Your critical evaluation checklist should include:
Identify what is important:
- key ideas, arguments, findings and conclusions
- Is the evidence reliable and valid or vague and obscure?
- Is the language appropriate or emotive and biased?
- Are the methods of investigation appropriate?
- Do you agree with the assumptions and inferences being made?
Evaluate publications against each other:
- What other perspectives and viewpoints have you discovered?
- Have you identified arguments and sub-arguments?
- Do you require more information from other sources?
Your own interpretation and summation:
- Have you personal observations to contribute?
- Are you able to connect ideas from the experts you have read?
- Is your analysis intelligent and objective
