Example Reflection – Visualization

Challenge & Selection    I have selected this tool since I used it while teaching electromagnetic fields subject. In this subject all  things are imaginary. It is very difficult for students to understand the electromagnetic waves their  behaviour and travel through air. There are different co-ordinate systems Cartesian, cylindrical and  spherical. To understand these systems with just imagination is out of scope. Students don’t know 3D  views. Ray travel etc. With visualization technique students are able to understand in a better way. This  is the ice breaking in this subject.     Application  I have started to find the solution for this. I talked and discussed with senior prof. about this. Then an  idea came in mind to prepare models of these co-ordinate systems. With this students really enjoyed  learning.  To prepare a model I have started searching in the market. Searched if anybody has done this earlier.  But I found nothing. I brought cylinder shape tiffin, cycle spokes as an axis, one cardboard to show an  axis. Similarly for spherical co-ordinate system I purchased a big ball. Prepared a cone from soft board.  In the same way I have started discussion with students for selecting a project. Brain storming of an  idea, preparing drawing on piece of paper and then converting it into a model before actual  implementation.  Thus students are able to check whether the idea is implementable or not.   Any system to understand better its good practice to visualize it and then implement it. May be we  have to develop the model many times till it gives correct result.    For the activity, a class is divided into a group of 3 students. Then certain areas are given to them. On  these areas as per their choice they have to select 3 topics. Prepare a drawing of this idea on a piece of  paper. After drawing all the ideas on paper they will get clear picture of viable idea.  Then one of the idea is selected and finalized. A poster is drawn on big paper. Next step is to list the  material required for preparing a model. Material is purchased from market. Then a model is prepared.  If required objective is satisfied then actual implementation has started.    Insight & Approach    With such exercise students are actually get involved in the activity. Groups have healthy competition  between them. They learnt how to work in the group. Thus inter and intra personnel skills are  developed. Actual society problems students can study and develop a good solution.  Students went to the market find material at different places. So they know how to purchase, how to  deal and talk with the people. So any idea that comes into mind is to be written on a piece of paper first.  Then discuss the viability of that idea thoroughly. Select the best one. Then follow the steps to reach the  final goal.
