He discusses shifting from unguided projects to explicit instruction and the instructional hierarchy. Short fluency practice, scaffolded fading, and designing tasks backward from goals are highlighted as keys to enabling those aha moments.

Episode notes
Career Pivot Sparked Instructional Reappraisal
- Brendan left teaching, opened a café, then returned to primary teaching after seeing disengaged Year 7 students.
- That pivot sparked deep learning about instruction and prompted him to question project-based defaults and seek evidence-informed approaches.
Instructional Hierarchy Maps When To Guide
- The instructional hierarchy (acquisition, fluency, generalization, adaptation) gives observable stages to place students and guide instruction.
- Using fluency assessments like DIBELS maps students onto that hierarchy and shows when explicit scaffolding or fading is needed.
Fade Prompts Instead Of Overprompting Independence
- Avoid overprompting at release to independent practice; fading prompts too slowly steals students' chance to practice independently.
- Brendan notes last-minute reminders are powerful prompts that prevent genuine independent application and retention.
