EJS and comPADRE

Have you developed a great EJS simulation that works well in your class?

Why not share it with other physics teachers by adding it to the comPADRE OSP collection of EJS simulations?

EJS is part of the Open Source Physics (OSP) Collection hosted by the comPADRE Digital Library, a network of educational resource collections supporting teachers and students in Physics and Astronomy. As a comPADRE user you may explore collections designed to meet your specific needs and help build the network by adding resources, commenting on resources, and starting or joining discussions. You must register (registration is free) and login with a ComPADRE account to be able to upload files.

Click here to see a list of current EJS resources on comPADRE. Note that most of these are EJS simulations contributed by teachers like you! If you've developed an EJS simulation that you have successfully classroom tested, then please consider sharing it with the comPADRE community. Note: with rare exceptions, your zipped EJS model (program and data altogether) should not exceed 10MB.

Here's how to add your own EJS simulation to comPADRE:

1. Prepare your supporting documents (instructions, report forms, etc).
   • Convert all documents to PDF or XHTML.
   • PDF documents will always be displayed in a separate PDF viewer.
   • XHTML documents may be displayed in a web browser or in EJS itself. To display in EJS, add them to your Description pages.
2. Export your simulation as a JAR file. Keep instructor materials, if any, separate.
   • Open your simulation source file with EjsS.
   • It is a good idea that you fill in the Metadata section of the Simulation information dialog (left-top icon in EjsS).
   • Left-click the Package icon (or right-click this icon and select "Package this simulation only").
3. Optionally, export your simulation sources as a ZIP file, for sharing them, too.
   • Open your simulation source file with EjsS.
   • Right-click the Package icon and select "ZIP the simulation source files").
4. Log into comPADRE (registration is free) and open the Suggest a Resource page. Unless you have instructor materials or other ancillary resources, simply enter the information in the Quick Suggestion tab, attach your exported JAR file, and click the Make Suggestion button. That's it! The OSP Collection editor will review your submission and, if accepted, create the full record for the experiment.
5. If you wish to include additional resources along with your JAR file, such as the ZIP file with the simulation source code, use the Full Suggestion Wizard tab on the Suggest a Resource page.
