Open Source Physics
Open Source Physics (Brown, 2012; Christian, 2010; Esquembre, 2012; Hwang,
2010) empowers teachers and students to create and use these free tools with
the associated intellectual property rights given to customise (Wee & Mak,
2009) the computer models/tools to suit their teaching and learning needs. Open
Source Physics (OSP) focuses on design of computer models, such as Easy Java
Simulations (EJS) and the use of video modeling and analysis (Tracker). They
allow students to investigate, explore and analyse data which is either real or
simulated. The OSP approach helps users overcome barriers in creating, using
and scaling up meaningful ICT use in education. In Singapore, teachers and
students have created or customised existing computer models to design and
re-purpose EJS models to suit their context and learning needs. Tracker tools
allow students to analyse different aspects of a physics phenomena to deepen
their understanding of abstract physics concepts. Using Tracker, students
record the motion of objects and create their own models to test their ideas in
the study of kinematics. Essentially, the two main pedagogical approaches
(Figure 1) used in OSP are: Guided Inquiry investigating modeled phenomena(EJS)
video analysis (Tracker) Constructionism learning by making new models(EJS)

Open Educational Resources from Performance Task using Video Analysis and Modeling - Tracker and K12 science education framework
This invited paper discusses why Physics performance task by grade 9 students
in Singapore is worth participating in for two reasons; 1) the video analysis
and modeling are open access, licensed creative commons attribution for
advancing open educational resources in the world and 2) allows students to be
like physicists, where the K12 science education framework is adopted. Personal
reflections on how physics education can be made more meaningful in particular
Practice 1: Ask Questions, Practice 2: Use Models and Practice 5: Mathematical
and Computational Thinking using Video Modeling supported by evidence based
data from video analysis. This paper hopes to spur fellow colleagues to look
into open education initiatives such as our Singapore Tracker community open

Creating Electronic Books-Chapters for Computers and Tablets Using Easy Java/JavaScript Simulations, EjsS Modeling Tool
This paper shares my journey (tools used, design principles derived and
modeling pedagogy implemented) when creating electronic books-chapters (epub3
format) for computers and tablets using Easy Java/JavaScript Simulations, (old
name EJS, new EjsS) Modeling Tool. The theory underpinning this work grounded
on learning by doing through dynamic and interactive simulation-models that can
be more easily made sense of instead of the static nature of printed materials.
I started combining related computer models with supporting texts and
illustrations into a coherent chapter, a logical next step towards tighter
support for teachers and students ,developing prototypes electronic chapters on
the topics of Simple Harmonic Motion and Gravity customized for the
Singapore-Cambridge General Certificate of Education Advanced Level (A-level).
I aim to inspire more educators to create interactive and open educational
resources for the benefit of all. Prototypes:

Physics Educators as Designers of Simulation using Easy Java Simulation (Ejs)
To deepen the professional practice of physics educators, I seek to highlight
the Open Source Physics (OSP) and Easy Java Simulation (Ejs or EJS) community
of educators that engage, enable and empower teachers as learners so that we
can be leaders in our teaching practice. I learned through Web 2 online
collaborative means to develop simulations together with reputable physicists
through the open source digital library. By examining the open source codes of
the simulation through the Ejs toolkit, I was able to examine and make sense of
the physics from the computational models created by practicing physicists. I
will share some of the simulations that I have remixed from existing library of
simulations models into suitable learning environments for inquiry of physics.

Physics Educators as Designers of Simulation using Easy Java Simulation (Ejs) Part 2*
To deepen do-it-yourself (DIY) technology in the physics classroom, we seek
to highlight the Open Source Physics (OSP) community of educators that engage,
enable and empower teachers as learners so that we create DIY technology
tools-simulation for inquiry learning. We learn through Web 2 online
collaborative means to develop simulations together with reputable physicists
through the open source digital library. By examining the open source codes of
the simulation through the Easy Java Simulation (EJS) toolkit, we are able make
sense of the physics from the computational models created by practicing
physicists. We will share newer (2010-present) simulations that we have remixed
from existing library of simulations models into suitable learning environments
for inquiry of physics. We hope other teachers would find these simulations
useful and remix them that suit their own context and contribute back to
benefit all humankind, becoming citizens for the world. Abstract Footnotes:

A Case Study of Open Source Physics (OSP) Learning Community (LC)
This paper examined how the Open Source Physics at Singapore learning
community of teachers, loosing connected as creators, adapters and users, is
projected to be able to self sustain, through the 3Ps scaling-up framework, of
Product, Process and People. References were made to another project called
WiMVT Web-based iMVT and now known as Collaborative Science Inquiry (CSI), a
formalize Ministry of Education (MOE) effort to spread out good practices.
Having a vision, reason, and passion-emotion are factors that the authors argue
can fuel and propel the spreading of those good teaching and learning
practices.Comment: 5 pages, 2 figure
Use of Blended Approach in the Learning of Electromagnetic Induction
This paper traces the importance of pedagogical content knowledge in the
digital age to prepare today students for the 21st century. It highlights the
need for ICT-based pedagogical models that are grounded in both the learning
theories of constructivism and connectivism. One such suitable ICT-based
pedagogical model is the TSOI Hybrid Learning Model. By means of a physics
blended learning exemplar based on the TSOI Hybrid Learning Model, this paper
argues for the use of blended learning approach as the way forward for 21st
century teaching.Comment: 11 pages, 6 figures, Science Teachers' Association of Western

Using the knowledge of penumbra with a trick simulation
The study is about a basic shadow experiment, which was enriched with a
simulation to understand the reasoning of participants when we use a trick. Two
light sources create an umbra and penumbra behind the objects. With this
experiment, we asked what would happen when the penumbras interact. Most of the
participants predicted the correct solution, that there should be an umbra.
Some of the participants choose wrong alternative, and explained in terms of
the structure of penumbra.Comment: 3 pages, 3 figures, Latin-American Journal of Physics Education, ISSN

Geostationary Earth Orbit Satellite Model using Easy Java Simulation
We develop an Easy Java Simulation (EJS) model for students to visualize
geostationary orbits near Earth, modeled using Java 3D implementation of the
EJS 3D library. The simplified physics model is described and simulated using
simple constant angular velocity equation. Four computer model design ideas
such as 1) simple and realistic 3D view and associated learning to real world,
2) comparative visualization of permanent geostationary satellite 3) examples
of non-geostationary orbits of different 3-1) rotation sense, 3-2) periods,
3-3) planes and 4) incorrect physics model for conceptual discourse are
discussed. General feedback from the students has been relatively positive, and
we hope teachers will find the computer model useful in their own classes. 2015

Open Source Energy Simulation for Elementary School
With the interactivity and multiple representation features, computer
simulations lend itself to the guided inquiry learning. However, these
simulations are usually designed for post-elementary students. Thus, the aim of
this study is to investigate how the use of guided inquiry approach with
customized energy simulation can improve students' understanding of this topic.
In this ongoing research, the case study is adopted. In the first phase of the
study, we have modified open source energy simulation based on principles for
reducing extraneous processing, existing energy simulation and guided inquiry
approach. The modified simulation is sent to teachers for evaluation and the
feedback is encouraging. In the next phase of the study, the guided inquiry
lesson package involving the energy simulation would be designed and deployed
in an elementary classroom. Multiple data sources would be collected to seek a
deeper understanding on how this learning package can possibly impact students'
understanding of the physics concepts.Comment: Proceedings of the 20th International Conference on Computers in
