Focus
This activity provides opportunities for students to synthesise information
using a debate on the management of exotic pest fish species.
Estimated time: 2 x 45 minutes
Materials
Listed below are examples of possible topics.
- Tilapia should be seen as a resource not a pest.
- We should concentrate on long-term, high-tech eradication options instead
of short-term sustained control techniques.
- We should spend money on eradicating pest fish from areas where they are
already present, not concentrate on stopping them getting to new areas.
- The penalties in place for possessing noxious fish are reasonable.
- Goldfish should be declared a noxious species.
- People should not be allowed to keep non-native fish in their aquariums.
Teaching strategies
Working scientifically
(U: examining and evaluating, C: arguing a position, responding and debating,
clarifying ideas and concepts)
One option is to use a directed discussion that will engage more
students in preparation and delivery of arguments than a formal debate.
Procedure for directed discussion:
- Divide the class into two groups Group A takes Position 1 and Group B
takes Position 2.
- Both groups are given thirty minutes to prepare arguments and need to
select five speakers to present the group point of view.
- Arguments are presented as follows: Group A Speaker 1, Group B Speaker
1, Group A Speaker 2, Group B Speaker 2 and so on, until five speakers have
delivered their arguments.
- Speakers from Groups A and B are invited to add more arguments and/or
refute the other groups arguments. These speakers should not be any
of the previous five speakers of both groups. Points may be scored, as for
a debate.
OR
The debate may take the form of a formal debate follow normal procedures
as stated in Queensland syllabus (A Guide to Genres in English).
