HCD.10:4.9 - Recognition and Assurance

Recognition. Use HCD.10 when the next instruction is “make it harder,” “space it,” “mix the topics,” “test retrieval,” or “remove the help,” but the target discrimination, timing relation, source condition, support state, or response rule is missing. The warning sign is a bundled schedule whose failure has no unique interpretation.

Assurance. Stronger reliance needs prior attempt evidence, one target contribution, representative tasks, explicit decision-bearing changes, separated times for spacing, separate retrieval/source/support choices, task-similarity grounds for interleaving, conditional challenge progression, direct risk owners, and an observation with a lowering rule. A scheduled visit or hard task establishes no transfer or retention by form.
