Bloom's Taxonomy Distribution¶
| Cognitive Level | Target % | Estimated Actual | Count (est.) | Status |
|---|---|---|---|---|
| Remember (define, list, recall) | 10% | 9% | 8 | ✓ |
| Understand (explain, describe, summarize) | 25% | 33% | 29 | ✓ |
| Apply (use, demonstrate, solve) | 25% | 22% | 20 | ✓ |
| Analyze (compare, distinguish, examine) | 20% | 22% | 20 | ✓ |
| Evaluate (judge, critique, assess) | 12% | 10% | 9 | ✓ |
| Create (design, build, formulate) | 8% | 3% | 3 | ✗ (under) |
Note: The "Create" level is underrepresented. Only three Advanced Topic questions explicitly ask students to design something (hurdle system, local food system, protein sustainability evaluation). Adding 3–5 more "Create"-level questions across baking, fermentation, and preservation chapters would bring this into balance.
Answer Quality Analysis¶
Example Usage¶
- Questions with at least one concrete, named example: 73 / 89 (82%)
- Examples use real foods (steak, bread, yogurt, honey, apples, mayonnaise, etc.): ✓
- Examples are appropriate for 9th-grade experience level: ✓
- Questions missing examples (primarily Getting Started and abstract process questions): ~16
Cross-Reference Links¶
- Questions with at least one chapter link: 89 / 89 (100%)
- Links follow consistent relative path format (
chapters/XX-slug/index.md): ✓ - Glossary link mentioned in Getting Started: ✓
- Learning graph link mentioned in Getting Started: ✓
- MicroSims explained and linked in Getting Started: ✓ (described, not deep-linked)
Answer Length Distribution (estimated)¶
| Range | Count | % |
|---|---|---|
| Short (< 100 words) | 3 | 3% |
| Medium (100–175 words) | 31 | 35% |
| Standard (176–225 words) | 38 | 43% |
| Long (226–300 words) | 14 | 16% |
| Very long (> 300 words) | 3 | 3% |
The distribution is appropriate. Getting Started answers are shorter (orientation content), while Advanced Topic answers are longer (more nuanced). No answer appears padded or overly brief for its category.
Reading Level¶
- Vocabulary is appropriately introduced with bold on first use: ✓
- Technical terms are immediately defined in context: ✓
- Sentence complexity is appropriate for 9th grade: ✓
- Scientific notation and units are used consistently (°F with °C, grams, pH): ✓
Organization Quality Checklist¶
| Criterion | Status | Notes |
|---|---|---|
| Logical category progression | ✓ | Getting Started → Core → Technical → Challenges → Best Practices → Advanced |
| Categories are mutually exclusive | Mostly ✓ | Minor overlap between Core and Technical; acceptable |
| Questions are conversational/student-voice | ✓ | "Why does my bread…", "What is…", "How do I…" |
| Bold terms on first use | ✓ | Consistent throughout |
| No duplicate questions | ✓ | No redundancy found |
| Consistent formatting across categories | ✓ | H3 for questions, body text for answers |
| Internal navigation (links between FAQ and chapters) | ✓ | Every answer links to a chapter |
| Links to glossary | Partial | Referenced in Getting Started; not linked per-term in body |
| Questions cover all 15 chapters | Partial | See coverage gaps report |
Chapter Coverage Summary¶
| Chapter | FAQ Questions Referencing It | Coverage |
|---|---|---|
| 01 — Science in the Kitchen | 3 | Adequate |
| 02 — Molecules of Food | 4 | Adequate |
| 03 — Heat and Cooking Science | 9 | Strong |
| 04 — Food Microbiology | 5 | Adequate |
| 05 — Baking Science | 7 | Strong |
| 06 — Sourdough and Wild Fermentation | 6 | Strong |
| 07 — Food Safety and Sanitation | 9 | Strong |
| 08 — Nutrition Science | 5 | Adequate |
| 09 — Food Preservation | 9 | Strong |
| 10 — Sensory Science | 5 | Adequate |
| 11 — Food Technology and Processing | 4 | Light |
| 12 — Agricultural Systems | 3 | Light |
| 13 — Farm to Table / Local Food | 8 | Strong |
| 14 — Global Food Culture | 0 | Missing |
| 15 — Food Engineering and Innovation | 5 | Adequate |
Key gap: Chapter 14 (Global Food Culture) has zero FAQ representation. This chapter covers spice trade history, indigenous food systems, food taboos, Mediterranean diet, food globalization, and climate change — all engaging topics for 9th graders that deserve at least 3–4 questions.
Overall Quality Score¶
87 / 100
| Dimension | Score | Notes |
|---|---|---|
| Answer accuracy and depth | 23 / 25 | Scientifically accurate; minor gap in Create-level depth |
| Example quality and relevance | 22 / 25 | Strong; a few answers in Getting Started lack examples |
| Organization and navigation | 18 / 20 | Excellent; Chapter 14 gap lowers score slightly |
| Reading level appropriateness | 14 / 15 | Well-calibrated for 9th grade throughout |
| Concept coverage breadth | 10 / 15 | ~55% coverage; significant gaps in molecular biology and agri-systems |
Recommendations¶
High Priority¶
-
Add 4–6 questions for Chapter 14 (Global Food Culture) — the only chapter with zero FAQ coverage. Suggested topics: traditional fermented foods by region, the spice trade and food history, food taboos and religion, climate change and food supply, indigenous food systems.
-
Add 3–5 Create-level questions — design challenges like "Design an experiment to test…", "How would you create a fermentation recipe for…", or "What would you include in a school lunch program if you were a food scientist?" to bring Bloom's Create level from 3% to the 8% target.
-
Increase concept coverage from ~55% to ~70%+ — approximately 108 concepts from the learning graph are not addressed in any FAQ answer. See faq-coverage-gaps.md for the prioritized list. Focus first on Critical-gap concepts with many learning graph dependencies.
Medium Priority¶
-
Add per-term glossary links — the glossary is mentioned globally but individual bolded terms in answers could link directly to
glossary.md#termfor students who want a quick definition without leaving the FAQ. -
Add 2–3 questions for Chapter 11 (Food Technology and Processing) — currently only 4 questions cover this chapter, and important concepts like food additives, preservatives, food colorants, and food fortification are not addressed.
-
Add 2–3 questions for Chapter 12 (Agricultural Systems) — soil health, crop rotation, integrated pest management, pollinator health, and composting are well-developed in the learning graph but barely appear in the FAQ.
-
Add a MicroSim-specific FAQ question per unit — currently only one Getting Started question describes MicroSims. A question like "What does the bacterial growth curve MicroSim show?" for each major unit would help students use MicroSims more intentionally.
Low Priority¶
-
Consider adding a "Lab Skills" category — questions about specific lab procedures (measuring pH, calibrating a food thermometer, setting up a controlled experiment) appear embedded in other categories and might be easier to find in a dedicated section.
-
Add 1–2 questions on food careers — the concept "Food Science Career Paths" is in the learning graph but never appears in the FAQ. A question connecting the science to career options would increase motivation, especially for 9th graders thinking about high school course choices.
-
Review Getting Started answer lengths — three answers in this category are under 100 words. While brevity is appropriate for orientation content, a few (particularly "Is any cooking experience required?") could briefly introduce a concept that anchors the question to the course's scientific approach.
