As a student, one of the best ways to think critically is to take the time to really consider and analyze the material you are presented with.
Ask yourself questions, such as why this material is relevant to what you are studying, what the implications are, or what the deeper meaning behind it is.
Doing research and expanding your knowledge base can also help you develop your critical thinking skills.
Taking notes and summarizing the information you are presented with can also help you learn to think critically as you are forced to synthesize the material into a concise and meaningful format.
Finally, engaging in meaningful discussions with your peers and instructors can help you think critically as you are exposed to different perspectives and ideas.
