Episode notes
Mass School Visits Sparked The Book Series
- Craig Barton spent 2–3 years visiting hundreds of maths departments and watching over a hundred lessons each month.
- He used those visits to distil common patterns and then wrote 16 focused books to share what he learned.
One-Off Fixes Rarely Change Practice
- Many teaching problems require sustained, iterative support rather than one-off fixes.
- Craig shifted from repeated school visits to writing books because the same issues recurred and needed long-term change.
Include Only Proven, Replicable Techniques
- Only include classroom strategies you've seen work at least three times in different schools.
- Test ideas across varied contexts to avoid relying on a single superstar teacher's success.
