6th IPSG A-level Physics

6th IPSG A-level Physics Call for Adoption: Java Simulation Design for Teaching and Learning NRF2011-EDU001-EL001
Title: 6th IPSG  A-level Physics
Date: 22 Jan 2014 (Wed) 
Time: 2:00 pm – 5:00 pm 
Venue: Innova Junior College.
Objective: The objective of the sharing session is for JC physics teachers to get together to network and share their teaching experiences and good practices. In short, it is a platform for teachers to get together in an informal setting to talk about JC physics teaching .
Format: Each presentation/ workshop should be 30 min or 60 min long, including any Q&A sessions. Categories:
  1. Hands-On
  2. Experiments
  3. Enrichment Activities
  4. Demonstrations
  5. Teaching Strategies
  6. Assessment
  7. Others

Abstracts from the 5th IPSG sharings held this year have been uploaded onto the Physics IPSG website and can be found via this link:

Title: Call for Adoption: Java Simulation Design for Teaching and Learning NRF2011-EDU001-EL001

We have develop, prototype and test-bed Open Source Physics computer models and complete lesson packages, that are realistic and accurate for the benefit of all Grade 11 and 12 students in the world, freely downloadable on to support pedagogically sound practices such as virtual laboratory, argument real laboratory and even on-line flipped classes as announced by Minister Heng recently as a student on-line learning space. This sessions aims to share the body of knowledge of our experiences in using these simulations in River Valley High, Yishun JC, Serangoon JC, Innova JC and Anderson JC and network with participants to allow them to bring our lesson packages (Collision Carts Model -Best School Research Paper Winner 5th Design Pedagogy Conference, Ripple Tank Model, Magnet and Solenoid Model, 4 Gravity Models - MOEHQ Innergy Gold award 2012, Simple Wave Model etc) and use them more effectively for a student centric education. 
Our principal findings suggests skilful teaching with these computer models can increase interactive engagement, better visualization and sense making, to be key to allowing students to be like 'scientists', ask question, collect data, evaluate, elaborate and explain based on evidences from the computer models and the real world.

MIN = xsource
MAX =Math.sqrt((xpoint-xsource)*(xpoint-xsource)+(ypoint-ysource)*(ypoint-ysource))+xsource
X(x,t)= "xsource+sign*((x-xsource)*cs-0.1*A1*Math.cos(omega*t-k*(x-xsource))*sc)"
Y(x,t) ="ysource+sign*((x-xsource)*sc+0.1*A1*Math.cos(omega*t-k*(x-xsource))*cs)"
angle = Math.atan((ypoint-ysource)/(xpoint-xsource));
cs=Math.cos(angle); / /lookang & FKH
sc=Math.sin(angle);//lookang & FKH
cs2=Math.cos(angle2); // use to rotate to universal axes
sc2=Math.sin(angle2); // use to rotate to universal axes
using if ((xsourcexpoint)){ sign = -1;  } // fix another bug where the curve flips
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
added (1) autoscale x axis false, (2) -T/8 button (3) blue color for wave 2 for greater contrast on the projector screen thanks to joshua yeo.
