Making Critical Thinking Possible: Options for TeachersIan Wright
To develop a curriculum for the teaching of critical thinking in the Social Studies, 1 it is first necessary to determine how critical thinking is to be conceptualized.
If critical thinking is defined as a set of generalizable skills, then it is assumed that any subject matter within or beyond the boundaries of social studies can act as a vehicle, and whatever is learned can be transferred to other subject areas. 2
If, on the other hand, critical thinking differs according to the subject (and there is much debate about what "subject" means [Norris 1992]), then critical thinking has to be taught in each of the subjects (history, geography, economics, etc.), and there is no transfer of what is learned in one subject to another.
A third view is that while some critical thinking components are transferable, not all of them are. If this view is correct, then the question of which are and which are not is vital in determining how critical thinking is to be taught.
Even when we have decided which view is the most defensible, we will still have to decide what to teach, as all of the extant conceptions include a variety of standards, heuristics, skills, and dispositions (i.e., Ennis 1991; Lipman et al. 1980; Siegel 1988; Paul 1990; Baillin et al. 1993; and McPeck 1990). They cannot all be developed in a single course or grade level; choices have to made, sequences decided upon, and teaching methodologies determined.
The three options presented here for teaching critical thinking allow teachers to select a strategy that corresponds to their conceptual assumptions. They consist of a critical thinking module, an infusion approach, and a strategy combining the module and an infusion approach.
A Critical Thinking Module
One obvious way to focus on critical thinking within the social studies is to teach a separate module, either using an existing program like Philosophy for Children's Mark (Lipman 1979), which deals with the philosophy of the social sciences, or designing new materials. What might be envisioned here is a module designed to help students deal critically with the mass media, major political issues, or such topics as historiography or informal logic using examples drawn from the Social Studies curriculum.
There are both advantages and disadvantages to this approach.
Using an existing program has the advantage that it is immediately available and has been created by experts. In the case of the Philosophy for Children program, these experts provide in-service training and support groups. A further advantage is that a teacher can "learn by doing." By teaching the program, he or she will learn about critical thinking; the materials provide instruction for both teachers and students.
A separate module can deal with the really important social problems that do not always appear in the existing social studies curriculum, even though they are clearly part of social studies. As Paul (1990) points out, significant issues are not generally found within the boundaries of one discipline such as history or geography. They tend to be multi-logical-which political party to vote for, what to do about drug use, how to prevent violence in the school, and so on.
A further advantage to the separate module approach is that it may foster a more critical attitude because it is specifically designed to encourage critical thinking, rather than assisting in learning particular social studies content. And if the issues studied are significant in everyday life, then there is a greater likelihood of transfer. For example, the student who learns how to critique advertising may well also learn how to deal with political messages, calls to join particular organizations, and persuasive sales persons. Thus, the separate module approach has a number of advantages. If, unlike Mark, it is designed by teachers, it is more likely to fit the constraints and opportunities of the existing social studies curriculum and the contexts in which it is taught.
A possible disadvantage arises from using existing critical thinking/social studies programs or creating a separate critical thinking/social studies module: there is the risk that what is learned in the module will not be transferred to the rest of the social studies curriculum. This has been seen as a major stumbling block when critical thinking is taught as a distinct course (Kennedy, Fisher, and Ennis 1991; Sternberg 1987). It can be avoided only if there is a concerted effort by teachers to use and build upon what was learned in the critical thinking module (Ruggiero 1988). Thus, what is taught in a separate module has to be coordinated with the rest of the social studies curriculum. Another disadvantage of having a separate critical thinking module may be that it will require a slot in the curriculum at a time when the existing social studies curriculum is already perceived to be overloaded.
Another approach favored by some is infusion, in which critical thinking is incorporated into the existing subject matter in a number of different ways. O'Reilly systematically infuses critical thinking in his history materials (1985). Paul et al. (1987/1989) have restructured existing lesson plans in social studies (as well as in other subject areas) to incorporate critical thinking, while Beyer (1987, 1991) focuses on particular skills and uses the social studies content as a vehicle to teach them.
Another way of infusing critical thinking into the social studies curriculum is to base the teaching of it on a procedure such as problem solving (Quellmalz 1987). This involves identifying key problems in the social studies curriculum and using relevant aspects of critical thinking to clarify the problem, assess evidence, judge solutions, and so on. Ruggerio (1988) suggests a model of problem solving with five steps, the last one focusing specifically on critical thinking: Exploration (that a problem exists), Expression (stating what the problem is), Investigation, Idea Production (producing possible answers), and Evaluation and Refinement (ascertaining whether the answer is reasonable). With similar objectives, Schiever proposes the use of Taba's curriculum principles and the application of aspects of critical thinking to concept development, data interpretation, application of generalizations, and resolution of conflicts (1991).
Using these models and guides allows students to be exposed to critical thinking competencies within the curriculum content. It may be seen as an integrated part of learning the content-there is less risk of teaching "inert" knowledge of the kind that is never applied outside of the subject matter (Sternberg 1987). Further, there are some excellent materials available that do not require the creation of a separate timetable slot (see Kruse 1989; Chance 1986; Coles and Robinson 1989; and Idol, Jones, and Mayer 1991).
The disadvantages of the infusion method are that the teaching of critical thinking may lack any sensible sequence or coherence-a little informal fallacy recognition here, a little concept analysis there, etc. While the separate course approach requires teachers who are well versed in critical thinking, it does not necessarily require that all teachers in a school be experts. The infusion approach requires all teachers to be well versed in, and disposed toward, critical thinking, 3 but there are some indications that these are lacking in some teachers (Wright 1991; Onosko 1989; McKee 1988).
Coordination between teachers of different social studies courses is necessary for the basics of critical thinking to be covered in some intelligent way. Beyer (1991) argues that the teaching of critical thinking must be coordinated because
(1) Each teacher needs to know what others are doing.
(2) No teacher can teach everything that is necessary. In fact, some aspects of critical thinking have to be taught in some social studies courses rather than others, and some components of critical thinking (such as dispositions) need to be fostered in all courses (which need to be coordinated).
(3) Skills need to be sequenced.
(4) All teachers need to know the full array of critical thinking competencies and habits of mind, so that they can decide which ones are most relevant to their courses.
Ruggiero's argument that critical thinking should be taught across all subjects because of the need to practice a particular skill in a variety of contexts applies to social studies (Ruggiero 1988). He views the teaching of critical thinking to be akin to the teaching of writing-it must be done across the curriculum (and thus in all social studies courses). Olson and Babu make the point that the vocabulary of critical thinking ("argument," "assumption," the use of logical operators such as "therefore") has to be taught, and that this needs to be infused in all courses (1992). All this will take commitment and time. The latter is often lacking, given the increased role responsibilities of teachers and administrators.
Combined Module and Infusion Methods
A third approach is to combine the single module and infusion methods in an attempt to realize the benefits of both. This allows a serious and systematic focus on critical thinking both in a module devoted to it and in other social studies courses. Transfer is (theoretically) guaranteed. Because experts could teach the separate module, this would benefit teachers not knowledgeable enough to teach it, as well as students.
Sternberg recommends a mixed model in which there are one or more separate modules in critical thinking, and it is infused into the rest of the social studies curriculum (1987). Because there is too much in critical thinking for any one teacher to teach, this approach can expose students to a wide variety of critical thinking standards and heuristics. It also allows teachers to teach to their strengths while being cognizant of what other teachers are doing. With this approach, programs designed by experts can be used alongside locally designed ones that would be best suited to local conditions. Whatever approach is taken will require clarity about purposes; thinking about critical thinking in terms of K-12, not just in one grade level; and taking into account the politics of the school and the community.
This still leaves us with the question of what is to be taught. Should we teach students what an argument is, what informal fallacies are, what the standards are for a reliable observation claim, how to recognize assumptions, or all of these?
It seems to me that the crucial questions for a critical thinking program are "What is true, or plausible in this case?" and "What is a justifiable action in this case?" While commonplace, they are also profound-Is what this advertisement is claiming true? Did X commit the alleged crime? Did this student tell the truth when he said Y? Should I buy a new car or use the bus more often? Should we send more troops to the world's areas of conflict? How should I treat this "problem" student in my class?
We deal with these sorts of questions all the time yet we do not often help students deal with them; we continue to fill their heads with "truths" without questioning these, or even telling students why these might be believable. Yet it is possible for students to focus on truth and to learn some of the standards pertaining to it in various branches of knowledge. O'Reilly (1985) has shown this with his materials while Lipman et al. (1980) and Pritchard (1985) have demonstrated that even elementary students can learn quite sophisticated concepts and principles.
What should be done? In my view, students in social studies should learn the rules of evidence and should begin this process in the elementary grades (Pritchard 1985). They should learn the criteria for judging the reliability of observation claims (Norris and King 1985) and apply these in a variety of situations-when stating what they saw in a particular event, when judging the reliability of claims by a witness to a historical or contemporary event, or when determining how much pollution there is in a river. Students should also begin to grapple with some of the problems surrounding authority/expert claims. To be able to apply all of the criteria for judging the reliability of claims made by an expert (see Ennis 1969) requires a great deal of background information, but a start can be made (Blair 1992). For example, students should learn that a dentist is a better judge (usually) of teeth care than is a movie star advertising a particular brand of tooth paste. They should learn that newspaper reports are biased and that some reports lack objectivity and fair-mindedness. They should learn about conflicts of interest through everyday examples-e.g., telling a teacher what happened in a fight that involved a best friend.
Students should also understand the difference between supporting a claim on the basis of a single piece of evidence and on that of many pieces. Missimer describes a situation in which one of her students claimed that by chanting a mantra, he got what he wanted. His "proof" was that he had found a parking space on a busy street by chanting his mantra. Missimer gave him the job of logging multiple observations of a similar sort. She claims that on the basis of the experiment, the student has given up his belief (1990, 3).
Missimer teaches the standards pertaining to three forms of evidence-speculative evidence, correlation, and evidence from a controlled experiment. Again, students should learn that a correlation does not necessarily show a causal connection, that there are rules for conducting experiments, and that one person's speculative theory can be diametrically opposed to someone else's (Missimer 1990, 4). Thus, standards for truth can be taught and, as Siegel (1993) points out, need to be taught so that students are given some guidance as to how to adjudicate between competing claims and not to descend into an untenable relativism.
A second crucial question involves reasoning about what we or others ought to do. This puts us squarely into the realm of moral education. If one takes the view that education is a moral enterprise (Goodlad et al. 1990; Strike and Soltis 1985), and that critical thinking includes reasoning about moral questions (Weinstein 1988; Coombs 1989; Paul 1990; Wright and La Bar 1987), then one should not avoid raising moral questions in the classroom or treating them as matters that are not amenable to critical thought. The question is (as with empirical matters), are there any standards for truth in matters of moral values? Here, there is not time or space to go into all the arguments for the justifiability of particular moral standards. There is, however, a body of literature that deals with how students can go about dealing rationally with personal and social issues (Shaver and Larkin 1973; Evans 1982; Lipman 1976) and with why certain moral standards are defensible (Coombs 1971 and 1989). To indicate what, in my view, should be taught here, let me outline briefly the approach adopted in materials produced by the Association for Values Education and Research at the University of British Columbia (AVER 1978-1991).
In the AVER approach, first of all, an issue is clarified, alternative positions identified, and evidence collected and evaluated. Students then create arguments for their positions and determine the principles on which their arguments are based. This is essential because, on the basis of particular social/political principles, basic goods (survival, liberty, health, rights, etc.) are distributed in certain ways. As different people put emphasis on different basic goods, distribution of them is likely to be a disadvantage to certain people and an advantage to others. If distribution cannot be absolutely equal (and this, in certain circumstances, might be most unfair [Rawls 1971]), then what principles should be used and how could they be justified?
To justify a course of action, reasoners must identify the principle(s) on which their reasoning is based. Suppose, for example, someone argues that capital punishment is justified because it acts as a deterrent. In this case, the principle appealed to is, "What acts as a deterrent is justified." The next, and crucial, step is to have students justify their principles by applying the following "tests." 4
1. The Role-Exchange test requires reasoners to imagine themselves in the position of the person most adversely affected by the application of the judgment. If they cannot accept the judgment when viewed from this position, then it is not impartial.
2. The New Cases test requires reasoners to consider the application of the judgment to similar situations. If reasoners cannot accept these judgments, then the judgment is not consistent.
3. The Universal Consequences test requires reasoners to determine whether everyone who might want to act in the way condoned by the judgment could do so without producing consequences that would be unacceptable to the reasoners. If these are not acceptable, then the judgment is not universalizable.
4. The Subsumption Test requires reasoners to determine whether the judgment follows logically from their more fundamental ethical beliefs.
These tests cannot "prove" that one's judgment is correct. However, if a judgment "passes" the relevant tests, then the reasoner can have some confidence in its ethical acceptability; the judgment will be both impartial and consistent.
In both of these areas-epistemological and ethical-there should be a focus on the dispositions necessary for good critical thinking, on the knowledge necessary to think critically about the subject matter, the heuristics for arriving at reasonable conclusions, and especially the standards of critical thought (Baillin et al. 1993).
The program outlined is flexible. It could cover content already in the curriculum, or it could focus on new and relevant issues. It could be taught by a specialist who could help other teachers build on what is done in the critical thinking course. The specialist could teach all of the critical thinking modules to all students (if the school is small enough and the time tabling could be so arranged) and could act as in-service leader to the other social studies teachers.
By focusing on the two major questions of empirical truth and moral justifiability, the relevant components of critical thinking (heuristics, dispositions, the recognition of informal fallacies, and so on) can be applied to the content being examined. This might mean that different schools focused on different components at different times, but all would be emphasizing the same sorts of fundamental standards. If an already produced critical thinking program at a certain grade level was used, then all students would cover the same "content."
There is a burgeoning literature in critical thinking, and there are many opportunities for teachers to learn about it. But teaching critical thinking in the social studies needs careful thought. This proposal builds on the evidence and thoughtfulness of many people. It requires evaluation at both the theoretical and practical levels.
1. My article is premised on the assumption that the only subject with a critical thinking focus is social studies. I do not discuss situations where there are existing critical thinking courses in the school, or where critical thinking is incorporated in other subject areas, even though this would be the ideal I would want to attain. Further, it is assumed that critical thinking is a goal of education (see Siegel 1988, and McPeck 1981), and that the standards of critical thinking can be used to attempt to adjudicate between competing claims and arguments. It is thus assumed here that certain forms of postmodernism must be rejected (see Hatcher 1991; Siegel 1993).References

2. There are a variety of programs that appear to be based on this idea, e.g., Risby (1987) and de Bono (1990).
3. In this regard, there is what Friedman (1989) calls the "hemlock problem"-the opposition of teachers to any questioning of "authority."4. For a justification of impartiality and universalizability on which the "tests" are based, see Baier (1978), Perry (1976), and Coombs (1971).

The "moving wall" represents the time period between the last issue available in JSTOR and the most recently published issue of a journal. Moving walls are generally represented in years. In rare instances, a publisher has elected to have a "zero" moving wall, so their current issues are available in JSTOR shortly after publication.
Note: In calculating the moving wall, the current year is not counted.
For example, if the current year is 2008 and a journal has a 5 year moving wall, articles from the year 2002 are available.
