HCD.9:2 - Problem

The common shortcut is “more practice.” It treats duration or repetition as the intervention while leaving the target action, provider, information content, task variation, and next observation unspecified. A learner can repeat the same error, receive only a score, or become better at the displayed answer.

A second shortcut records only the corrected product. This removes evidence of the first error and the support that produced the repair. It can make a teacher’s demonstration or AI output look like independent learner performance.

A third shortcut retests everything after one defect. It wastes already supported results, hides the precise difficulty, and may not fit the promised time. Conversely, passing an unrelated total score can conceal a critical error that still needs correction.
