2. INTRODUCTION
• STELLA is an example of simulation model that helps to
solve problems or events that can be used to teach
someone how to do a process of making a model.
• It also was packaged with an easy, intuitive interface that
allows users to construct dynamics models that stimulate
biological systems.
3. Normal Graph
Buttons provided may enhance
students exploration towards
experiment.
Based on the graph:
The production of palm oil
depends on the population of
rats and owls.
Simulation can make students
more excited to conduct any
experiments.
4. Abnormal graph
Owls population
Population of owls increase slightly at the
beginning
It started to decrease drastically to zero after a
few years
Rats population
Very low at first
After few years, it started to increase gradually
(because of no predators)
Palm oil plants
Slowly increasing throughout the year
Started to decrease due to increasing number of
rats
There was equilibrium among these three variables.
To cope with this situation, we can implement
biological method (biological control).
5. Abnormal graph
The manipulating variable only for owl
population
From the graph , student can predict
the population of owl will affect the
population of rat to be increase.
The graph can be interpreted by the
student and can explore the trend
Rate population of owl increase the
rate population of rat decrease while if
the rate of rat increase, the rate of owl
will increase too
