To be Critical in university work means really thinking about what you’re reading, asking questions, not always believing everything you read (or hear) is true.
don’t just accept information or situations that are given to you
try to understand why they are the way they are
ask what other possibilities exist, and what you might be able to do about them
You are expected not simply to accept and repeat what you have read, but to make clear how valid you think it is in general, and how relevant it is to your own topic
When lecturers set an assignment beginning 'Discuss', 'Comment on', 'Assess'.., they are inviting you to be critical
Sometimes students misunderstand what being critical involves; it isn't just about being negative, but involves evaluating information fairly pointing out both strengths and weaknesses.
Critical reading - When reading, you need to ask questions about the text. This will keep you focused, and help you to develop an understanding of the text.
Evaluating arguments - When reading a text containing an argument, you need to evaluate whether the writer has supported their ideas sufficiently and whether you agree with them.
