FAQ Coverage Gaps

Concepts from the learning graph not referenced by any answer in the FAQ. "Centrality" is the number of other concepts in the graph that list this concept as a dependency — a rough measure of how foundational it is.

83 of 226 concepts (36.7%) are not currently tagged in the FAQ. Most are narrow, low-centrality details that are folded into a broader answer's prose without being pulled out as their own question.

Critical Gaps (High Priority)

High-centrality concepts (5+ dependents) without dedicated FAQ coverage:

  1. Variable Creation
  2. Centrality: High (11 dependents)
  3. Category: Core Concepts

  4. Suggested Question: "What is Variable Creation and how do I make my first variable?"

  5. Forever Loop

  6. Centrality: High (8 dependents)
  7. Category: Core Concepts

  8. Suggested Question: "Why is the Forever Loop different from the Repeat Loop?"

  9. Sound Blocks

  10. Centrality: Medium-High (5 dependents)
  11. Category: Technical Details

  12. Suggested Question: "What can I do with the Sound Blocks besides playing a sound?"

  13. Storyboarding

  14. Centrality: Medium-High (5 dependents)
  15. Category: Best Practices
  16. Suggested Question: "How does Storyboarding help me plan a story-based project?"

Medium Priority Gaps

Moderate-centrality concepts (2-4 dependents) without FAQ coverage:

Concept Centrality Suggested Category
Algorithmic Thinking 4 Core Concepts
Plan Phase 4 Best Practices
Random Number 4 Technical Details
Boolean Logic 3 Core Concepts
Costumes Tab 3 Getting Started
Custom Block Definition 3 Best Practices
Imagine Phase 3 Best Practices
List Item Access 3 Technical Details
Project Page 3 Getting Started
Create Phase 2 Best Practices
Enemy Movement 2 Advanced Topics
List Length 2 Technical Details
Pick Random 2 Technical Details
Score Variable 2 Advanced Topics

Low Priority Gaps

Leaf nodes and narrow sub-concepts (0-1 dependents) without FAQ coverage — 65 concepts, mostly individual Pen sub-blocks, individual comparison/Boolean operators, individual backpack/list actions, and single extensions already summarized under a broader question:

Add To List, Asset List, Beat Synchronization, Change Tempo, Clear Graphics, Code Tab, Commenting, Community Feedback, Community Guidelines, Condition Controlled Loop, Conditional Branching, Credit Attribution, Debugging Strategies, Decision Making, Delete From List, Dice Roll, Drag And Drop, Drawing Trails, Equal Operator, Erase All, Error Detection, File Menu, Flowchart, Geometric Patterns, Greater Than Operator, Hide Variable, Infinite Loop Detection, Lip Sync Animation, List Block Category, List Contains, Lives Variable, Loop Termination, Makey Makey Extension, Micro Bit Extension, Motion Detection, My Blocks Category, Negative X, Negative Y, Pair Programming, Paste From Backpack, Pen Color, Pen Down, Pen Size, Pen Up, Physical Computing, Positive X, Positive Y, Project Description, Project Tags, Pseudocode, Rainbow Lines, Remix Tree, Remixing, Scene Planning, Show Variable, Snap Together, Sounds Tab, Step By Step Thinking, Storyboard, Talking Sprites, Timer Variable, Variables Block Category, Zoom Controls.

Recommendations

  1. Add questions for all 4 critical gaps above — each is genuinely foundational (Variable Creation and Forever Loop especially — 11 and 8 dependents respectively — are among the highest-centrality concepts in the entire 226-concept graph).
  2. Consider adding questions for the 14 medium-priority gaps in a future FAQ revision, or fold them as secondary concepts tags into existing answers where they're already mentioned in passing (e.g. "Random Number" and "Pick Random" are closely related and could share one Technical Details answer).
  3. The 65 low-priority gaps can be addressed in a future update; forcing a dedicated question for each would fragment the FAQ without adding much value, since most already appear inside a broader answer's explanatory text.
