What is GeoGebra?
GeoGebra = Geometry + Algebra
Geometry & Graphics Window
Free Software > Cost-Free
Free software is a matter of liberty, not price.

To understand the concept, you should think
of
free
as in
free speech
, not as in free beer.

GeoGebra Institute
2007 - 2012
Core Aims of IGI
Teacher training and support
Offer workshops & support
Material and software development
Share free materials
Research
Encourage and coordinate collaborative research
(Outreach)
Enable disadvantaged communities
140 GeoGebra Institutes at universities in 80 countries
http://www.geogebra.org/community
Difficulties of serving large communities
GIs can reach mostly local teachers/communities

Members work in different institutions

Large geographical areas to cover

If many people involved that results too large staff

Maintain independence of work
Towards a GeoGebra Institute network
Rather than country-wide institutes, GI network serves better a country’s needs

Establishing local institutes, but encourage a coordinating committee (locally decided)

Individual application followed by a network application
Institute network case: Spain
Planned Institute Centres
Linz, Austria – Software development

Budapest, Hungary – Community support

Cambridge, UK – STEM and Research

Possible other centres
GeoGebra Events
http://www.geogebra.org/events
Individual Workshops
GeoGebra Conferences
IGI
Plans
Community and project support
Assist the community with
Events
Research training
GeoGebra materials
Activities

Distribute responsibilities (Committees)
Research
Coordination
Support

Partner school network
Involve more teachers in the community

Schools experimenting with the use of GeoGebra

Encourage collaboration among schools and teachers

Be able to offer more support

Sponsors can donate to schools
If you want to go fast,
go alone.

If you want to go far,
go together.

What about ... ?
Coming up...
GeoGebra 5.0 Beta
3D graphics
Python scripting
Theorem Proving
STEM: Kinect, wii, Raspberry Pi, etc.
GeoGebra works in Chrome (without Java)
Available on Chrome Web Store
Supported by Google
We hope to soon start work on adding:

2nd Graphics View
Spreadsheet View
CAS View
3D View
What is working:

All commands, including the new ones from GeoGebra 4.2
Algebra View
Toolbar
Input Bar
Style Bar

Bonus features that the Java version doesn’t have:

Save and share your .ggb files to Google Drive
Edit -> Insert Image from -> Webcam
Equation editing in the Algebra View
Google
ChromeApp
Try it!

Crowdfunding
via Kickstarter
Dynamic mathematics meets touchscreen.
GeoGebra Tablet App
The Nordic GeoGebra Network is a collaboration between teachers, teacher educators and researchers in mathematics education with the aim of sharing materials and exchanging experiences concerning the use of ICT in the teaching of mathematics with emphasis on the GeoGebra software.
A special kind of institute network
