Reichenbach: An Introduction to Critical Thinking
Critical thinking involves the use of a group of interconnected skills to analyze, creatively integrate, and evaluate what you read and hear. To become a critical thinker you must be able to decide whether an author�s opinions are true or false, whether he or she has adequately defended those ideas, whether certain recommendations are practical, as well as whether particular solutions will be effective.
Critical Thinking Dispositions
Critical thinking involves certain dispositions. A disposition is a tendency to act or think in a certain way. Review the list of dispositions that are characteristic of critical thinkers.
To learn how to think critically, one must learn skills that build upon each other. Only by concentrating on and practicing these basic skills can mastery of critical thinking be achieved. The author lists three basic characteristics of the skills required to think critically: they are interconnected (review a sample list of these skills), they build on each other, and they are goal-oriented in that we can constantly apply them to situations in everyday life.
- Characteristics of Critical Thinking
Critical thinking involves the use of a kind of thinking called reasoning, in which we construct and/or evaluate reasons to support beliefs. Critical thinking also involves reflection � the examination and evaluation of our own and others� thoughts and ideas. Finally critical thinking is practical. Actions are more rational if they are based on beliefs that we take to be justified. Critical thinking then, is the careful, deliberate determination of whether we should accept, reject or suspend judgement about the truth of a claim or a recommendation to act in a certain way.
Review what the guiding model of the text. This model is discussed in steps or stages. For each step note the specific headings to help you identify the level discussed.
Step 1: Knowledge
In terms of critical thinking, the basic level of acquisition of knowledge requires that you be able to identify what is being said: the topic, the issue, the thesis, and the main points. See Chapter Three.
Step 2: Comprehension
Comprehension means understanding the material read, heard or seen. In comprehending, you make the new knowledge that you have acquired your own by relating it to what you already know. The better you are involved with the information, the better you will comprehend it. As always, the primary test of whether you have comprehended something is whether you can put what you have read or heard into your own words. Review some key words that help you identify when comprehension is called for. Remember that comprehending something implies that you can go beyond merely parroting the material back but instead that you can give the material your own significance.
Step 3: Application
Application requires that you know what you have read, heard, or seen, that you comprehend it, and that you carry out some task to apply what you comprehend to an actual situation. Review the some tasks that require application.
Step 4: Analysis
Analysis involves breaking what you read or hear into its component parts, in order to make clear how the ideas are ordered, related, or connected to other ideas. Analysis deals with both form and content. Reviewhow critical thinkers analyze form. Reviewhow critical thinkers analyze content.
- Step 5: Synthesis
Synthesis involves the ability to put together the parts you analyzed with other information to create something original. Review some key words that help you identify when synthesis is called for.
Step 6: Evaluation
Evaluation occurs once we have understood and analyzed what is said or written and the reasons offered to support it. Then we can appraise this information in order to decide whether you can give or withhold belief, and whether or not to take a particular action. Review some key words that help you identify when synthesis is called for. Never put evaluation ahead of the other steps in critical thinking steps; otherwise, you will be guilty of a "rush to judgement." When emotion substitutes for reasons, evaluation incorrectly precedes analysis.

In order to thoroughly learn something, as opposed to memorizing and regurgitating the information (which is usually followed by promptly forgetting the information), one needs to have critical thinking skills. This means that you can articulate what it is you are studying, you are open to all possibilities of what you may discover, and that you can assess, review, understand, and draw your own conclusions based on what you have learned.
There are six steps to the critical thinking process. The first step involves demonstrating you have learned basic knowledge about the subject by being able to list and identify main components of the topic. Step two is understanding the topic. Can you summarize it in your own words? Can you explain it to someone who has no prior knowledge about the topic? The third step is applying the knowledge you demonstrated in steps one and two. Can you take that information and apply it to a different set of circumstances? Step four takes it to another level because you need to be able to analyze the information. One way to do this is to compare and contrast it. The fifth step involves not only breaking down the information, but being able to synthesize it with what you already know. Can you combine it with prior knowledge to create something new? Finally, the sixth and final step asks you to evaluate, explain, and assess the information to come up with your own conclusions.
Critical thinking is a skill that will allow you to take studying to a whole new level. Instead of accepting information at face value, critical thinking allows you to discover, question, formulate new ideas, and reach your own conclusions.
