Terminal Nodes Analysis¶
Terminal nodes are concepts that nothing else depends on but have prerequisites. They represent natural endpoints of learning paths — culminating or specialized concepts.
- Total Terminal Nodes: 36 (26.5% of all concepts)
- Healthy Range: 5-40% of total concepts
Concepts at the end of learning paths:
- 7: Hydration Sugar And Caffeine Evidence
- 8: Meal And Snack Evaluation
- 11: Community Nutrition Initiatives
- 20: Youth-Friendly Provider Expectations
- 26: Community-Based Sexual Health Programs
- 28: Preventing Pregnancy And STIs Through Boundaries
- 29: Mutual Respect In Health Decisions
- 36: Maintaining Boundaries While Helping Others
- 40: Indigenous Restorative Justice Approaches
- 42: Cultural Teachings For Wellbeing
- 44: Addressing Exclusion And Bullying
- 45: Addressing Stereotyping And Discrimination
- 47: Mental Health Awareness Campaigns
- 50: Supporting An Elder With Cognitive Impairment
- 51: Sleep And Rest Influences On Health
- 54: Safe Physical Activity Participation
- 57: AED Use
- 59: Chronic Disease Prevention Strategies
- 60: Infectious Disease Prevention Strategies
- 64: Online Emergency Response
...and 16 more
Orphaned Nodes Analysis¶
Orphaned nodes are completely disconnected concepts with no inbound AND no outbound edges. These indicate a quality problem — every concept should connect to the graph.
- Total Orphaned Nodes: 0
✅ No orphaned nodes detected. All concepts are connected to the graph.
Connected Components¶
- Number of Connected Components: 1
✅ All concepts are connected in a single graph.
Indegree Analysis¶
Top 10 concepts that are prerequisites for the most other concepts:
| Rank | Concept ID | Concept Label | Indegree |
|---|---|---|---|
| 1 | 1 | Health | 8 |
| 2 | 13 | Healthy Relationship Characteristics | 6 |
| 3 | 52 | Health Disparities From Social Conditions | 5 |
| 4 | 72 | Substance Use Effects On Physiology | 5 |
| 5 | 17 | Trusted Adult Guidance | 4 |
| 6 | 27 | Personal Boundary Communication | 4 |
| 7 | 71 | Substance Use Effects On Mental Health And Brain Function | 4 |
| 8 | 10 | Food Systems And Chronic Disease Risk | 3 |
| 9 | 18 | Culturally Safe Healthcare Providers | 3 |
| 10 | 21 | Stereotypes And Bias Effects On Relationships | 3 |
Outdegree Distribution¶
| Dependencies | Number of Concepts |
|---|---|
| 0 | 1 |
| 1 | 100 |
| 2 | 35 |
Recommendations¶
- ✅ Terminal node percentage (26.5%): Within healthy range (5-40%)
- ✅ DAG structure verified: Graph supports valid learning progressions
- ℹ️ Consider adding cross-dependencies: More connections could create richer learning pathways
