The GeoGebra Mediawiki Extension
Introduction
- Rudolf Großmann, Stein (at Nuremberg), Germany
- Teacher (Mathematics, Physics) at Gymnasium Stein
- Maintainer of GeoGebra Mediawiki Extension and Formelapplet Mediawiki Extension
- Creator of FormelApplet
How to import a GeoGebra applet into a wiki
- Help page: Embed a GeoGebra Applet into this Wiki
- Learning by
doingwatching a demonstration. ;-)- Example: Integral Command
- Help appreciated for i18n of Help page. Done for en, pt, es, fr.
Which wikis use the GeoGebra Mediawiki Extension?
- List of installations: http://www.mediawiki.org/wiki/Extension:GeoGebra/Examples
- ZUM Wiki (in German)
- ZUM means Zentrale für Unterrichtsmedien (Center for Educational Media)
- I was invited to the ZUM-Wiki-Seminar 2011
- There is a project "Creating Online Exercises for Math, Physics and Chemistry" at ZUM:
See e.g. Mathe Klasse 10
- GeoGebra Wiki - of course!
How to install the GeoGebra Mediawiki Extension at your wiki
- Wikipedia uses MediaWiki software. MediaWiki software is Open Source. Extensions are written in PHP.
- The version page of the wiki shows a list of all installed extensions, with links to the documentation: Special:Version
- Here is the direct link to the documentation of the MediaWiki Extension: www.mediawiki.org/wiki/Extension:GeoGebra
- You need admin rights for the wiki (FTP access to the PHP scripts of the MediaWiki software).
- Wikis not using MediaWiki software will not be able to use the extensions of www.mediawiki.org.
Why not at at Wikipedia?
- For security reasons Java applets are generally not allowed at WikiPedia.
- The MediaWiki Extension doesn't allow to use an arbitrary Java applet. It allows only GeoGebra applets.
- Malicious code could only be injected into Wikipedia, if the GeoGebra code would be malicious.
- If the guys at Wikipedia trust in the GeoGebra makers, there is no security problem!
- Who should try to convince the Wikipedia admins?
Difficulties
- The Same origin policy does not allow Java to load a GeoGebra file (*.ggb) and the GeoGebra applet (geogebra.jar) from different servers.
- There are some strategies to deal with these restrictions:
- Use of digitally signed GeoGebra applets.
- Storing the GeoGebra jar files in a subdirectory of MediaWiki and using parameter useLocalJar='true'.
- Using an applet parameter instead of a ggb file:
Short history
- May 2008: Installing my own wiki at http://wiki.mathebuch-online.de for experiments with MediaWiki extensions.
- June 2008: GeoGebra MediaWiki Extension published (Version 1.0k).
- June 2008: FormelApplet MediaWiki Extension published.
- June 2009: Introduction of parameter useLocalJar=true (Version 2.0p).
- Sept. 2009: Status of Version 2.0p changed from beta to stable.
- Dec. 2009: New parameter ggbBase64 replaces filename (Version 2.6m).
- Oct. 2010: Workaround for "Chrome error" (Version 2.7f).
- March 2011: Status of Version 2.7g changed from beta to stable.
Future
- GeoGebraMobile MediaWiki Extension http://wiki.formelapplet.de/wiki/GeoGebraMobile
- Feb. 2011: Page Extension:GeoGebraMobile created, but extension not published yet.
- GeoGebra will replace GeoGebraUploader. What about GeoGebraWiki?
