Visual presentation – Facilitate better understanding of concepts and process. Instant feed back provided by spreadsheet enables learners to see the effect of changing values. Eg:using spreadsheet and  Graph tools for data handling and analysis, data can be presented in more visual and clear form.

Modeling and simulations for demonstration and prediction- Animation enables teachers to demonstrate experiments and environments that would not otherwise be possible. Simulations  eliminate experimental errors and increase visual impact. Eg : Planetary system.

Interactive education and information resource. -  Models are simulated and explore a wide variety of physical phenomena. Eg : Simulation videos from internet.

(2) Write a short note on role of ICT in mathematics with examples.

Ans. Graphical User Interface – It encourage the learners to explore, make mistakes, see the consequences of their decision and rectify.

Observing Patterns- The ICT enables students to look at sufficient cases of mathematical problems by changing values, observe patterns from the invariance and covariance in the result.

Observing links and connections-  A computer enables to readily link an equation, a table of numbers and graph. The  student realize they are  different representation of same thing. Eg; Geogebra can graph directly from two equation.

Manipulating Diagrams or  graphs dynamically- Using ICT tools helps students to develop the capability  to visualize and generate their own mental image.Eg: Geogebra.

(3) What is modeling? Explain with suitable examples.

Ans- Modeling is a virtual representation of real world systems in the language of mathematical equations. Modeling aim to describe the different aspects of the real systems and their interaction through mathematics. Mathematical equations of a model are translated into computer algorithms the can be treated  and solved by ever powerful computers.

Uses

Model are used to quickly explore new solutions and innovations, that can save time and money in the development and validation phases.

For weather prediction, mathematical model of atmospheric motions are based on well know equations and phenomena.

(4) What is simulation?  Explain with suitable examples.

Ans. Simulation is the process of designing a mathematical model of a real or imagined system and conducting experiments with model. It generally refers to a computerized version of model which is run over time to study the implications of the defined interactions. A simulation bring a model to life and shows how a particular object or phenomenon is likely to behave. Simulation proves to be cheaper, safer and faster in all fields of engineering, applied science, medicine, biology, economics and applied mathematics.

Uses

Simulation  techniques are used in the designing new efficient systems. Eg: Car engines, complex air routing plan.

Training simulations thoroughly prepare trainee to react to various situations until the correct response are learned. Eg : Flight simulator or ship simulator model dangerous environments and life threatening situations, so that aircraft pilots or a ship officers are well experienced about an aircraft or ship behavior.

Simulation techniques are used to create computer games for entertainment.
