Open Source Physics modelling tool allows teachers to create simple mathematical computational model (simulation), exportable into an android APK. This 4 day workshop will support teachers to

Create a brand new simple computational model using Open Source Physics toolkit
Export existing model with supporting text into android APK file for deployment.
Reflecting/presenting teacher performance task sharing
Basic how to and explore the Easy Java/JavaScript Simulations (EjsS) modelling and authoring tool.
Create brand new simple mathematical and physics computational model
remix existing models in the digital libraries, especially the Singapore Library.
create or remix one model based from an existing example in the library
export 1 to 2 existing model with supporting text into android APK file for deployment.
Content:Introduction to the workshop
Exploration of the OSP-EJS-ComPADRE Platform
Exploration of EjsS
Independent work and consultations on curriculum design
Creating simple models with EJS
Creating models with EJS part 2
Remixing one model
Exporting as android APK
Reflecting/presenting teacher performance task sharing
This 4 days workshop support teachers to use Open Source Physics modeling tool to create own or customise from the Digital Library other's HTML5 simulation to bring physics concepts into the classroom.
Equipped with a personal laptop and using software like Android Studio and Ionic Framework, it is possible to export this simulation as an Android App for learning anytime, anywhere.
Motivated and ICT savvy participants will be more likely to benefit from this workshop series, to bootstrap their journey to create learning environment using simulations on student's mobile devices, bringing forward S’pore’s education system.

Creating Creating ICT Learning Experiences for Kinematics-Dynamics-Energy (Part 4)

Dear workshop participants,

Thank you for signing up for the 4th and final workshop, this time focusing on sharing by teachers.

Goal: Share any effective ICT lesson preferably, that you want more people to know about. for example, using Tracker, Easy JavaScript Simulations or PheT, Energy2D etc.

This is your opportunity to share you joy of learning.

Title: Creating Creating ICT Learning Experiences for Kinematics-Dynamics-Energy (Part 4)
Date: 18 April ( upcoming for synthesis and network learning)
Time: 1430 - 1730 hours
Venue: eduLab@AST (Block J Level 4) 2, Malan Road, Singapore 109433, Academy of Singapore Teachers, Tel: 6664 1450 (Walk towards the canteen and climb the stairs up to highest floor following the green signages)

Getting there: Please click for details to AST.

Parking: MOE staff are permitted to park their vehicles within AST.

Refreshments: A short tea break at 2:30pm with some light snacks will be provided.

Collision Carts Simulator for Android and iOS

Just refined the Collision Carts Simulator for Android and iOS

How to fix iOS comboBox problem using EJSS-ionic templates

In my research, iOS has been harder to make App for, compare to Android.

A combobox problem has now a solution thanks to Professor Felix, creator of JavaScript favor of Easy Java/Javascript Simulation tool.

Before generating your ios app, it is needed to do the following step:

- edit www/js/app.js

- search ".run(function($ionicPlatform) "

- change
cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true); to cordova.plugins.Keyboard.hideKeyboardAccessoryBar(false);

How to Update Ionic to 2.2.2 using command line

This are some of the things issues i encountered while updating to Ionic 2.2.2 because the command ionic does not work.

  1. ionic does not work. Cannot find module 'internal/fs' (CLI v2.0.0) Your system information: Cordova CLI: 6.4.0 Ionic CLI Version: 2.0.0 Ionic App Lib Version: 2.0.0 ios-deploy version: Not installed ios-sim version: Not installed OS: Mac OS X El Capitan Node Version: v7.8.0 Xcode version: Xcode 8.2.1 Build version 8C1002
  2. so type in the command line, the new ionic is being installed 
    • sudo npm install -g ionic
  3. by now, ionic should work fine 
  4. the ionic 2.2.2 recommends installing 2 new stuff 
  5. type in to install 
    • sudo npm install -g ios-sim
  6. type in to install 
    • sudo npm -g install ios-deploy --unsafe-perm=true
  7. type in ionic info shows
    1. ionic info
  8. Enjoy! ** BUILD SUCCEEDED **
