Research synthesis
Track what three sources claim, concede, challenge and recommend.

Choose verbs that preserve what three sources assert, concede, challenge and recommend—without exaggerating their position.
For learners: Preserve each source’s stance, commitment and evidence limit while synthesising three positions with accurate reporting-verb complements.
For teachers: C1 progression from 12 source-move classifications through 10 justified verb choices and four complement families to an independent three-position synthesis, verb defence and focused retry.
สำหรับผู้เรียน: รักษาท่าที ระดับความรับผิดชอบ และข้อจำกัดของหลักฐานจากแต่ละแหล่ง พร้อมสังเคราะห์สามจุดยืนด้วย reporting verbs และ complement ที่ถูกต้อง
สำหรับครู: เส้นทางระดับ C1 เริ่มจากจำแนกการสื่อสารของแหล่งข้อมูล 12 ข้อ เลือกกริยา 10 คำอย่างมีหลักฐาน ใช้ complement 4 กลุ่ม และจบด้วยการสังเคราะห์สามจุดยืน การอธิบายเหตุผลของกริยา และการลองใหม่เฉพาะจุด
Classify twelve source moves, choose ten accurate reporting verbs, complete four complement families, and deliver a balanced synthesis of three positions.
จำแนกเจตนาของแหล่งข้อมูล 12 ข้อ เลือก reporting verb ที่ตรงความหมาย 10 คำ ใช้โครงสร้างส่วนเติมเต็ม 4 กลุ่ม และสรุปจุดยืนของแหล่งข้อมูล 3 ฝ่ายอย่างสมดุล โดยไม่เพิ่มหรือลดน้ำหนักของต้นฉบับ
At C1, reporting verbs are evidence decisions. Claims, acknowledges, concedes, denies and warns do not describe the same relationship to a proposition. A polished synthesis fails if the verb changes the source’s commitment, hides a limitation or assigns an action to the wrong person.
ภาษาไทย: ในระดับ C1 การเลือก reporting verb คือการตัดสินใจเกี่ยวกับน้ำหนักและท่าทีของหลักฐาน คำกริยาที่ต่างกันอาจทำให้ผู้พูดดูมั่นใจ ยอมรับ ปฏิเสธ หรือเตือนต่างจากต้นฉบับได้ แม้ประโยคจะถูกไวยากรณ์ก็ตาม
Source meaning comes first. Confirm the original move and degree of commitment before correcting the complement pattern. Do not reward a sophisticated verb that the source does not justify.
| Stage | Teacher move | Evidence to collect |
|---|---|---|
| 1 · Classify | Separate move, commitment and limitation. | 12 source-move cards |
| 2 · Calibrate | Contrast verbs that strengthen, soften or position a claim. | 10 justified verb choices |
| 3 · Form | Build four complement families from meaning. | 12 accurate reports |
| 4 · Repair | Reverse stance, source and pattern distortion. | 6 defensible repairs |
| 5 · Transfer | Recover three positions across two accents. | 2 source maps |
| 6 · Perform | Score MEAN/FORM/USE and target one retry. | Synthesis + defence + retry |
Identify what each source does before choosing a reporting verb.
| Source wording | Move to test | Meaning that must survive |
|---|---|---|
| “The evidence strongly supports X.” | argue / maintain | reasoned, committed position |
| “X may help, although the sample is small.” | acknowledge / concede | limited acceptance |
| “We did not alter the records.” | deny | rejection of responsibility |
| “Do not generalise beyond this group.” | warn / caution | risk and boundary |
Ask “Which exact words make this a concession rather than an admission?” Accept alternatives only when the learner can point to evidence. A personal opinion about the source is not evidence for the reporting verb.
Calibrate the distance between neutral attribution and evaluative reporting.
| Communicative move | Useful verbs | Critical difference |
|---|---|---|
| present a position | state · claim · argue · maintain | neutral statement vs unsupported claim vs reasoned/continued position |
| accept a limit or responsibility | acknowledge · concede · admit | recognise a fact vs yield a point vs accept responsibility |
| reject or contest | deny · dispute · challenge | reject an allegation vs question truth vs test an assumption |
| direct future action | recommend · advocate · warn · caution | propose, publicly support, signal danger or set a limit |
Argues needs reasoning; claims does not automatically mean false; concedes signals a reluctant or contrastive acceptance; admits assigns stronger responsibility; warns requires a risk.
Ban thesaurus substitution. The learner must justify each verb from the source’s communicative action. If the evidence cannot distinguish states from argues, retain the more neutral option.
Match the grammar to the selected verb without losing speaker, action or negation.
| Complement family | Pattern | Accurate model |
|---|---|---|
| 1 · that-clause | verb + that + clause | The review argues that the benefit is limited. |
| 2 · -ing clause | verb + -ing | The supplier denied changing the record. |
| 3 · to-infinitive | verb + to + base | The team agreed to release the data. |
| 4 · object frame | verb + object + to / of + -ing | The panel warned researchers not to generalise. · The report accused the firm of hiding costs. |
Correct in this order: source ownership, speech act, then complement. Contrast recommend doing / recommend that someone do with advise someone to do; contrast deny doing with refuse to do.
A grammatical sentence can still misrepresent the source.
| Distorted report | Hidden problem | Responsible repair target |
|---|---|---|
| The authors prove that the policy works. | qualified support becomes proof | argue that it may work in… |
| The director admitted that costs could rise. | forecast becomes acceptance of fault | warned that costs could rise |
| The review recommends us to expand. | invalid complement | recommends expanding / that we expand |
| The supplier denied to alter the file. | invalid complement | denied altering the file |
| The panel conceded that the method was effective. | no contrast or reluctant acceptance in source | stated / reported that… |
| The report accused hiding the limitation. | person and preposition missing | accused the team of hiding… |
Reject repairs that fix only the form. Ask who now owns the position, how committed the source sounds and whether the new verb introduces evaluation not present in the original.
Recover source, move, verb, complement and relationship from two C1 summaries.
Track what three sources claim, concede, challenge and recommend.
Track the verb, complement family, evidence limit and relationship between positions.
Audio never starts automatically. Accent variety tests source-tracking transfer, not imitation. Replay only the sentence where the learner loses the source, stance, complement or relationship.
Balance sources, defend one verb choice and improve one precise weakness.
Result: 0–2 Rebuild · 3–4 Developing · 5–6 C1 mastery evidence.
Score the first independent attempt across MEAN, FORM and USE. Give one target only: source ownership, stance strength, complement family, relationship or evidence limitation. Keep the original score and record the retry separately.
You can now attribute and connect several positions without distorting what each source meant. Use the Dynamic Learning Graph below to revisit viewpoint and evidence distance or continue to hedging and boosting claims.
