Critical thinking is a mental process of questioning and evaluating what you read, hear, and see (Palgrave, n.d.). Being able to question or doubt ideas or arguments and not accept them at face value is part of the process. You will need to demonstrate the ability to think critically by:
This process involves:
You can use the learning cycle and the six questions (5W + 1H system) to trigger your critical thinking.
Think about the six questions: What, Who, When, Where, Why, and How, as demonstrated in the table below.
What are the main messages, arguments, results, or findings?
What type of source is it? e.g. a research study, professional opinion, discussion, website or other?
Who is the target audience?
Who has written, said or produced the source?
Is the author/speaker an organisation or an individual?
Are they an expert in the topic?
Could they have any bias?
How do you know?
When was it published or updated?
Check if recent work is available; older key information may still be valid.
Where did you find the information? Where was it published?
Did you find the information by chance? Or did you find it through a systematic search?
Why has this been written, said or produced?
What is the aim of the information?
Who is the information aimed at – professionals or patient/client groups?
How has the author/speaker come to their conclusions?
Is their line of reasoning logical and understandable?If it is research or a review of research, how was it carried out, was it done well and do the conclusions reflect the findings?

This is the learning cycle that can help you reflect on your learning process. In this cycle there are four stages, as summarised in the diagram below.
