HCD.6.1:4.2.2 - Learn a family of regularities without forcing a single rule

Use several examples when a target distinction depends on combinations, timing, context or probabilistic regularities that one pair cannot expose. A natural-language expression may be appropriate in one register and awkward in another; a style may be recognizable through several relations that no isolated feature uniquely identifies. First establish the intended use and the source of qualified examples. A collection chosen for one speaker, teacher or archive can distort the family the learner will later encounter.

Start with examples the learner can meaningfully encounter. Make the context available, including the preceding phrase, action or response when that changes interpretation. Ask for a discriminating contribution: select a likely continuation, match an utterance to a situation, imitate and vary a phrase, respond to a partner, or compare two performances. Supply feedback in a form the learner can use even when a complete verbal rule is unavailable.

Use errors and uncertainty to choose informative comparisons. Put a confusable case beside a clear one; preserve a contextual condition that makes the difference intelligible. Then return to varied examples where the learner must recover that difference among other features. Purely isolated contrasts can make a cue easy to detect while leaving it unavailable in ordinary performance. Conversely, an undirected stream of material can leave the same confusion untouched. Combine broader exposure with focused returns where they make a useful difference.

Choose variation on two grounds: representation of the receiving practice and resolution of a present confusion. Include familiar, uncommon and changing forms according to that purpose. Distinguish an exception to the learner’s provisional generalization from a different accepted convention or a defective example. A rare form need not be learned to the same automaticity as an everyday one; a reliable reference or a timely request can be the better contribution.

Do not equate a distribution in teaching material with a rule of the culture. When the material intentionally balances two alternatives, explain that balance if it could mislead expectations about ordinary use. When judgement is graded or contested, preserve more than a forced binary answer: ask which use is more fitting under the stated purpose, what remains uncertain and how a competent participant would respond.

After a response becomes reliable on familiar material, try the relevant change of speaker, phrase, partner or context. Keep the target judgement distinct from the ability to produce the same pattern. Select further encounters when they can improve the needed response or resolve an important uncertainty; exhaustive coverage of the culture is not the completion condition.
