Arvind Jaju,
The best way to select a topic is to choose the one that interests you the most. Out of your choices, which one is the most interesting to you. Once this is done, let me know which topic you pick, and then we will narrow it down to a good project, OK?
Good Luck

Hi,
Thanks for your replies...
We have been told to make working models only.
Last year I had made a project on Pollution and Effect to Ozone Layer, which won the first prize.
Of the given topics, I am most interested in working on
# Energy and its Conservation
and
# Educational Technology & Mathematical Modelling
IS A WORKING MODEL POSSIBLE FOR "Educational Technology & Mathematical Modelling" Project.
Waiting for your reply..

Working Models

Arvin Jajoo,
When you say "working models," do you mean models that move, or modles that accurately represent the concept being illustrated? Either way, there are numerous things that you can do with mathematics. The entire fields of Geometry, Coordinate Algebra, and Calculus all deal with the shapes and curves of various objects. If you are good at math, a topic in one of these areas is for you!

Yes...
It also means about models which can be implemented in real life and benefitted from.
For e.g. someone last year made magnetic paint. Noting was moving but the magnetic paint was working.
Please suggest me some topic on "Educational Technology & Mathematical Modelling". I am chosing this topic because I am good at maths and also that many less number of people will be working towards it.
Regards,
Waiting for your reply.

Arvind Jajoo,
If you don't mind me asking, but what math are you currently taking. I need to know how advanced your math skills are before going further. Also, what grade are you in?
Grade

What is Educational Technology?
What is Mathematical Modelling?
The world consists of a large number of natural as well as man-made systems, invariably both complex and dynamic. Our knowledge about these systems depends on advances made in science and technology. It is necessary to divide such systems into several subsystems to facilitate their study. The prediction of the behavior of the system on the basis of the characteristics of the subsystems is generally made using the systems approach.
Mathematical modelling plays a very important role in the entire process as it helps to analyse various variables and parameters of the system/subsystem under consideration, both in quantitative and qualitative terms. The corresponding mathematical model predicts the future behavior of the system under consideration. Recent developments in mathematical sciences and computers have led to improved modelling and understanding of situations in all areas of human activity including not only engineering, medicine, biology, ecology, environment, geology, oceanography but in economics and a variety of other social sciences. Modelling and computer simulation have become valuable tools for example, in industry for improving the manufacturing process; in ecological and environmental sciences for analysis of bidiversity and prediction of weather, ocean circulation, effects of deforestation, global warming, climatic change, storm surges etc. in social sciences for developing strategies for sustainable development and understanding social and economic change, etc.
I am not getting how I will make a working model... ?
All I got from google.com was

And I am not good at Biology..

Arvind Jajoo,
What does ninth grade math consist of? Is it pre=algebra, algebra, geometry, algebra two, trigonometry, etc? If you are in high enough math, you can make a model using a tyep of mathematics called linear programming. Have you ever heard of the term? Basically, linear programming is a way to figure out how you can maximize production, minimize cost, and numerous other things. Linear programming is very applicable, and would be very useful in making a working model. (In other words, a you would design a set of equations to set parameters that would help describe something in the real world!)
How do I relate it in Educational technology

How can I use it in Educational technology..?
What you are saying is using it for computational measures...

Hi,
My teacher liked the idea, THANKS..
Could I now guide me to wards Linear Programming.

Arvind,
Check out this website:
http://en.wikipedia.org/wiki/Linear_Programming
Also, ask your teacher for a textbook that talks about linear programming. If you need help, ask him.
If you need to encorporate Educational Technology, you might develop a scenario that deals with your school. Since linear programming deals with setting constraints on a function, it may be useful for using this scenario. Once you find out a little more about lnear programming, we will discuss how to formulate the function. and establish the constraints.
Good Luck!
How do I Encorporate Educational Technology

Hi,
I have understood the basics of Linear Programming.
Guide me on how do I Encorporate Educational Technology in it..

Linear Programming and Educational Technolgy

Arvind,
You can incorpate educational technology by using a scenario that involves your school. Lets look at an simple example:
A government grant has just given your school $400,000.00 american dollars to buy new textbooks. Your school decides it wants to get new math textbooks and new science textbooks. The math textbooks are $65.50 US dollars and the science textbooks are $78.00 US dollars. However, no more than 500 new books can be purcahsed. A $5.00 US dollar shipping charge is added to the price of every 10 books. How many of each textbook should your school buy in order to get the most books, thereby helping the most students?
As you can see, this problem uses mathematical modeling to help your school determine the best way to spend its money. By maximizing the amount of texts that your school gets, you are helping your school be better by allowing the greatest benefit to the students. You could also do a similiar problem purchasing computers or any other things. If you ask me, this is an excellent example of using mathematical modeling to benefit education.
Anyhow, you are more than welcome to use the above example for your project. You are also more than welcome to come up with your own scenario. No matter what you decide to do, I will always be here to help. I am more than willing to go over how to solve the problem with you, or check your math, if you wish. If you need help, just ask!
Good Luck!

I want the example to enhance the teaching and learning process via mathematical modelling, and then it will be a perfect blend of educational technology and mathematical modelling.
My Project first talks about Educational Technology.
Its types viz Active Learning & eLearning.
Then I speak about Mathematical Modelling & I say that I will be using Linear Programming (LPP) to explain how learning and teaching process can be improved by using mathematical modelling i.e. by using LPP.
The example you gave I think will not suit my scenario.
I hope you are getting what I am saying.
Please Guide...

Arvind,
I think I understand what you are getting at. You want to use LP to show whether eLearning or active learning is a better process for teaching. This IS doable. Of course, you will only be able to look at this from a fiscal standpoint. So, first you need to write your constraints. Take into account the budget of your school, the cost of having teacher, the cost of textbooks, the cost of internet access, the cost of eLearning services, etc. You may need to use a 3D plane as opposed to a coordinate graph, but we'll try to keep it 2D. Since the goal of your LP will be to determine which method of learning is more cost effective, the function that you maximize will need to describe the fiscal impact of each. You may have to use two separate equations, one representing active learning andone representing eLearning, and then using the one with the largest maximum as the most cost-effective.
Do you follow me? I will try to set up a sample problem and post it, but I may not have it done for a while.
If you need help, just ask!
Good Luck!

For students below VI grade I will not use the example of LP. I will use the example of Distance = Speed x Time.
Hence I don't want to get into elearning vs mathematical modelling.
All i want to do is to introduce to the ppl the concept of Mathematical Modelling in Educational Technology. I guess that I am doing with LP.
Now I want to pick up a everday example or an example through which they can swallow very easily the benefits of matheatical modeling.

Arvind,
Linear Programming is NOT simple. You can not "dumb it down" for lower students. If however, you do want a simple question, go to your math teacher and ask to see the Algebra II book. Look up linear programming, and use a problem from the book. Thats about as simple as you can get.!
You cannot use the same problem for distance=speedXtime as you do for LP. It is just not possible.
