What is critical thinking?

What does it mean to think critically? What does thinkingmean at all?

What do the quotations reveal about critical thinking?

Reading furnishes the mind only with materials of knowledge; it is

thinking that makes what we read ours.

John Locke

Judge a man by his questions rather than by his answers.

Voltaire

Five percent of the people think;

ten percent of the people think they think;

and the other eighty-five percent would rather die than think.Thomas Edison

Cogito ergo sum.(I think, therefore I am.)

Ren Descartes

Science is a way of thinking much more than it is a body of knowledge.

Carl Sagan

Thinking is the hardest work there is, which is probably the reason so few

engage in it.

Henry Ford

Learning without thought is labor lost; thought without learning is

perilous.

Confucius

But if thought is to become the possession of many, not the privilege of

the few, we must have done with fear. It is fear that holds men back

fear lest their cherished beliefs should prove delusions, fear lest the

institutions by which they live should prove harmful, fear lest they

themselves should prove less worthy of respect than they have supposed

themselves to be.

Bertrand Russell

There are many definitions of critical thinking among researchers. This is because criticalthinking has its roots in philosophy and psychology. In recent times, universities have given

emphasis to critical thinking as a generic skill that is central to many, if not all, subjects.

Historically, the teaching of critical thinking was based on what is sometimes called the

philosophical approach. This approach focuses on the qualities and characteristics of the person,emphasising application and training in the rules of deductive logic, fallacies, reliable inference-making relying on statistics and research methods, and so on. On the other hand, the cognitive

psychology approach is framed in terms of cognitive skills, and focuses on the mental processes

involved in thinking.

Both the philosophical and cognitive psychological approaches enumerate a list of desirable

attributes, the former a list of perhaps idealised standards such as "reflective scepticism"

(McPeck, 1981) and the latter a list of actions and behaviours expected of critical thinkers, which

is more process oriented and procedural in nature.

Those working in the field of education have also participated in discussions about thinking. Theeducational taxonomy approach arose from classroom practice and is associated with BenjaminBloom (1956). The taxonomy for information processing skills is one of the most widely cited

sources for educational practitioners when it comes to teaching and assessing higher-order

thinking skills. Blooms taxonomy is hierarchical, the assumption being each level has to bemastered before one can progress to the next.

Read the following excerpts on what critical thinking is:

1. Discussions of critical thinking owe much to definitions devised by philosophers such as John

McPeck, John Ennis, John Chaffee and Richard Paul, who have moved sideways in to the area of

critical thinking research. According to McPeck (1981), critical thinking is the propensity and skill toengage in an activity with reflective scepticism (pp. 7, 9, 152). Writers agree that critical thinking is

not a narrow form of criticality or nay-saying to the views of other people. Ideas are accepted or

rejected based on the evidence used to back those claims and this is done with a view to helping

make better decisions and arriving at the truth (Halpern, 1998, p.449; Verlinden, 2005, pp.17,3,19).

For this reason, the critical thinker finds fault with her own ideas as much as she does with those of

other people.

& Development, 30 (3), 275-287. Retrieved from http://dx.doi.org/10.1080/07294360.2010.500656

2. Critical thinking has been described as a form of student learning that evokes what is higher inhigher education (Jones, 2007, p. 210). As a sub-field of logic, critical thinking is described a form of

reasoning that is focused on testing the validity of premises and the relationship between premises

and conclusions (Alfino, Pajer, Pierce & OBrien Jenks, 2008). From a cognitive psychological

perspective critical thinking can also be seen as a human activity that is focused on achieving specific

goals such as anticipating real-world problems. From this perspective, critical thinking is practical as

well as theoretical in nature (Phillips & Bond, 2004).

Development, 30 (3), 303-315. Retrieved fromhttp://dx.doi.org/10.1080/07294360.2010.501075

3. Critical thinking is the use of those cognitive skills or strategies that increase the probability of a

positive outcome. It is used to describe thinking that is purposeful, reasoned, ands goal directed -

the kind of thinking involved in problem solving, formulating inferences, calculating likelihoods, and

making decisions when the thinker is using skills that are thoughtful and effective for the particular

context and type of thinking task. Critical thinking also involves evaluating the thinking process - the

reasoning that went into the conclusion we've arrived at the kinds of factors considered in making a

decision. Critical thinking is sometimes called directed thinking because it focuses on a desired

outcome. This definition of critical thinking -along with others to a lesser direct degree - emphasizes

implicitly that critical thinking takes time, energy, skill, and dedication. It is frustrating but important

for critical thinkers to be and to stay aware of that not all persons with whom we communicate with

are skilled in critical thinking or do not always exercise their critical thinking skills at every

communication event.Communication is a dialogic event which requires some level of mutual

awareness and cooperation between communicants.

4. Goldbergs 7 Missing Basics

Dr David Goldberg, Co-Director of the Illinois Foundry for Innovation in Engineering

Education is co-founder of a new movement, the Big Beacon. He was NUS DistinguishedVisitor. In 2012-13, he conducted a series of seminars and workshops for FoE students and

staff.

The following is an excerpt from Goldbergs article The Missing Basics and OtherPhilosophical Reflections for the Transformation of Engineering Education.

3. 7 FAILURES OF ENGINEERING EDUCATION & THE MISSING BASICS

The semester has begun. The projects are assigned, and teams of three student engineers and

their advisors are ready to go on the plant trip and find out what the project is really about. Over19 years of advising such teams, Ivefound seven important skills that students have difficulty

with. Although there is significant variation, the following composite set of difficulties is

common enough that most teams require coaching along many, if not all, dimensions discussed.

In particular, senior design students have difficulty

1. asking questions

2. labeling technology and design challenges

3. modeling problems qualitatively

4. decomposing design problems

5. gathering data

6. visualizing solutions and generating ideas

7. communicating solutions in written and oral form

Each of these is briefly considered in turn, associating each of these failings with a prominent

name in intellectual history (Solomon & Higgins, 1996):

Questions. Students go on the plant trip, and the first job is to learn what the project is, what

has been tried, what critical sources of data and theory exist, and what vendors have been 3

helpful in solving related problems. Unfortunately, most student teams have trouble asking

cogent questions. We call this a failure of Socrates 101 in recognition of that philosophers

role in teaching the world to ask.

Labeling. Engineering students learn math and science but are largely ignorant of technology

itself, exhibiting difficulty in labeling the components, assemblies, systems, and processes in

their projects. Moreover, many projects exhibit novel patterns of failure or design challenge,

and the students have difficulty giving such patterns names and sticking to those names. This

we call a failure of Aristotle 101 as the systematic naming and categorization of concepts is

often attributed to that philosopher.

Modeling. With sufficient coaching, students learn the names of extant components and

processes and are able to give names to novel patterns, but then they have difficulty modeling

design challenges qualitatively. Of course, if the problem lends itself to simple calculus or

physics computation, engineering students can plug and chug with the best of them; however,

companies dontpay real money for someone to do routine engineering calculation. Where

students have difficulty is in making lists of system elements or problem categories or in

describing how things work in words This is a failure of Aristotle 102 or Hume 101because of the connections of those philosophers to categorization and causality.

Decomposition. With some help in understanding key causal and categorical relations the

student engineers regain their footing, and then they have trouble decomposing the big design

problem into smaller sub problems. We call this a failure of Descartes 101 because of that

philosophersdiscussions of the fundamental role of decomposition in the solution of

problems.

Gathering data. With the job separated into pieces, usually a number of the pieces depend

on careful data collection from the literature or from the design and execution of careful

experiments. The studentsfirst impulses are often to model mathematically, but an efficientand effective solution often depends on simple experimentation or library work. We call this

failure to resort to empirical work or extant data a failure of Galileo or Bacon 101 because of

these individualscontribution to the creation of systematic empirical science.

Visualization & ideation. Students have trouble sketching or diagramming solutions to

problems, and more generally they have difficulty in brainstorming a sufficiently large

number of solutions. Calling this a failure of da Vinci 101 because of that individuals

renowned imagination and ability to visualize, the problem again is solved with some

coaching.

Communication. Finally, the students have solved the problem, done the experiments, put

together the analyses, and largely solved the problem, and the time has come to make a

presentation or write a report, and to quote the famous line of the Captain from the movieCool Hand Luke, Whatwevegot here is a failure to communicate.Calling this a failure

of Newman 101 (Paul Newman), the situation again calls for significant coaching.

3) How does working in a team help to hone critical thinking skills?

What does an engineer do?

The Faculty of Engineering website (http://www.eng.nus.edu.sg/ugrad/prospective/engdo.html)states:

Engineers innovate and create all kinds of functional systems, products and services for modern living by

applying a combination of mathematical, scientific and engineering fundamentals. Engineers solve

problems and make things work better, more efficiently, and less expensively. We have to thank

engineers for modern conveniences at our homes, schools, offices, hospitals and even on ourselves (for

handphones, MP3 players and notebook computers & etc).

Engineers are designers and builders, making everything from nano-electronic devices, robots,

biopharmaceuticals, and medical equipment to skyscrapers and highly efficient transportation systems

that move millions of people in relative comfort and safety on the ground, sea, air and even in space. In

addition to pushing the frontiers of science and technology to design and create new products and

services, engineers are also involved in the planning, logistics and management of people, processes and

machinery used in the manufacture of products. Engineers ensure that the products they manufacture

are of the highest quality and meet safety standards. Engineers are also involved in marketing of

technological products and services.

Engineers administer large-scale technical, engineering and research projects by being involved in

designing, planning, organizing, allocating resources/budgets and controlling activities that have

engineering/technological components. In such projects, engineers oversee and manage teams of

technical and non-technical personnel. Engineering managers are distinguished from other managers by

the fact that they possess both an ability to apply engineering principles as well as being able to

organize, plan and manage technical projects. Engineers constantly keep pace with the ever-evolvingtechnology and must be adept at handling resources and budgets in order to deliver the most cost-

effective results.

Engineers not only contribute to modern technology but also to other fields including architecture, the

global environment and medicine. Our world has indeed been shaped by some of the greatest

Engineering achievements.

Activity C:In groups, discuss the following:

1) What does an engineer in your field (Chemical Engineering, Civil Engineering,Mechanical Engineering etc.) do?

2) What skills are needed to perform your job? Are they similar to those mentioned in the

article onA global engineer for the global community?3) What is the difference between discipline specific critical thinking and general purpose

critical thinking?

What is communication?

One of the seven basics mentioned by Goldberg is communication. It has been perceived by

many that engineers are brilliant in solving problems but poor at communicating their ideas.

They know their content but are unable to communicate effectively to the audience. Judging bywhat engineers do and their desire to change the world for the better, the ability to communicate

effectively is all the more essential. They need to explain and argue their position for theirengineering purpose to a wider audience. In many cases they have to engage the public.

Effective communication is also important in teamwork. As engineers need to work in teams and

increasingly in a multi-cultural and diverse workplace, expressing their ideas clearly,

contributing differing ideas and arguing which ideas are viable, become easier with bettercommunication strategies.

At NUS, Provost Tan also highlighted the importance of effective communicationin his blog

(http://blog.nus.edu.sg/provost/2011/11/)in November 2011.The view that being able to expressoneself clearly, orally or in written form,is reiterated in a report by Channel News Asia on a

JobStreet com. survey. Conducted in Singapore among 480 fresh graduates and 150 employers in2012, the survey revealed that employers acknowledged the value of good interpersonal andcommunication skills as well as a good command of the English language above qualifications

when hiring fresh graduates.

Activity D: In groups, discuss the following:

1) What is the relationship between critical thinking and communication?2) What possible communication problems could an individual face?3) What possible communication problems could a team face?

4) What strategies can you adopt to communicate effectively as an individual and as a teammember?

A Society with Poor Critical Thinking Skills: The Case for 'Argument' in Education

ByRabbi Dr.ShmulyYanklowitz

15 August 2013

Researchers have shown that most students today are weak in critical thinking skills. They do poorly on

simple logical reasoning tests (Evans, 2002). Only a fraction of graduating high school seniors (6 percent

of 12th graders) can make informed, critical judgments about written text (Perie, Grigg, and Donahue,

2005). This problem applies to both reading and writing. Only 15 percent of 12th graders demonstratethe proficiency to write well-organized essays that consisted of clear arguments (Perie et al., 2005).

Critical thinking and argument skills -- the abilities to both generate and critique arguments -- are crucial

elements in decision-making (Byrnes, 1998; Klaczynski, 2004; Halpern 1998). When applied to academic

settings, argumentation may promote the long-term understanding and retention of course content

(Adriessen, 2006; Nussbaum, 2008a). According to the ancient Greeks, dialogue is the most advanced

form of thought (Vygotsky, 1978). Critical thinking and dialogue are often made manifest in the form of

argument. Dialectical arguments require an appeal to beliefs and values to make crucial decisions, what

Aristotle referred to as endoxa (Walton, Reed, & Macagno, 2008). In all careers, academic classes, and

relationships, argument skills can be used to enhance learning when we treat reasoning as a process of

argumentation (Kuhn, 1992, 1993), as fundamentally dialogical (Bakhtin, 1981, 1986; Wertsch, 1991),

and as metacognitive (Hofer & Pintrich, 1997). Significant differences in approach have emerged as to

how best cultivate the skills necessary to form, present and defend an argument. Differences have

emerged as to whether the best practices include the use of computers, writing exercises, metacognitive

activities, debates, modeling, or frontal instruction. To many "argument" sounds combative and

negative but the use of argument can be constructive and generative.

Epistemological understanding becomes most evident when an individual is confronted with uncertain

or controversial knowledge claims (Chandler et al., 1990; King and Kitchener, 1994; Kuhn et al., 2000;

Leadbeater and Kuhn, 1989). It is imperative that high school students, of diverse personal, moral and

intellectual commitments, become prepared to confront multiple perspectives on unclear and

controversial issues when they move on to college and their careers. This is not only important for

assuring students are equipped to compete in the marketplace of ideas but also to maximize their owncognitive development more broadly. Longitudinal studies focused on high school students (Schommer

et al., 1997) show a positive correlation between educational level and epistemological level. Cross-

sectional studies demonstrate that educational experiences influence epistemological development and

that it is the quality of education and not age or gender that contributes to different developmental

levels of epistemological understanding (Chandler et al., 1990; Leadbeater and Kuhn, 1989). Education is

therefore key.

Argument is a more complex and challenging cognitive skill for students than other genres of reading

and writing, such as exposition or narration. It is also more challenging for most teachers who may not

have the knowledge or experience of working with argumentative reading and writing (Hillocks, 1999,

2010). In addition, most teachers try to avoid conflict when it comes to learning (Powell, Farrar, and

Cohen, 1985).

Many teachers have observed that students sitting in classrooms today are bored by the frontal

authoritarian model of learning. For years, as a student, I was told to take out my notebook and copy

what was written on the board. A curriculum in which they are active participants and engaged in

democratic, and cognitively challenging for students works better. In the frontal model, teachers provide

the questions and answers. In the argument model, the students provide the questions and the answers

while the teachers provide the structure, the facilitation, and the guidance. Students gain the necessary

skills to be critical thinkers in a complex society with many different agendas, facts, and perspectives.

Some argue that too much autonomy is given to students in a student-centered environment. But the

risk is much greater with frontal lecture education: that our students master content but do not gain the

cognitive, moral, and epistemic development necessary to become autonomous critical thinkers. The

choice of reading matter for students is also an important factor. Students are unlikely to develop

critical thinking skills naturally when their class reading assignments consist only of narrative and

explanatory texts, as opposed to argumentative texts (Calfee & Chambliss, 1987).

The goal of an argument curriculum is to enhance the development of the responsible citizens and the

pedagogical methodology consists of cultivating argument skills, epistemic development, and moral

development. School-based nurturance of this development will lead to students' autonomous critical

thinking and their formation as responsible citizens. We must invest in the education of our youth. They

are our future!
