CC contributions: Videos and Interactive Java Applets

SG-adopter and educator, Loo Kang (, shares the following resources under CC licenses:

He also added that the CC-licensed Java Applets he made “are the real gems”. The Applets can be found on the NTNU virtual lab forum:

Loo Kang suggests that those interested in using the Java Applets can read his blog to get a sense of what/ how the Java Applets can help people learn physics.

From what I found out, an applet is:

“a program written in the Java programming language that can be included in an HTML page, much in the same way an image is included in a page. When you use a Java technology-enabled browser to view a page that contains an applet, the applet’s code is transferred to your system and executed by the browser’s Java Virtual Machine (JVM).” ~ Source:

I emailed Loo Kang for more info on how one can use the Java Applets, and he explains:

  1. To download the applet and it source codes, register at
  2. Using this link as an example (, download the working applet from Download EJS jar file (913.8kB).
  3. Double click the downloaded file to run it.
  4. The license is auto generated by the Taiwanese Professor, Fu-Kwun Hwang, under a Creative Commons Attribution 2.5 Taiwan License. But those I make with his help and others in the educator professional learning community, I license under a Creative Commons Attribution 3.0 Singapore License.
  5. Developers/educators can download the source codes from Download EJS XML source and remix the applet (use Ejs tool – to suit their own classroom needs, under the Creative Commons Attribution 3.0 Singapore License.
  6. The embedding codes can be copied too but that isn’t the strategic intent of sharing the source codes. The whole idea is to empower educators to make changes themselves, learn and improve the java applets (interactive learning environments etc.).

Thanks for sharing, Loo Kang.

  1. yes!
    open source has indeed open doors to learning, now you can learn physics by examining and remixing the codes in easy java simulation projects.
