made changes

  1. added TE
  2. added legend for the color
  3. added ref. PE = 0 line GREEN  (discussion with ravi, MTT)
  4. noted the decrease in KE after each collision with the floor ( discussion with boon leong)
  5. made ref PE = 0 to coincide with C.G. of the ball
  6. made ball drawing 35x35 pixel smaller to reflect the floor at y= yground +sizey/2
  7. made _pause() if ball y lower than the floor

Using Good Tools or Ideas in Teaching

I also brought ezcast to try it out.

thanks Elaine Chua for sharing and also Sze Yee for loaning me a copy of her ezcast.





Networked Learning Communities

Another example of another physics teacher who believes in students' abilities means going all out to engage them through hands-on toy making process. Thanks to Nazir Amir 

 I also believe students needs interactive engagement pedagogy to enjoy what they do in schooling.

Thanks to so many great lead physics teachers in this Singapore eco system.



Belief in One Another

Awesome teacher. Thank you for inspiring all of us. — with Yap Boon Chien.
Well done ETD and MOE for sharing more videos like this to shape the world with choose to believe in.

Synopsis
Open Source Interactive Resources for Physics
Wee Loo Kang Lawrence
The Singapore Open Source Physics community has matured over the past decade with the members developing and contributing 100+ Computer models using Easy Java Simulation and Easy JavaScript Simulation, and also 100+ Tracker models using Tracker, a video analysis and modelling tool available. These resources run on Windows, Mac OS and Linux and of particularly interest are the new EJSS models that Android, iOS devices through the browser or the EJSS reader app (Play store and App store respectively).
 



when you are motivated, you can and will do anything :) Power to the common people.

Event: Brown Bag - In Time, In Tune Lunch Time Session (Science)
Date: 25 September 2014
Venue: MOE HQ B3-2
Title: Singapore Digital Library - Open Source Physics.

Legally through professional network learning with the Open Source Physics academics community, I have created a suite of interactive resources, licensed creative commons attribution suitable for student’s experimentation for experiential learning to be use, remixed and re-distributed under compatible licences.
  1. 100+ Computer models in Easy Java Simulation (EJS) and Easy JavaScript Simulation (EJSS), authoring tool, particularly impactful is the new EJSS models that runs on Android, iOS devices through the browser or the EJSS reader app ( Play store and App store respectively)
  2. 100+ Tracker models in Tracker, video analysis and modelling tool, on Windows, MacOSX and Linux requiring installation and Java runtime.
Through excellent service to teachers and students using innovating ideas possible through open educational resources, I am thankful for the many Public Service (PS) and Ministry of Education (MOE) awards. There is much Singapore education service can gain through participation in such a meaningful mission to be the best for the world, not just best in the world.

We have extended the successful Easy Java Simulations (EJS) authoring tool <www.um.es/fem/EjsWiki> to help Physics instructors create simulation of Physics phenomena that run on a variety of platforms. These simulations can be used for illustrating physic concepts during in-lecture demonstrations, or to promote thinking-provoking student activities. The simulations created with this new version of EJS can run on any HTML5+Javascript enabled device, which includes virtually any computer and mobile device. We have also created a Reader App that runs on Android and iOS tablets to help teachers and students collect and organize their simulations. Finally, the Reader connects on-line with the US-NSF sponsored comPADRE digital library, which hosts a growing number of simulations for Physics teaching and learning.
Over the past dozen years the Physlet and Open Source Physics (OSP) projects have produced some of the most widely used computer-based curricular materials for the teaching of introductory and advanced physics courses. These materials are based on Java applets called Physlets and on new OSP programs and authoring tools. This session describes how we use these materials in the Davidson curriculum to motivate and engage students in computational physics modeling. In addition to learning to program, students are required to write and communicate, to develop their graphical design skills, and to apply mathematical reasoning to complex problems. We will demonstrate how physics can be taught by modeling, and how this approach helps to deepen the understanding of the underlying physical principles while supporting computational thinking. Examples are available in the ComPADRE National Science Digital Library: <http://www.compadre.org/OSP/>.

Hi Lawrence,
I will be doing "Flipped classroom" for my Pure Physics class next year, so I am converting the current textbook into a digital one by having students to paste QR codes that link to my teaching videos on their textbooks.
I have looked thru some of your applets and found them very effective in demonstrating certain concepts and theory, particularly the one on Brownian Motion. Hence, I would like to seek your permission to incorporate your applets in the digital textbook mentioned above.
Thanks in advance!

Ming Yeo

Constant Velocity antiphase Model

Constant Velocity antiphase Model

model A weelookang.blogspot.sg 4λ = 0.3383 m, imply λ = 0.0846 m. 4T = 0.533 s, imply T = 0.133 s. therefore v = λ/T = 0.63 m/s
model B 3.5λ = 0.3199, imply λ =0.091 m. 3.5T = (0.533-0.1), imply T =0.124 s. therefore v = λ/T =0.74 m/s

average v = (0.74+0.63)/2  = 0.69 m

Constant Velocity Water Wave 2 Source in Phase Model

Constant Velocity Water Wave 2 Source in Phase Model

L = 0.3127 m = 3 λ. imply  0.104 m= λ
3T = 0.567 s.
Therefore, v = λ/T = 0.104/0.189 = 0.55 m/s
