2. STELLA SOFTWARE
• To prove the effectiveness of simulation and
modelling in teaching and learning process
• STELLA offers a practical way to dynamically visualize
and communicate how complex systems and ideas
really works
• STELLA is used to simulate a system over time
- Students may predict what will happen next for the
experiment
- Trigger students to think more about what will happen
next in the experiment if they increased the data

3. Graph 1 : 0 size of time lynx harvest
- The graph show straight horizontal line between hares and also lynx
- The system is still maintain as there are no threaten on hares
- The ecosystem is still at equilibrium

4. Graph 2 : 300 size of time lynx harvest
- The graph became unstable
- Shortage of prey means that the predator has to compete each other for food
- At certain time the number of hare also decrease
- When the number of predator increase, the number of prey also increase

5. Graph 3 : 700 size of time lynx harvest
- The graph became more unstable
- Shortage of prey means that the predator has to compete each other for food
- At certain time the number of hare also decrease
- When the number of predator increase, the number of prey also increase

6. ADVANTAGES & DISADVANTAGES
1) Offers the opportunity to
experiment with phenomena
or event
2) Give the student more
feeling for reality in some
abstract fields of learning
3) Bonus for the teacher to
explain a difficult
interrelationship
1) Simulation error
2) It can be quite expensive
to build a simulation model

7. CONCLUSION
• STELLA have the potential to enhance the way
of the teaching and the students learning
• It is suitable for teacher to use it in school
• They allow teachers to bring even the most
abstract concepts of life for students
