This module teaches you to take an argument apart: what is being claimed, which reasons are offered, and whether the evidence really supports them. These skills sit under every research task in Global Perspectives (syllabus code 0457), because every source you read is making claims of some kind.
The examples here are original and low-stakes. Any source, school or survey named in the lessons is invented and labelled as such, so you can practise judging the argument without needing an opinion on a real controversy.
What do you need before you start?
You should already be comfortable asking who wrote a source and why, as covered in sources and credibility. You also need basic comfort with fractions and percentages of small samples, such as 6 out of 8 being 75%.
No outside knowledge of any country or issue is needed. The lessons give you everything required to judge the argument.
An orienting example
Here is a short invented text. A student blog (invented) says: “Our school should add water refill stations. Students buy a lot of bottled water, and a bin audit last week found 90 plastic bottles on one afternoon.”
Sort it into parts:
- Claim: the school should add water refill stations.
- Reason: students buy a lot of bottled water.
- Evidence: a bin audit found 90 plastic bottles on one afternoon.
Now test the link.
The 90 bottles show that bottles are being thrown away. They do not show how many students produced them, or whether refill stations would change anyone’s habits. The evidence supports a smaller statement than the claim, and that gap is where the rest of this module works.
In what order should you study the lessons?
- Distinguish a claim from a supporting reason: start here, because every later skill needs you to name the parts correctly.
- Explain whether cited evidence actually supports a statement: this checks the link between a reason and its evidence.
- Identify an assumption in an original non-political argument: this finds the unstated step that makes the argument work.
- Revise an overgeneralised conclusion to fit its evidence: this turns your criticism into a corrected, fairer statement.
Finish with the integrated practice set, which mixes all four skills.
What are the common traps?
- Treating a reason as a claim. A reason is meant to support something else; if you find yourself asking “why?”, you are probably looking at a claim.
- Judging a source’s confidence instead of its support. A confident tone is not evidence.
- Marking a statement “wrong” when it is only “not shown”. The evidence may be accurate and still not reach the conclusion.
- Hunting for assumptions that are really just facts. An assumption is a step the author needs but does not state.
- Fixing an overgeneralised conclusion by deleting it. A better answer keeps what the evidence does show and narrows the rest.
How should you use the practice set?
Attempt each question on paper before opening the answer, and write your sorting of claim, reason and evidence first. The questions run from easier to harder, so a miss early on usually points to lesson one, while a miss on later questions points to the lesson named in the answer.
The skills in this module are the base for the next topics, such as data interpretation and limitations and comparing perspectives. A student who can name a claim and test its support will find both much easier.
A teacher working with you can use your own research notes to show where a claim and its evidence drift apart, without writing any assessed work for you. That is the focus of our online one-to-one Global Perspectives tuition.
