HOW TO HAVE EFFECTIVE COMMUNICATION?
In HKCEE, 2 marks are given for effective communication for each structured exercise. Therefore students can almost get 6 marks for the 3 chosen questions.
The criteria are as follows:
1. Elaboration
e.g. Air pollution is serious in Hong Kong (Too simple)
=> Air pollution is serious in Hong Kong because there are lots of cars on the streets.
2. Explanation
e.g. Air pollution is serious in Hong Kong
because there are lots of cars on the streets.
(How does large number of cars link with air
pollution? No explanation is provided)
=> Air pollution is serious in Hong Kong
because there are lots of cars on the streets.
Cars emit lots of poisonous carbon monoxide and
sulphur dioxide which pollute the
environment.
3. Data
e.g. Air pollution is serious in Hong Kong.
(How serious is air pollution? No data!)
=> Air pollution is serious in Hong Kong.
Air pollution can be measured by Air
Pollution Index (API). The highest air
pollution index measured in Tung Chung in
Dec, 1999 was 161.
4. Well-labeled diagram
Well-labeled diagram can in fact summarize lots of written arguments already.
5. Example
e.g. Air pollution is serious in Hong Kong.
(Hong Kong is large. Which part of Hong
Kong has serious air pollution)
=> Air pollution is serious in Hong Kong
especially in Causeway Bay, Central.
6. Using keywords & geographical terms
Remember you are writing a geography essay, not a composition, therefore some geographical terms & keywords MUST be found in your essays.
e.g. Air is dirty in Hong Kong because lots of black smoke and dust is given out from cars. It cannot go away because of the tall buildings in Hong Kong. (The arguments are correct but even a primary student can answer like this.)
Geography students should use the terms that
you have learnt to answer, for example:
Air Pollution is serious /The Air Pollution Index is high in Hong Kong (Air is
dirty in Hong Kong). Cars emitted (give out) lots of poisonous gases like carbon monoxide,
sulphur dioxide and respirable suspended particulates (dust and smoke). Tall buildings
result in calm wind condition and block the dissipation of these gases. As a result, most
of the pollutants are trapped in the lower atmosphere.
7. Integration of concepts
e.g. Air pollution is serious in Hong Kong
because there are lots of cars on the streets.
(Air pollution should not be the result of
poisonous gases emitted from cars only.
There should be other factors too. Students
should link different factors together)
=> Air pollution is serious in Hong Kong
because there are lots of cars on the streets.
The poisonous gases emitted are trapped in the
lower atmosphere because of tall buildings
which block the release of gases and result in
calm wind condition.
