History of GeoGebra

2002 - 2012

Visualizing

GeoGebra = Geometry + Algebra

students can “see” abstract mathematical concepts

GeoGebra 4: Dragon Flies & Math

Algebra Window

Geometry & Graphics Window

Connecting the Dots

students can connect different areas of mathematics

Experimenting

learning becomes discovery

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

A special kind of institute network

Core Aims of IGI

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.

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

120 Current GeoGebra Institutes in 80 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
• 107 Institutes (75 Countries)
• GG in textbooks in 40 Countries
• 43 Developers
• 200 Translators
• 35.000 Online Learning Objects

• Individual Workshops
• GeoGebra Conferences
