Book, Engagement, And New Role
- Ollie wrote his book during COVID while engaged and moving schools.
- He joined Brighton Grammar with a researcher role in their Crowther Centre focused on sharing research.
When To Rely On Writing Versus Memory
- Writing eases immediate working-memory load for short problems, while long-term learning needs automation in long-term memory.
- Use writing for momentary problem-solving and practice retrieval to build lasting fluency.
Productive Struggle Versus Cognitive Overload
- Distinguish productive struggle from overload by reducing extraneous load and sequencing curriculum to optimise intrinsic load.
- Ensure students think about the intended material and avoid tasks that force cognitive effort on irrelevant elements.
