Why this lesson matters · เหตุผลที่เรียนบทนี้

For learners: Integrate marked word order with C2 sentence hierarchy, agency, parallelism and punctuation so formal recommendations remain precise and easy to process.

For teachers: Meaning-first six-stage route: six architecture diagnoses, five controlled builds, five hierarchy or parallelism repairs, four punctuation decisions, recommendation planning, a 75–90 word paragraph and one focused retry.

สำหรับผู้เรียน: บูรณาการ marked word order กับ hierarchy ของประโยค agency parallelism และ punctuation ระดับ C2 เพื่อให้งานเขียนเสนอแนะเป็นทางการ แม่นยำ และอ่านเข้าใจง่าย

Your Goal

By the end of this lesson, you can diagnose six formal sentence architectures, repair five hierarchy or parallelism failures, choose four punctuation relationships, and produce a precise recommendation paragraph.

คำอธิบายภาษาไทย

Why this lesson matters

Formal writing is not automatically clear because it is long or noun-heavy. Readers need to recover the main claim, actor, evidence, condition and recommendation without rereading. Sentence architecture makes those relationships visible.

PROGRESS FOCUS What improves today?
MEAN · MeaningMap the main claim and the exact relationship of each supporting proposition.
FORM · FormControl clause hierarchy, agency, parallel structure and punctuation without creating ambiguous attachment.

Teacher Lesson Plan

Ask learners to draw the proposition map before editing the sentence. Reward clarity of relationships, not length or nominal density.

Stage 1 · Diagnose six formal sentence architectures

Find the matrix claim first, then map what every other unit does.

STUDENT TASK

Single matrix claimone accountable propositionWho states or does what?
Coordinationtwo equal claimsCould either claim stand alone?
Finite subordinationreason, condition or concessionWhich claim governs the other?
Non-finite clausecompressed supportIs its understood actor secure?
Reporting structuresource and propositionWho is responsible for the claim?
Integrated seriesparallel reasons or actionsDo all items share one grammar frame?
  1. Underline the matrix verb in six examples.
  2. Box the responsible actor or source.
  3. Label every supporting unit: reason, condition, concession, evidence or result.
  4. Explain where a reader could attach the wrong unit.
Finish evidenceSix architecture maps with matrix claim, actor and relationship labels.
Teacher Help · Stage 1

If learners start with punctuation, pause them. First recover the propositions and their hierarchy; only then decide where sentence boundaries belong.

Stage 2 · Build controlled hierarchy and agency

Choose a main clause that carries the recommendation and subordinate only genuine support.

STUDENT TASK
Message setWeak packagingControlled architecture
finding + evidenceThere was a review of the delay and it was found…The review found that the delay resulted from…

source + limitIt is believed that costs may…The finance team estimates that costs may…
two reasonsThe proposal reduces cost and improving access.The proposal reduces cost and improves access.
  1. Build five sentences from proposition cards.
  2. Put the recommendation or finding in the matrix clause.
  3. Name the actor where responsibility matters.
  4. Choose finite or non-finite support only when its attachment is secure.
  5. Read each sentence aloud and state the relationship before the form.
Check the architecture rule

Use an impersonal structure only when the source is genuinely general or already recoverable. If responsibility affects the decision, name the source or actor.

Finish evidenceFive controlled builds with visible claim, hierarchy and agency.
Teacher Help · Stage 2

Ask “What must the reader remember after one pass?” Put that proposition in the matrix clause and demote only supporting information.

Stage 3 · Repair five hierarchy or parallelism failures

Fix the processing problem without removing necessary qualification.

  1. Diagnose all five failures before rewriting.
  2. Repair actor, hierarchy, attachment or parallel form.
  3. Keep every necessary limitation.
  4. Compare the repair with a shorter two-sentence option.
Check what “formal” means

Choose the version that preserves precision with the lowest processing cost. Two controlled sentences can be more formal than one overloaded sentence.

Finish evidenceFive justified repairs that preserve meaning and improve processing.
Teacher Help · Stage 3

Accept more than one repair when the learner can explain its hierarchy, actor and reader effect. Reject cosmetic edits that leave the relationship unclear.

Stage 4 · Choose punctuation for four relationships

Treat punctuation as a relationship decision, not a pause copied from speech.

5 minutes
STUDENT TASK
Australian English · Olivia

Overloaded recommendation

Recover the hidden actor, main claim and competing relationships.

British English · Amy

Controlled recommendation

Map the two equal claims, explanation and limited extra information.

Relationship decisionBest boundaryTest
two independent but closely linked claimssemicolon or full stopCan both sides stand alone?
claim followed by explanation or listcolonDoes the second unit fulfil the first?
essential integrated informationno paired commasWould removal change identification or scope?
supplementary non-integrated informationpaired commas or bracketsCan the sentence survive its removal?
  1. Listen once and recover the recommendation.
  2. Listen again and draw proposition boundaries.
  3. Make four punctuation decisions and name each relationship.
  4. Compare a full-stop alternative for any overloaded sentence.
  5. Retell the recommendation with clearer sentence architecture.
Finish evidenceFour punctuation decisions justified by proposition relationships.
Teacher Help · Stage 4

Do not score accent imitation. Use the two accents to test meaning transfer; audio never starts automatically. Ask for a relationship label before accepting a punctuation mark.

Stage 5 · Plan a precise recommendation paragraph

Give every sentence one primary job and make the evidence-to-action path visible.

  1. Choose a real workplace, study or community decision.
  2. Plan notes only: finding, source, evidence 1, evidence 2, limitation, actor, action and timing.
  3. Use three or four sentences, not one maximal sentence.
  4. Mark the matrix clause in each sentence.
  5. Partner predicts the recommendation before you draft.
Finish evidenceOne paragraph map with visible claim, support, limit and action.
Teacher Help · Stage 5

Ask the partner to paraphrase who should do what and why. If they cannot, revise the proposition map before drafting the paragraph.

Stage 6 · Final Practice: write, verify and retry

Make complex relationships precise enough to survive a cold read.

6 minutes
STUDENT TASK
FINAL PRACTICE

Finding → evidence → limitation → recommendation → cold read → focused retry

  1. Write a 75–90 word formal recommendation paragraph.
  2. Use one controlled subordinate clause and one parallel pair.
  3. Name the responsible actor and recommended action.
  4. Use punctuation to express at least two relationships.
  5. A partner reads once and states the main claim, actor, reason and limitation.
  6. Receive one target—meaning, form or real use—and revise only the weakest sentence.
  7. Read the final paragraph aloud and confirm the relationships are unchanged.
Performance rule: Density is successful only when the reader recovers the architecture on the first pass.

Score the first independent performance

MEAN · MeaningSix diagnoses and the paragraph preserve a recoverable main claim, evidence, limitation and recommendation.
FORM · FormFive repairs control hierarchy, attachment, agency and parallelism; four punctuation decisions match real relationships.
USE · Real useThe 75–90 word paragraph is formal, accountable and understandable after one cold read.
0 · Not yetThe reader cannot recover the main claim, actor or relationship map reliably.
1 · With supportThe paragraph works after one prompt to restore hierarchy, agency, parallel form or a sentence boundary.
2 · IndependentThe paragraph remains precise, accountable and easy to process through the cold read and focused retry.

Result: 0–2 Rebuild · 3–4 Developing · 5–6 C2 performance evidence.

Finish evidenceSix architecture diagnoses + five justified repairs + four punctuation decisions + one precise recommendation paragraph + one focused retry.
Teacher Help · Stage 6

Score the first independent draft across MEAN, FORM and USE. Give one target only, then record whether the revision improves architecture without changing the intended decision.

Grammar you can use
