The science behind it: Prior Knowledge as Foundation
All new learning rests on what you already know; richer, more accurate prior knowledge makes subsequent learning faster, deeper, and more transferable.
Why it matters
When prior knowledge is thin, learners hit a wall that effort alone cannot break; investing in foundational knowledge unlocks later topics.
How to apply it
- Before tackling a new topic, map what you already know and identify the prerequisites you are missing.
- Spend deliberate time on prerequisites even when they feel elementary.
- Use reviews of old material to refresh the schemas new topics will attach to.
Common mistakes
- Skipping basics because they look obvious.
- Pushing into advanced material with a shaky base, leading to fragile understanding.
- Ignoring the cost of forgotten prerequisites from earlier courses.
