http://www.geogebra.org Community & Current Projects History Development Online Community Get involved! 2002 - 2012 History of GeoGebra GeoGebra = Geometry + Algebra Geometry & Graphics Window Algebra 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
Encourage and coordinate collaborative research
Enable disadvantaged communities 120 Current GeoGebra Institutes in 80 countries
More coming soon … 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
Research training
GeoGebra materials

Distribute responsibilities (Committees)
… 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. Warren Buffett GeoGebraTube One Laptop per Child Project Argentina 3million netbooks Education for the 21st Century Collaborative Experimental Accessible High School in Zambia Google Drive integration Real time collaboration in the classroom online Students Teachers Geogebra "Teachers"

Community http://twitter.com/geogebra http://blog.geogebra.org Development team http://geogebra.org/team http://dev.geogebra.org Not enough... Still lots of devices without GeoGebra... Coming up... GeoGebra 5.0 Beta
3D graphics
Python window
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
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! http://blog.geogebra.org/2012/06/geogebra-chrome-app-released/ http://web.geogebra.org 4.0 Current Stable version
4.2 Release Candidate public! Get involved in development! Real 3D online repository for .ggb files

via Kickstarter Dynamic mathematics meets touchscreen. GeoGebra Apps for Tablets TOP SECRET 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 http://blog.geogebra.org/2012/11/4-2-release-candidate/ http://www.geogebratube.org/student/m20511
