#206: Why Do Innovative Teachers Go Back to Traditional Instruction? Bob Lenz on PBL and the Systems That Pull Them Back
Episode Summary What if the scripted curriculum we hand new teachers is the very thing burning them out? In this episode of Coaching the Whole Educator, Becca Silver talks with Bob Lenz, CEO of PBLWorks, about how project-based learning (PBL) helps early career teachers thrive instead of just surviving, and why school systems built for consistency keep pulling innovative teachers back into compliance. Bob shares findings from a randomized controlled trial of the Knowledge in Action AP curriculum, where PBL students outscored peers on AP exams by 8% in year one and 10% in year two, across all demographics. He explains why teachers trained in student-centered schools often revert to traditional instruction within three years of moving to a traditional school, and why giving new teachers high-quality PBL curriculum acts as a “floor,” not a script. Becca connects the conversation to her resistance work, naming the compliance culture that shapes how we treat both students and adults. In this episode, you’ll learn: Why the portrait of a graduate works as a “Trojan horse” for deeper learning and PBL adoption The biggest gap between teacher prep programs and day one in the classroom How PBL partner districts improved chronic absenteeism (one middle school went from 66% to 96% attendance) The four areas leaders need to address for systemwide PBL: vision, conditions, professional learning, and measurement Why “two projects a year” is a realistic starting point for reluctant departments How making expert thinking visible builds new teacher agency and confidence Why PBL is an equity issue, and why it may be less “innovation” than overdue updating Who this episode is for: instructional coaches, principals, district leaders, and teacher leaders supporting new teachers, implementing project-based learning, or working to reduce teacher burnout and turnover. Frequently asked questions Does project-based learning improve test scores? According to Bob, a randomized controlled study validated by USC found PBL students scored 8 to 10% higher on AP exams than students in traditional classes, with strong gains in critical thinking and communication. How can schools support new teachers with PBL? Pair high-quality, student-centered curriculum with embedded professional learning and coaching, so new teachers start from a strong floor instead of designing units from scratch on Sunday night. Why do innovative teaching practices fade? When school policies, pacing, and observation practices conflict with student-centered goals, teachers drift back to compliance-based instruction. Leaders have to surface those conflicts and build a coherent system.
