You know yourself how good GeoGebra is, and so do the millions of users. But we are trying to go further. We wish to collect hard evidence on the impact of GeoGebra.

This may come from activities you have undertaken or that you know of, for example:

• Best practice examples: lesson plans and evaluation
• User quotes
• Controlled studies
• Statistical evidence
• Academic/journal or conference articles

In return for sharing with us, we will feature your work in GeoGebra blog posts, in a PREZI presentation GeoGebra STEM – Impact and Evidence, a joint academic presentation…and last but not least the US Mid-West GeoGebra journal.

To get the ball rolling, based on a quick Google search, we have already found evidence which you can see on:

But this is just a start – we want to collect better and better evidence showing the impact of GeoGebra! Please send your information – lesson plans/research articles/studies/links etc to this e-mail address, with the subject line: EVIDENCE: institutes@GeoGebra.org

Their reports found evidence for the ease of GeoGebra per se, and also the immense impact of GeoGebra as a global community learning tool. In their own words:

I could easily use the basic functions without any tutorials. I found some useful videos and tutorials in the GeoGebra forums and on YouTube. This video, helped me to understand the basics of animating in GeoGebra:

I used this forum topic http://www.geogebra.org/forum/viewtopic.php?f=2&t=17468 to learn how to create moving squares. It seems to me that the GeoGebra community is very active. There was a forum topic or video for everything I searched for. It took very little time to find answers to my questions. I think I learned a lot about how real work is done at a company. We had Skype conferences and real life meetings.

The internet was also tremendous help for me. GeoGebra.org has its own video tube, own forum where you can share opinions, ask questions, suggest solutions etc. This creates a whole GeoGebra community which i believe is a key essential for this software. We held skype conferences regularly to keep each other updated, we have a Facebook group which made communication and organization much easier. We also have a headquarter at Milestone where at the beginning many presentations took place to introduce GeoGebra and GeoGebraSTEM.

This physical and virtual mix has proven very powerful. The Geogebra STEM examples from around the world and framework can be seen in: GeoGebra STEM: http://prezi.com/92z8atpqk1gr/geogebra-stem/

The work of Tran and Bence evidencing the impact of the GeoGebra tool and community can be seen towards the end of:The Impact of Geogebra – Evidence: http://prezi.com/bsi-qdd6jr6r/the-impact-of-geogebra-evidence

We are now issuing a call for new GeoGebra Interns and also Mentors from all over the world! The project will be again based in the Budapest Milestone office, but now open to the 149 (and counting) Geogebra Institutes around the world!

The challenge, focussing on GeoGebra STEM and the community, will be announced and launched June 15th.  It could be a summer project or longer. Deadline for completion will be October 15th.

To register your interest, please contact Julia Vida before the 15th June at institutes@geogebra.org
