Why this lesson matters · เหตุผลที่เรียนบทนี้

For learners: Evaluate restaurant quality, value, and dietary evidence before making and revising a careful recommendation.

For teachers: The lesson separates evidence types, supports a calibrated judgement, challenges one claim, then changes the evidence so the learner must revise independently.

สำหรับผู้เรียน: ประเมินหลักฐานด้านคุณภาพ ความคุ้มค่า และข้อมูลอาหารก่อนให้และปรับคำแนะนำอย่างรอบคอบ
สำหรับครู: บทเรียนแยกประเภทหลักฐาน สร้างคำตัดสินแบบระมัดระวัง ท้าทายข้ออ้างหนึ่งจุด แล้วเปลี่ยนหลักฐานเพื่อให้ผู้เรียนปรับคำแนะนำอย่างอิสระ

Your Goal

Distinguish fact, personal experience, inference and unsupported claim; compare two restaurants on quality, value and dietary evidence; make a calibrated recommendation; respond to one challenge; and revise the judgement after new evidence.

คำอธิบายเป้าหมายภาษาไทย

แยกข้อเท็จจริง ประสบการณ์ส่วนบุคคล ข้ออนุมาน และคำกล่าวที่ไม่มีหลักฐาน เปรียบเทียบร้านสองแห่งด้านคุณภาพ ความคุ้มค่า และข้อมูลอาหาร ให้คำแนะนำแบบระมัดระวัง ตอบข้อท้าทาย และปรับคำตัดสินเมื่อมีหลักฐานใหม่

Why this lesson matters · ทำไมบทนี้จึงสำคัญ

For learners: At B2, “good” and “cheap” are not enough. A responsible recommendation explains the evidence, its limits, and how strongly the conclusion can be stated.

For teachers: This support lesson isolates evaluation language before the learner must resolve a live quality or dietary problem in the B2 mastery task.

สำหรับผู้เรียน: ระดับ B2 ต้องอธิบายว่าหลักฐานคืออะไร มีข้อจำกัดอะไร และควรสรุปหนักแน่นเพียงใด ไม่ใช่แค่บอกว่าดีหรือถูก
สำหรับครู: บทสนับสนุนนี้แยกฝึกภาษาการประเมินก่อนนำไปใช้แก้ปัญหาคุณภาพหรืออาหารในบท Mastery

Teacher Lesson Plan · Read before class

This is a speaking lesson, not a review-reading lesson. Limit silent reading, require an evidence source after each claim, hide models after selection, and keep learner talk time above 70%.

Time	Teacher does	Student does	Required result
0–3	Assigns the diner decision.	Defines criteria and evidence threshold.	A clear decision question.
3–7	Reveals four statement types.	Classifies and calibrates them aloud.	Evidence discipline.
7–12	Reveals two evidence sets.	Compares quality, value and dietary evidence.	Traceable claims.
12–17	Removes the model.	Gives a balanced recommendation.	A connected B2 judgement.
17–21	Challenges one weak claim.	Defends, qualifies or withdraws it.	Two-way evaluation.
21–27	Adds verified evidence.	Revises the judgement meaningfully.	Evidence-led adaptation.
27–30	Sets a fresh profile and scores.	Completes an unsupported evaluation and retry.	Independent evidence.

1. Define the decision

3 min

Start with the diner and the decision. The same restaurant can be strong for one purpose and weak for another.

Group

Four colleagues want an early dinner and a quiet work conversation.

Needs

One diner has a strict dairy allergy. All need a clear dietary-information process.

Budget

Up to 1,400 baht for four main courses; drinks are separate.

STUDENT TASK

State the decision in one sentence.
Rank quality, value, atmosphere and dietary evidence for this group.
Explain what evidence would be strong enough for a recommendation.

You are ready whenYour criteria fit this group rather than a general idea of a “good restaurant.”

Teacher Help

Ask “Good for whom, for what purpose, and based on what?” Do not reveal the restaurant evidence until the learner has ranked the criteria.

2. Sort evidence and claims

4 min

Different statements deserve different levels of confidence.

Verified fact

Recorded by a named source or directly confirmed.

Experience

A person’s report from a particular visit.

Inference

A reasonable conclusion that still needs qualification.

Unsupported claim

A broad statement without enough evidence.

STUDENT TASK

Classify: “A service inspection scored the restaurant 4 out of 5.”
Classify: “Our server was slow last Friday.”
Classify: “It may be quieter before seven.”
Classify: “This is the best restaurant in town.”
Restate the final two claims with an appropriate level of certainty.

Calibration tools
The evidence indicates … · This suggests …, although … · Based on one report … · I cannot confirm … · It would be reasonable to … provided that …

You are ready whenYou can state how strong each claim is and why.

Teacher Help

Do not turn this into a definition test. After each label, ask the learner to say a complete restaurant sentence with suitable certainty. Hide the tools after ninety seconds.

3. Compare two restaurants

5 min

Use the source and date as part of the evidence. A high score is not automatically relevant to this group.

Evidence area	Harbour Kitchen	The Green Room	Strength / limitation
Price	Main courses: 280–360 baht	Main courses: 220–300 baht	Current menu facts; both can fit the budget with careful choices.
Quality reports	4.5/5 from 126 verified diner reports; portions and service described consistently	4.3/5 from 310 verified reports; occasional service delays	Useful pattern, but reports describe different visits and expectations.
Atmosphere	Frequently described as busy after 7:30	Frequently described as quiet on weekday evenings	Relevant to conversation; timing still matters.
Dietary information	Dietary symbols reviewed quarterly; cross-contact requires a call	Plant-based dishes and ingredients listed; kitchen procedure unconfirmed	Neither source confirms safety for a strict dairy allergy.
Inspection	Cleanliness 5/5; service 4/5; two months ago	Cleanliness 4/5; service 4/5; eight months ago	Named evidence; recency differs.
Promotion	“The finest dining experience in town”	“We meet every dietary need”	Unsupported marketing claims.

STUDENT TASK

Give one supported comparison for quality, value and atmosphere.
Explain which inspection evidence is stronger and why.
Identify two claims that must not be repeated as facts.
State what remains unknown about the dairy allergy.

You are ready whenEvery comparison identifies its source, relevance and limitation.

Transcript

Based on the evidence provided, Harbour Kitchen offers better overall value. Its main courses cost slightly more, but the portions and service standards are consistently described in verified diner reports. The main limitation is the busy evening atmosphere. For a relaxed conversation, I would recommend an earlier booking rather than making an unconditional claim about quality.

Transcript

The Green Room lists several plant-based dishes, but that does not prove that every item is suitable for a strict dairy allergy. The menu identifies ingredients, while the kitchen procedure remains unconfirmed. I would describe it as a promising option, not a guaranteed safe choice, and contact the restaurant before recommending it to this diner.

Teacher Help

Ask “Which source supports that?” after each claim. Keep audio closed until the learner has completed their own comparison. The audio is a language reference, not a listening score.

4. Build a calibrated judgement

5 min

A B2 recommendation connects the decision to evidence, acknowledges a limitation and identifies a condition or next check.

STUDENT TASK

Choose one restaurant for the four colleagues—or delay the decision.
Use two relevant pieces of evidence from different sources.
Acknowledge one limitation in your preferred option.
Explain why the other option is currently weaker for this group.
Finish with one condition or checking action.

Judgement shape—not a script
On balance, ___ appears more suitable because ___ and ___. The evidence is reasonably strong because ___. However, ___. I would recommend it provided that ___; otherwise, ___.

You are ready whenYour 60-second judgement is balanced, traceable and appropriately cautious.

คำช่วยภาษาไทย

สรุปทางเลือกโดยใช้หลักฐานต่างแหล่งอย่างน้อยสองชิ้น บอกข้อจำกัดของตัวเลือกที่เลือก อธิบายว่าทำไมอีกตัวเลือกจึงอ่อนกว่าในบริบทนี้ และจบด้วยเงื่อนไขหรือสิ่งที่ต้องตรวจเพิ่ม

Teacher Help

Allow keyword planning only. Hide the shape after the first attempt. Challenge absolute adjectives such as safest, best and guaranteed unless the evidence supports them.

5. Respond to a challenge

4 min

A credible judgement can survive a question without becoming defensive or vague.

Challenge A

“Harbour costs more. How can you call it better value?”

Challenge B

“The Green Room says it meets every dietary need. Why are you still uncertain?”

STUDENT TASK

Give your judgement without the model.
Listen to one teacher challenge.
Acknowledge the valid concern.
Defend, qualify or withdraw one claim.
State what evidence would change your mind.

You are ready whenYour response improves the precision of the judgement rather than repeating it.

Teacher Help

Select the challenge that targets the learner’s weakest evidence link. Reward a responsible qualification or changed conclusion; the learner does not have to defend the original recommendation.

6. Revise after new evidence

6 min

New verified information should change the weight of the evidence—not merely add another sentence.

Update 1 · Harbour Kitchen

A manager confirms that the kitchen cannot prevent dairy cross-contact during evening service.

Update 2 · The Green Room

A manager confirms a separate dairy-free preparation area by phone; a service inspection from last week scored 5/5.

STUDENT TASK

State which earlier claims remain valid.
Explain which uncertainty has been resolved and which option is now weaker.
Revise the recommendation with two updated evidence links.
Preserve one limitation that still matters.
Answer: “Did the restaurant become better, or did the evidence become stronger?”

You are ready whenYour revised version changes for a clear evidential reason and does not erase remaining limitations.

Teacher Help

Require a contrast between the first and revised judgement. If the learner says the restaurant itself became better, ask what actually changed: the service or the available evidence.

7. Final Practice · prove the evaluation

3 min

Hide the models. Complete a fresh 75–90 second evaluation independently.

FINAL PRACTICE

Teacher changes the group’s priority to either lowest price or quiet atmosphere.
Compare both restaurants using at least three relevant evidence points.
Recommend one option or delay the decision.
State one limitation and one unknown fact.
Respond to one challenge.
Teacher adds one new verified fact; revise the judgement and retry the weakest 30-second section.

COM · CommunicationThe judgement, evidence chain, limitation and challenge response are easy to follow.

VR · Vocabulary rangeQuality, value, dietary evidence and calibration language fit the strength of the evidence.

FP · Final performanceThe learner revises the recommendation appropriately after new evidence.

Teacher scoring guide

Score the unsupported Final Practice, then score the retry separately.

0 · Not yetThe criterion is not demonstrated after one clear prompt.

1 · With supportThe criterion is partly demonstrated or needs supplied language.

2 · IndependentThe criterion is clear without a model or supplied line.

Target: 5/6 overall with no zero. Use the lowest focus as the retry target.

The lesson is complete whenYou make and revise one evidence-based restaurant recommendation independently.

Teacher Help · scoring and retry

Observe the complete first attempt without interruption. Record exact COM, VR and FP evidence, add one relevant verified fact, give one success and one next target, then allow one focused retry.

Teaching reference

The CEFR Companion Volume informs the B2 focus on developing a clear argument, evaluating options, qualifying claims, responding to a challenge and adapting a recommendation.
