Critical Thinking


Critical thinking has been very much discussed in education, and there are many definitions of it available. These definitions can change, depending on discipline or culture. But definitions do agree that critical thinking involves careful, skeptical, and conscious thinking; in Western academic circles, it is the sort of thinking guided by logic and method that academics value. Critical thinking includes the ability to view any object of study from multiple perspectives and to recognize the cultural, ideological, and cognitive frames (or schemata) we bring to understanding.

Encourage Critical Thinking in Written Work and Speeches

You probably hope they will research 15 sources and use 5. But too often they stop research when they reach the magic number. Instead, tell them to include a “Works Consulted” page in their paper that will demonstrate their research process to you. The works they actually cite can be included in a “References” or "Works Cited” page.
This is the ideal time to discuss your own research/writing process. Explain how writing about a topic, from taking notes to communicating results, helps you deepen and organize your thinking.
For example, have a class discussion about possible approaches to the problem the assignment addresses, or ask students to throw out ideas developing the topic they might write about, and discuss them for all the class to hear. Or, a few days after you make the assignment, ask students to come to class with three possible topics, and have them discuss them in small groups to help them select and develop one. For more ideas, see Developing Content.
There are many ways to do this, but here is one: Ask them to write a mini-essay or present a two-minute, impromptu speech (in-class, no grade) about what they are discovering. After class, select the best two or three essays, and bring them to the next class to read aloud and discuss—what made them the best and what directions can you suggest to the author for further research or development of the idea? For the two-minute speeches, take notes and give a few comments at the end of the best performances. 

Whatever the activity, the goal is to make communication an integral part of the way students learn—they are writing to improve their knowledge and understanding of your course content, not merely to repeat ideas you have poured into them. When they write, they take what you teach and make it their own, and that, in essence, is critical thinking.

Critical thinking is a habit and a skill, something which, like the composing process, many of our students may have to learn and practice. Putting words on paper or preparing to address an audience helps students slow down and consider an issue in greater depth. It also demands that they express their views or opinions at some level. Even a plain explanation or review of the "facts" requires students select pertinent facts, organize them in a rhetorically effective way, and present them accurately.

These skills are frequently viewed developmentally, usually according to Bloom's taxonomy, as follows:

To promote critical thinking skills more fully, ask students to make an argument, take a stand, or defend a thesis. To do so in a responsible way for an academic or educated reader requires that they consider the following:

While every assignment cannot necessarily ask students to present a full-fledged argument, every assignment can expect students to present and defend a thesis in a reasonable and logical manner.

To up the level of critical thinking even more, ask that students go beyond defense of a thesis. Encourage students to find creative solutions to problems and make defensible value judgments. Use case study assignments or challenge students to discover problems themselves. Ask for a critical analysis and proposed solutions. In short, ask for synthesis and evaluation.

The Critical Thinking Resource Guide, developed at Washington State University in 1999-2000, is an excellent tool for creating assignments and evaluating critical thinking skills. Students often express concern about expressing their own ideas. They may worry that disagreement with a professor will lower their grade, or they may believe that opinion, along with the first-person "I," has no place in college writing. Show them that you do value their views, and that you will read with an open mind if they argue well.
