Remember assess means:

“Give careful consideration to all the factors or events that apply and identify which are the most important or relevant. Make a judgement on the importance of something, and come to a conclusion where needed”

Think:

• What are the key features of a case study?
• How would Dr Cottick actually set about doing his case study?
• What are the strengths and weaknesses of this research method and how do they app, to Dr Cottick’s research?
• What other research methods could be used to investigate the effectiveness of Dr Cottick’s intervention?
• How would this other research method compare with the use of the case study?
