Course Design Checklist (OCDC) intended to simplify the online course design process for instructors. It was created by distilling important elements from existing course evaluation instruments and instructional design research into a single-page checklist. The checklist highlights criteria that should be considered before, during, and after online course design. Nineteen current and prospective online instructors provided feedback on their perceptions of using the OCDC. Participants found that the OCDC facilitated online course design by providing criteria to consider at different stages of the process.
