Critical thinking is essential to seeking a deep and rigorous understanding of our challenges, but it happens to elude us when we need it most. Common but problematic problems can only be solved through critical thinking, as illustrated in the course work. From the course, the three lessons that are significant to me are: replacing and changing barriers that stop the critical thinking process, the five-step problem-solving process, and determining the trustworthiness and credibility of a message and source.

Get an Original EssayReplacing and Changing BarriersExternal barriers such as family, friends, teachers, and media can be replaced using the self-directed method or the social-direct method. Self-directed substitution is initiated by an individual; you intentionally decide to escape the barriers. Society-directed replacement is initiated by social movements that change the way we think (Ridel, 2015 p. 56). Internal barriers such as rationalization, emotions, stubbornness and prejudices can be modified to minimize their impact on our critical thinking. Each of the four internal barriers can be adjusted separately to benefit individuals who aspire to be critical thinkers. Replacing and modifying barriers to critical thinking are useful in everyday life as individuals learn how to deal with difficult situations that tend to inhibit their critical thinking. Replacing and changing barriers as a subtopic of the course is significant as it provides a solution to barriers in critical thinking. The Five-Step Troubleshooting Process In the course, the five-step troubleshooting process is clearly explained. First you need to identify a problem; otherwise it would be useless to try to solve the problem. When facing a problem, you need to pay close attention to defining the problem before finding the solution. Second, the course identifies discovering the cause of the problem as the next step. The step is significant because a problem cannot be solved without understanding its cause. The third step is to create options to solve the problem. It is at this stage that creative thinking is also used. The fourth stage of the process involves evaluating the best options for solving the problem. As highlighted, the course is significant in enabling students to distinguish between creative thinking and critical thinking. Step four of the process explains the need to think critically when evaluating options after creative thinking. Finally, take action, monitor and modify the options selected in the final step. The course is significant in the final phase as students are informed of the sub-steps necessary for the best solution to a problem. In everyday life, the course is significant because we acquire the knowledge necessary for an organized problem-solving process (Ridel, 2015, p. 137). Please note: this is just an example.
