HCD.14:4.2.1 - Decide Whether the Model or the Pathway Must Change
A surprising result can change different things. Use the observation and its conditions to identify the affected claim before prescribing another exercise.
| What the observation changes | Appropriate revision |
|---|---|
| Evidence for this person’s current contribution, while the descriptions and relations still fit | Update the current profile and retain the model. Use the new position to choose a needed continuation. |
| A category merges different strategies, a purported prerequisite is bypassed, or an omitted condition explains contradictory positions | Return the local model to HCD.4:4.2.1–4.3.1. Revise the description or relation and identify which pathway assumptions used it. |
| The model remains useful but the selected task, help, provider, time or learning mechanism does not fit | Revise the affected pathway or arrangement through HCD.5–HCD.10 while preserving the supported model claims. |
| The observation itself is defective or cannot distinguish the rival accounts | Repair the assessment through HCD.11 or retain the unresolved relation; do not manufacture a developmental change. |
For a model revision, say what the earlier model predicted, which observation it cannot accommodate adequately, what the replacement distinguishes, and what could challenge the replacement. Reconsider dependent learning opportunities without reopening unrelated contributions. A plausible revised model may support a bounded next trial while its broader developmental claims remain untested.
Keep the actual trajectory intact: the tasks attempted, help received, first responses and later corrections retain their original conditions. Add the new interpretation and subsequent plan. Neither rewriting the model nor revising a curriculum demonstrates that the person acquired or lost capability.
