The Feynman Technique
Explaining an idea simply exposes unclear language, missing steps, and borrowed phrases. If the explanation breaks, you found the place to learn.
The learning method
TeachBack is designed around a simple test: can you explain the idea clearly, in your own words, without leaning on the page?
Why this approach
Explaining an idea simply exposes unclear language, missing steps, and borrowed phrases. If the explanation breaks, you found the place to learn.
Pulling an idea from memory is different from recognizing it on a page. That effort is what makes the check useful.
Repeated attempts to retrieve material can support longer-term retention better than another passive read-through.
Returning to a concept later helps reveal whether it is truly available from memory, not only fresh from the last session.
The complete loop
Bring in a planned photo, PDF, lecture outline, or pasted notes. TeachBack identifies concepts without turning the source into a replacement answer.
TeachBack pulls out the concepts that matter.
Key definitions, steps, relationships, and likely edge cases become the checklist for your explanation.
Use your own words. Pause, restart, and mark confusing moments as they happen.
The planned evaluation looks for concept coverage, accurate reasoning, useful examples, and missing constraints.
Instead of a generic summary, you receive a short list of what to re-teach and why it matters.
✓ Core idea explained
✓ Correct example used
✓ Good causal reasoning
↗ Limiting case skipped
↗ Mixed two terms
↗ One formula recall
A 7, 14, or 21-day plan schedules focused work and brings weaker concepts back into view.
Responsible research
TeachBack applies established retrieval-practice and self-explanation principles. Outcomes depend on the learner, material, context, and consistent use.
Roediger and Karpicke found stronger delayed retention after retrieval practice than repeated study in their experiments.
Open source ↗2013 · PSPIDunlosky and colleagues reviewed ten learning techniques and rated practice testing and distributed practice as high utility.
Open review ↗Statistics and summaries are drawn from the cited studies. TeachBack AI applies retrieval-practice principles. Individual results vary, and TeachBack does not promise specific grade improvements.
