4.0 the current stable version

4.2 including CAS

(Planned release in September 2012)

4.2 beta - CAS

Python window

5.0 beta - 3D

Automatic Theorem Proving

GeoGebraWeb

Kinect, wii, Raspberry Pi, etc.

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

We hope to soon start work on adding:

  • 2nd Graphics View
  • Spreadsheet View
  • CAS View
  • 3D View

Open Source > Free

Experimenting

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.

(Free Software Foundation)

learning becomes discovery

If you want to go fast,

go alone.

If you want to go far,

go together.

Core Aims of IGI

Towards a GeoGebra Institute network

  • Teacher training and support
  • Offer workshops & support
  • Material and software development
  • Share free materials
  • Research
  • Encourage and coordinate collaborative research
  • (Outreach)
  • Enable disadvantaged communities
  • 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

World Wide User Community

Difficulties of serving large communities

Planned Institute Centres

100 Current GeoGebra Institutes in 70 countries.

More coming soon …

  • 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
  • Linz, Austria – Software development

  • Budapest, Hungary – Community support

  • Cambridge, UK – STEM and Research

  • Possible other centres

http://www.geogebra.org/community

  • 900,000 unique visitors/month
  • 400,000 downloads /month
  • 6.2 million downloads in 2011
  • On 5.5 million classroom laptops

GeoGebra Events

  • 62 Languages
  • 190 Countries
  • 100 Institutes (70 Countries)
  • GG in textbooks in 30 Countries
  • 43 Developers
  • 200 Translators
  • 35.000 Online Learning Objects
  • Individual Workshops
  • GeoGebra Conferences (1 in 2009; 12 in 2010; 25 in 2011)
  • 40-50 expected in 2012
