GOAL: VOCAB.P1
= reliable retrieval + correct meaning + usable sentence output under Primary 1 load.
FAIL CONDITION:
If the method produces recognition only (S0) instead of retrieval + usage (S1/S2/S3),
then the method “does not work”.

ROOT CAUSE:
Most Primary 1 vocabulary methods build a LIST MEMORY.
Primary 1 performance needs a RELIABILITY SYSTEM (retrieval + usage under load).

METHOD:
- copy 10–50 words/day
OUTPUT:
- neat writing
- fast completion
ACTUAL RESULT:
- S0 (recognition) may improve
- S1 (retrieval) remains weak
WHY:
- copying trains motor memory, not recall usage
SYMPTOMS:
- child can “see and know”
- cannot produce in speaking/writing

METHOD:
- read list repeatedly
- highlight “important” words
ACTUAL RESULT:
- familiarity increases
- retrieval does not
WHY:
- repeated exposure ≠ retrieval practice
SYMPTOMS:
- child says “I know this” but blanks during tests

METHOD:
- show card → child says meaning or points to picture
ACTUAL RESULT:
- S0 improves
- S2/S3 do not
WHY:
- no sentence production, no transfer
SYMPTOMS:
- knows meaning, cannot use naturally

METHOD:
- dictionary definition drills
ACTUAL RESULT:
- meaning becomes abstract
- usage remains missing
WHY:
- Primary 1 needs child-safe meaning + example + not-example
SYMPTOMS:
- wrong meanings appear in writing
- confusion in comprehension

METHOD:
- spelling tests before meaning/usage
ACTUAL RESULT:
- spelling may improve
- speaking/writing quality does not
WHY:
- spelling is a stability layer, not the core memory layer
SYMPTOMS:
- child can spell but cannot deploy word in a sentence

METHOD:
- chase “Top 100” fast
- 20–40 new words/week without consolidation
ACTUAL RESULT:
- short-term gains, medium-term collapse
WHY:
- install rate > repair rate
SYMPTOMS:
- forgets most words after 2–3 weeks
- confidence drop

METHOD:
- teach word alone (“word of the day”)
ACTUAL RESULT:
- isolated nodes
WHY:
- without collocations, the word is not “sentence-ready”
SYMPTOMS:
- child avoids advanced words in writing
- repeats basic words (good, nice, happy)

METHOD:
- words taught in random order
- no grouping by topic/function
ACTUAL RESULT:
- weak recall, high forgetting
WHY:
- brain retrieves via networks; random lists form weak edges
SYMPTOMS:
- slow recall
- mixing meanings

METHOD:
- “Write 5 sentences using these words”
- no scaffold
ACTUAL RESULT:
- sentence collapse
WHY:
- Primary 1 load too high without fixed frames
SYMPTOMS:
- broken sentences
- child refuses writing

METHOD:
- word used only in one example sentence
ACTUAL RESULT:
- context-bound memory
WHY:
- child learns the example, not the word
SYMPTOMS:
- cannot use word in new situation
- “I only know it in that sentence”

METHOD:
- weekly test lists
- mark wrong, move on
ACTUAL RESULT:
- errors repeat
WHY:
- no repair loop = no improvement
SYMPTOMS:
- same 20 words always wrong

METHOD:
- “Just read more books”
ACTUAL RESULT:
- comprehension may improve slowly
- active vocabulary stays limited
WHY:
- input without output does not force retrieval
SYMPTOMS:
- can understand more than can say/write

DW methods → S0-only vocabulary
↓
weak retrieval (S1), weak sentence usage (S2)
↓
writing load collapse (S3)
↓
composition becomes repetitive + vague
↓
confidence drop + avoidance

S0: recognition
S1: retrieval
S2: oral sentence usage
S3: written sentence usage

INSTALL_UNIT(word):
- Z0: word + child-safe meaning
- Z1: 2 phrases (collocations)
- Z2: 1 sentence using a stable frame
VERIFY:
- pass S1 + S2 (minimum)

FENCE LOOP:
INPUT → BIND → OUTPUT → FEEDBACK → REPAIR
DAILY:
- 5 words
- 2 phrases each
- speak 2 sentences total
- write 1 sentence total
- repair 1 weak word
RULE:
Do not add new words until yesterday’s weakest words pass S1+S2.

Primary 1 vocabulary does not work when it trains familiarity (S0) instead of retrieval + usage (S1/S2/S3).
Lists, copying, and passive exposure create “ghost vocabulary” that collapses in writing and comprehension tasks.

VOCAB.P1 works when:
- S1 retrieval is stable
- S2 sentence usage is stable
- S3 writing load is emerging
If method produces S0 only (recognition), the system will collapse under load.

TEST KIT:
Pick 5 words the child “learned”.
S1 Retrieval Test:
- Ask: “What is this word?” (no showing the list)
PASS if child says the word correctly within 3 seconds.
S2 Usage Test:
- Ask: “Say one sentence with it.”
PASS if sentence is correct and natural.
S3 Writing Test:
- Ask: “Write one sentence with it.”
PASS if word is spelled correctly AND sentence is complete.

SYMPTOM:
- child says “I know!” only when seeing the list
- blanks when asked to say the word
DIAGNOSIS:
- DW1/DW2/DW3 (Recognition Trap)
- FAILURE MODE: C1 Ghost Vocabulary (S0-only)
REPAIR (3 min):
R1 Retrieval Snap:
- picture/object cue → say word ×2
- repeat for 3 weak words only
RULE:
Stop early. Do not drill 20 words.

SYMPTOM:
- wrong meaning
- uses the word in the wrong place
DIAGNOSIS:
- DW4 (Definition Memorising) or random learning
- FAILURE MODE: C2 Meaning Drift
REPAIR (5 min):
R2 Meaning Rebind:
- child definition ≤ 7 words
- 1 example + 1 not-example
- then 1 simple sentence

SYMPTOM:
- can say the word alone
- sentence becomes awkward or blank
DIAGNOSIS:
- DW7 (Z0-only learning)
- FAILURE MODE: C3 No Bridge (missing Z1/Z2)
REPAIR (6 min):
R3 Phrase Bridge + R4 Frame Clamp:
- add 2 phrases
- use 1 fixed frame:
  “The ___ is ___.” OR “I can ___.”
- child says 2 sentences total

SYMPTOM:
- can say sentence orally
- cannot write it (spelling/punctuation kills recall)
DIAGNOSIS:
- DW5 or no writing transfer training
- FAILURE MODE: C5 Writing Load Collapse (S3 fail)
REPAIR (6–8 min):
R5 Writing Load Step:
- write 1 sentence only
- parent provides the sentence frame
- child writes slowly
- rewrite the weakest sentence once
RULE:
Do not force paragraphs yet.

SYMPTOM:
- writing uses: good, nice, happy, big
- avoids advanced words
DIAGNOSIS:
- C3 No Bridge + lack of scene training
- also often C6 Over-speed collapse earlier
REPAIR (8 min):
R3 Phrase Bridge + Z3 Micro-Scene Mini:
- choose 6 target words
- give 1 short scene prompt
- child says 6 sentences (oral)
- next day write 4 sentences

SYMPTOM:
- high week 1–2
- collapse week 3–4
DIAGNOSIS:
- DW6 Over-speed (install rate > repair rate)
- FAILURE MODE: C6 Rate Overload
REPAIR (3 min + rule change):
R6 Rate Control:
- freeze new words for 1 week
- repair only
- target: S1+S2 stability
NEW RULE:
New words/week ≤ repaired words/week

SYMPTOM:
- tantrum/avoidance
- says “too hard” quickly
DIAGNOSIS:
- overload + repeated failure = confidence collapse
- likely C5 + C6 combined
REPAIR (4–6 min):
R7 Tiny Wins Protocol:
- 3 words only
- oral only (no writing)
- 2 phrases + 1 sentence each
- stop while child is still winning
RULE:
End on success. Confidence is part of the system.

SYMPTOM:
- can decode words
- misunderstands questions/stories
DIAGNOSIS:
- C2 Meaning Drift + low usable vocabulary
- vocabulary is limiting comprehension
REPAIR (8 min):
R8 Meaning + Context Pack:
- pick 3 words from the story
- do R2 meaning rebind
- child says 1 sentence per word
- re-read the same 4 lines

10 sec per word:
cue → say word ×2 → stop

definition (≤7 words)
+ example
+ not-example
+ 1 sentence

add 2 phrases:
- common phrase
- different context phrase

only 3 frames for 2 weeks:
- The ___ is ___.
- I can ___.
- I feel ___ because ___.

write 1 sentence only
check: capital + full stop
rewrite weakest sentence once

new words paused 7 days
