Critical Thinking: Identifying Assumptions

Active learning helps students grasp abstract concepts like identifying assumptions by making them visible in familiar contexts. When students analyse real-world examples such as advertisements or debates, they connect theory to practice, which builds deeper understanding and retention of critical thinking skills.

Pair Analysis: Everyday Adverts

Pairs receive print adverts or social media claims. They list the conclusion, then hunt for hidden assumptions, such as 'This product works because celebrities use it'. Pairs share one finding with the class and justify it. Conclude with a vote on strongest examples.

Analyze methods for identifying hidden assumptions within an argument.

Facilitation Tip

During Pair Analysis: Everyday Adverts, pair students with contrasting perspectives to encourage richer discussions about cultural assumptions in advertising.

What to look for

Present students with a common advertising slogan (e.g., 'Buy this product for happiness'). In small groups, ask them: 'What assumptions does this slogan make about happiness? What assumptions does it make about the consumer? List at least two assumptions and discuss why they might be problematic.'

Small Group Debate: Assumption Challenges

Form groups of four with a debatable statement like 'Homework always improves learning'. Each group identifies assumptions in the statement and counters with alternatives. Groups present to class, fielding questions on overlooked premises.

Evaluate the impact of unexamined assumptions on reasoning.

Facilitation Tip

In Small Group Debate: Assumption Challenges, assign roles like 'assumption detective' to ensure every student actively participates in spotting hidden premises.

What to look for

Provide students with a short, simple argument. Ask them to write down the conclusion and then list two unstated assumptions that are necessary for the argument to hold. Collect these to gauge understanding of identifying implicit premises.

Whole Class Socratic Circle: Doubt in Action

Students sit in two circles; inner circle discusses a philosophical claim while outer notes assumptions. Rotate roles midway. Teacher prompts with questions like 'What must be true for this to hold?' to guide identification.

Explain the function of doubt in the philosophical search for truth.

Facilitation Tip

For Whole Class Socratic Circle: Doubt in Action, model sceptical questioning yourself first to set a tone of respectful inquiry rather than confrontation.

What to look for

Students write a brief paragraph expressing an opinion on a current social issue. They then exchange paragraphs with a partner. Each student identifies one assumption their partner made and writes a sentence explaining why it's an assumption. Partners then discuss their findings.

Individual Reflection: Personal Beliefs Journal

Students write a personal belief, e.g., 'Social media harms youth'. They then list three hidden assumptions and revise the belief. Share anonymously via slips for class analysis.

Analyze methods for identifying hidden assumptions within an argument.

Facilitation Tip

During Individual Reflection: Personal Beliefs Journal, provide sentence starters like 'I assumed... because...' to structure their thinking.

What to look for

Present students with a common advertising slogan (e.g., 'Buy this product for happiness'). In small groups, ask them: 'What assumptions does this slogan make about happiness? What assumptions does it make about the consumer? List at least two assumptions and discuss why they might be problematic.'

A few notes on teaching this unit

Teachers should introduce this topic by first normalising assumptions as natural in arguments, not as flaws to immediately reject. Use Indian examples like political speeches or Bollywood movie plots to ground the concept in students' lived experiences. Avoid rushing to 'correct' assumptions prematurely—instead, guide students to test them through evidence and dialogue.

Students will confidently identify unstated premises in arguments and explain their significance. They will demonstrate this by discussing assumptions in groups, rebuilding flawed logic, and reflecting on their own biases, showing growth from initial confusion to nuanced analysis.

Watch Out for These Misconceptions

• During Pair Analysis: Everyday Adverts, students may dismiss assumptions outright as 'wrong' or 'bad'.

  Redirect them to evaluate the strength of assumptions using evidence, such as asking 'Does this assumption hold up under scrutiny? What proof supports it?'.

• During Small Group Debate: Assumption Challenges, students might think identifying an assumption means the argument is automatically invalid.

  Use the debate to rebuild arguments by replacing weak assumptions with stronger ones, showing that assumptions are tools to refine reasoning.

• During Whole Class Socratic Circle: Doubt in Action, students may believe arguments without stated reasons have no assumptions.

  Prompt them to ask 'What must be true for this to make sense?' to uncover implicit premises in simple claims.
