HCD.5:4.2.1 - Compose learning from the contribution, not an explicit–implicit ratio

Use this branch when a rule lesson, repeated imitation or unstructured participation leaves a person unable to use what they encounter. The aim is a feasible combination in which each activity supplies something the next contribution needs. The combination can begin with an explanation, a demonstration, an existing successful performance or participation in work; the entry evidence decides.

Recover the practice and the kind of judgement. Identify the receiving activity and an adequate performance, together with a nearby case that calls for a different response. Correctness can be specified by a rule, but it can also be made accessible through recordings, competent demonstrations, accepted work products, partner responses or qualified practitioner judgement. Establish the conditions in which those comparisons have standing. Where competent practitioners differ, preserve the different conventions or purposes and teach a useful choice between them. If the required distinction remains unsupported, narrow that target or obtain subject help. Incomplete verbalization alone does not make a demonstrated practice unavailable.

Distinguish a learner’s ability to explain a regularity from their ability to notice, anticipate or enact it. Likewise distinguish a teaching activity from a claim about the learner’s psychological mechanism. Learning from examples can include deliberate comparison; a fluent response can have a history of explicit instruction. Failure to verbalize an acquired distinction does not establish that its acquisition was unconscious. Neural-network learning can suggest questions about exposure, variation or prediction, but that analogy supplies no evidence of the human mechanism.

Find the missing contribution in an attainable whole use. Use an existing work sample or a small supported encounter, rather than demand an unaided test from someone who cannot yet enter the task. Ask what the person can already supply and what the current help supplies. Then choose the contribution that will change the next attempt:

Choose what to explain and when to bring it into attention. Explain a relation when it can make the next action intelligible, expose a misconception, protect a consequential boundary or help transfer. Demonstrate or contrast what a description leaves imperceptible. During a difficult whole performance, one usable cue may serve better than simultaneous monitoring of every component. Inspect a detail between attempts, practise it under manageable conditions, then let the learner return attention to the purpose, partner or result of the whole. If conscious monitoring already helps, keep it. If it disrupts an otherwise available coordination, compare a different cue or a separate preparation episode. The appropriate focus is a subject- and learner-dependent design choice.

Build a distribution of encounters, not only a rule and one exception. Frequent forms can deserve repeated use; rare but consequential exceptions can deserve deliberate contrasts or an available reference. Include meaningful variation in speakers, situations, materials or partners where later work will require it. A teaching set may intentionally overrepresent a difficult exception. Tell the learner enough about that choice to avoid mistaking exercise frequency for prevalence in the practice. There is no universal proportion of rule-governed and example-based learning, including a 70/30 split. Allocations of time should follow the missing contribution, encounter opportunities, consequence and response.

Distinguish learning a convention, switching conventions and changing one. For reproduction, provide examples and feedback from the practice the learner wants to join. For switching, contrast situations with different purposes or expectations and practise recognizing which convention is in use. For deliberate innovation, let the learner vary a consequential relation while retaining a chosen contribution, then examine the variant with competent participants in its receiving use. A successful experiment can support keeping that variant locally; wider adoption and a changed cultural norm are further results. Music and dance practice development returns those questions to MDPE.21/.17 and Application:5. Learning to take part in that work remains an HCD question.

Join activities through actual use. An explanation can supply a distinction for comparing examples. A contrast can make an instruction perceptible. Repetition can make a response available quickly enough to coordinate with another action. Participation can expose the context or exception that changes the next explanation. State which of these joins is needed here and give the learner the corresponding action. Do not add all activities to every lesson or presume a one-way progression from theory to practice.

Choose the next observation from the pending decision. If learners can recognize the pattern but cannot enact it, change practice rather than add more recognition questions. If they perform only with a model, decide whether that support belongs to later work or whether another occasion should expose selection without it. If their response fits one register or partner convention, extend the experience only when another use is needed. Stop the added development when the supported arrangement serves the present purpose.

This construction is a reasoned teaching hypothesis. Use established subject knowledge, available observations and current learning research to choose a worthwhile action; an unattainable controlled experiment is not a prerequisite for trying a proportionate arrangement. Retain what is uncertain when it changes use. Commission a further comparison when its attainable answer can change the teaching choice or justify a stronger claim enough to warrant its cost. C.11.DUA develops that comparison; it neither converts a plausible mechanism into a demonstrated effect nor requires a study merely to finish this design.
