What Classrooms Reveal About Designing Better Work | Peter Liljedahl, Revisited
Tue Feb 03 2026
After decades in education, Dr. Peter Liljedahl realized that many classrooms fail to engage the people inside them. Rather than accept that reality, he began challenging every classroom norm he could find, asking a single question of each one: does this increase thinking?
What followed was a decades-long effort to redesign learning environments from the ground up, dramatically increasing student engagement and understanding. In this revisited episode, Dart and Peter discuss how rethinking classroom norms can reshape learning, collaboration, and the design of work itself.
Dr. Peter Liljedahl is an author, researcher, and professor of mathematics education at Simon Fraser University in Vancouver, Canada. His work focuses on increasing thinking, engagement, and collaboration through classroom design.
In this episode, Dart and Peter discuss:
- Peter’s redesign of the classroom and how it can be applied to work
- How to create an environment that cultivates thinking
- Transforming norms to achieve better results
- The importance of collaboration in work and learning
- The best ways to evaluate employee performance
- Deconstructing ideas into actionable points
- What creates “Aha!” moments
- The structure of a good task
- And other topics…
