880 Eyeballs: Mastering Active Learning in Large Classes with Justin Shaffer
Dead Ideas in Teaching and Learning
What practical strategies enable active learning in large lectures?
Justin shares tactics: short pauses, think-pair-share, polling/clickers, pivoting with data, and scalable assessment methods.
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.
