Why this lesson matters · เหตุผลที่เรียนบทนี้

For learners: Adapt one meaning-stable message for different relationships and channels while preserving facts, responsibility, commitment, deadline and action.

For teachers: The route moves from claim calibration to tactful distance and then register adaptation; ambiguity repair and C2 meaning-stable reformulation provide the next control and transfer steps.

Why this lesson matters

Professional English is not simply “formal” or “informal”. Effective speakers coordinate directness, pronouns, contractions, modality, voice, clause density and word choice for a relationship and channel. The message must sound appropriate while its facts, responsibility, commitment, deadline and action stay stable.

Teacher Lesson Plan

Write the meaning constants first: fact, responsible actor, commitment, deadline and action. Only then change the relationship and channel choices. A more formal sentence is not successful if it hides responsibility or weakens the required action.

Stage 1 · Diagnose audience, channel and purpose

Register begins with the situation, not with a list of formal words.

4 minutes
STUDENT TASK
AUDIENCEWho receives the message, and what is the relationship?
CHANNELChat, meeting, email, client call or permanent report?
PURPOSEBuild rapport, request action, record evidence or manage risk?
  1. Read six situations.
  2. Label familiarity, power distance and sensitivity.
  3. Identify whether the channel is conversational, client-facing or permanent.
  4. State the exact action the listener must understand.
  5. Rank each situation from conversational to formal and justify one borderline case.
Finish evidenceSix audience–channel–purpose profiles.
Teacher Help · Stage 1

Do not let the learner choose “formal” before naming audience and channel. A quick message to a senior colleague and a written incident record can both be careful, but they require different grammar and information packaging.

Stage 2 · Compare ten register choices

Treat register as a coordinated bundle, not one word swap.

4 minutes
STUDENT TASK
ChoiceMore conversationalMore formal or permanent
directnessCan you send it today?Please submit it by 4 p.m. today.
pronoun and actorWe missed one check.The review team did not complete the final check.
contractionWe can’t confirm it yet.We cannot confirm the result at this stage.
modalityMaybe we should wait.It may be advisable to postpone the decision.
verb and packagingWe looked into the problem.The issue was investigated.
  1. Compare ten paired choices: directness, pronouns, contractions, modality, active/passive voice, phrasal/formal verbs, clause density, nominalisation, reason placement and closing.
  2. Decide which version fits a colleague, client or report.
  3. Underline the actor and required action in each version.
  4. Reject two “formal” versions that become vague or unnecessarily distant.
Check the register decision

Formality does not automatically mean passive voice or long nouns. Keep an active actor when accountability matters. Use a more explicit deadline in a permanent channel, even when the tone remains courteous.

Finish evidenceTen choices with audience and meaning justifications.
Teacher Help · Stage 2

Ask what changed and what stayed constant. Accept more than one suitable answer when the learner can explain the relationship, channel and effect without changing the message.

Stage 3 · Preserve meaning across three reformulations

Change the relationship signal while protecting the proposition.

5 minutes
STUDENT TASK

Meaning constants

fact · responsible actor · commitment · deadline · required action

AudienceModel versionRegister work
colleagueCould you send me the revised figures by four? I need them for today’s client call.direct relationship, contraction possible, concise reason
clientCould you please send the revised figures by 4 p.m.? We need them to confirm today’s recommendation.courteous modal, explicit purpose, neutral relationship
formal recordThe client is requested to provide the revised figures by 4 p.m. so that the recommendation can be confirmed today.permanent record, explicit deadline and purpose
  1. Choose one base message with five meaning constants.
  2. Create colleague, client and report versions.
  3. Use at least two coordinated register changes in each version.
  4. Audit the five constants after every rewrite.
  5. Explain one choice you deliberately did not change.
Finish evidenceThree reformulations plus a five-point meaning audit.
Teacher Help · Stage 3

Cover the grammar labels only after the learner has compared meaning. If a passive version obscures the responsible actor, require the learner to restore the actor or choose an active clause.

Stage 4 · Repair register mismatch and meaning drift

Make the smallest repair that fits the audience without changing the decision.

5 minutes
STUDENT TASK
Problem lineRiskRepair target
Hey, send the contract now.too abrupt for a new clientcourteous request + clear deadline
It has been decided that action may perhaps be taken.actor and commitment disappearname decision-maker and required action
We regret to advise that the coffee machine is, at present, unavailable.over-formal for a team chatconcise colleague update
The payment issue was looked into and sorted.mixed register and unclear actorconsistent wording + accountable actor
  1. Identify the audience and channel for all four lines.
  2. Mark the register mismatch or meaning drift.
  3. Repair only the unreliable choices.
  4. Recheck fact, actor, commitment, deadline and action.
  5. Explain how the repair changes interpersonal effect but not the proposition.
Finish evidenceFour repairs with register and meaning explanations.
Teacher Help · Stage 4

Do not reward longer language. One repair should become less formal, one more courteous, one more accountable and one more internally consistent.

Stage 5 · Listen across two accents

Track what changes for audience and what must remain stable.

5 minutes
STUDENT TASK
Australian English

Three request versions

Compare directness, interpersonal framing, density and accountability across colleague, client and report versions.

British English

Three incident updates

Track the facts, responsible actor, commitment, deadline and action across the three channels.

  1. Listen once and identify the audience and channel of each version.
  2. Listen again and record two register signals per version.
  3. Write the five meaning constants.
  4. Flag one choice that becomes too distant or too casual.
  5. Retell the final message in a neutral version with full accountability.
Finish evidenceTwo audience–register–meaning maps.
Teacher Help · Stage 5

The two accents test meaning transfer, not accent imitation. Replay only the version where the learner loses the audience, responsible actor or required action.

Stage 6 · Final Practice: deliver one message three ways

Adapt for relationship and channel while preserving meaning and accountability.

7 minutes
STUDENT TASK
FINAL PRACTICE

Constants → colleague → client → report → challenge → audit → retry

  1. Choose a sensitive update about a delay, error, change or decision.
  2. Write notes only: fact · actor · commitment · deadline · action.
  3. Deliver a 30–45 second colleague version.
  4. Deliver a client version with appropriate courtesy and explicit purpose.
  5. Deliver a concise formal-record version.
  6. Your partner challenges one choice: “Does this still show who is responsible?” or “Has the required action changed?”
  7. Audit all five constants; after one feedback target, retry only the weakest version.
Performance rule: Change the relationship signal, not the facts, responsibility, commitment, deadline or action.

Score the first independent performance

MEAN · MeaningThe five constants remain stable and the audience can recover the same proposition in all three versions.
FORM · FormDirectness, pronouns, contractions, modality, voice, density and vocabulary form a consistent register bundle.
USE · Real useEach version fits its audience and channel; the learner explains one choice, answers the challenge and retries independently.
0 · Not yetRegister is mismatched, or a reformulation changes facts, actor, commitment, deadline or action.
1 · With supportThe three versions become appropriate and meaning-stable after one focused prompt.
2 · IndependentThe learner adapts all three versions, protects accountability, explains a choice and repairs the weak version without a prompt.

Result: 0–2 Rebuild · 3–4 Developing · 5–6 C1 mastery evidence.

Finish evidenceThree audience-specific versions + one meaning audit + one focused retry.
Teacher Help · Stage 6

Score the first independent attempt across MEAN, FORM and USE. Give one target only: audience fit, consistent register bundle, visible actor, stable commitment, explicit deadline or required action. Keep the original score and record the retry separately.
