Technological advancements and lower production costs since the mid-1990s have dramatically improved opportunities for instructors to tailor self-made instructional videos for their students. However, video production technology has outpaced the development of educational theory, causing instructional videos to consistently fall short of their pedagogical potential. Responding to these shortcomings, scholars from various backgrounds have started publishing guidelines to help practitioners as they develop instructional videos for their respective fields. Using a rapid literature review, this article contributes to this ongoing effort by synthesizing theory-based, best-practice guidelines for a specific subcategory of educational videos called supplemental instructional videos (SIVs). SIVs are different from other types of instructional videos in that they are used to support and magnify other learning methods, mediums, and materials rather than substitute for them. Bringing the best-practice guidelines synthesized in this paper immediately into application, they were used to inform the production of SIVs for an undergraduate course that was held in the Building Construction Department of a major public university in the United States during the Spring 2020 semester. The methods used in the production of the SIV guidelines were systematically documented during the course for future researchers and practitioners to learn and build from.
