Briefing Document: Open Source Physics and Easy Java Simulation Workshop

1. Overview

This document summarizes a four-day workshop held in Singapore from November 25-28, 2014, focusing on computational modeling in physics education. The workshop was led by two prominent figures in the field: Professor Wolfgang Christian, founder of Open Source Physics (OSP), and Professor Francisco Esquembre, founder of Easy Java Simulations (EJS). The workshop aimed to introduce educators to the OSP project and the EjsS authoring tool, enabling them to create and modify interactive simulations for teaching and learning.

2. Key Themes and Concepts

  • Open Educational Resources (OER) and Open Source Physics (OSP): The workshop centered around the principles of OER, promoting the sharing of educational resources, source code, and curricular materials under a Creative Commons license. The OSP project is a central resource for these materials.
  • "The goal of the Open Source Physics (OSP) project is to make a large number of simulations together with source code and supporting curricular material available for education using the Creative Commons open-source model."
  • Easy Java/JavaScript Simulations (EjsS): EjsS is a code generator tool that allows users to build dynamic simulations without extensive programming knowledge. It's designed to make computational modeling more accessible to educators and students.
  • "EjsS is a code generator that has integrated the OSP code library to add and build interactive user interfaces, draw 2D and 3D objects, numerically solve ordinary differential equations using different algorithms, and represent data using tables and graphs."
  • "EjsS is a free open-source code generator developed to create dynamic simulations using the underlying Java library... While some programming knowledge is assumed, EjsS users are encouraged to focus on modelling rather than on programming."
  • Computational Modeling-Based Pedagogy: The workshop championed the use of computational modeling as an effective teaching approach. This pedagogy moves beyond traditional methods by allowing students to actively construct and explore physics concepts through simulations.
  • "The implementation of a computational modelling-based pedagogy often requires significant effort and computer science knowledge for teachers and students. The Easy Java/JavaScript Simulations modelling and authoring tool minimizes this effort while teaching good computational techniques."
  • Hands-on, Practical Learning: The workshop was structured around a combination of morning lectures and practical sessions, where participants worked on computers and had access to one-on-one consultations. This hands-on approach encouraged exploration and deeper understanding.
  • "This four-day workshop combines morning expositions and practical sessions where participants will work in teams/individually on computers provided by the organizers followed by afternoon one-on-one consultations..."
  • Adaptation and Customization: The workshop encouraged teachers to not only use existing resources but also to adapt and customize them for their specific teaching contexts, including the NRF2011-EDU001-EL001 customized models and worksheets.
  • "This workshop will benefit teachers who as wish to adopt and adapt EjsS material on ComPADRE for their own teaching..."
  • "Participants will study and explore, step by step, important computational and pedagogical examples...to learn how they have been implemented in EjsS, and then modify these examples to add new capabilities."
  • ComPADRE National Science Digital Library: The workshop emphasized the importance of the ComPADRE platform as a repository for OSP resources and a community for sharing and collaboration.
  • "All workshop materials will be made available through the Open Source Physics Collection on the ComPADRE National Science Digital Library."

3. Workshop Structure and Activities

This workshop aims to provide a hands-on bootstrapping experience to the ComPADRE Open Source Physics (OSP) project and the Easy Java/JavaScript Simulations (EjsS) modelling and authoring tool. This four-day workshop combines morning expositions and practical sessions where participants will work in teams/individually on computers provided by the organizers followed by afternoon one-on-one consultations with some references to NRF2011-EDU001-EL001 customized models and worksheets with the workshop leaders. Participants will study and explore, step by step, important computational and pedagogical examples, such as the gravitational N-body and the simple harmonic oscillator models, to learn how they have been implemented in EjsS, and then modify these examples to add new capabilities. 

The goal of the Open Source Physics (OSP) project is to make a large number of simulations together with source code and supporting curricular material available for education using the Creative Commons open-source model. EjsS is a code generator that has integrated the OSP code library to add and build interactive user interfaces, draw 2D and 3D objects, numerically solve ordinary differential equations using different algorithms, and represent data using tables and graphs.

Although there are many computational tools that allow scientists and engineers to create programs, the implementation of a computational modelling-based pedagogy often requires significant effort and computer science knowledge for teachers and students. The Easy Java/JavaScript Simulations modelling and authoring tool minimizes this effort while teaching good computational techniques. EjsS is a free open-source code generator developed to create dynamic simulations using the underlying Java library. EjsS was originally created for interactive learning under the supervision of educators but is well suited for use by researchers to prototype applications and by authors to develop and distribute Java-based and more recently Javascript-based curricular materials. While some programming knowledge is assumed, EjsS users are encouraged to focus on modelling rather than on programming. 

This workshop will benefit teachers who as wish to adopt and adapt EjsS material on ComPADRE for their own teaching and more advance teachers to teach physics using computer-based modeling. During the workshop we will discuss the general pedagogical and technical issues in the design of interactive computer-based tutorials as well as how the NRF2011-EDU001-EL001 customized models has been adapted to our Singapore schools context (Models and complete with worksheets http://weelookang.blogspot.sg/2013/10/6th-ipsg-level-physics.html). All workshop materials will be made available through the Open Source Physics Collection on the ComPADRE National Science Digital Library http://www.compadre.org/OSP/.

2) Activities

This 3.5 day workshop and consultations aims to provide a hands-on bootstrapping experience to the ComPADRE Open Source Physics (OSP) project and the Easy Java/JavaScript Simulations (EjsS) modelling and authoring tool. This 3.5-day workshop combines morning expositions and practical sessions where participants will work in teams/individually on computers provided by the organizers followed by afternoon one-on-one consultations with some references to NRF2011-EDU001-EL001 customized models and worksheets with the workshop leaders. Participants will study and explore, step by step, important computational and pedagogical examples, such as the gravitational N-body and the simple harmonic oscillator models, to learn how they have been implemented in EjsS, and then modify these examples to add new capabilities.
 
On Day 2 PM, CPDD Director, Deputy Director and Officers had a rich up close discussions on topics on the Student Leaning Space (Blended-Face to Face&Online Learning, Massive Online Open courses, Open educational Resources)  for Physics resource development, curation etc. 

3) Impact

As of 04 Dec 2014, out of 20 participants, there are 8+2=10 creator/users of models, 7 customisers and 1 starting a NIE-MOE grant and 2 yet to confirm their models. 

This outstanding achievement is possible largely due to 

  1. skillful and inspiring teaching and facilitation by the consultants (see Facebook post by Leong Tze Kwang thanking them) 
  2. the high levels of motivation of the participants to create models that can be readily used in their own area of work. 
  3. the excellence service from the local organizers loo kang, sze yee and tat leong.

Prof Wolfgang and Paco didn't just teach us how to make amazing JavaScript applet but also inspire us to become better teachers. Thanks Lookang for organizing the workshop. I finally get down to work. Will start making more JavaScript applet. — with Lye Sze Yee,Thomas Yeu, Dave Lommen, Ezzy Chan, Loo Kang Lawrence Wee, Francisco Esquembre, Andy Luo Kangshun and Ng Boon Leong.

4) Follow-Up/Learning

We have achieved the aim to provide a hands-on bootstrapping experience for 20 participants (14 teachers, 5 HQ officers and 1 NIE researcher) to the ComPADRE Open Source Physics (OSP) project and the Easy Java/JavaScript Simulations (EjsS) modelling and authoring tool. 

The benefits to teachers include 10 creating new models, 7 adopt and adapt EjsS material on ComPADRE for their own teaching and more advance teachers to teach physics using computer-based modeling. 

Total funding cost is around S\) 15,000 from NRF, managed by NIE and MOE, for both professor’s 4 full days of workshop, consultation, public lectures at NIE5-LT12 and close up discussions with DCPD, DD Sc and their team of CRDO officers. The professional development for teachers/ HQ officers is high in terms of the artifacts of learning and networking with international world-best researchers. DCPD and DD Sc also glean insights to the student learning space creation and population of resources from day 2 PM rich discussions.

  • What is the main goal of the Open Source Physics (OSP) project and how does it relate to the Easy Java/JavaScript Simulations (EjsS) tool?
  • The Open Source Physics (OSP) project aims to create a large, freely accessible library of physics simulations, complete with source code and educational materials, under a Creative Commons open-source model. EjsS is a code generation tool that utilizes the OSP code library to help users create interactive simulations. EjsS provides a user interface, allowing users to draw 2D and 3D objects, implement numerical solutions for ordinary differential equations, and display data using tables and graphs, effectively making complex physics simulations more accessible to educators and learners. It focuses on modeling rather than the intricacies of programming.
  • What is Easy Java/JavaScript Simulations (EjsS), and how can it benefit educators and students?
  • EjsS is a free, open-source authoring tool designed to make it easier to create dynamic simulations using Java and JavaScript. It minimizes the programming effort needed to develop interactive simulations, allowing educators and learners to focus on modeling physics phenomena. EjsS is suitable for educators to create engaging teaching materials, researchers to prototype applications, and authors to create and share Java/JavaScript-based curricular resources. It simplifies the implementation of computational modeling in education.
  • What were the key activities and objectives of the 2014 workshop led by Professors Christian and Esquembre in Singapore?
  • The 2014 workshop, held in Singapore, aimed to provide a hands-on introduction to the OSP project and the EjsS tool. Participants, primarily physics educators, attended morning sessions to explore existing simulations, learn the fundamentals of EjsS, and understand how to modify them for their educational contexts. The afternoon sessions were dedicated to consultations, where participants could discuss their specific curriculum design challenges and learn how to integrate OSP and EjsS into their teaching. Participants were encouraged to create their own models. Additionally, there was a public lecture and discussions with Singapore Ministry of Education personnel.
  • What specific topics were covered during the workshop sessions?
  • The workshop sessions progressively covered a range of topics. Beginner sessions introduced the OSP-EjsS-ComPADRE platform, basic EjsS workspace, and the Tracker video analysis tool. Intermediate sessions focused on creating models using EjsS, including variables, functions, ODE (Ordinary Differential Equations) editors, and how to bind model variables to view elements. Advanced sessions delved deeper into complex models, including arrays, N-dimensional ODEs, and external libraries. Expert sessions covered curriculum development, simulation distribution, and creating digital libraries using EjsS.
  • How does the workshop incorporate hands-on learning and collaboration among the participants?
  • The workshop design emphasizes hands-on learning and collaboration. Participants worked both individually and in teams on computers provided by the organizers. They explored pre-existing simulation models, then modified them, adding their own features. The workshop offered a combination of morning expositions, practical application sessions, and afternoon one-on-one consultations with the professors, ensuring that participants could both learn and get tailored support.
  • What are some of the example models and pedagogical examples that participants explored during the workshop?
  • Participants worked with various models including the gravitational N-body model, the simple harmonic oscillator, and free fall with collision detection, among many others. These examples were used to show how to implement physical systems in EjsS. They also explored Tracker, a video analysis tool, to analyze real-world motion and to teach physics concepts. These provided opportunities for participants to both understand the physics and the underlying code required to build them. Additionally they examined how these were customized for the Singaporean context.
  • What is ComPADRE, and how does it relate to the OSP project and the workshop?
