Vocabulary OS – Operator Manual (PSLE)

Three primary students in matching blue pinafores work together over open books at a classroom table, with colourful stationery and lesson notes on a whiteboard.

(Parents / Tutors / Child) — Almost-Code + V1.1 inserts)

This is the “how to run it” page.
It turns Vocabulary OS from “content” into a repeatable control system.

I. Definition Lock

Operator (Vocabulary OS)

An operator is the person running the loop: selecting words, scheduling repetitions, forcing deployment, measuring drift, and routing repairs.

Goal

Build retrieval-stable vocabulary that survives PSLE composition load (time pressure + narrative complexity).

Gold Rule

If a word cannot be deployed naturally in a scene, it is not owned.

II. Roles (3 Operators)

A) Parent Operator (Low time, high leverage)

  • maintains weekly rhythm
  • checks output for “forced insertion”
  • logs drift signals

B) Tutor Operator (Precision repair)

  • identifies failure mode
  • prescribes drills
  • calibrates tone and collocation

C) Child Operator (Ownership)

  • builds phrase bank
  • does retrieval reps
  • produces timed writing outputs

III. System Diagram (Closed Loop)

INPUT (words)
  ↓
ENCODE (meaning + collocation + tone)
  ↓
RETRIEVE (speed + accuracy)
  ↓
DEPLOY (scene writing)
  ↓
FEEDBACK (mark drift)
  ↓
REPAIR (targeted drill)
  ↓
RETEST (same scene type)
  ↺

Vocabulary doesn’t grow by “adding words”.
It grows by closing loops.

IV. The 5 FENCE Rules (Non-Negotiable)

Rule 1 — Small Set, High Density

  • 8–12 words per week (PSLE)
  • never exceed 15

Rule 2 — Collocation before Synonyms

  • 3 natural pairings per word
  • synonyms only after Z1 is stable

Rule 3 — Scene Forces Truth

  • every week must include a scene deployment
  • if it sounds fake, the word is not owned

Rule 4 — Timed Output is the real test

  • untimed writing lies
  • timed writing reveals collapse

Rule 5 — Repair is normal

  • errors are not shame
  • errors are routing signals

V. Weekly Execution Protocol (Copy-Paste Schedule)

Mon: Word Intake (10–15 min)

  • pick 10 words (from PSLE Pack)
  • child writes:
  • meaning in own words
  • 1 sentence each

Operator checks:

  • meaning correct?
  • sentence natural?

Tue: Phrase Encoding (10–15 min)

For each word:

  • 3 collocations
  • 1 misuse trap

Example format:

reluctant:
  + reluctant to admit / reluctant to apologise / reluctant to speak
  - reluctant weather (wrong domain)

Wed: Retrieval Drill (8–12 min)

  • parent/tutor asks:
  • “Use _ in a sentence about _.”
  • “Give 2 collocations.”
  • “What’s the wrong way people use it?”

Goal:

  • speed + stability

Thu: Micro-Scene (15–20 min)

  • 120–160 words
  • must naturally use 6+ target words

Operator checks:

  • forced insertion?
  • tone mismatch?

Sat: Timed Composition (45–60 min)

  • must use 8–10 target words
  • words must be distributed (not dumped)

Sun: Drift Review (10 min)

Score each word using the sensor panel below.

VI. Sensor Panel (The Operator’s Dashboard)

Score each word 0–2:

M (Meaning)

  • 0 wrong
  • 1 correct but vague
  • 2 precise and correct

T (Tone)

  • 0 wrong emotional intensity
  • 1 acceptable but off
  • 2 correct and natural

C (Collocation)

  • 0 unnatural pairing
  • 1 okay but weak
  • 2 strong natural pairing

D (Deployment)

  • 0 forced insertion
  • 1 slightly forced
  • 2 natural and smooth

Total per word = /8

Routing:

  • 0–4 = repeat next week (repair)
  • 5–6 = partial (keep in rotation)
  • 7–8 = owned (maintenance)

VII. Failure Mode Router (Diagnosis → Fix)

FM1 — Fancy Word Syndrome

Signal:

  • word is “impressive” but unnatural

Fix:

  • ban the word for one week
  • rebuild with collocations + scene role
  • reintroduce only if it fits

FM2 — Synonym Misfire

Signal:

  • swaps “angry/annoyed/furious” randomly

Fix:

  • build a gradient ladder
  • annoyed < irritated < furious < enraged
  • force 4 micro-sentences showing escalation

FM3 — Tone Mismatch

Signal:

  • uses “ecstatic” in a sad scene

Fix:

  • label word tone class (positive/negative/neutral)
  • must pair with matching scene emotion

FM4 — Collocation Error

Signal:

  • “fragrant sound”, “echoing perfume”

Fix:

  • domain lock:
  • scent words only with smell nouns
  • sound words only with sound nouns

FM5 — Retrieval Collapse Under Time

Signal:

  • knows word in practice, forgets in exam

Fix:

  • compress set to 6–8
  • increase timed outputs
  • do “rapid retrieval” drills (30 seconds each)

FM6 — Vocabulary Dumping

Signal:

  • all words appear in one paragraph

Fix:

  • “Distribution rule”
  • 2 words per paragraph minimum
  • outline first, then insert words naturally

VIII. Scene Types (Choose 1 per Week)

Use scene types to stop randomness.

  1. Apology / Integrity
  2. Helping a stranger
  3. Competition pressure
  4. Conflict with friend
  5. Fear / courage
  6. Surprise / discovery
  7. Mistake → repair → growth

Each scene type has predictable vocabulary lanes.

IX. Retest Protocol (The Secret Sauce)

A word is not owned until it passes two retests:

  1. same word, different scene
  2. same scene, different word set

This prevents:

  • “memorised scene”
  • brittle vocabulary

X. Minimal Tools (No fancy stuff)

Child needs only:

  • word bank
  • phrase bank
  • scene bank
  • weekly score sheet

Parent needs only:

  • 10 minutes on Sunday
  • 1 timed session on Saturday

Tutor adds:

  • failure-mode diagnosis
  • precision editing

XI. Benchmarks (12–16 weeks)

Week 1–4

  • stop forced insertion
  • stabilise collocations

Week 5–8

  • natural deployment in micro-scenes
  • fewer tone mismatches

Week 9–12

  • timed writing can deploy 8–10 words reliably

Week 13–16

  • transfer across many prompts
  • vocabulary becomes automatic

XII. “LLM Short Intro” Block (Paste at Top of Article)

How to use an LLM with this Operator Manual
Copy your child’s composition into an LLM and ask it to:

  1. highlight forced vocabulary
  2. detect tone mismatch
  3. list collocation errors
  4. suggest 2 repair drills
  5. produce a retest prompt for next week

The LLM is not the teacher.
It is the diagnostic + repair assistant.

XIII. LLM Instruction (Operator Prompt)

Use this exactly:

You are a PSLE Vocabulary OS Operator Assistant.
Input I will provide:
(A) Target word list (8–12 words)
(B) Child’s micro-scene OR timed composition
(C) Optional: the scene type (apology/help/competition/etc.)
Your job:
1) Score each target word using M/T/C/D (0–2 each).
2) Identify failure modes (FM1–FM6) with evidence.
3) Provide 3 “repair drills” for the 3 worst words.
4) Rewrite ONLY the weakest paragraph to model natural usage.
5) Generate:
   - 1 micro-scene prompt (120–160 words target)
   - 1 timed composition prompt (PSLE style)
   Both must naturally fit 8–10 target words.
Constraints:
- Do not add fancy words.
- Preserve the child’s voice.
- Keep sentences PSLE-appropriate.
Output format:
- Score table
- Failure mode list
- Repair drills
- Weak paragraph rewrite
- Two new prompts
