Critical thinking is an essential skill for researchers. Without critical thinking , your literature review will be just a summary of what others have said. Critical thinking enables you to evaluate the evidence of reported findings, and the opinions of experts. It enables you to gather information and assess its relevance to a question. It enables you to explore other points of view and form your own ideas. And it also enables you to consider the implications of findings and integrate these in your evaluation.
In this video from the University of Technology, Sydney, David Sotir discusses how to apply critical thinking skills to writing and research.
