Title: Sharing of EJS Sims to the JC Track Physics STs
Venue: NIE7-B1-22

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
