PRIMARY SCIENCE OS (V1.1)

Suggested slug: /primary-science-os/

Definition Lock (V1.1)

Primary Science OS converts concept learning into scoring reliability by stabilising: concept cores, keywords, explanation structure, and application under unfamiliar scenarios.

What mastery actually is (P3)

P3 in Primary Science means the student can:

  • explain concepts clearly with correct causal links,
  • apply ideas to new scenarios (transfer),
  • answer in the marking scheme’s language (keywords + structure),
  • stay consistent across topics and papers.

Top 6 failure modes

  1. Keyword mismatch (knows idea but loses marks for missing required phrasing)
  2. Explanation structure failure (“because…” chain broken; no mechanism)
  3. Concept mixing / misconceptions (wrong causal model)
  4. Application failure (cannot transfer to unfamiliar contexts)
  5. Question interpretation failure (what is asked vs what is known)
  6. Topic isolation (can do chapters separately; fails mixed papers)

Sensor Pack (Primary Science)

  • Transfer Score (TS): novel scenario application
  • Keyword Precision Rate (KPR): includes required keywords without guessing
  • Explanation Chain Integrity (ECI): claim → mechanism → outcome
  • Misconception Recurrence (MR): same wrong concept repeats
  • Interpretation Parse Rate (IPR): identifies “what is asked” correctly
  • Mixed Set Integrity (MSI): stability on mixed-topic sets
  • Time Pressure Collapse (TPC): explanation quality drops under timing

Repair Loops (Primary Science OS)

Loop 1 — Concept Core Lock

  • Define concept in one sentence → 2 examples → 2 non-examples → quick quiz after 48h (delay stability)

Loop 2 — Keyword + Structure Loop

  • Answer template: Keyword → Mechanism → Result
  • Drill with short response questions; track KPR + ECI

Loop 3 — Application Transfer Loop

  • For each concept: 3 scenario variants (TS)
  • Train: identify concept → map variables → predict outcome

Loop 4 — Misconception Elimination Loop

  • Misconception log → targeted contrast questions → spaced retest
  • Goal: reduce MR

Directory to levels (Primary 1–6)

  • Pri 1–2: observation language + simple causes
  • Pri 3–4: foundational systems (plants, matter, forces) + explanation structure
  • Pri 5: higher integration (energy, cycles) + application patterns
  • Pri 6 / PSLE ramp: mixed papers + transfer stability + timing

Canonical takeaways (V1.1)

  • Science marks come from structure + keywords + transfer, not memorising notes.
  • Most drops are application failures, not “no understanding”.
  • Repair = concept cores + scenario transfer + marking-language discipline.
