The authors developed a free online course that centers learning about identity, power, positionality, and privilege to support inclusive teaching for STEM faculty and future faculty. Instructors across all institution types, including community college and 2-year, regional and comprehensive, and public and private research universities, utilized and valued a free asynchronous online course with an optional local learning community facilitated by project-trained facilitation teams. Participants were highly engaged in the online course content, rated the content positively, and demonstrated increases in awareness, confidence, and intent to apply inclusive teaching strategies. Outcomes demonstrate that the key features of the course (My Inclusivity Framework, Learning Community and Affinity Group discussions, and Embodied Case Studies) were viewed as unique teaching development opportunities that created valuable learning for our participants.
