Critical Thinking
 Sitting on top of your
shoulders is one of the finest
computers on the earth.
 But, like any other muscle in
your body, it needs to be
exercised to work its best.
 That exercise is called
THINKING.
I think, therefore I am.
- Rene Descartes

What is critical thinking?
 Commonly called “problem solving”
 Not being content with the first solution to a problem,
but thinking more deeply about it.
 Knowing, understanding, analyzing, synthesizing,
applying and evaluating the idea or problem
 Looking for what is implied in a question rather than
what is stated
 Applying the rules of logic to problem solving
 Not letting reason be clouded by emotion

3

Four Aspects of Critical Thinking
 Abstract Thinking:
thinking past what your senses tell you
 Creative Thinking:
thinking “out of the box,” innovating
 Systematic Thinking:
organizing your thoughts into logical steps
 Communicative Thinking:
being precise in giving your ideas to others.

4

Critical Thinking: What is involved?
 Question: what is being asked?
 Purpose: why do I want the answer?
 Point of View: where do I stand to look at the
question?
 Information: what data do I have?
 Concepts: what ideas are involved?
 Assumptions: what am I taking for granted?
 Inferences: what conclusions am I drawing?
 Consequences: what are the implications of my
question?

5

Critical Thinkers
 Acknowledge personal limitations.
 See problems as exciting challenges.
 Have understanding as a goal.
 Use evidence to make judgments.
 Are interested in others’ ideas.
 Are skeptical of extreme views.
 Think before acting.
 Avoid emotionalism
 Keep an open mind

6

Uncritical Thinkers
o Pretend to know more than they do.
o Get annoyed by problems.
o Are impatient.
o Judge on first impressions and
intuition.
o Focus on their own opinions.
o Look only for ideas like their own.
o Are guided by feelings rather than
thoughts.
o Claim that thinking gives them a
headache.
Don’t think
about it,
just sign it!

Inductive and Deductive
Reasoning
 Inductive Reasoning
Specific Reasoning Broad Principles
Example: My history All college courses
class requires a lot of have a lot of reading
reading
 Deductive Reasoning
Broad Specific
Generalizations Conclusions
Example: All college My art history course
courses are hard will be hard

9

The IDEAL Method
 Identify the problem.
 Define the problem.
 Explore alternative approaches.
 Act on the best strategies.
 Look back to evaluate the effects.
Yes, ladies and
gentlemen, it’s
IDEAL!

10

Ask Questions
 One quality of a good critical thinker is the ability to ask
on-target questions.
 If you don’t usually ask questions, is it because you
 Fear embarrassment?
 Worry what others will think of you?
 Worry that the instructor will think your question is strange?
 Worry that others will think you’re showing off?
 When you don’t ask questions, you sacrifice your
education.
 If you don’t take risks, you won’t get the maximum
benefit in developing your mind.
Yes!
Ask me!

11

There’s No Such Thing as a
Stupid Question (Usually)
There are unwelcome questions.
Don’t ask questions that detract from
the momentum of the class.
Don’t ask questions that focus more
on self-concerns than on the needs of
the class.
Don’t ask questions that demonstrate
you failed to pay attention.
 Don’t ask silly questions.
Can I draw
you a
conclusion?
Well, can I?

12

Offer Criticism
 You will most likely be asked to judge or
evaluate issues in college.
 First decide whether you like what you
are being asked to judge.
 Consider both positive and negative
attributes.
 Use examples to support your judgment.
 Don’t be intimidated by this kind of
assignment; your instructors want you to
develop your critical thinking skills.

13

Make the Right Inferences
 You are constantly making inferences.
 Inferences are interpretations that you derive
from processing cues in a situation.
 A plausible inference is a judgment that is
logical, and possibly accurate.
 Sometimes inferences become assumptions—
something we believe to be true and act on as
though it were.
 Inferences can be tricky. It is easy to be wrong
and you may operate on faulty assumptions until
you are informed otherwise.

14

Four Common Decision Making
Problems
 Snap decisions
 Don’t jump to conclusions!
 Narrow thinking
 Broaden your vistas!
 Sprawling thinking
 Don’t beat around the bush!
 Fuzzy thinking
 Keep it sharp! Keep it relevant!

15

What is a Claim?
 A claim is a statement which can be either true or false, but not
both.
 A claim is an assertion you want to have accepted as a fact and
not be disputed.
 When evaluating a claim, you have three choices:
 accept the claim
 reject the claim
 suspend judgment until you have more information
What is an Argument?
 An argument is a set of claims.
 Arguments begin with premises and lead to a conclusion
 A good argument is one in which the premises lead
logically to a strong or valid conclusion.
I’m
stakin’
a claim!

16

Form Strong Arguments
 Be sure the conclusion follows logically from the
premises.
 Leave out faulty or dubious premises.
 Use precise language to pinpoint your claim.
 Avoid making claims you can’t prove.
This is a perfectly logical
argument (called a syllogism.)
It only has one small problem:
NASA hasn’t found any green
men on Mars. Oh, well…

17

Know Your Own Biases
 Everyone has strong preferences and prejudices
that may prevent us from evaluating arguments
fairly.
 Acknowledging these can increase the likelihood
of coming up with more effective arguments.
 Good reasoners guard against their own “soft
spots” to increase their objectivity.
 Be honest with yourself: “Am I opinionated?

18

Refine Your Reasoning
 Be willing to argue
 Use deductive reasoning
 Check your assumptions
 Know your own biases
 Observe carefully
 Stay positive and persistent
 Show concern for accuracy
 Take time before concluding

19

What Makes a Creative Thinker?
 They actively pursue experiences that are
aesthetically pleasing.
 They enjoy taking a unique approach to
things.
 They love the process of creating.
 They are flexible and like to play with
problems.
 They take risks and learn from their
mistakes.
 They strive to evaluate their work fairly.
 They thrive when they think of assignment
guidelines as a launching point for their
imagination.

20

Nurture Your Own Creativity
 Don’t accept other people’s blueprints.
 Be vigilant about what others can’t see.
 Differentiate the good from the bad.
 Take the plunge before you’re an expert.
 Concentrate on the big picture.
 Take sensible risks.
 Motivate yourself from inside.
 Shape environments that will support your
creativity.
 Actively pursue your creative life.

21

Critical Thinking:
A Skill to Carry You Through Life
Professors and future employers value your ability
to perform these critical thinking skills:
 Manage and interpret information
 Examine exciting ideas and develop new ones
 Pose logical and cogent arguments
 Recognize reliable evidence
 Be proactive rather than reactive
 Think things through in depth. Always
be
reasonable

22

Why College Encourages Critical Thinking
Remember:
 Thinkers are generally “movers and shakers.”
 Sometimes how you solve a problem is as important as
the solution.
 Open ended questions of “Why?”, “How?” or “What If?”
have no simple, clear-cut answers.
 There are many valid points of view!
 The greatest gift a college can give you is an open mind.
