Mixed-Skill Mastery · B2
Choose Well and Resolve a Shopping Problem
Evaluate product evidence, adapt to a changed constraint and negotiate a clear consumer resolution.
Why this lesson matters · เหตุผลที่เรียนบทนี้
For learners: Evaluate consumer evidence, adapt after new constraints and negotiate a defensible final resolution.
For teachers: Reading, listening, evidence use, recommendation, negotiation and two changed constraints culminate in independent mastery.
สำหรับผู้เรียน: ประเมินหลักฐานผู้บริโภค ปรับเมื่อมีข้อจำกัดใหม่ และเจรจาทางออกสุดท้ายที่มีเหตุผล
สำหรับครู: รวมการอ่าน ฟัง ใช้หลักฐาน แนะนำ เจรจา และปรับตามข้อจำกัดสองรอบ เพื่อจบด้วยผลงานอิสระ
Your Goal
Evaluate two products against a buyer brief, separate verified evidence from seller claims and unknowns, justify a purchase, adapt after a stock or warranty change, resolve a new product problem, and confirm the final agreement independently.

Teacher Lesson Plan · Read before class
Do not let the learner invent durability tests, airline approval or warranty coverage. Require a source for each claim, a proportionate solution and a complete final confirmation.
| Time | Teacher does | Student does | Evidence |
|---|---|---|---|
| 0–3 | Frames a defensible consumer decision. | Ranks buyer constraints. | A decision standard. |
| 3–7 | Reveals written product evidence. | Records facts, claims and unknowns. | An evidence table. |
| 7–12 | Challenges the initial choice. | Compares trade-offs and justifies. | A provisional decision. |
| 12–17 | Plays the stock/warranty update. | Revises the decision and asks questions. | An adapted position. |
| 17–23 | Roleplays the manager. | Negotiates a practical purchase plan. | A confirmed agreement. |
| 23–30 | Plays a fresh problem and scores. | Resolves, adapts and confirms independently. | EVD/ADAPT/FP. |
1. Frame a defensible decision
3 minBuyer brief
Nora needs one carry-on for a business trip tomorrow. Airline cabin limit: 10 kilograms total. She will use stairs, expects rain, carries a laptop and clothes, and has a 4,500-baht budget.
STUDENT TASK
- Rank weight, capacity, rain protection, movement, warranty and price.
- Name one non-negotiable constraint.
- State what evidence would justify paying more.
Teacher Help
Keep the decision standard tied to tomorrow’s trip and the ten-kilogram total. Do not discuss brands or personal taste.
2. Read and classify the product evidence
4 min| Product | Verified specification | Seller statement | Price / warranty |
|---|---|---|---|
| Flex Case | 2.7 kg; 38 L; polycarbonate shell; four double wheels | “Designed for frequent travel” | 4,290 baht; display card says three-year limited shell/wheel warranty |
| Metro Lite | 2.1 kg; 42 L; polyester body; two wheels; rain cover included | “Easy to carry anywhere” | 3,590 baht; two-year zip/wheel warranty |
STUDENT TASK
- Record four verified differences.
- Mark both seller statements as claims, not proof.
- List two important unknowns, including laptop protection or airline dimensions.
You are ready whenYou can label every point as verified, claimed or unknown.
Teacher Help
Ask ‘Where does that information come from?’ Keep airline cabin dimensions unknown because the case gives only a weight limit.
3. Evaluate the trade-offs and choose provisionally
5 minSTUDENT TASK
- Calculate the remaining luggage allowance after bag weight.
- Connect at least three specifications to Nora’s trip.
- Explain one benefit and one risk for each case.
- Choose provisionally and state two conditions before purchase.
Decision routeBecause the buyer must ____, the most relevant evidence is ____. I would provisionally choose ____; however, I need to verify ____ and ____.
You are ready whenThe choice follows the buyer brief and names its remaining uncertainty.
Teacher Help
Challenge price-only reasoning. A B2 answer weighs evidence, uncertainty and the cost of a poor fit.
4. Listen and update the decision

Transcript · open after the task
Here is the stock update. The black Flex Case is available today, but its wheel warranty now covers manufacturing faults for one year, not three. The grey Metro Lite arrives on Friday and includes a two-year zip and wheel warranty. A ten percent discount is available only on the Metro Lite. The buyer must travel tomorrow morning.
STUDENT TASK
- Record the stock, warranty and discount changes.
- Identify which printed claim is now outdated.
- Re-rank availability, warranty and price.
- Keep, reverse or qualify the purchase decision.
- Ask the manager for written confirmation of the final warranty.
You are ready whenYour revised decision responds to tomorrow’s departure and the corrected warranty.
Teacher Help
Play twice. Require the learner to reject the outdated three-year display claim and request written terms before final purchase.
5. Negotiate a practical purchase plan
6 minSTUDENT TASK
- Present the buyer brief and evidence-led choice in 60–75 seconds.
- Explain the main trade-off and remaining unknown.
- Request a written warranty and a final product check.
- Ask whether the display model has been used or repaired.
- Accept, reject or condition the offer.
- Confirm product, price, warranty, collection time and return process.
Negotiation route—not a scriptGiven ___, I am leaning towards ___. The evidence shows ___, but I still need to verify ___. I can proceed provided that ___. To confirm, the final agreement is ___.
Teacher Help
Roleplay the manager and answer only precise questions. Require the learner to recap all five agreement fields before closing.
6. Final Practice · resolve a damaged-item constraint
7 minAudio 2 · Australian English · Olivia
Transcript · open after the task
New problem: the customer chose the Flex Case, but one wheel is sticking during the final check. There is no replacement in stock. The store can repair the wheel in two days, provide the display model with a written inspection record, or issue a full refund today. The customer still needs a bag for tomorrow’s flight and cannot exceed the airline’s ten kilogram cabin limit.
INDEPENDENT MIXED-SKILL PERFORMANCE
- Separate the verified fault, manager options, buyer constraint and unknowns.
- Explain why the original purchase cannot proceed unchanged.
- Evaluate repair, display model and refund against tomorrow’s trip.
- Choose a proportionate resolution and request the evidence needed.
- Confirm product or refund, price, warranty/inspection record, timing and receipt.
- Teacher adds one new constraint: the display model weighs 3.1 kg. Adapt immediately.
- After one feedback point, retry only the weakest 30-second section.
Final Practice evidence
EVD · Evidence useSeparates verified fault, options, constraints, unknowns and claims accurately.
ADAPT · AdaptationRevises priorities and the solution after each new constraint.
FP · Final performanceChooses, negotiates and confirms a workable outcome independently.
Teacher scoring guide
Score the first unsupported performance, then score the focused 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 sentence. Natural hesitation is acceptable.
Target: 5/6 overall with FP = 2 and no zero.
The lesson is complete whenYou independently evaluate, adapt, resolve and confirm the consumer decision.
Teacher Help · scoring and retry
Do not supply the solution. Add the 3.1-kilogram constraint only after the first agreement, record exact EVD/ADAPT/FP evidence and allow one focused retry.
