Dead Ideas in Teaching and Learning is a podcast from the Columbia University Center for Teaching and Learning. Our mission is to encourage instructors, students, and leaders in higher education to reflect on what they believe about teaching and learning.

The Myth of the One-Size Fits All CTL with Chris Hakala
Chris Hakala, director of the Center for Excellence in Teaching, Learning, and Scholarship (CETLS) at Springfield College, joins us this week to dismantle a persistent myth about centers for teaching and learning. With over 30 years in faculty development, assessment, and the study of student learning, Hakala challenges the dead idea that a CTL’s job is to simply hand faculty a fixed set of best practices about student learning. Instead, Hakala argues that fixed practices don’t always meet faculty where they are or reflect the realities of a given academic discipline. Particularly in the age of AI, the most effective CTLs are grounded in evidence-based pedagogical theory while remaining adaptive and creative in their recommendations on how those theories can be expressed in a given classroom. CTLs can and should recognize that every school, department, and discipline will need a customized approach to student learning.

You Must Remember This: Memorization is Just a Scaffold… as the Semester Goes By with Tommy Lee
Dr. Tommy Lee, a behavioral neuroscientist in Barnard College at Columbia University’s Department of Neuroscience and Behavior, joins Dead Ideas in Teaching and Learning to challenge one of higher ed’s most persistent assumptions: that memorization is a low-level task standing in the way of real learning. Dr. Lee’s research considers how the brain forms episodic memory, including our memories of experiences and spaces. In this episode, we tackle the dead idea that remembering and thinking are opposites. Lee complicates this notion by drawing on his own research into the hippocampus and other studies on working memory, disproving the notion that memorization crowds out critical thinking. Lee argues that as AI agents make it easier to “just look up info,” this dead idea is again becoming pervasive in higher education. We end the episode with practical guidance for instructors looking to build retrieval practice into their coursework. The end result is a classroom that lowers the stakes for students, reduces their anxiety, and makes progress more tangible. Recommended Readings / References: Lee, S. L. T. (Forthcoming 2027).

UDL at Scale: Designing Learning at the Institutional Level with Thomas Tobin
Thomas Tobin, one of the foremost voices on Universal Design for Learning (UDL), joins us to preview his forthcoming book, UDL at Scale: Whole-Campus Universal Design for Learning. Where his earlier work made UDL manageable for individual instructors, Tobin's new publication asks what happens when an entire campus — including administrators — advocates for and values universal design. Tobin first joined the Dead Ideas in Teaching and Learning podcast to discuss inclusive teaching in 2022 (listen to "Student Perceptions of Instructor Authority and Inclusive Teaching"). In this episode, we tackle the dead idea that learners make impartial, rational decisions about how they learn best. Tobin complicates this notion by sharing a contemporary example: students' increased reliance on AI to bypass the fundamental building blocks of learning. He argues that students will thrive as co-designers of learning only when UDL supports underlie those classroom experiences. UDL is only effective when it is possible, permitted, supported, rewarded, and expected across an educational institution at the faculty, student, and administrative levels.
