HCD.22:4 - Solution
HCD.22:4.1 - Keep the whole work question and choose the dependence
Use HCD.6’s qualified task result, domain criteria, meaningful conditions, critical errors and permissible help. Retain the purpose and recipient of the work result so that fragments do not become arbitrary puzzles.
Choose the dependence that serves the intended operation:
| Dependence | Useful construction | Characteristic failure and repair |
|---|---|---|
| Different evidence or information | Participants interpret distinct relevant observations and make them usable for a joint inference. | A person reads a fragment verbatim without understanding it, or a missing fragment blocks everyone. Require its implication and restore the missing qualified content. |
| Different interpretations or grounds | Participants compare defensible rival models, objections or solutions against common conditions. | A vote replaces examination. Require the condition and evidence that support or defeat each option. |
| Complementary work parts | Several contributions must be integrated into a result whose interfaces matter. | Each learns only their assigned fragment although everyone needs the whole. Add the required cross-part explanation or later task, or narrow the target explicitly. |
| Shared equipment or action | Participants perform useful observer and operator actions around a limited resource. | Observation is empty or substitutes for required manipulation. Specify the observer’s judgement and provide the necessary personal turns. |
| Explanation to a recipient | A learner must make a relation intelligible enough for someone else to use, and respond to that person’s question. | Fluent speech is accepted without recipient use. Ask the recipient to apply or distinguish the relation and return the actual difficulty. |
Several dependencies can coexist, but each adds work. Do not manufacture secrecy, delay or scarce access merely to make collaboration unavoidable. If all needed learning actions are better supported individually, return that result to HCD.20.
A common answer is required only when it contributes to the purpose. Participants can profitably contrast their own models and revise them without creating a separate team report. Where a common result matters, define how it must use the constituent contributions.
HCD.22:4.2 - Make each required action consequential
For each learning target, identify a visible action and the result another action can use. A diagnostic participant might propose rival causes, interpret a measurement, question an assumption or choose a discriminating observation. A second participant must use that contribution in comparing the models, not merely acknowledge that it was spoken.
Allocate actions across preparation, interaction and later attempts. Rotating the role name alone does not rotate the action: a new “analyst” must perform analysis rather than read the previous analyst’s conclusion. A recorder can have a genuine learning target if they reconcile inconsistent claims or preserve the conditions of a conclusion. Copying notes does not establish model selection.
Choose a personal first attempt when the learner has enough preparation and the initial judgement matters for diagnosis, comparison or protection from premature copying. Preserve it before feedback so a later correction can be interpreted. When the learner first needs a demonstration, supply it, then select a subsequent task that exposes the intended action without the demonstration’s decisive cue.
At shared equipment, a non-operator can predict, identify a mismatch, choose a pause or measurement, and explain a consequence. Arrange rotation and later personal execution for actions that require control. Determine how the result is observed without making unnecessary written reporting displace the physical or interpersonal work.
If the purpose includes learning to review or explain, a supplied AI critique or explanation cannot count as the learner’s own performance. It may be a contrast or support. Specify what the person must judge, change or explain and what observation would distinguish that action.
HCD.22:4.3 - Choose visibility and personal memory separately
Decide what participants can see at each useful point: raw observations, reasons, candidate answers, a common model or feedback. Explain what that access enables. A hidden answer can preserve an initial judgement; a shared diagram can make a relation available for simultaneous examination. Neither constant visibility nor repeated isolation is universally preferable.
Decide separately whether personal work is retained and how it can be reused. A saved initial answer helps identify revision but may also anchor later search. If a new attempt is meant to expose a fresh model choice, state which previous material remains a legitimate reference. Do not describe the attempt as uncued after showing the decisive choice.
Bernstein, Shore and Lazer’s experiment distinguishes exposure to others’ solutions from storage of one’s own best solution. It motivates treating these as separate design choices. The experiment concerns triads solving a travelling-salesperson problem and different measures of solution quality; it does not prescribe a visibility schedule for this diagnostic lesson or demonstrate later personal transfer.
After interaction, make needed qualified content accessible to everyone who must use it. Temporary distribution can prompt exchange; permanently withholding another participant’s portion can prevent the later whole-task performance.
HCD.22:4.4 - Connect activities through usable material
For each transition, identify the actual produced content, any transformation, the recipient and what that recipient will do. This can be brief when the interface is obvious; it must be explicit when it determines whether the next activity is possible.
For example, “annotate before the meeting” leaves the central connection unspecified. A useful annotation identifies the claim, its relevant evidence, the proposed interpretation and the question left open. Before the meeting, the assigned recipient can access those annotations and choose incompatible interpretations for comparison. During the meeting, participants resolve or preserve the disagreement in a result the next task can use.
A shared board must preserve source and condition where their removal changes the inference. Compressing “consistent with resistance if flow and efficiency are unchanged” to “resistance” destroys the basis of the comparison. A summary may simplify presentation while preserving that condition.
Provide a recovery path for absent, late, inaccessible or wrong material. Use a qualified prepared substitute, a viable reassignment, additional explanation or postponement within the learner’s route. Preserve the missing person’s opportunity to perform the intended action later. Giving the group the missing correct result can restore the group task without supplying that person’s learning.
Check the real transfer when the activity changes medium, group or time: one person’s private notes may not be shareable; a screenshot may be unreadable; a report may omit the disputed observation. A calendar event and a submitted file do not establish that the recipient received a usable contribution.
HCD.22:4.5 - Select a coherent variant and adapt its working mechanism
Two established designs illustrate different dependencies.
Team-Based Learning. The official account connects preparation, individual readiness work, a team response to the same questions, immediate feedback, appeals and instructor clarification with application to a significant common problem requiring a specific choice and simultaneous reporting. Its purpose is not simply sitting in teams. If borrowing only the comparison of individual and team reasons, describe that adaptation and supply its needed preparation and feedback; do not imply implementation of the whole design. Fixed membership and assessment practices in the source are properties of that design, not rules for all HCD tasks.
Jigsaw. The official account distributes parts, uses expert-group preparation and rehearsal, then returns participants to teach their home groups, with individual assessment. The expert’s contribution is therefore something others must be able to learn and use. In an adaptation, prepare a way to restore an absent or mistaken part and test the recipient’s use. Simply dividing a report into sections omits that teaching dependence. The source’s illustrative group size is not a size criterion for another task.
For either variant, state what has changed, why the learning mechanism remains plausible, and what must be observed in the new setting. Avoid combining labels whose timing, preparation or feedback assumptions conflict. Another construction, including active shared-equipment work, can be more suitable.
HCD.22:4.6 - Make disagreement and feedback lead to another action
Specify how a participant supports a claim, requests clarification, tests a rival and changes a conclusion. A useful challenge names the condition or evidence that would make the present inference fail. A response may justify retaining the conclusion, qualify it, obtain another observation or revise it. Agreement is not the goal when the evidence remains insufficient.
Provide a qualified subject check for errors the participants cannot be expected to resolve. Peers can expose a conflict without being competent to settle it. A facilitator can ensure turns occur without supplying the missing domain judgement; HCD.7/.8 must make that contribution available where required.
Give the recipient an opportunity to use feedback. “Incorrect” or a score may signal trouble while leaving the repair unknown. Feedback can identify the unsupported inference, show the relevant contrast or ask for a justified next observation, followed by a correction and targeted retry. Keep the first attempt and actual help distinguishable.
Protect the intended learning work when AI or a strong peer can complete the product faster. They can model, challenge or check, but the target learner still performs the operation being developed. If the encompassing purpose changes to rapid delivery of a work product, that division of labour can legitimately change; return the changed purpose rather than preserving an unnecessary teaching ritual.
HCD.23 develops mutual explanation and the personal return; HCD.24 develops peer judgement and the author’s use of feedback; HCD.25 develops comparison across projects with a breaking condition. Select the contribution the task needs. When participants must recover their shared course of action, HCD.26 supplies observation, process help and inspection of uptake. HCD.27 develops the preparation, material-transfer and re-entry windows connecting separate episodes.
HCD.22:4.7 - Observe the relevant result and return the next need
Select a personal return that exposes the target under appropriate conditions: a revised explanation, an individual decision on changed data, a physical performance, or a contribution in another integrated task. Do not require an extra test when the performed work already supplies the needed bounded observation.
A correction with feedback, an uncued choice on a new case and delayed performance support different interpretations. Use HCD.11–13 for the corresponding human-evidence question. The quality of the common answer, participant activity and material contribution remain separately reportable.
Inspect failures at their actual connection. An unused annotation calls for transfer or task repair; a correct answer from one participant calls for inspection of other actions; inability to understand a term can call for preparation or material repair; a qualified question waiting past its useful window calls for supply repair. HCD.20 reopens the arrangement when the repaired task changes size, access or burden. HCD.28 revises the whole product only as far as its dependencies change.
