This article explores the design and development of a Massive Open Online Course (MOOC) on inclusive teaching. Released in the Fall of 2023, the MOOC is particularly unique because of its intentional use of ethnically diverse voices and multimodal content to include art, music, spoken word, and storytelling. Modules range from Self and Empathy to Classroom Climate and Networks. MOOC production was graciously funded by a grant from the Howard Hughes Medical Institute. At its core, the article will share reflections on the rationale and process, describe how STEM and Adult Education scholar-practitioners collaborated to infuse adult education and interdisciplinary concepts in MOOC development and outline meaningful implications for the field.
