5. • developed by White and
Gunstone (1992)
• to uncover individual students’
predictions, and their reasons
for making these, about a
specific event.

Understanding. Great Britain: Falmer Press.

6. • POE is a strategy often
used in science
• It works best with
demonstrations that allow
immediate observations,
and suits Physical and
Material World contexts.

Understanding. Great Britain: Falmer Press.

7. When to Use?
finding out
students' initial
ideas

8. When to Use?
providing
teachers with
information
about students’
thinking;

9. When to Use?
generating
discussion

10. When to Use?
motivating
students to
want to explore
the concept

11. When to Use?
generating
investigations

12. Educational Theory
Constructivism is the
theory that
says learners
construct knowledge
rather than just
passively take in
information.

13. Constructivism
 John Dewey's Cognitive
Constructivism
 Jean Piaget's Cognitive
Constructivism
 Lev Vygotsky's Social
Constructivism
 Bruner's Constructivist
Learning Theory.

14. POE: How the
strategy works
What to do
•Set up a
demonstration of an
event, related to the
focus topic, that may
surprise students, and
which can be observed.
•Tell the students what
you are going to be
doing.

15. POE: How the
strategy works
What to do
•Set up a
demonstration of an
event, related to the
focus topic, that may
surprise students, and
which can be observed.
•Tell the students what
you are going to be
doing.

16. POE: How the strategy works
Step 1: Predict
•Ask the students to independently
write their prediction of what will
happen.
•Ask them what they think they will
see and why they think this.

17. Step 1: Predict

18. POE: How the strategy works
Step 2: Observe
•Carry out the demonstration.
•Allow time to focus on observation.
•Ask students to write down what
they do observe.

19. Step 2: Observe

20. POE: How the strategy works
Step 3: Explain
• Ask students to amend or add to their
explanation to take account of the
observation.
• After students have committed their
explanations to paper, discuss their ideas
together

21. Step 3: Explain
