Critical Thinking?

Everyone thinks; it is our nature to do so. But

much of our thinking, left to itself, is biased,

unclear, partial, uninformed or down-right

prejudiced. Yet the quality of our life and that

of what we produce, make, or build depends

Everyone thinks …..

of what we produce, make, or build depends

precisely on the quality of our thought. Poor

thinking is costly, both in money and in

quality of life. Excellence in thought,

however, must be systematically cultivated.- Richard Paul

Thus…Students in school should be taught how to think critically. Classes should be designed based on reasoning and

7/25/2010 Dr. Shadia Yousef Banjar 19

be designed based on reasoning and rational grounds and not as series of facts.

What Is Critical Thinking?

“Critical thinking is the ability to apply reasoning and

logic to unfamiliar ideas, opinions, and situations.

7/25/2010 Dr. Shadia Yousef Banjar 20

logic to unfamiliar ideas, opinions, and situations.

Thinking critically involves seeing things in an open-

minded way. This important skill allows people to look

past their own views of the world and to adopt a more

aware way of viewing the world.”What is Critical Thinking?

HOW DO YOU DEFINE CRITICAL

pursuit of relevant and reliable knowledge

about the world. •Another way to describe it is reasonable,

•Another way to describe it is reasonable,

reflective, responsible, and skillful thinking

that is focused on deciding what to believe or

do.

Page 23: Critical Thinking, By Dr. Shadia Yousef Banjar

•Critical thinking is not being able to process

information well enough to know to stop for red lights or

whether you received the correct change at the

supermarket. •Such low-order thinking, critical and useful though it

7/25/2010 Dr. Shadia Yousef Banjar 23

•Such low-order thinking, critical and useful though it

may be, is sufficient only for personal survival; most

individuals master this.

Page 24: Critical Thinking, By Dr. Shadia Yousef Banjar

•True critical thinking is higher-order thinking,

enabling a person to, for example, responsibly

judge between political candidates, serve on a

murder trial jury, evaluate society's need for

nuclear power plants, and assess the

consequences of global warming.•

7/25/2010 Dr. Shadia Yousef Banjar 24

consequences of global warming.• Critical thinking enables an individual to be a

responsible citizen who contributes to society, and

not be merely a consumer of society's

distractions.

Page 25: Critical Thinking, By Dr. Shadia Yousef Banjar

•A person who thinks critically can ask appropriate

questions, gather relevant information, efficiently

and creatively sort through this information, reason

logically from this information, and come to reliable

and trustworthy conclusions about the world that

enable one to live and act successfully in it. •Children are not born with the power to think

7/25/2010 Dr. Shadia Yousef Banjar 25

•Children are not born with the power to think

critically, nor do they develop this ability naturally

beyond survival-level thinking. Critical thinking is a

learned ability that must be taught. Most individuals

never learn it.

Page 26: Critical Thinking, By Dr. Shadia Yousef Banjar

•Critical thinking cannot be taught reliably to

students by peers or by most parents.• Trained and knowledgeable instructors are

necessary to impart the proper information and

skills. •Critical thinking can be described as the

7/25/2010 Dr. Shadia Yousef Banjar 26

•Critical thinking can be described as the

scientific method applied by ordinary

people to the ordinary world.

Page 27: Critical Thinking, By Dr. Shadia Yousef Banjar

•This is true because critical thinking mimics the well-known

method of scientific investigation: a question is identified, an

hypothesis formulated, relevant data sought and gathered,

the hypothesis is logically tested and evaluated, and reliable

conclusions are drawn from the result.• All of the skills of scientific investigation are matched by

critical thinking, which is therefore nothing more than

scientific method used in everyday life rather than in

specifically scientific disciplines or endeavors. •

7/25/2010 Dr. Shadia Yousef Banjar 27

specifically scientific disciplines or endeavors. •Critical thinking is scientific thinking. •A scientifically-literate person, such as a math or science

instructor, has learned to think critically to achieve that level

of scientific awareness. But any individual with an advanced

degree in any university discipline has almost certainly learned

the techniques of critical thinking.

Page 28: Critical Thinking, By Dr. Shadia Yousef Banjar

•Critical thinking is the ability to think for one's self and

reliably and responsibly make those decisions that affect

one's life. •Critical thinking is also critical inquiry, so such critical

thinkers investigate problems, ask questions, pose new

answers that challenge the status quo, discover new

information that can be used for good or ill, question

7/25/2010 Dr. Shadia Yousef Banjar 28

information that can be used for good or ill, question

authorities and traditional beliefs, challenge received

dogmas and doctrines, and often end up possessing power

in society greater than their numbers.

Page 29: Critical Thinking, By Dr. Shadia Yousef Banjar

•It may be that a workable society or culture can tolerate only a

small number of critical thinkers, that learning, internalizing, and

practicing scientific and critical thinking is discouraged. Most

people are followers of authority: most do not question, are not

curious, and do not challenge authority figures who claim

special knowledge or insight. Most people, therefore, do not

think for themselves, but rely on others to think for them. Most

people indulge in wishful, hopeful, and emotional thinking,

7/25/2010 Dr. Shadia Yousef Banjar 29

believing that what they believe is true because they wish it,

hope it, or feel it to be true. Most people, therefore, do not think

critically.

Page 30: Critical Thinking, By Dr. Shadia Yousef Banjar

•Critical thinking has many components. Life can be

described as a sequence of problems that each

individual must solve for one's self. Critical thinking skills

are nothing more than problem solving skills that result

in reliable knowledge. Humans constantly process

information. Critical thinking is the practice of processing

this information in the most skillful, accurate, and

rigorous manner possible, in such a way that it leads to

7/25/2010 Dr. Shadia Yousef Banjar 30

rigorous manner possible, in such a way that it leads to

the most reliable, logical, and trustworthy conclusions,

upon which one can make responsible decisions about

one's life, behavior, and actions with full knowledge of

assumptions and consequences of those decisions.

Page 31: Critical Thinking, By Dr. Shadia Yousef Banjar

Raymond S. Nickerson (1987) characterizes a good critical thinker in

terms of knowledge, abilities, attitudes, and habitual ways of

behaving.

Here are some of the CHARACTERISTICS of such a thinker:

uses evidence skillfully and impartially

A GOOD CRITICAL THINKER

7/25/2010 Dr. Shadia Yousef Banjar 31

uses evidence skillfully and impartially

organizes thoughts and articulates them concisely and coherently

distinguishers between logically valid and invalid inferences

suspends judgment in the absence of sufficient evidence to support a

decision

understands the difference between reasoning and rationalizing

attempts to anticipate the probable consequences of alternative actions

Page 32: Critical Thinking, By Dr. Shadia Yousef Banjar

understands the idea of degrees of belief

sees similarities and analogies that are not superficially apparent

can learn independently and has a long-lasting interest in doing

so

applies problem-solving techniques in domains other than those

in which learned

can structure informally represented problems in such a way that

7/25/2010 Dr. Shadia Yousef Banjar 32

formal techniques, such as mathematics, can be used to solve

them

can strip a verbal argument of irrelevancies and phrase it in its

essential terms

Page 33: Critical Thinking, By Dr. Shadia Yousef Banjar

habitually questions one's own views and attempts to

understand both the assumptions that are critical to those views

and the implications of the views

is sensitive to the difference between the validity of a belief

and the intensity with which it is held

is aware of the fact that one's understanding is always limited,

often much more so than would be apparent to one with a

noninquiring attitude

7/25/2010 Dr. Shadia Yousef Banjar 33

noninquiring attitude

recognizes the fallibility of one's own opinions, the probability

of bias in those opinions, and the danger of weighting evidence

according to personal preferences

This list serves to indicate the type of thinking and approach to

life that critical thinking is supposed to be

Page 34: Critical Thinking, By Dr. Shadia Yousef Banjar

A Definition:

Critical thinking is the art of analyzing and

evaluating thinking with a view to improving it.

Novice Versus Expert Thinker

• Expert thinkers– Quickly identify relevant information.

– Can formulate a solution with “sketchy” information .

• Novice thinkers

• Novice thinkers– Consider all information equally important.

– Develop hypothesis, test hypothesis.

– Cannot focus on central issues.

Cultivated Critical Thinkers

Well cultivated critical thinkers:

• are able to raise vital questions and problems, as well as formulate and present them clearly.

• can gather and assess information and interpret it effectively.

• can reach well-reasoned conclusions and solutions to

7/25/2010 Dr. Shadia Yousef Banjar 41

• can reach well-reasoned conclusions and solutions to problems while testing them against relevant criteria and standards.

• can be open-minded.

• can communicate effectively with others in figuring out

solutions to complex problems.

Pitfalls……

• Teaching for critical thinking takes more time

to prepare.

• Teaching for critical thinking will reduce the

amount of “material” covered.

amount of “material” covered.

• Teaching for critical thinking is not popular

with students in the beginning.

• BUT…

Page 44: Critical Thinking, By Dr. Shadia Yousef Banjar

How Can One Become a Critical Thinker?

• By asking pertinent questions (of self as well as others);

• By assessing statements and arguments;

• By developing a sense of observation and curiosity;

• By listening carefully to others, thinking about what they say, and giving feedback;

• By observing with an open mind;

• By making assertions based on sound logic and solid

7/25/2010 Dr. Shadia Yousef Banjar 44

• By becoming interested in finding new solutions;

• By examining beliefs, assumptions, and opinions and weighing them against truth.• By developing a “thinker’svocabulary”.

•on sound logic and solid evidence;

• By sharing ideas with others;

• By becoming an open-minded listener and reader;

• By engaging in active reading and active listening!

Page 45: Critical Thinking, By Dr. Shadia Yousef Banjar

Critical thinking begins when you

question beyond what is given.

You want to know more:

• how something happens,

• why it happens, and further

7/25/2010 Dr. Shadia Yousef Banjar 45

• why it happens, and further

• what will happen if something changes.

Critical thinking therefore requires a conscious level of

processing, analysis, creation and evaluation of possible

outcomes, and reflection.

Page 46: Critical Thinking, By Dr. Shadia Yousef Banjar

If you’re a critical thinker,

you think.

•You are willing to examine your beliefs, assumptions,

….No surprise….

7/25/2010 Dr. Shadia Yousef Banjar 46

•You are willing to examine your beliefs, assumptions,

and opinions and weigh them against facts.

• You are willing to evaluate the generalizations and

stereotypes you have created and are open to change,

if necessary.

Page 47: Critical Thinking, By Dr. Shadia Yousef Banjar

Critical thinkers listen carefully.

7/25/2010 Dr. Shadia Yousef Banjar 47

•If you’re a critical thinker, you listen carefully to what

others are saying and are able to give feedback.

•You are able to suspend judgment until all the facts

have been gathered and considered.

Page 48: Critical Thinking, By Dr. Shadia Yousef Banjar

Critical thinkers look for

evidence….

•If you’re a critical thinker, you look for

evidence to support your assumptions and

7/25/2010 Dr. Shadia Yousef Banjar 48

evidence to support your assumptions and

beliefs.

• You examine problems closely and are

able to reject information that is incorrect

or irrelevant.

Page 49: Critical Thinking, By Dr. Shadia Yousef Banjar

Critical thinkers are curious.

They are interested in knowing all there is

about a topic. They look for new and better

ways to do everything. They are not the

person who will settle for “…because that is

7/25/2010 Dr. Shadia Yousef Banjar 49

person who will settle for “…because that is

the way we have always done it.”

Page 50: Critical Thinking, By Dr. Shadia Yousef Banjar

Therefore…through experience, as a critical

thinker, you will:

• identify information that is being put forth as an

argument and break it down to its basic components for

evaluation.

• construct alternative interpretations

7/25/2010 Dr. Shadia Yousef Banjar 50

• construct alternative interpretations

• be willing to explore diverse perspectives

• be willing to change personal assumptions when

presented with valid information

• be willing to ask difficult questions and the ability to

receptive to opposing viewpoints.

Page 51: Critical Thinking, By Dr. Shadia Yousef Banjar

• Critical thinking is, in short, self-directed, self-

disciplined, self-monitored, and self-corrective thinking.

• It requires accurate standards of excellence and

mindful command of their use.

• It entails effective communication and problem solving

abilities and a commitment to overcome our native

7/25/2010 Dr. Shadia Yousef Banjar 51

abilities and a commitment to overcome our native

egocentrism and sociocentrism.

Page 52: Critical Thinking, By Dr. Shadia Yousef Banjar

A CRITICAL THINKER CONSIDERS THE ELEMENTS OF

REASONING:

1. Purpose, Goal, Objective, or End in View

2. Question at Issue (or Problem to Be Solved)

3. Point of View, Frame of Reference, Perspective,

Orientation

4. Assumptions (presuppositions, what is taken for granted)

7/25/2010 Dr. Shadia Yousef Banjar 52

4. Assumptions (presuppositions, what is taken for granted)

5. Information (data, facts, observations, experiences)

6. Concepts (theories, definitions, axioms, laws, principles,

models)

7. Interpretation & Inferences (conclusions, solutions)

8. Implications & Consequences (Where does this thinking

lead? What will result if this thinking is turned into action?)

Whenever we think,

we think for a purpose,

within a point of view,

based on assumptions,

leading to implications and consequences.

UNIVERSAL STRUCTURES OF THOUGHT

7/25/2010 Dr. Shadia Yousef Banjar 54

We use data, facts, and experiences,

to make inferences and judgments,

based on concepts and theories,

in attempting to answer a question or solve a problem.

Page 55: Critical Thinking, By Dr. Shadia Yousef Banjar

QUESTIONS IMPLIED BY THE UNIVERSAL

STRUCTURES OF THOUGHT: [Use these questions

when beginning work]

•What is my fundamental purpose?

•What is the key question I am trying to answer?

•What information do I need in order to answer my

question?

•What is the most basic concept in the question?

7/25/2010 Dr. Shadia Yousef Banjar 55

•What is the most basic concept in the question?

•What assumptions am I using in my reasoning?

•What is my point of view with respect to the issue?

•What are my most fundamental inferences or

conclusions?

•What are the implications and possible consequences

of my reasoning (if my reasoning is valid?

Universal Intellectual Standards

• Clarity : If a statement is unclear we cannot

evaluate its fit with the other standards.

• Accuracy : Accuracy = TRUTH. Is it true?

• Precision : Is there enough detail to completely

7/25/2010 Dr. Shadia Yousef Banjar 56

• Precision : Is there enough detail to completely

understand the statement.

• Relevance : Is the information connected to the

question at hand?

Page 57: Critical Thinking, By Dr. Shadia Yousef Banjar

• Depth: Does the statement, fact, etc. address the complexity of the issue?

• Breadth: Are there other points of view or other ways to consider this question? Are you considering the key factors?

• Logic: Does it make sense? Can you make that conclusion based on the information and evidence?

7/25/2010 Dr. Shadia Yousef Banjar 57

• Significance: Is this the most important problem to

consider? Is this the central idea to focus on? Which of

these facts are most important?

• Fairness: Do I have any vested interest in this issue?

Am I sympathetically representing the viewpoints of

others?

To understand reasoning properly, however, we need to

understand how it differs from mere thinking.

•When we are merely thinking our thoughts simply come to us,

one after another: when we reason we actively link thoughts

together in such a way that we believe one thought provides

support for another thought.

•This active process of reasoning is termed inference.

• Inference involves a special relationship between different

7/25/2010 Dr. Shadia Yousef Banjar 63

• Inference involves a special relationship between different

thoughts: when we infer B from A, we move from A to B because

we believe that A supports or justifies or makes it reasonable to

believe in the truth of B.

Page 64: Critical Thinking, By Dr. Shadia Yousef Banjar

The difference between mere thinking and reasoning or inference is easy to

understand through examples. Consider the following pairs of sentences:

1. Alan is broke, and he is unhappy.

Alan is broke, therefore he is unhappy.

2. Anne was in a car accident last week, and she deserves an extension

on her essay.

Anne was in a car accident last week, so she deserves an extension on

her essay.

3. This triangle has equal sides and equal angles.

This triangle has equal sides; hence it has equal angles.

7/25/2010 Dr. Shadia Yousef Banjar 64

This triangle has equal sides; hence it has equal angles.

Notice that the first sentence in each pair simply asserts two thoughts but

says nothing about any relationship between them, while the second

sentence asserts a relationship between two thoughts. This relationship is signaled by the words therefore, so, so, and hence. hence. These are called inference

indicators: words that indicate that one thought is intended to support (i.e., to

justify, provide a reason for, provide evidence for, or entail) another thought.

Working Assumptions

• Active learning is necessary for the teaching of critical thinking.

• Critical thinking should be integrated into every aspect of

7/25/2010 Dr. Shadia Yousef Banjar 101

• Critical thinking should be integrated into every aspect of the educational process.

• Students should be made aware of the thinking process.

• Critical thinking must be taught explicitly.

• Process is as important as content.

Page 102: Critical Thinking, By Dr. Shadia Yousef Banjar

Working Definitions

• Active Learning - “students involved in doing

things & thinking about the things they are doing”

• Critical Thinking - “reasonable reflective thinking

that is focused on deciding what to do and what to

that is focused on deciding what to do and what to

believe” OR “interpreting, analyzing or evaluating

information, arguments or experiences with a set of

reflective attitudes, skills, and abilities to guide our

thoughts, beliefs and actions” OR “examining the

thinking of others to improve our own”

Thinking Tools

• A Thinking ToolThinking Tool is an instrument that can help us in using our minds systematically and effectively.

• With the use of thinking tools, the intended ideas will be arranged more systematically, clearly, and easy to be understood.

There are 4 types of THINKING TOOLS:

There are 4 types of THINKING TOOLS:

• Questioning

• Concepts

• Mindmaps

• Cognitive Research Trust

Page 104: Critical Thinking, By Dr. Shadia Yousef Banjar

Questioning

Questioning is one approach to motivate

others to:

• Get information

• Test understanding
