C2 Integrated Mastery: Precise, Flexible, Audience-Aware Communication
Integrate the full C2 grammar system to analyse evidence, design information, calibrate stance, adapt register, respond live, and self-repair during a high-stakes communication task.
Integrated C2 grammar control

C2 mastery ไม่ได้วัดจากการใช้โครงสร้างยากมากที่สุด แต่วัดการเลือก form ให้ตรง meaning, evidence, audience และ purpose พร้อมปรับใหม่และแก้เองได้เมื่อความหมาย ความสัมพันธ์ หรือความชัดเริ่มคลาดเคลื่อน
Your goal
By the end of this lesson, you can plan a complete C2 response, deliver and reformulate a decision briefing for two audiences, respond to challenge, produce a formal record, and verify your own language independently.

Progress focus LCFP
Control the target pattern so the intended meaning remains clear.
Complete the lesson’s real communication outcome without teacher-supplied sentences.
Your grammar path
Coordinate viewpoint, stance, focus, voice, clause and noun density, conditionality, cohesion, register, and rhetoric, keeping a repair alternative ready.
Deliver the briefing, reformulate for a second audience, answer a challenge diplomatically, create a concise formal record, and audit the full performance.
30-minute lesson route
Model evidence, audience, and invariants

Extract facts, source strength, actors, alternatives, conditions, risks, timeline, audience knowledge, relationship, and action from the case brief.
How to run Stage 1
3 min: Build the evidence, audience, risk, and invariant plan.
Use the least complex sufficient structure
Choose viewpoint, stance, focus, voice, clause or noun density, conditional form, cohesion, register, and one rhetorical device, then prepare a simpler reformulation.
How to run Stage 2
5 min: Select the least complex sufficient grammar bundle and repair alternative.
Maintain precision under interaction pressure
Engduo Audio: Listen for meaning first. Audio never starts automatically.
Map evidence, concession, focus, stance, condition, scope, and recommendation.
Prepare a fair concession, evidence boundary, conditional alternative, responsibility statement, and audience-appropriate response.
Deliver a 90-second evidence briefing and answer one challenge with fair concession, explicit boundary, calibrated stance, and a testable alternative.
How to run Stage 3
5 min: Run the primary briefing and live stakeholder challenge.
Adapt to new evidence and a new audience
Listen to both clips, revise the recommendation if required, and transform the core decision for a less expert or differently positioned audience without changing the evidence.
How to run Stage 4
6 min: Play both clips, update the plan, and reformulate for a second audience.
Complete the multi-audience performance
Deliver the adapted 60-second version, produce a 60-word formal decision record, and identify one self-repair that improved meaning, audience fit, or processing.
How to run Stage 5
7 min: Run the adapted delivery and 60-word formal decision record.
Final practice: Integrate precision, flexibility, audience awareness, and independent repair
Task: Analyse a high-stakes case, deliver an evidence briefing, respond to challenge, reformulate for a second audience, and produce a formal decision record while preserving facts, stance, responsibility, conditions, and action.
Success: Grammar choices serve meaning and audience, evidence and uncertainty remain calibrated, information is easy to process, register adaptation preserves invariants, challenge is handled fairly, and monitoring produces an accurate independent repair.
LC · Language Control
0 Frequent form problems obscure the intended meaning.
1 Meaning remains clear with some prompting or self-correction.
2 Integrates C2 viewpoint, stance, information structure, reformulation, clause and noun control, conditional nuance, cohesion, register, rhetoric, accuracy monitoring, and self-repair.
FP · Functional Performance
0 Does not yet complete the communication outcome.
1 Completes most of the outcome with visible prompts.
2 Completes a high-stakes multi-audience decision communication independently across briefing, challenge, reformulation, formal record, and verified repair.
How to run Stage 6
4 min: Score integrated LC and FP, verify invariants, repair one high-value issue, and retry it.

เริ่มจาก evidence และ audience map ไม่ใช่รายชื่อ grammar เลือกโครงสร้างที่ง่ายที่สุดแต่พอสำหรับ meaning เตรียม reformulation ที่ง่ายกว่าไว้หนึ่งแบบ ระหว่างตอบ challenge ให้รักษา fact, uncertainty, actor, condition และ action แล้วตรวจทั้งงานด้วย LC และ FP
