What is GeoGebra?
GeoGebra ...
- is an interactive geometry and algebra application;
- is an authoring tool one can use to create interactive learning materials;
- is open source software written in Java and thus available on multiple platforms;
- has won at least 13 educational technology awards since 2002; and
- has an established and growing community of users and developers around the world.

Some GeoGebra Examples

Modes of use of GeoGebra - I
- A tool for creating applets
- Easy to produce easy to use applets
- Fairly "light"
- Broad feature set
- Applets can be made robust for student use
- A tool for classroom demonstrations

Modes of use of GeoGebra - II
- A tool that students use to create demonstrations
- Useful for discovery-based learning
- Requires students to learn some syntax
- Useful for quickly creating a graph or image for inclusion in a document (can export graphics view or any part of it as an image file)

Getting Started

GeoGebraWeb - I
- GeoGebraWeb (previously known as GeoGebraMobile) is the name of the project that brings GeoGebra to platforms that do not run Java (for example, tablet devices and smart phones), via export to HTML5
- Export to HTML5 available in GeoGebra 4 (and later)
- Currently under development (alpha), but some GeoGebra applets run well already
- Currently only the Graphics view appears in GeoGebraWeb
- Sample applet: Angle bisectors activity

GeoGebraWeb - II
- Applets tend to load slowly
- Links for more information:
- Applets on GeoGebraTube automatically load the HTML5 version on non-Java platforms
