Episode notes
How Carl Keeps Writing
- Carl described his blogging rhythm: idea generation, hard middle work, then satisfying editing.
- He spends hours reading research feeds and writes daily to keep a steady writing practice.
Memory Is Reconstructive
- Memory is reconstructive, not like a file drawer, so retrieval updates and alters memory each time.
- This reshapes instructional design: focus on repeated retrieval and durable encoding instead of one-off memorable lessons.
Engagement Isn’t Learning
- Engagement is a poor proxy for learning because students can be busy without thinking hard.
- True learning requires cognitive effort, not just entertaining or high-energy activities.
