If you’ve read my posts, you know I’m a bit obsessed about using Geogebra. Whether you look at how it has changed the structure of my class, how I help students get feedback as they learn, or as one of the tools I use to figure out things that interest me, there are plenty of ways it has had an impact on my teaching and learning.
First, the basics.
The current version is Geogebra 4.2. This new version has some nice new features, including a computer algebra system. You can either download the Webstart version, or download an offline version that will install on your computer when you are offline.
There is also a beta version of Geogebra 5, which adds many additional features, but one of note is the ability to graph in 3D. Try the Webstart version here.
What can it do?
The best way to find out is to play with it yourself. If you are like most people, you can do this for a short while, but eventually you get an itch to see what it can really do. Here are some options:
- GeogebraTube – a searchable and interactive database of what people have put together using the software. My humble corner of this universe, containing some of my creations can be found here.
- Here is my repository of many of my own sketches.
How can I get help using it?
Great question! There are many options.
- The manual for using Geogebra is this wiki at the Geogebra website. You can go here and find tutorials, information on features of the program, and find out about upcoming events. You can also go to…
- …the community forum. There are people from all over the world browsing the forum with questions like yours, and really excellent answers. Since it truly is a world wide knowledge base, if you post a question at 3 AM in your time zone, someone is reading your post while drinking their morning coffee. Response is fairly quick!
- Search Twitter for the hashtag #geogebra, and you’ll find lots of people talking about their work with it.
I’ve also made a number of blog posts about my use of Geogebra in the classroom. Click here to see them in one place.
Please contact me for more information on how you can use Geogebra in your classroom. I have lots of ideas, successes (and failures) that I would love to share with you.
