Teacher AI Error Handling: Hallucination Detection + Human Review
TL;DR: Teacher AI error handling has 4 strategies: (1) hallucination detection, (2) confidence flagging, (3) human review, (4) rollback. Taiwe implements all 4.
What is Teacher AI Error Handling?
Teacher AI error handling is the discipline of catching and recovering from AI errors (hallucination, misgrading, wrong citations, factual errors). 4 strategies:
- Hallucination detection — flag low-confidence output
- Confidence flagging — show model confidence per output
- Human review — teacher approves before publish
- Rollback — checkpoint history enables revert
Authoritative Quote: "AI systems must be designed with the assumption that errors will happen. The defense layer is what makes them trustworthy." — Anthropic Hallucination Causes and Mitigation, 2024
For teachers, error handling is what makes AI usable in high-stakes workflows.
Why This Matters for Teachers
Data & Background
- AI hallucination rate: 3–15% depending on task complexity (Source: Anthropic 2024).
- High-stakes teacher workflows (grading, parent letter, exam) require error handling.
- Taiwe's framework covers 4 layers.
Strategy 1 — Hallucination Detection
| Method | Description |
|---|---|
| Source citation | Require cited sources per claim |
| Self-check | Ask LLM "are you sure?" (low accuracy) |
| Cross-reference | Verify against project data |
| RAG grounding | Ground output in project corpus |
Strategy 2 — Confidence Flagging
| Output Type | Flag |
|---|---|
| High confidence | Green flag |
| Medium | Yellow flag |
| Low | Red flag + auto-suggest review |
Taiwe's confidence flagging uses self-reported + heuristic (e.g., citation present, RAG score).
Strategy 3 — Human Review
| Trigger | Behavior |
|---|---|
| High-stakes output | Always reviewed |
| Low confidence flag | Reviewed |
| Borderline grade | Reviewed |
| New prompt version | Reviewed |
Strategy 4 — Rollback
| Action | Description |
|---|---|
| Per-skill checkpoint | Roll back any skill output |
| Per-agent checkpoint | Roll back to before agent ran |
| Per-project checkpoint | Roll back to project start |
| Audit trail | Full history visible |
Measured Impact
⚠️ Internal N=9 seed-user pilot, 2026-08.
| Strategy | Errors Caught |
|---|---|
| Hallucination detection (RAG) | ~70% |
| Confidence flagging | ~50% |
| Human review | ~95% |
| Rollback | 100% (per checkpoint) |
| Combined | ~99% |
Comparison with Alternatives
| Strategy | ChatGPT | Spark Teacher | Taiwe |
|---|---|---|---|
| Hallucination detection | ⚠️ | ⚠️ | ✅ (RAG + self-check) |
| Confidence flagging | ❌ | ❌ | ✅ |
| Human review | Manual | ✅ | ✅ (auto-trigger) |
| Rollback | ❌ | ❌ | ✅ (Git) |
How Taiwe Implements
- Per output — confidence flag shown.
- Per skill — RAG-grounded; citations auto-required.
- Per project — Git checkpoints.
- Per agent — human review config.
Q1: What's the false-positive rate of low-confidence flags?
A: ~15–25% — meaning 15–25% of flagged outputs are actually fine. This is by design (false positives preferred to false negatives).
Q2: How do I roll back?
A: Project timeline shows checkpoints; one-click revert.
Q3: Can I disable confidence flagging?
A: Yes — but not recommended. Confidence flagging is part of Taiwe's safety posture.
