Extension:GeoGebra

The GeoGebra extension allows to use GeoGebra applets on a page.

GeoGebra applets use Java technology to combine an interactive geometry environment with the ability to directly enter equations and coordinates making it very useful in math education and math explorations.

The latest versions of GeoGebra provide applets using HTML5/JavaScript/CSS instead of Java. These applets can be used on moblie devices like Android tablets and iPads, even on a few smartphones (depending on CPU speed).

GeoGebra applets and worksheets are shared at: www.geogebratube.org (community)

Usage
You can export a GeoGebra file to a wiki very comfortably (since GeoGebra 3.2.33.0).

Use the export function of GeoGebra:

Choose File - Export - Dynamic Worksheet as Webpage... Then go to "Advanced" and choose "Clipboard:MediaWiki" (bottom right).

See the tutorial at wiki.geogebra.org: GeoGebra with MediaWiki

Paste the clipoard to your wiki in edit mode. Done! This will create a tag like this:

Upload of ggb files to the wiki is obsolete and not longer supported!

You can also pass GeoGebra applet parameters. See Parameters

Example:

Installation
If you are using an older version (<= 1.16.x) of MediaWiki, you will have to use an older version of this extension. Version 2.7i can be found at an older version of this page

Status changed back from stable to beta
''' Wiki admins: Please install and test latest version 3.0d-web. '''

Version 2.7 was tested with with many wikis, without critical errors. Status of Version 2.7i was changed from beta to stable at 2011-03-05.

Version 3.0d-web is not yet installed at other wikis. Carefully I changed status back to beta at 2012-08-09.

Incompatibility with MediaWiki 1.19 fixed
Zbynek Konecny from the GeoGebra team told me that this line did not work after updating to MediaWiki 1.19:
 * $ggbFile =  Image::newFromName($ggbBinary);

Fixed with version 2.8a. Tested at wiki.mathebuch-online.de

Version 3.0d-web was tested at geogebratest.grossmann.info
