Effort: Medium
What to notice
Offer a moment to articulate the reason after an important decision.
Where it fits
- Fits
- Learners practicing the reasoning behind a decision.
- Use it when
- When one brief optional reflection fits the learning task.
- Avoid it when
- When an essay would be imposed during purchase or application.
How to build it
- Keep decision evidence visible.
- Offer an optional one-sentence explanation and a skip path.
- Use a different example to check transfer.
Measure
- Main metric
- Share of eligible learners correctly deciding and explaining a different case
- Guardrail
- Language burden and concerns about storing reflections
- How to measure
- Allocate comparison groups before exposure and use equal follow-up and eligibility. Track Share of eligible learners correctly deciding and explaining a different case alongside Language burden and concerns about storing reflections.
When it backfires
Do not treat length or writing fluency as depth of understanding.
Alternatives
Theory behind it
Self-explanation
Explain why a worked step makes sense rather than merely inspecting it.
Limited evidence
Informational feedback
Explain the gap to a goal and what to change, rather than offering praise alone.
Practitioner framework
Evidence limits: An editorial web application; conversion effects on this interface are unmeasured. Effects depend on feedback type and prior knowledge in educational research. Lengthy advice after every action can add burden.
