ICT is used extensively in science, mathematics, modeling and simulation to enhance learning. In science, ICT tools are used to collect data, do presentations and demonstrations, perform predictions, and enable interactive education. In mathematics, ICT provides benefits for effective learning through tools that give feedback, allow observing patterns and links, exploring data, and developing visualizations. Computer modeling and simulation are useful for representing systems without actually creating them, enabling predictions about the future, training without risk, and investigating systems in detail. The key difference is that modeling builds a digital representation of an object, while simulation runs a model to simulate conditions. Both provide benefits like being cost-effective, allowing repeated testing, and improving user efficiency.
