Why this lesson matters · เหตุผลที่เรียนบทนี้

For learners: Control proposition hierarchy, source ownership, attachment and reference in multi-source explanations.

For teachers: Group 9 moves from meaning stability to information focus, noun density and embedded-clause control, then transfers into fine stance; connectors remain a cohesion comparison.

สำหรับผู้เรียน: ควบคุมลำดับชั้นของข้อความ เจ้าของคำกล่าว การเกาะของส่วนขยาย และการอ้างอิงในการอธิบายหลายแหล่งข้อมูล
สำหรับครู: กลุ่ม 9 พัฒนาจากการคงความหมาย ไปสู่จุดเน้น ความหนาแน่นของกลุ่มคำนาม และการควบคุมอนุประโยคซ้อน ก่อนถ่ายโอนไปสู่การวางท่าทีอย่างละเอียด โดยใช้คำเชื่อมเป็นบทเปรียบเทียบ

Your Goal

By the end of this lesson, you can diagram six multi-layer sentences, distinguish five clause functions, repair four attachment or reference problems, and deliver a precise multi-source explanation with controlled embedding.

Why this lesson matters

Embedding lets a speaker show who said what, which claim is qualified and how causes, conditions or evidence relate. When the hierarchy disappears, listeners confuse the main claim with a source’s claim or attach a modifier to the wrong host.

ภาษาไทย: การซ้อนอนุประโยคช่วยบอกว่าใครกล่าวอะไร ข้ออ้างใดมีเงื่อนไข และเหตุผลหรือหลักฐานเชื่อมกันอย่างไร หากลำดับชั้นไม่ชัด ผู้ฟังอาจสับสนระหว่างข้อสรุปหลักกับคำกล่าวของแหล่งข้อมูล หรือจับส่วนขยายเข้ากับส่วนที่ผิด

Teacher Lesson Plan

Start from proposition hierarchy, not punctuation. Learners must identify the main claim, each embedded proposition, its function and its host before they edit sentence length.

StageTeacher moveEvidence to collect
1 · DiagramSeparate matrix and embedded propositions.6 hierarchy diagrams
2 · ClassifyName five clause functions and their hosts.5 function decisions
3 · ControlManage clause depth, host distance and source ownership.6 controlled rewrites
4 · RepairRepair four attachment or reference failures.4 minimal repairs
5 · TransferTrace hierarchy in two accent-varied explanations.2 source maps
6 · PerformScore MEAN/FORM/USE and target one retry.Multi-source explanation + retry

Stage 1 · Diagram six multi-layer sentences

Find the matrix clause first; then place each embedded proposition under the word or clause that hosts it.

4 minutes
STUDENT TASK
MATRIXThe sentence’s main grammatical frame
HOSTThe verb, noun, adjective or clause that licenses detail
EMBEDDEDA proposition functioning inside the larger frame
SentenceMatrix frameEmbedded hierarchy
The report suggests that the delay began after the supplier changed the process.The report suggests XX = delay began [after supplier changed process]
What the panel could not confirm was whether the figures that appeared online were final.X was YX = what panel could not confirm; Y = whether figures [that appeared online] were final
  1. Box the matrix clause in six sentences.
  2. Bracket every embedded proposition.
  3. Draw an arrow from each embedded clause to its host.
  4. Number the depth: 0 matrix, 1 embedded, 2 embedded inside embedded.
  5. Paraphrase the sentence as separate simple propositions.
Finish evidenceSix proposition-hierarchy diagrams.
Teacher Help · Stage 1

A sentence can begin with an embedded subject such as What the panel found. The first words are therefore not automatically the matrix clause. Ask which frame can stand as the sentence’s highest grammatical relationship.

Stage 2 · Distinguish five clause functions

Name what the clause does in its host—not only the conjunction that introduces it.

4 minutes
STUDENT TASK
FunctionQuestion it answersModel
subjectWhat occupies the subject position?What the audit revealed changed the decision.
object / contentWhat is claimed, known or reported?The analyst confirmed that the dates differed.
complementWhat completes a noun, adjective or linking frame?The question is whether the evidence is complete.
relative modifierWhich person or thing?The figures that the supplier submitted were provisional.
adverbial modifierWhen, why, how or under what condition?The team paused the launch because two checks had failed.
  1. Assign one of the five functions to ten clauses.
  2. Name the host or sentence position.
  3. Distinguish an embedded question from a direct question.
  4. Explain whether the clause identifies, completes or circumstances another element.
  5. Reject one classification and justify the better analysis.
Finish evidenceFive function decisions supported by host evidence.
Teacher Help · Stage 2

Form and function can cross: a wh-clause may be a subject, object or complement. Accept alternative terminology if the learner identifies the same hierarchy and host relationship accurately.

Stage 3 · Keep each clause close to its host

Control distance, depth and source ownership before deciding whether to split the sentence.

5 minutes
STUDENT TASK
RiskHarder versionControlled version
reporter and source claims blurThe review says the supplier claimed the test failed, which is uncertain.The supplier claimed that the test had failed. The review says that this claim remains uncertain.
relative clause is far from hostThe team rejected the proposal after a long review that lacked cost evidence.After a long review, the team rejected the proposal, which lacked cost evidence.
three depths overload speechThe analyst believes that the claim that the supplier made after the audit was incomplete is misleading.The analyst considers the supplier’s post-audit claim misleading. She says the claim omitted key evidence.
  1. Rewrite six sentences while preserving every proposition.
  2. Keep each relative or complement clause close to its host.
  3. Name the owner of every claim.
  4. Limit depth where a second sentence improves processing.
  5. Explain what can be compressed and what must stay explicit.
Finish evidenceSix controlled rewrites with unchanged proposition maps.
Teacher Help · Stage 3

Splitting is a discourse choice, not a defeat. Keep one sentence when hierarchy supports the intended relationship; split when distance or depth makes the listener misassign source, scope or attachment.

Stage 4 · Repair four attachment or reference problems

Diagnose the likely wrong reading before making the smallest reliable repair.

  1. State the unintended or uncertain reading.
  2. Mark the clause’s intended host or antecedent.
  3. Repair word order, placement or reference.
  4. Preserve source ownership and scope.
  5. Read the result aloud and test one adversarial interpretation.
Finish evidenceFour minimal repairs with rejected readings.
Teacher Help · Stage 4

For sentence-relative which, require the learner to paraphrase the antecedent as a full event. If more than one event fits, replace which with an explicit noun such as this denial or this discrepancy.

Stage 5 · Listen across two accents and trace the hierarchy

Separate the speaker’s conclusion from each source’s claim, question and qualification.

5 minutes
STUDENT TASK
American English

Evidence and source ownership

Track matrix reporting clauses, embedded claims and the speaker’s final conclusion.

Australian English

Questions, conditions and qualifications

Track the unresolved question, its condition and the relative clause that identifies the evidence.

  1. Listen once and state the speaker’s main conclusion.
  2. Listen again and create a source → claim → qualification map.
  3. Identify one embedded question and one relative or adverbial clause.
  4. Flag the deepest point and decide whether it remains processable.
  5. Retell the explanation using one fewer layer without losing a proposition.
Finish evidenceTwo listening-based source and clause maps.
Teacher Help · Stage 5

The accents test meaning transfer, not imitation. Replay only where the learner loses source ownership, clause function, condition or reference; then ask for a proposition map before replaying the full explanation.

Stage 6 · Final Practice: deliver a precise multi-source explanation

Make the hierarchy audible: main conclusion first, then attributed evidence, qualification and unresolved question.

7 minutes
STUDENT TASK
FINAL PRACTICE

Sources → proposition map → hierarchy → explanation → challenge → retry

  1. Choose three short source notes that partly agree and partly conflict.
  2. Write notes only: source · claim · evidence · qualification · unresolved question · conclusion.
  3. Deliver a 75–90-second explanation with a visible matrix frame.
  4. Use at least three controlled embedded clauses with different functions.
  5. Keep each clause close to its host and every claim attached to its source.
  6. Split one sentence if a third layer would overload the listener.
  7. Your partner challenges: “Whose claim is that?” or “What does this clause modify?”
  8. After one feedback target, retry only the weakest hierarchy or reference point.
Performance rule: Embedding shows precise relationships; it must never blur source ownership, reference, certainty or scope.

Score the first independent performance

MEAN · MeaningEvery source, claim, qualification, condition and conclusion remains accurate and recoverable.
FORM · FormMatrix and embedded clauses, functions, word order, attachment and reference chains are controlled.
USE · Real useThe multi-source explanation is precise, processable and responsive to the listener’s challenge.
0 · Not yetThe clause hierarchy obscures source ownership, attachment, reference or the main conclusion.
1 · With supportThe explanation becomes clear after one prompt about host, source, word order, reference or sentence split.
2 · IndependentThe learner controls several clause functions, answers the challenge and repairs the weakest hierarchy without a prompt.

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

Finish evidenceOne 75–90-second multi-source explanation + one hierarchy-focused retry.
Teacher Help · Stage 6

Score the first independent attempt across MEAN, FORM and USE. Give one target only: matrix visibility, clause function, host distance, source ownership or reference. Keep the original score and record the retry separately.
