HCD.9:4 - Solution

Bind one representative task to one practice focus. Preserve the first attempt and its actual support conditions, observe the changeable action, provide criterion-bearing feedback at a risk-appropriate time, obtain the learner’s correction, and retry the affected requirement under conditions that can expose the intended change.

HCD.9:4.1 - Bind the Episode before the Attempt

State:

1. the human holder, later-Work target, selected HCD.5 Method, HCD.6 task, and receiving development decision;
2. the practice focus, observable action, required result, domain criteria, protected errors, and useful uncertainty;
3. the task condition that makes the action necessary and one condition that could change the warranted move;
4. permitted sources, tools, AI, peer, teacher, specialist, time, prompts, demonstrations, and other help from HCD.7/HCD.8; and
5. the feedback provider, safe intervention point, correction opportunity, retry boundary, and stopping condition.

If the task, criterion, provider, access, or correction opportunity is missing, return that exact gap. Do not spend the episode and call the resulting exposure practice.

HCD.9:4.2 - Preserve the First Attempt and Actual Help

When independent action is part of the purpose, obtain and preserve the learner’s response before an answer-bearing cue, demonstration, correction, or generated solution. Record the condition, elapsed time, sources opened, tools and AI used, questions asked, prompts supplied, peer or teacher intervention, and the point at which each contribution arrived.

A supported first attempt is legitimate when support belongs to the intended task. Name it as supported. If safety or consequence requires the provider to interrupt before completion, preserve the last safe action and reason for intervention; do not manufacture an unsafe independent observation. Intended help, permitted help, available help, and help actually received remain different facts.

HCD.9:4.3 - Observe the Changeable Action

Compare the attempt with the stated criterion and evidence. Locate the smallest action that explains the current difficulty or useful success: the selected source, configuration check, calculation, distinction, causal claim, request, refusal, adaptation, execution, or verification. Preserve uncertainty and plausible rival explanations when the observation cannot distinguish them.

Do not turn one error into a stable trait or broad deficit. An incorrect result may come from the task condition, inaccessible source, support mismatch, misunderstanding, arithmetic, domain knowledge, fatigue, or another factor with different next Work. If that distinction changes the intervention, return to HCD.3, HCD.6, HCD.7, or the direct domain owner before prescribing more repetition.

HCD.9:4.4 - Give Feedback the Learner Can Use

A feedback contribution names:

• the exact requirement or criterion and the observed part of the attempt;
• what remains useful and should be preserved;
• the error, uncertainty, missing check, or unsupported relation that needs attention;
• the smallest cue, question, example, explanation, or correction information suitable for the learner and task;
• the action the learner performs next and the opportunity and deadline for using the information; and
• the provider, channel, timing, support boundary, and any consequence or escalation.

Choose timing from the purpose, risk, and error. Intervene immediately for an unsafe, irreversible, privacy-breaking, or repeatedly rehearsed critical action. When conditions are safe and the first response is informative, allow enough of the attempt to preserve the learner’s reasoning before feedback. There is no universal immediate or delayed timing rule.

A score can locate a threshold and praise can acknowledge effort, but neither substitutes for information about the action when a correction is required. A full solution may be appropriate as a worked example in another episode; if it supplies the current answer, record that the learner’s independent action was not observed.

HCD.9:4.5 - Obtain a Correction and Targeted Retry

Ask the learner to use the feedback: explain the changed relation, revise the action or product, perform the missing check, or state a justified stop. Preserve the correction separately from the provider’s feedback. Then retry the affected requirement.

Use a changed but comparable case when the target includes recognizing applicability, selecting a Method, adapting it, or responding to a decision-bearing condition. Repeating the exact answer may be sufficient only when stable execution of that same operation is the target. Keep requirements already demonstrated unless the new response contradicts them or the changed condition makes them material again.

If several independent gaps cannot be corrected and checked in the available episode, return the unresolved requirements and the smallest additional time, task, provider, or output decision. Do not add hidden practice hours or erase the gap with an aggregate score.

HCD.9:4.6 - Decide the Episode Outcome without Overclaiming

Use one of these bounded positions:

• changed action under recorded conditions: the retry shows the intended correction or discrimination with its actual support;
• unchanged or recurring difficulty: the same relevant error remains after usable feedback and a valid retry;
• new or differently located difficulty: the retry changes the diagnosis or exposes another dependency;
• safe stop or incomplete episode: risk, missing access, provider failure, time, or task invalidity prevents a truthful retry.

The first position is a useful local practice result, not proof that feedback caused the change or that capability will appear independently, transfer, or persist. Route those interpretations to their direct Methods. The other positions can change the next Method, task, support, or practice focus without declaring the learner generally incapable.

HCD.9:4.7 - Return the Practice-Episode Result

An HCD.9 result contains:

Preserve the trace at the resolution needed by the next decision. Do not require one record per pattern when one complete task tests several connected Methods, and do not merge distinct first, helped, corrected, transfer, or delayed attempts into one score.

HCD.9:4.8 - Recognition and Assurance

Recognition. Use HCD.9 when a learner is about to practise or has produced a result, but the practitioner cannot yet point to the first attempt, actual help, feedback-bearing action, learner correction, and next retry. “Completed,” “received feedback,” and “improved” are warning labels when those facts are missing.

Assurance. Stronger reliance needs a representative task, qualified criteria, preserved support conditions, a safe first-attempt boundary, feedback with usable information, a learner-authored correction, a valid retry, and a conclusion limited to the observed conditions. High-consequence errors need direct domain and authority owners; HCD.9 supplies no final employment, authorization, release, transfer, or retention decision.

HCD.9:4.9 - What Changes in Practice

A practitioner stops asking, “How many hours did the learner practise?” and asks, “What did this person try under which help, which action did the feedback address, what did the person change, and did a comparable retry expose the corrected move?” The next episode follows the remaining difficulty rather than a generic demand for repetition.
