title:  Computer Modeling Pedagogy using Tracker
event:7th Physics IPSG Sharing Session for A-level Physics educators
date:  21 Jan 2015 (Wed) from
time: 2:30 pm – 5:30 pm


This 60 minutes hands-on workshop (extension of 3rd IPSG: Learning physics of sports science through video analysis and modelling by Lee Tat Leong and Wee Loo Kang Lawrence) aims to emphasis the Computer Modeling Pedagogy (Wee, Chew, Goh, Tan, & Lee, 2012) using Tracker as an appropriate method to understand Dynamics, Circular and Oscillations topics. The model building process using Tracker's Dynamics Particle Model in Cartesian and Polar Coordinate Systems allows students to iteratively come up with suitable Physics (recommended with nested if statements) computer models (Brown, 2007, 2008, 2009, 2012; Christian & Esquembre, 2012) to represent their video analysis.

The following models will be covered:
  1. Dynamics: roller blading down a slope model (video by KoayTzeMin RGS sec3 student mentored by Leong Tze Kwang.
    1. variables used: g = 9,81, k =0.708
    2. initial values: vx = 1.384
    3. fx' = g*sin(5.7*pi/180)-k*vx
    4. fy' = 0
  2. Circular: Uniform Circular Motion Break Model (video by Lim Jit Ning HCI)
    1. model: initial values θ = 25 deg, ω = 615 
    2. fr = if(t<2.795,-ω*ω*r,0)
    3. fθ = 0
  3. Oscillations: Simple Harmonic Motion with Collision Model (video by pohhuiyinaomi RGS sec3 student mentored by Leong Tze Kwang)
    1. variables used: g = 9.81, F=230
    2. initial values: t = 2.345, r = 0.3737, θ= -113º
    3. fr = -ω*ω*r
    4. fθ = if(t<9.581,-m*g*cos(θ),if(t<9.586,F-m*g*cos(θ),-m*g*cos(θ)))
All models and resources are downloadable and editable, licensed creative commons attribution for the benefit of all, directly on Tracker itself as a Shared Library (Wee, 2014).

We are pleased to share with you that the Physics IPSG committee will be holding the 7th Physics IPSG Sharing Session for A-level Physics educators on 21 Jan 2015 (Wed) from 2:30 pm – 5:30 pm at Nanyang Junior College. The objective of the sharing session is for the A-level Physics teachers to get together to network and share their teaching experiences and good practices.

As in the previous years, there will be concurrent sharing sessions. On behalf of the IPSG committee, we would like to invite you to share during the concurrent sharing sessions. Each presentation/workshop should be 30 min or 60 min long, including any Q&A sessions. The categories of sharing could be in the following 5 areas:
  1. Hands-On / Experiments
  2. Enrichment activities
  3. Demonstrations
  4. Teaching Strategies
  5. Others
Abstracts of presentations should be submitted via the google form at http://tinyurl.com/7th-PhysicsIPSG-submission by 11 November 2014 (Tuesday).

Abstracts from past IPSG Sharing have been uploaded onto the Physics IPSG website and can be found via this link:http://physicsipsg.wordpress.com/archives/ for your reference.

More details about the event will be given to you at a later date upon the receipt of all abstracts.

Please feel free to forward this email to any of your colleagues from ETD who may have interesting ideas/ projects to share. J
Thank you!
On behalf of Physics IPSG committee
