Unified Almost-Code Measurement Spec (Registry-Clean) v0.2
PAGE-ID: EDK-MET-MTH-GAUGE-PBS-v0.2
Role: LAN.Measurement + Scorecard + DriftAlarm
Purpose: convert “I think I can do it” into measurable stability under variation and time.
0) Definition Lock
Math Gauge := the measurement layer of Math OS that scores a learner on:
- Precision (accuracy + correctness)
- Bandwidth (structure recognition / compression ability)
- Speed (pace stability under time)
- DriftRisk (silent collapse risk under pressure)
Lock: A topic is “learned” only if it survives variation + timed conditions, not just homework form.
1) The Four Core Metrics (LOCKED)
Metric P — Precision Score (0–5)
Meaning: correctness, clean steps, correct method execution.
| Score | Meaning |
|---|---|
| 0 | cannot solve / random |
| 1 | partial but unstable |
| 2 | solves only in one form |
| 3 | usually correct, minor slips |
| 4 | correct across forms |
| 5 | correct + explains + checks reliably |
Feeds from sensors: Foundation Fluency, Error Recurrence.
Metric B — Bandwidth Score (0–5)
Meaning: “how much structure you see” per glance; speed of recognising the type and reducing it.
| Score | Meaning |
|---|---|
| 0 | cannot classify |
| 1 | slow recognition |
| 2 | recognises with hints |
| 3 | recognises independently |
| 4 | fast recognition + clean plan |
| 5 | can compress & generalise patterns |
Feeds from sensors: Method Selection, Transfer/Variation.
Metric S — Speed Score (0–5)
Meaning: pace stability, time-to-solution under exam-like conditions.
| Score | Meaning |
|---|---|
| 0 | cannot finish |
| 1 | severe time collapse |
| 2 | finishes but rushed errors |
| 3 | pace acceptable |
| 4 | fast + stable |
| 5 | reflex-level stable under pressure |
Feeds from sensors: Pace Budget, Fluency.
DriftRisk — {Low, Medium, High}
Meaning: probability of silent failure under load even when the student “can do” untimed.
High DriftRisk indicators:
- careless spike under timing
- method switching / panic
- large variance between practice and test
- end-of-paper collapse
Feeds from sensors: Pace Budget + Error Recurrence + Transfer.
2) Math Gauge Scorecard (Topic-Level)
Each topic family gets a scorecard:
- Precision __ / 5
- Bandwidth __ / 5
- Speed __ / 5
- DriftRisk: Low / Medium / High
- Notes: top 1 failure bucket (B1–B6)
3) Certification Ladder (Optional, mirrors Vocabulary Gauge)
- Bronze: Foundation stable (P≥2 and DriftRisk not High)
- Silver+: Precision ≥ 3
- Gold+: Bandwidth ≥ 3
- Professional+: Speed ≥ 4
- Critical+: passes trap suite (mixed set + timed, low drift)
4) Minimal Test Protocol (How to produce the numbers)
To compute P/B/S without over-testing:
Test Set A — Accuracy (Precision)
- 8–12 questions in one family, include 2 variants (V1/V2)
Test Set B — Recognition (Bandwidth)
- 10 “signal-only” items (choose method without solving)
Test Set C — Timed Mini (Speed)
- 15–25 minutes, mixed set (small paper)
- enforce pace budget + checking protocol
Then compute:
- Precision = accuracy + step quality
- Bandwidth = method recognition speed/accuracy
- Speed = completion + stability under time
- DriftRisk = variance + careless spike rate
5) Reading the Math Gauge — Decision Policy
Unified Almost-Code Interpretation Spec v0.2
PAGE-ID: EDK-STD-MTH-GAUGE-READING-v0.2
5.1 The One Rule
The lowest metric determines the next action.
Case A — Precision low (0–2)
Action: Fluency Lab + Repair Lab
Do not: timed papers yet.
Case B — Bandwidth low (0–2)
Action: Method Signal Lab + Variation Ladder
Do not: memorise steps.
Case C — Speed low (0–2)
Action: Timed Stability Lab with smaller scope
Do not: increase breadth.
Case D — DriftRisk High (any score)
Action: freeze new topics; isolate weak buckets; repair + retest ≤ 7 days.
6) Failure Mode Trace (Gauge-Specific)
Trace ID: EDK-TRACE-MTH-NOMEASURE-v0.2
no measurement→ “can do” illusion→ weak transfer→ timed collapse→ repeated errors
Repair
apply Math Gauge→ read the Gauge→ run the right Lab→ retest
