Evidence-gated learning memory

These examples and illustrative results are independently authored teaching materials, not measured model results.

Use case

Choose the next lesson after explaining transaction isolation. The teaching learner viewed the lesson but demonstrated only one judgment: repeated reads may differ in a supplied schedule. Other anomalies are untested. Exposure, self-report and demonstrated use are different evidence.

Mechanism

In authorized learning records, distinguish demonstrated use, claimed prior-knowledge depth, corrected misconceptions and covered material. Record the question, evidence and untested scope rather than marking the whole topic mastered. Supersede contrary records with an explicit correction relationship, then choose the next teaching question.

Bad example

The lesson was displayed, so mark transaction isolation fully mastered and skip every related exercise. Leave the record unchanged after contrary answers.

Good example

Record the supplied evidence: the learner correctly identified possible changed results in this repeated-read schedule; other anomalies remain untested. Label prior knowledge as self-reported with claimed depth, not an assessment pass. Select a related untested judgment next. When contrary evidence appears, retain and supersede the old record. Do not equate material coverage with mastery.

Why the change matters

An activity record establishes exposure rather than usable knowledge. Separating demonstrated ability from coverage helps avoid both pointless repetition and advancement past unverified understanding.

Observable expectation

An illustrative record says demonstrated: this repeated-read judgment; untested: other anomalies, instead of mastered isolation. The next exercise targets untested scope. Later misconceptions create a supersession marker.

Trace each conclusion to an answer or explicit self-report; advancement based on display alone fails.

Limits

One correct answer may depend on hints, guessing or familiar questions, so preserve scope. Self-reports help avoid repetition but are not independent assessments. Follow the teaching environment’s storage authorization instead of saving private learner data without permission.
