PSLE-OS 12-Week Operator Program

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.

(Full Triad Calendar — English + Science + Math + Vocabulary, with Codes + Retest Cadence)

This is the PSLE equivalent of your OLEVEL 12-week machine — but tuned for Primary load.

Goal by Week 12:

  • English composition + comprehension + editing stable under time (Z3)
  • Vocabulary deployment natural (no dumping) (Z3)
  • Science cause→mechanism→effect stable + data handling (Z3)
  • Math accuracy + modelling stable (Z3)
  • Every repeated error is routed + retested within 7 days

0) Operator Rules (Non-Negotiable)

Rule A — Code every mistake

  • Max 2 lane codes + 1 PSLE overlay code per error.

Rule B — Repair must be short

  • One drill = 10–20 minutes.

Rule C — Retest within 7 days

  • No retest = no learning.

Rule D — Simulation only counts with analysis

  • Paper → error log → routing → retest.

1) Weekly Structure (Fixed for all 12 Weeks)

Day 1 — Vocabulary (VOC)

  • Z1–Z2: tone/collocation + scene deployment

Day 2 — English (Writing)

  • CMP arc + paragraph roles + timed stability

Day 3 — English (Reading + Editing)

  • RDN evidence/inference + EDT speed bursts

Day 4 — Science

  • cause→mechanism→effect + data interpretation

Day 5 — Math

  • accuracy + problem solving/modeling

Day 6 — Retest Day (all codes)

  • retest anything repaired in the last 7 days

Day 7 — Light review / rest

Time per day:

  • 45–75 minutes (parents can compress to 30–45)

2) PSLE Overlay Codes (Used every week)

Use 1 overlay code per error cluster:

  • PSLE-Z2-VAR-TRANSFER (unfamiliar question variation)
  • PSLE-Z3-PAC-BUDGET (time allocation)
  • PSLE-Z1-MSK-STRUCT (answer format)
  • PSLE-Z1-ERR-CLASS (error type classification)
  • PSLE-Z3-SIM-RETEST (retest discipline)

    Evidence → Interpretation → Match demand
  • 2 short comprehension practices + corrections

Benchmark:

  • wrong answers reduce due to evidence anchoring

Week 4 — Editing Speed Stability

Targets:

  • ENG-PRI-Z1-EDT-ERRTYPE
  • ENG-PRI-Z3-EDT-SPEED
    Overlay:
  • PSLE-Z3-PAC-BUDGET

Work:

  • 10-question micro drills × 3
  • 30 sec/item timed bursts

Benchmark:

  • fewer “random guessing” edits

Week 5 — Science Cause→Mechanism→Effect

Targets:

  • SCI-PRI-Z1-CEF-CHAIN
  • SCI-PRI-Z2-CEF-MECH
    Overlay:
  • PSLE-Z1-MSK-KEYWORD (if you’re using the wrapper nodes)

Work:

  • 3-line chain drill × 10 questions
  • mark-scheme keyword targeting

Benchmark:

  • mechanism sentences appear consistently

Week 6 — Science Data Interpretation

Targets:

  • SCI-PRI-Z1-DAT-VAR
  • SCI-PRI-Z2-DAT-EXPLAIN
    Overlay:
  • PSLE-Z2-VAR-REMAP (if used)

Work:

  • variable → measure → trend → explain protocol
  • 10 graph/table drills

Benchmark:

  • less “trend only, no why”

Week 7 — Math Accuracy Compression

Targets:

  • MTH-PRI-Z0-SKILL-OPS
  • MTH-PRI-Z3-TIM-STABLE
    Overlay:
  • PSLE-Z3-PAC-BUDGET

Work:

  • daily 10-min accuracy burst (signs, fractions, copying)
  • enforce check step (estimate / reverse)

Benchmark:

  • careless rate drops

Week 8 — Math Modelling / Word Problems

Targets:

  • MTH-PRI-Z1-MODEL-REL
  • MTH-PRI-Z2-APP-WORD
    Overlay:
  • PSLE-Z2-VAR-TRANSFER

Work:

  • bar model / unit method drills
  • “represent first” protocol

  • ENG-PRI-Z3-CMP-TIMING
  • ENG-PRI-Z3-RDN-PACE
    Overlay:
  • PSLE-Z3-SIM-FULLPAPER (if used)

Work:

  • timed English paper segment set
  • full analysis + repair + retest scheduled

Benchmark:

4) Weekly Retest Rules (Critical)

For every repair:

  • Retest within 7 days
  • Minimum retest size:
  • Vocabulary: 2 micro-scenes + 1 timed paragraph
  • Comprehension: 8–12 questions
  • Editing: 15 items timed
  • Science: 10 OE items (mix)
  • Math: 20 mixed questions (or 10 long)

Code:

  • PSLE-Z3-SIM-RETEST

5) Why This Works (Short)

Because it forces:

  • vocabulary deployment stability
  • composition structure stability
  • comprehension evidence discipline
  • editing speed reliability
  • science mechanism clarity
  • math accuracy + modelling
  • and retest cadence

That’s P3.
