Episode notes
Research Skeptic Turned Careful Tester
- Andrew explains his habit of checking research claims before accepting them and protecting teachers from overbearing mandates.
- He started skeptical of PBL but investigated a study and found it more convincing than expected.
PBL Can Succeed Without Overloading Working Memory
- Andrew found a PBL study that held up better than he expected and showed modest positive effects over a school year.
- The study undermined his specific worry that PBL necessarily causes working-memory overload.
High-Quality PBL Is Layered, Not One-Size-Fits-All
- Fox describes effective PBL as layered: build content, add inquiry, then provide explicit instruction and feedback as needed.
- Implementation often degrades from published intent when systems aren't in place to support it.
