คำอธิบายภาษาไทย
หา head noun ให้ได้ 5 คำ เติมรายละเอียดหน้าและหลังเฉพาะส่วนที่ช่วยระบุหรือประเมิน แก้วลีที่ใส่ข้อมูลมากเกินไป 3 จุด และบรรยายวิธีแก้ปัญหาหนึ่งอย่างให้ชัดภายใน 60 วินาที
Why this lesson matters
Useful descriptions depend on a visible head noun and controlled detail. Too little information leaves the listener guessing; too many stacked modifiers hide the central noun or attach to the wrong idea.
ภาษาไทย: คำบรรยายที่ดีต้องทำให้เห็น head noun ชัดและเติมรายละเอียดพอดี ข้อมูลน้อยเกินไปทำให้เดา แต่ข้อมูลซ้อนมากเกินไปจะบังคำนามหลักหรือทำให้รายละเอียดไปขยายผิดสิ่ง

Teacher Lesson Plan
The head noun comes first. Before adding or correcting a modifier, confirm which noun carries the message and what the listener needs to identify or evaluate it.
| Stage | Teacher move | Evidence to collect |
|---|---|---|
| 1 · Head | Strip five phrases to their central nouns and classify surrounding detail. | Five head-noun maps |
| 2 · Before | Add short type, purpose, material and quality detail in a natural order. | Five controlled expansions |
| 3 · After | Attach prepositional, relative, participle and infinitive information to the intended noun. | Four attachment decisions |
| 4 · Repair | Remove, reorder or split three overloaded phrases. | Three justified repairs |
| 5 · Transfer | Recover phrase structure across American and British accents. | Two listening maps + first recommendation |
| 6 · Perform | Score MEAN/FORM/USE and target one density or attachment retry. | 60-second description + retry |
Stage 1 · Find the head noun before reading the detail
Strip five phrases to their centre, then decide what each surrounding detail contributes.
STUDENT TASK
BEFOREDeterminer, purpose, type, material or quality.
HEAD NOUNThe central person, thing, place, service or idea.
AFTERRelationship, action, purpose or identifying clause.
- Underline the head noun in these five phrases: a compact air purifier for small rooms; the new customer-support process introduced last month; two reusable glass bottles with protective sleeves; an easy-to-update booking system; the colleague responsible for supplier checks.
- Box the details before each head noun and circle the details after it.
- Remove all modifiers and say what central meaning remains.
- Restore only the details needed to identify or evaluate each noun.
Meaning first: In “a compact air purifier for small rooms,” purifier is the head; the other words specify which kind and who it suits.
Finish evidenceFive accurate head-noun maps with useful detail classified.
Teacher Help · Stage 1
Do not ask learners to memorise an adjective-order list first. Make the head noun audible and visible, then ask what each modifier adds and whether the listener genuinely needs it.
Stage 2 · Add compact detail before the head noun
Choose only the short details that help the listener classify or evaluate the noun.
STUDENT TASK
| Detail job | Compact form | Controlled noun phrase |
|---|---|---|
| purpose | customer-support | a customer-support tool |
| type/source | cloud-based | a cloud-based booking system |
| material | recycled-plastic | a recycled-plastic case |
| quality/size | reliable compact | a reliable compact purifier |
- Expand the five head nouns from Stage 1 with one or two useful premodifiers.
- Explain the job of every added word.
- Remove repeated or decorative details that do not change identification or evaluation.
- Read each phrase aloud and keep the head noun easy to hear.
Check the compact-detail rule
Short classifying details usually stay close to the head noun. When several adjectives compete, keep the clearest purpose/type/material/quality information and move longer explanations after the noun.
Finish evidenceFive relevant premodifier expansions around clear head nouns.
Teacher Help · Stage 2
Ask “Does this word identify, classify or evaluate?” Remove any modifier the learner cannot justify. Natural order matters, but relevance and an audible head noun come first.
Stage 3 · Attach longer detail after the head noun
Choose a postmodifier that connects clearly to the intended noun and information job.
STUDENT TASK
| Information job | Postmodifier form | Clear model |
|---|---|---|
| relationship/location | prepositional phrase | a purifier for small meeting rooms |
| essential identity | relative clause | the filter that removes fine particles |
| active/passive action | participle phrase | the data collected during the trial |
| purpose/next action | to-infinitive phrase | an easy dashboard to update each week |
- Add one different postmodifier form to four head nouns.
- Draw an arrow from each postmodifier to the noun it modifies.
- Check that the added information identifies, explains or evaluates that noun.
- Move any extra comment into a new clause.
Check the attachment rule
Keep the postmodifier beside the noun it describes. If another noun stands between them or two attachments are possible, repeat the head noun or split the message.
Finish evidenceFour postmodifier attachments with one clear noun target each.
Teacher Help · Stage 3
Require an attachment arrow before correcting form. A fluent relative or participle phrase still fails when it can describe two nouns. Split the message whenever proximity does not protect the meaning.
Stage 4 · Repair three overloaded noun phrases
Protect the head noun and attachment by removing, reordering or splitting information.
STUDENT TASK
| Overloaded phrase | Main risk | Repair decision |
|---|---|---|
| a new small efficient office air cleaning solution for teams working long hours with simple controls | head noun and purpose are buried | a compact office air purifier with simple controls; it suits teams working long hours |
| the customer data security review process introduced by the team working in Bangkok | noun stack and unclear attachment | the process for reviewing customer-data security, introduced by the Bangkok team |
| an easy to use weekly updated booking tool for new teachers | competing adjective and participle relationships | an easy-to-use booking tool for new teachers that is updated weekly |
- Underline the head noun in all three phrases.
- Label the risk: buried head, repeated meaning, unnatural order or unclear attachment.
- Repair each phrase by removing, reordering or splitting.
- Read the original and repair aloud; choose the version the listener can process once.
- Create one overloaded phrase from your own context and repair it.
Check the three repair principles
1 keep the head noun audible · 2 keep modifiers beside the noun they describe · 3 move extra evaluation or background information into a new clause.
Finish evidenceThree required repairs plus one transfer repair.
Teacher Help · Stage 4
Do not reward the shortest answer automatically. A successful repair preserves the necessary identity and evaluation while making the head noun and modifier relationships easier to recover.
Stage 5 · Listen, unpack and make a first recommendation
Recover head nouns and modifier relationships across American and British English.
STUDENT TASKAmerican English · Matthew British English · Amy
Product recommendation
Identify which details define the product and which details evaluate it.
| Listening pass | Record | Clarity decision |
|---|---|---|
| 1 · Situation | solution, user and need | what central noun matters? |
| 2 · Structure | before → head → after | which detail attaches where? |
| 3 · Density | essential vs extra detail | keep, remove or split? |
- Listen to Matthew once for the solution and again to map each phrase.
- Repeat with Amy; do not imitate the accent.
- Retell one expanded noun phrase from each recording and name its head.
- Give your first 45-second recommendation with three expanded noun phrases.
- Your partner identifies one crowded or unclear phrase; simplify it without losing the key detail.
Finish evidenceTwo listening maps, one first recommendation and one live density repair.
Teacher Help · Stage 5
Audio never starts automatically. Accent variety tests transfer, not imitation. Replay only the phrase where the learner loses the head or attachment, then ask the learner to rebuild it as before–head–after.
Stage 6 · Final Practice: describe one solution and retry
Give a precise 60-second recommendation without hiding the head nouns or overloading the listener.
STUDENT TASK
FINAL PRACTICE
Need → solution → head → useful detail → simplification → retry
- Name one real learner, customer, team or household need.
- Choose one product, service, process or solution and plan notes only.
- Describe it for 60 seconds with exactly three expanded noun phrases.
- Make each head noun easy to hear; use at least two useful premodifiers and two different postmodifier forms overall.
- Include one deliberately simplified sentence so the listener can process the key recommendation.
- Your partner names one phrase that is crowded, weak or ambiguously attached.
- Repair it by removing, reordering or splitting, then retry only that part.
Performance rule: Precision means every detail earns its place and attaches to one clear head noun.
Score the first independent performance
MEAN · MeaningEvery detail helps the listener identify or evaluate the intended product, service, process or solution.
FORM · FormFive head-noun decisions, premodifiers and postmodifiers form clear phrases with secure attachment.
USE · Real useThe learner recommends one solution precisely for 60 seconds and simplifies one overloaded phrase independently.
0 · Not yetThe head noun or modifier relationship is hidden, so the listener cannot recover the intended solution.
1 · With supportThe description becomes clear after one prompt to name the head, remove a detail, reorder or split the phrase.
2 · IndependentThree precise noun phrases and the simplified sentence remain clear, relevant and easy to process without a prompt.
Result: 0–2 Rebuild · 3–4 Developing · 5–6 B2 mastery evidence.
Finish evidenceFive head-noun maps + relevant expansion + three required repairs + one 60-second solution description + one focused retry.
Teacher Help · Stage 6
Score the first independent performance across MEAN, FORM and USE. Give one target only: head visibility, modifier relevance, natural order, attachment or information density. Keep the original score and record the focused retry separately.
