This unit develops the ability to analyse, evaluate and develop facts, ideas and opinions. You will learn to identify claims, reasons and evidence, follow an argument, recognise assumptions and bias, compare viewpoints, select relevant textual support and make justified judgements.

1. Fact, Opinion and Interpretation

A fact is information that can be checked or verified. An opinion expresses a belief or judgement. An interpretation explains what information may mean.

Example

Fact: “The library opened at 8 a.m.”

Opinion: “The library opens far too late.”

Interpretation: “The early opening suggests that the school wants students to use the library before lessons.”

2. Identifying the Writer's Main Ideas

The main idea is the central point the writer wants the reader to understand. Look for important claims, repeated concerns, topic sentences, explanations and conclusions.

3. Supporting Ideas

Writers develop main ideas through reasons, examples, facts, explanations, comparisons, statistics, expert views and consequences. Identify how each supporting detail contributes to the larger idea.

4. Separating Assertion from Evidence

An assertion is a claim made by the writer. Evidence is information used to support that claim.

Example

Assertion: “The new cycle route has made commuting safer.”

Evidence: Accident records or carefully collected observations could support the claim.

5. Analysing How an Idea Is Developed

An idea may be introduced, explained, supported, extended or qualified. Follow its development from paragraph to paragraph.

Development pattern

Claim → reason → evidence → explanation → consequence → conclusion

6. Following an Argument Through a Passage

An argument is a connected line of reasoning. Identify the writer's position, the reasons supporting it, the evidence supplied and the conclusion reached.

  1. What does the writer claim?
  2. Why does the writer believe it?
  3. What evidence is supplied?
  4. How does the evidence support the claim?
  5. What conclusion follows?

7. Reasons and Supporting Evidence

A reason explains why a writer holds a position. Evidence provides support for that reason or claim.

ElementQuestion to ask
ClaimWhat is the writer saying?
ReasonWhy does the writer say it?
EvidenceWhat supports the claim?
ExplanationHow does the support connect to the claim?

8. Evaluating Whether Evidence Is Convincing

Consider evidence for its relevance, sufficiency and reliability. Ask whether it genuinely supports the claim.

9. Evaluating the Strength of an Argument

A strong argument connects claims, reasons and evidence clearly. It avoids major contradictions and draws conclusions supported by the available information.

Do not call an argument strong simply because you agree with it.

10. Recognising Assumptions

An assumption is something treated as true without being fully established. Critical readers identify what the writer appears to take for granted.

Example

“Everyone wants a longer school day.” This assumes that all students, teachers and families share the same preference.

11. Recognising Bias and Perspective

Perspective is the position from which a writer views an issue. Bias occurs when presentation favours one side unfairly or selectively. Look for selective evidence, loaded wording, omission of important alternatives and unequal treatment of opposing views.

12. Distinguishing Strong and Weak Reasoning

Stronger reasoningWeaker reasoning
Connects evidence to the claim.States a claim without support.
Recognises relevant limitations.Ignores obvious limitations.
Uses relevant evidence.Uses irrelevant examples.
Draws a proportionate conclusion.Jumps from limited evidence to a sweeping conclusion.

13. Comparing Viewpoints

When two writers discuss the same issue, compare their claims, reasons, evidence, assumptions, perspectives and conclusions.

Useful frame

Both writers agree that ______. However, Writer A emphasises ______, whereas Writer B focuses on ______.

14. Selecting Relevant Textual Evidence

Good analysis uses evidence that directly supports the point being made. Choose the smallest relevant piece of information that proves or illustrates the point, then explain its significance.

Evidence rule

Point → Evidence → Explanation

15. Explaining Why Evidence Supports an Idea

Do not stop after identifying evidence. Explain the connection. Ask: What does this evidence show, and why does that matter?

16. Making a Justified Judgement

A judgement is strongest when it is based on relevant evidence and reasoning. Explain why your conclusion follows from the information in the text.

17. Avoiding Unsupported Personal Opinions

Personal response is not the same as textual evaluation. Your judgement should be connected to the text rather than based only on whether you agree.

18. Cambridge-Style R3 Answer Construction

Recommended structure

Identify the claim → select relevant support → explain the connection → evaluate → reach a justified judgement.

19. Worked Example

Claim: A writer argues that a community garden benefits local residents.

Evidence: Residents use the garden for exercise, social interaction and growing food.

Analysis: The range of benefits supports the claim because the evidence shows that the garden serves more than one practical purpose.

Evaluation: The argument is reasonably convincing, although reliable figures about how many residents benefit would make it stronger.

20. Differentiated Practice

Foundation: identify fact, opinion, claim and evidence.

Developing: explain how supporting details develop a main idea.

Secure: evaluate whether evidence convincingly supports a claim.

Advanced: compare two viewpoints and reach a justified judgement.

21. Assessment Criteria

LevelEvidence of performance
MasteryAnalyses and evaluates ideas precisely, selects relevant support, explains connections and reaches justified judgements.
SecureIdentifies important ideas and uses relevant support with generally clear explanation.
DevelopingIdentifies some ideas or evidence but explanation and evaluation may be incomplete.
Not yet secureRelies mainly on description, unsupported opinion or disconnected details.

22. Full Original Practice Passage

Original passage

“The town council should convert the unused car park beside the river into a public reading garden. The site already attracts walkers, but it has no quiet place where they can sit. A reading garden would provide shaded seating and could encourage families to spend more time outdoors. Some residents argue that the car park should remain available for visitors arriving by car. However, the council's own survey shows that the car park is rarely more than half full on weekdays. This suggests that part of the space could be redesigned without removing essential parking. The proposal is therefore a practical compromise rather than an attempt to eliminate car access.”

23. Analyse the Passage

  1. Identify the writer's main claim.
  2. Identify two supporting ideas.
  3. Find one piece of evidence.
  4. Identify the opposing viewpoint.
  5. Explain how the survey evidence supports the writer's position.
  6. Identify one assumption the writer makes.
  7. Evaluate how convincing the argument is.

24. Mastery Checklist

25. Cambridge-Style Transfer Task

When answering an R3-style question, do not simply copy information from the passage. Select, connect, explain and evaluate.

Exam habit

Point → relevant evidence → explanation → evaluation → judgement.

26. Course Progression

This unit completes the current sequence on understanding and evaluating ideas. It connects close reading with the next examination stages: selecting information, summarising, comparing material and responding accurately to specific purposes.

Progression

Understand → Infer → Analyse language → Analyse and evaluate ideas → Select and use information
