Restudy decision protocol
Use a defined decision rule — not a feeling — to determine which items get additional study.
Key takeaways
- What it is: Use a defined decision rule — not a feeling — to determine which items get additional study.
- Why it works: JOLs influence restudy decisions: learners drop items they rate as learned and spend more time on items they rate as not learned. When JOLs are inaccurate, this allocation is counterproductive — easy, familiar items get over-studied; hard items that generate low JOLs but are still above the retention threshold get abandoned. A defined protocol decouples the restudy decision from fluctuating feelings and ties it to objective performance criteria.
- Evidence: Plausible mechanism, limited direct outcome data.
- Avoid: Dropping an item from restudy after a single correct recall, when the item is accessible now but has not been tested at a delay — producing a one-hit wonder that will fail at retention.
Why it works
JOLs influence restudy decisions: learners drop items they rate as learned and spend more time on items they rate as not learned. When JOLs are inaccurate, this allocation is counterproductive — easy, familiar items get over-studied; hard items that generate low JOLs but are still above the retention threshold get abandoned. A defined protocol decouples the restudy decision from fluctuating feelings and ties it to objective performance criteria.
How to do it
- 1Define your threshold: an item is ready to drop only if it was recalled correctly without prompting on two non-adjacent tests.
- 2Apply the threshold uniformly — do not override it because an item "feels solid."
- 3Review dropped items at a defined interval (one week) to verify retention.
- 4Reinstate dropped items that fail the retention check without changing the threshold.
What the evidence says
MechanisticRestudy allocation research shows that criterion-based dropping rules outperform JOL-based dropping in producing long-term retention, because they prevent premature withdrawal from items that feel familiar but are not durably encoded.
Honest caveat: Formal criterion-based protocols are studied in controlled lab settings; the specific threshold ("two correct recalls") is a practical guideline, not a universally tested value.
Common mistake
Dropping an item from restudy after a single correct recall, when the item is accessible now but has not been tested at a delay — producing a one-hit wonder that will fail at retention.
IX Coach applies a two-pass criterion automatically before retiring any item from active review, overriding your in-session feeling that you are done with something.
