Assignment – Part B
A case study analysis using Toulmin’s Model of Argument (~600 WORDS)
Use the following Table provided for your answers as instructed.
1. You must use the case study provided in the Assignment Details Document.
2. You must analyse every sentence individually in the case study to establish whether it is a Toulmin element and each identified sentence should be individually included in the table below.

Part B of the assignment requires you to apply Toulmin’s Argument Model to analyse a case study to determine the validity or otherwise of the case study’s claim, again reference any additional information sources that you may use.

You MUST use these instructions to complete the ‘Your Opinion’ section of Part B:
Toapplythemodeltotestthevalidity/strengthofaCLAIMthereadermustexamineeach sentenceinthe article and categorise them as a Toulmin element or as an unnecessary extra
e.g.‘opinion’,‘hearsay’,‘definitions’etc.Onceallsentenceshavebeencategorisedthenthe elements should be examined in sequence.
1. What is the CLAIM?
2. Is there any EVIDENCE to support the CLAIM? If so how much and how does it affect the strength of the
CLAIM.
3. Is there a WARRANT (Explicit or Implicit)? Explicit WARRANTS are often stronger because the author can
direct the reader to accept the CLAIM. Implicit WARRANTS leave the reader’s opinion open to
interpretation and this may go against the author’s intended purpose.
4. Is there BACKING? If so how much? If so how much and how does it affect the strength of the CLAIM. 5. Is there a REBUTTAL? The quantity and scope of the REBUTTAL may reduce the strength of the CLAIM
and thus dissuade the reader’s acceptance of the CLAIM.
6. Is there a QUALIFIER? If so, to what extent does it reduce the scope of the CLAIM because this will
impact on the strength of the CLAIM?
7. Your Opinion – this is a personal perception based on your interpretation of the article. The presence,
quality and quantity of the different Toulmin elements must be applied to make this critical assessment. You must discuss whether you agree or disagree with the claim based on the stronger argument.
