HCD.18:0.1 - Working Terms
| Term | Meaning in this pattern |
|---|---|
| Instructional material | The explanations, examples, tasks, representations, and usable returns offered to support specified learning work. A worksheet, book, or guided interface may carry this content. |
| Declared use | The audience, tasks, prerequisites, ordinary assistance, and decision for which the evaluation is intended. |
| Task denominator | The work and consequential variations the material promises to support, recovered from that work and its subject requirements rather than counted from the material’s headings. |
| Characteristic | A property whose possible values can change use, repair, evidence collection, or protection of another property. |
| Evaluation specification | The defined object and use, selected characteristics and scales, evidence requirements, result meanings, and conditions under which an evaluator may draw a conclusion. |
| Material value | A qualified judgement about a selected property of the material. The evidence supporting the judgement and the material’s fit to the specification remain separately interpretable. |
These are working terms, not new artifact types. A short written agreement can carry the specification when it supplies the required meaning.
