EJSS Gravity Field Visualization Model

EJSS Gravity Field Visualization Model
by lookang (repurpose for gravity) and jiunwei(original author electric field visualizer).
thanks +Jiun Wei Chia for sharing his codes :)

gravitational field line (vectors) of Earth when seen from outer space, added test mass to plot field lines by jiunwei
the magnitude of field lines are now proportional to $ \frac{1}{r^{2}} $ where r is the distance of test mass to Mass creating the field.

NRF2011-EDU001-EL001 EduLab Project Scaling-Up Reflections on Using Open Source Physics

Abstract: 

eduLab (MOE, 2012b) is a key programme under the third MasterPlan for ICT in Education (mp3) where teachers with good ideas for an ICT-enhanced lesson or curriculum (learning with computer models through inquiry, example PhET (PhET, 2011) can come together to collaborate. eduLab aims to support teachers to develop, prototype and test-bed their lesson ideas (journey in 2012-2014) while ensuring that the results, in the form of complete lesson packages (see http://edulab.moe.edu.sg/edulab-programmes/existing-projects third project) , are scalable across schools to benefit the wider teaching community. Our models and lessons are downloadable here http://weelookang.blogspot.sg/2013/03/moe-excel-fest-2013-scaling.html We have collaborated with namely Professor Francisco Esquembre, Professor Fu-Kwun Hwang and Wolfgang Christian and created Open Source Computer Models on the topic of 1 Dimensional Collision (Loo Kang Wee, 2012b), Falling Magnet in Coil, Ripple Tank (Duffy, 2010; G. H. Goh et al., 2012; Ong, Ng, Goh, & Wee, 2012; Ong, Ng, Teo, et al., 2012; Loo Kang Wee, Duffy, Aguirregabiria, & Hwang, 2012), Superposition Waves, 2 Mass Gravity, Earth-Moon Gravity, Kepler's Solar System and Geostationary Orbit (J. Goh & Wee, 2011; Loo Kang Wee, 2012a; Loo Kang Wee & Esquembre, 2010; Loo Kang Wee & Goh, 2013) for enriching interactive engagement (Christian & Belloni, 2000; Hake, 1998) previously lacking in our teaching practices, but we argue is essential for deepening learning (L.K. Wee & Lye, 2012) by doing. We hope to share some of the learning points from ideas (researchers Francisco Fu-Kwun and Wolfgang) to practice (teachers in RVHS, YJC, IJC, AJC and SRJC) supported by specialist (ETD), contextualized and made possible through this edulab funding initiative by National Research Fund, managed by National Institute of Education (NIE) and Ministry of Education, Singapore.

Comments from Reviewers: 

With the third MasterPlan for ICT in Education (mp3) as the context, this paper is a praiseworthy collaboration by a community of like-minded and passionate physics educators, locally and abroad to promote the effective use of ICT in physics education in the form of ICT-enhanced lesson or curriculum (learning with computer models through inquiry, example PhET). The eduLab's aim to support teachers to develop, prototype and test-bed teachers' lesson ideas while ensuring that the results, in the form of complete lesson packages are scalable across schools to benefit the wider learning community is a worthy innovation effort to propagate best practices in a systematic and systemic approach.

good ideas to share when i lead a new team.

good ideas to share when one lead a new team.

Leadership is motivating and organizing a group towards a common goal.

Brand

signature product (open and free technology of education?) and service (remixing and contributing?)

Culture 

Hard to nail but can be felt and influential on the way we behave (open culture)
open flat hierarchy debate but support after meeting (get enough hierarchy to get the job done and not excessive until is burdens the team)

Teamwork

others divisions as siblings
One organisation
Collaborate with cousins
Benefit students, teachers, myself and something bigger.

Keep

What do we keep doing

Improve

What do we improve on

Stop

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

Abstract:

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). Send your Tracker project *.trz to weelookang@gmail.com for inclusion into the Tracker's Singapore Digital Library collection http://iwant2study.org/lookangejss/.

Invitation: 

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!
Regards,
On behalf of Physics IPSG committee
