Jamie Davies
How many uses can you think
of for a paper clip?
Learning Outcomes
By the end of the session participants:
•Should be able to describe what critical thinking is.
•Have reflected on teaching critical thinking skills.
•Should be able to describe what goes into a toaster.
•Have discussed strategies to embed critical thinking skills into the curriculum.
Knowing a great deal is not the same as being smart;
intelligence is not information alone but also judgment, the
manner in which information is collected and used.
Carl Sagan
Critical thinking is the ability to think clearly and rationally. It includes the ability to engage in reflective and independent thinking.
- Analysing arguments, claims, or evidence (Ennis, 1985; Facione, 1990; Halpern, 1998; Paul, 1992)
- Making inferences using inductive or deductive reasoning (Ennis, 1985; Facione, 1990; Paul, 1992; Willingham, 2007)
- Judging or evaluating (Case, 2005; Ennis, 1985; Facione, 1990; Lipman, 1988)
- Making decisions or solving problems (Ennis, 1985; Halpern, 1998; Willingham, 2007).
(Lai, 2011)
How to make a piece of toast?
Now, imagine you don’t have a toaster … what would you do?
How could you make the toast?
In small groups you have 90 seconds to write a set of instructions as to how to make the perfect piece of toast.
Left to his own devices he
couldn’t build a toaster. He could just about make a sandwich and
that was it. Douglas Adams, Mostly Harmless, 1992
It takes an entire civilisation to build a toaster

Correlation not Causation
CT| Criticisms of Psychology
1. Is psychology only common sense?
2. Do psychological theories provide new insight into the human condition or do they document the obvious?
3. Does psychology simply formalise what any amateur already knows intuitively?
“Day after day social scientists go out into the world. Day after day they discover that people’s behavior is pretty much what you’d expect.”
Cullen Murphy, Editor, Atlantic Monthly (1990)
TASK
In pairs look at the conclusions from Lazarsfeld (1949) and suggest reasons for the findings of the study.
What could have led to his findings?
Do the conclusions make sense?
[5 minutes]
Paul Lazarsfeld (1949) | The American Soldier - An Expository Review
1. Better educated soldiers suffered more adjustment problems than less educated soldiers.
2. Southern soldiers coped better with the hot South Sea Island climate than Northern soldiers.
3. White privates were more eager to be promoted officers than Black privates.
4. As long as the fighting continued, soldiers were more eager to return home than after the war ended.

Hindsight Bias
1. “I knew it all along phenomena”– the tendency to perceive something as obvious or unavoidable, after learning of the outcome.
2. Study of Hindsight bias: Teigen (1986)• Evaluate actual proverbs and their opposites
Actual Proverb• Fear is stronger than love.• He that is fallen cannot help
him who is down.• Wise men make proverbs
and fools repeat them.
Opposite• Love is stronger than fear.• He that is fallen can help
him who is down.• Fools make proverbs and
wise men repeat them.
Discuss a CT class activity
How could you embed critical
thinking into your classroom
activities?
What is the quality of the evidence?
Could the relationship have happened by chance?Is there a control or comparison group?
Is the conclusion causal using correlational data?
Are there any confounding variables?
Are we over generalising based on an unrepresentative sample?
Are there any biases in the research or data collection methods?
Can you actually falsify the theory?
Is the study claiming to have found the answer?
“… science must begin with myths, and with the criticism of
myths; neither with the collection of observations, nor with the
invention of experiments, but with the critical discussion of
myths, and of magical techniques and practices.”
Popper (1963) p66.
