time: 1500-1730
please add on to the agenda for 9th Java Sims meeting eduLab.
- any questions from previous meetings http://weelookang.blogspot.sg/2013/05/8th-java-sims-meeting.html
- MPTL18 sharing by jimmy ee-peow and lookang
- extension approval by ai phing, tat leong and lookang
- approved until Dec 2014
- action plan Outline of implementation plans (including schedules)
- Quarter 2014: Give away lesson packages and implementation guide(s) to all JCs
- Q2: support interested JC in their implementation of their own revised lesson packages (teaching cycle topic in most JC could be collision carts)
- Q3: support interested JC in their implementation of their own revised lesson packages (packages (teaching cycle topic in most JC could be gravity)
- MPTL19-GiREP http://www.unipa.it/girep2014/ conference
- Q4: professional development workshop and public of Invited scholars ( Full professor Wolfgang Christian, Founder of Open Source Physics and Associate Professor Francisco Esquembre Creator of Easy Java Simulation.) 4Q is suggested by invited Professors
