    From Shame to Strength: Supporting ADHD Students. A Discussion with Karen Costa

    Welcome to Season 11! In our opening episode, we sit down with Karen Costa, a faculty development facilitator specializing in online pedagogy, trauma awareness, and course/community design. Our conversation focused on her forthcoming book, An Educator's Guide to ADHD: Designing and Teaching for Student Success, to be published in January 2026.  In this conversation, Karen challenges educators to rethink how we frame ADHD in the classroom. In reframing ADHD as a normal variant of the human experience rather than a disorder to be corrected, we can avoid ableist language that undermines our pedagogical aims in the classroom. Karen also shared practical strategies for supporting ADHD students, including offering multiple assignment formats and providing clear task lists and deadlines. Both of these approaches strike a delicate balance between creative freedom and helpful constraints in course design. Throughout our discussion, Karen reminds us that reducing shame in the classroom and celebrating students' diverse strengths may be the most powerful tools we have as educators.

    880 Eyeballs: Mastering Active Learning in Large Classes with Justin Shaffer

    Can you truly engage students in active learning when facing hundreds of faces in a lecture hall? We explore this challenge with Justin Shaffer, Founder of Recombinant Education, Associate Dean for Undergraduate Studies, and Teaching Professor in Chemical and Biological Engineering and Quantitative Biosciences and Engineering at the Colorado School of Mines. Dr. Shaffer shares insights on managing the intensity of teaching to "880 eyeballs" and reveals how highly structured course design transforms large classroom experiences. Together, we examine backwards design principles, effective assessment techniques, and practical classroom activities that enable educators to foster deeper student learning, even at scale. Learn more about Dr. Shaffer’s work in his publication - High Structure Course Design. Other materials referenced in this episode include: S. Freeman, S.L. Eddy, M. McDonough, M.K. Smith, N.
