Concept coverage in chapter content 574 concepts documented across chapters per chapters/index.md (200 core + 374 lab-derived) 15/15

Content completeness was excellent going in — this FAQ was generated from a mature, mostly-complete textbook rather than an early draft.

Bloom's Taxonomy Distribution

Actual vs. category-weighted target (each category's target percentages from the FAQ generator skill, weighted by that category's question count and summed):

Level Actual Target Deviation
Remember 20.9% (19) 21.6% −0.7% ✓
Understand 34.1% (31) 31.1% +3.0% ✓
Apply 22.0% (20) 24.8% −2.8% ✓
Analyze 15.4% (14) 14.5% +0.9% ✓
Evaluate 5.5% (5) 4.6% +0.9% ✓
Create 2.2% (2) 3.3% −1.1% ✓

Total absolute deviation: 9.4 percentage points (0–10% band).

Bloom's Distribution Score: 25/25 — every category individually tracks its target range (Getting Started skews Remember/Understand as intended; Advanced Topics skews Analyze/Evaluate/ Create as intended), and the aggregate deviation is well inside the excellent band.

Concept Coverage

Two coverage figures are reported because this course maintains two overlapping concept inventories: the 200-concept course-planning DAG (concept-dependencies.csv, used for prerequisite sequencing) and the 550-term glossary (glossary.md, the specific vocabulary actually used in chapter prose). Coverage below is computed by exact (hyphen/apostrophe-normalized) substring matching of each concept label against the full FAQ text — a conservative method that undercounts true thematic coverage. For example, "Radix-4 FFT" is flagged as uncovered even though What are radix-4 and split-radix FFTs, and how do they compare to radix-2? discusses it directly, because the FAQ's phrasing ("radix-4 and split-radix FFTs") never places the words "radix-4" and "FFT" immediately adjacent.

Coverage of the 200-concept core learning graph: 24.0% (48/200)

Coverage of the 550-term glossary: 26.7% (147/550)

High-centrality concepts (top 25 by number of downstream dependents) are covered much more completely: 16/25 (64%) — every top-7 concept (Fast Fourier Transform, ARM Cortex M Series, Windowing Functions, Complex Numbers, Discrete Fourier Transform, Cooley-Tukey Algorithm, Time Domain) is directly covered. The nine gaps in the top 25 are umbrella/category-level labels from the planning DAG (e.g. "Performance Metrics," "Statistical Analysis," "Fixed Point Numbers") whose specific sub-concepts are covered under more concrete names (execution time, throughput, mean, standard deviation, Q15, Q31) rather than the umbrella term itself.

Why coverage is lower than a typical FAQ: this course defines an unusually large vocabulary — 550 glossary terms across 27 chapters — for a curated, 91-question FAQ to name-check individually. A FAQ answering common student questions naturally clusters around the ~50-80 concepts students actually ask about, while granular implementation details (e.g. "Cache Line Size," "Structure Packing," specific register names) are better served by the glossary itself, which already exists and is comprehensive. Treat the number below as a starting point for expansion, not a defect to fix all at once.

Coverage Score: 10/30 (below the 50% threshold under the skill's literal scoring rubric)

Recommendations

High Priority

  1. If deeper concept-level coverage is a goal, add a second wave of Technical Detail and Core Concept questions targeting the 12 high-centrality gaps identified in faq-coverage-gaps.md: Performance Metrics, Statistical Analysis, Compiler Optimization Levels, Fixed Point Numbers, Q Format Notation, Input Signal Generation, Sine Wave Representation, DSP Extension Instructions, Memory Alignment, Data Layout, Test Case Design, and Linking Libraries.
  2. Re-run the coverage check after Instructor's Guide content (docs/instructors-guide/, currently untracked/in progress) stabilizes, since it may surface additional student-facing questions worth folding into this FAQ.

Medium Priority

  1. Consider 2–3 more examples in the Best Practice and Advanced Topic categories (currently 33% and 25% respectively) to bring every category above the 40% target individually, even though the aggregate already clears it.
  2. If a future revision adds a "Hardware & Wiring" question or two (e.g., a wiring diagram reference for the OLED/microphone/buttons), link directly to any wiring-diagram assets the course may add later.

Low Priority

  1. The 100-word-per-answer floor is met but tight on a few Getting Started questions; a light pass to add one more concrete detail to the shortest 5–10 answers would improve consistency.
  2. Consider a "Search Keywords" appendix or per-question tag list in a future revision if this FAQ is wired into a site search widget, using the keywords field already present in faq-chatbot-training.json.
