Bloom's Taxonomy Distribution (Overall)
Targets are the average of each chapter's own target (introductory chapters 1-3, intermediate 4-17, advanced 18-20).
| Level | Actual | Target | Deviation |
|---|---|---|---|
| Remember | 20.0% (40) | 25.8% | -5.8% ✓ |
| Understand | 29.5% (59) | 30.0% | -0.5% ✓ |
| Apply | 29.0% (58) | 27.0% | +2.0% ✓ |
| Analyze | 19.0% (38) | 15.0% | +4.0% ✓ |
| Evaluate | 1.5% (3) | 1.5% | +0.0% ✓ |
| Create | 1.0% (2) | 0.8% | +0.2% ✓ |
Largest deviation is 5.8 percentage points (Remember is under target), inside the ±15% tolerance. Evaluate and Create questions appear only in Chapters 18 to 20, as intended.
Answer Balance (Overall)
- A: 26.0% (52/200)
- B: 25.5% (51/200)
- C: 25.0% (50/200)
- D: 23.5% (47/200)
Every chapter has 2 or 3 correct answers per letter, and no letter repeats more than twice in a row.
Explanation Quality
- Every question has an explanation of 50 to 79 words (average 62); the target is 50 to 100.
- Every explanation names the correct letter, explains why the distractors are wrong where useful, and ends with a Concept Tested label and a See link.
Link Validation
All 200 See links point to index.md in the same chapter folder, and every #anchor was checked against the headings of that chapter's index.md using the MkDocs heading-slug rules. No broken anchors were found. A full mkdocs build into a scratch folder reported no warnings about the quiz pages.
Concept Coverage
Across all chapters, 179 of 350 learning-graph concepts listed in the chapters (51%) are named as the Concept Tested for at least one question. With 10 questions per chapter and 11 to 24 concepts per chapter, the 75% target in the skill is not reachable for most chapters. Questions were weighted toward concepts with high concept impact scores.
Quality Rubric (automated)
| Check | Points | Result |
|---|---|---|
| Format, structure, and links (10 questions, 4 options, one correct answer, valid anchors) | 25 / 25 | All 20 files pass |
| Answer balance (20 to 30% per letter) | 15 / 15 | 23.5% to 26.0% |
| Bloom's distribution (within tolerance of target) | 23 / 25 | Largest deviation 5.8 points |
| Explanation quality (50 to 100 words, concept label, link) | 15 / 15 | All 200 pass |
| Concept coverage (51% of listed concepts vs 75% target) | 14 / 20 | Limited by 10 questions per chapter |
| Total | 92 / 100 |
This rubric checks structure and balance. It cannot judge whether each distractor is plausible or whether each question has a single defensible answer, so the instructor should read the questions before using them for grading.
Recommendations
- Have a teacher read through at least one quiz per unit for ambiguity and reading level; the checks above are mechanical.
- Chapters 2, 3, 6, 8, 14, 15, 16, 18, and 20 cover 20 or more concepts. If broader coverage is wanted, raise those quizzes to 12 questions.
- Re-run this skill after major chapter edits, since the See anchors depend on the chapter headings.
