Modelling & Simulation
Model is a representation of an object, a system or an idea.
Two types:
1. Physical (Scale models, prototype plants)
2. Mathematicals (Analytical queuing models, simulations, linear program)
What is modelling?
Simulation is an operation of a model which is a representative of that system.
This model is amenable to manipulation which would be impossible, too expensive or too impractical to perform on the system which it portrays.
Simulation is used in designing and analyzing manufacturing systems. Simulations can be used in chemistry, geographic and others.
Steps in Simulation & Model Building
Two types:
1. Physical (Scale models, prototype plants)
2. Mathematicals (Analytical queuing models, simulations, linear program)
- Analytical solution
- Simulation
What is modelling?
- Modelling is a way of thinking and reasoning about systems.

Steps in Simulation & Model Building
- Define an achievable goal
- Put together a complete mix of skills on the team
- Involve the end-user
- Choose the appropriate simulation tools
- Model the appropriate level (s) of detail
- Start early to collect the necessary input data
- Provide adequate and on-going documentation
- Develop a plan for adequate model verification
- Develop a plan for model validation
- Develop a plan for statistical output analysis
Interactive Whiteboard (IWB)
- Easy to communicate
- Take time to explore
- Expensive
- Turn computer into an powerful tool for teaching, collaborating and presenting
- Touch screen
- Interactive
- Motivate students
- Quick and easy access to information
- Safe search for searching the internet
- Video conferencing
Effectiveness of IWB in schools:
- Making notes in digital link
- saving notes for later review by using e-mail, the web or print
- Viewing websites
- Demonstrating
Research on Overall Use and Effectiveness
- Increase pupil engagement
- Motivation
- Enjoyment
- Potentially leading to improvements in individual student learning ability
- Impact whole-class
- Extend the range of style of teaching
- Explore new ways of creative teaching.
Disadvantages of IWB in schools:
- Ineffective and incorrect resources
- Searched internet content not suitable for students vision
- Used as just a projector
- Cost of downloading website
- Need to either type into the browser bar using the keyboard connection/ use the on-screen keyboard which is small and hard to use if not calibrated right.
PBL
1. Create a Problem
4. Presenting
- Find a real life situation with multiple solutions that interest the students.
- Organize the students into teams.
- Students list known facts
- List unknown
- Research unknown
- Students must model the situations to test the theories.
- Students generate possible solutions.
4. Presenting
- Students select the solution that best fits.
- Students present their solution and methods.
Disadvantages usage of ICT in teaching and learning
Disadvantages usage of ICT in teaching and learning :
1. Some people may not like working on computer system.
2. Reduced practice of graphing skills.
3. Students may not relate science concept to microscopic and symbolic system and representations.
4. Loss of conventional methods of data collection.
5. Increased work load of teachers.
