Sharing of EJS Sims to the JC Track Physics STs at NIE

Thanks to Darren who invited me to share :)
Sharing of EJS Sims to the JC Track Physics STs at NIE 



Title: Sharing of EJS Sims to the JC Track Physics STs
Venue: NIE7-B1-22
Date:Thu, 10 Oct 2013
Time: 0930 to 1100

Title: Java Simulation Design for Teaching and Learning NRF2011- eduLab 001

Abstract:

The Open Source Physics community using Easy Java Simulation (Esquembre, 2004) has created hundreds of computer models (simulations) that could be finer customized (Wee & Mak, 2009) to the Singapore syllabus for more targeted productive activities.

We will share the 9 computer models’ features for guided inquiry learning and existing worksheets designed by teachers in River Valley High School, Yishun Junior College, Innova Junior College, Anderson Junior College, Serangoon Junior College .

Our work include:
eduLab project: NRF2011-EDU001-EL001 Java Simulation Design for Teaching and Learning
2012 MOE Innergy (HQ) GOLD Award “Gravity-Physics by Inquiry”.
A small library can be found here http://weelookang.blogspot.sg/p/physics-applets-virtual-lab.html


all simulations and worksheets
you can download them individually in the picture captions links.

Objectives:
By the end of the session, participants should be able to:
(1) aware of the features and possible usage of the 9 computer models

the using new feature with new wave form to allow counting of number of wavelength with RVHS tat leong in ripple tank sim plus some bug fixes. made dt smaller 0.01 for smooth graph
Ripple Tank Model (Wee, Duffy, Aguirregabiria, Hwang & Lee, 2012) with simplified physics equations modeled, realistic 2D and 3D (shown) visualizations, hints and scientific measurement tools for inquiry activities and data gathering for inquiry learning
