| Description: |
| Models and simulations simplify and illustrate complex and abstract phenomena and processes. They can be used in virtual labs when it is impossible, too difficult, too expensive or immoral (in the case of animal studies) to conduct a real-life experiment. Models and simulation can be applied in various fields such as finance, mathematics. physics, meteorology, biology, social sciences etc. When using manipulable variables, learners can explore how the modeled phenomenon behaves in various situations, including extreme situations. One advantage of computer-based models is that they enable learners to explore the effect of each variable on a system by manipulating one variable at a time and holding others still. |

| Tips (Challenges, Limitations, Tradeoffs, Pitfalls): |
| There are some limitations to this principle, such as that they might enable students to create extreme situations that are not possible by nature. Although such situations might provide powerful insights, students should be provided with information about the limits of a model. Another limitation is that even though virtual labs and simulations can save time and money, and create a controlled environment, sometimes seeing the actual procedures in real life can have a greater impact on students. |
