  • From Shame to Strength: Supporting ADHD Students. A Discussion with Karen Costa
    Jan 29 2026

    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.

  • Are Students Knowledge Consumers or Co-Producers? A discussion on academic co-creation with Robert Gray
    Nov 6 2025

    In this episode, we sit down with Dr. Robert Gray, Associate Professor of University Pedagogy at the University of Bergen in Norway, to explore a fundamental question about the purpose of higher education: should learning be an act of consumption or production? Maybe the best learning experiences don't simply ask students to absorb information—they invite students to actively re-write and co-create knowledge with the teacher.

    Dr. Gray's research draws on Roland Barthes' concepts of "readerly" and "writerly" texts, arguing that valuable learning happens when students are encouraged to "re-write" their classroom materials and become active producers of meaning. We discuss how students bring diverse perspectives and contexts to shared texts and lectures, creating something new and innovative from the materials we provide. As educators, we are challenged to foster an active, collaborative campus culture where learning becomes genuinely additive and co-creative.

  • “Constitutively Irresponsible”: Why Students Can't Be GenAI's Quality Control. A conversation with Gene Flenady and Robert Sparrow.
    Oct 23 2025

    This week, we have two guests on the podcast. We’re joined by Gene Flenady, Lecturer in Philosophy at Monash University, whose research concerns the structure and social conditions of human rational agency, including the implications of new technologies for meaningful work and tertiary pedagogy. Our second guest is Robert Sparrow, Professor of Philosophy at Monash University. His research interests include political philosophy and the ethics of science and technology with an eye towards real-world applications.

    Flenady and Sparrow argue that GenAI systems are "constitutively irresponsible" because their algorithms are designed to predict what "sounds good" - not necessarily what is true or contextually appropriate. Our guests suggest that it's unfair to expect learners themselves to determine when AI is wrong or misleading. Doing so puts students in an impossible position and gets in the way of building meaningful relationships with their human teachers and the pursuit of lifelong learning.
