6. Thinking is purposeful, organized, cognitive
process that we use to make sense of our world.

7. Types of Thinking

8. What is Critical Thinking?

9. Richard Paul.. Father of Critical Thinking
“Critical thinking is thinking about your thinking while you’re
thinking in order to make your thinking better.”

10.  Critical Thinking is the ability to
apply reasoning, and logic to unfamiliar
Ideas, options and situations.
 Effectively identify, evaluate and
analyse arguments.
 Discover and overcome Assumptions.
 Make reasonable and intelligent decisions
on what to believe and what not to.

18. LOGIC
Logic is the science of reasoning, proof, thinking, or
inference.
Logic allows us to analyze arguments, and determine
whether they are correct or not.

19. Argument : The Primary Focus of Logic
An Argument is any group of propositions of which one (conclusion) is
claimed to follow from the others( premises) which provides support
for the truth of that one.

20. Lets have a look at this Argument:
So human beings are mammals
Human beings give birth to babies,
All Mammals give birth to babies,
Major Premise
Minor Premise
Conclusion

21. Lets have a look at this Argument:
All people are Animals
All People are Mammals,
All Mammals are four footed animals,
Major Premise
Minor Premise
Conclusion

22. • An argument is a set of statements with at least one conclusion
and one reason that supports the conclusion.
• In real life settings, arguments are complex with reasons that
run counter to the conclusion, stated and unstated
assumptions, irrelevant information, and intermediate steps.
• The critical thinking skills lie in identifying conclusions, rating
the quality of reasons, and determining the overall strength of
an argument

Model for Critical Thinking
 How did I reach this
inference?
 Is my inference logical?
 What information/data
is relevant to this
problem?
 Is this information
relevant?
 How do I know that this
data is correct?
 What is the problem
that I am trying to
solve?
 Is this problem, simple
or complex?
 What will happen if I
decide to do X?
 What will happen if I
decide not to do X?
 How am I looking at
this problem? Is it
reasonable?
 Am I having difficulty
looking at this problem
with a view with which
I disagree?
 What am I assuming or
taking for granted?
 Am I assuming
something that I should
not?
