Critical thinking is a process used to think about and evaluate information and reach a conclusion. Critical thinking is used when there is a question of problem solving, where you shouldn’t automatically accept that information as valid, true, applicable or correct. Instead, you should gather the evidence; analyze all aspects rationally and objectively, and with an open mind, so as to reach your own conclusion.

 How to do critical thinking and Evaluation:

Gather information:

• First gather all the data or information you have regarding to the problem.
• Research about it
• Write down key points
• What are the arguments?
• Are there any assumptions (things accepted as true without proof)?

 What will you do with information?

• Identify the problem that needs to be solved
• Make notes, write a rough draft of your thoughts
• Break down the problem/issue into parts and start with the first part.

 Analyze the information

• How do the bits fit together and relate to one another?
• Compare the various ideas: are there any similarities or differences?

 Evaluate the various views:

• What evidence is there for the various viewpoints?
• Which points are in agreement, which ones disagree?
• Make sure you consider all sides of the argument, especially those you disagree with.
• Are there logical connections between the various sources and ideas?
• Compare what you’ve found with your initial thinking about the topic. Do you still think the same way or have your views changed at all?
• Which of the ideas you’ve found are relevant to your needs?

 Construct the idea:

• Bring all the ideas together
• Are there more than one response?
• What will be the best solution?

 Use these ideas: 

• Construct an argument.
• Identify implications.
• Reach a logical conclusion.

 Apply your understanding:

• Answer the questions, and
• Write your assignment.
