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.
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
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.
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?
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
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!

The IDEAL Method
 Identify the problem.
 Define the problem.
 Explore alternative approaches.
 Act on the best strategies.
 Look back to evaluate the effects.
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!
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?
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.
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.
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!
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!
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.
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?
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
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.
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.
Critical Thinking:
A Skill to Carry You Through Life
Trainers and 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.
Why Encourage 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.
Thank you…
