Hi

I am learning Easy Java Simulation.

I created a Simple stopwatch simulation. Need your all suggestion.

looks awesome!
what is the aim of your simulation?

perhaps you can add the digital numbers for students to check their understanding
u can refer to this by Fu-Kwun Hwang http://www.phy.ntnu.edu.tw/ntnujava/index.php?topic=990.0

I created this stopwatch simulation looks like a real stopwatch. If we display digital numbers students cant not learn how to read stopwatch. Instead of displaying numbers, if we let student to note the seconds hand and minutes hand they can learn much more (thats my thought). The main aim of the simulation is "resuable stopwatch". If someone need stopwatch in their simulation, then there is no need of writing code. They just copy and paste this stopwatch code. This is portable stopwatch.

My future work:

I am going to reduce computational cost. Currently, stopwatch 300 second hand ticks creating by for loop. So it takes more computation. And fixed relation also takes more computation. 

And, I am going to implement magnifier. If suppose, student want to see exact ticks where the hands stops the magnifier will help. So I need your all helps.

u can make a check box to select the hints and answers. example http://www.phy.ntnu.edu.tw/ntnujava/index.php?topic=684.0
u can add a text field for student to key in their inputs to check against the computer answer. example http://www.phy.ntnu.edu.tw/ntnujava/index.php?topic=2262.0

u have good idea to share simulation, that is what Ejs can do, perhaps u like to add your name to the Ejs file so that when people use your work, their can leave your name there as credits of the stop-watch sim.


maybe u can refer to real photo http://onyxinvesting.com/2011/06/nice-last-minute-trade-on-entropic/

to increase the realism.

looking forward to your future simulations!

The following is a stop watch with magnifier. It is only available when time is not zero.
A new yellow circle will be shown when magnifier checkbox is checked.
You can drag the yellow circle (center) to change the magnified area.
The slider can be used to change the ratio for magnification.
Enjoy it!

i made some slight remix to the simulation on stop watch by dhasthagheer, added on by Fu-Kwun Hwang, and now slightly remixed by lookang.
i will post on my board as well and record the changes made:)
