Faster, Smaller GeoGebra Applets

We were very pleased with how the switch to HTML5 on GeoGebraTube went at the end of last year, and with how the community responded by helping each other to sort out the minor changes from our Java to HTML5 applets, eg changes needed to LaTeX. But as you know, we’re always working to make GeoGebra better, faster & more fun each year and we’ve never sat back and thought “it’s finished”.

GeoGebra Applet on PhoneOver the last year we’ve been working on a top-secret project to improve GeoGebraTube which is now ready for its first public showing. At the moment a typical HTML5 applet downloads over 3MB when it’s first run and starts up in about 3s (on a fast computer). With our new “GeoGebra Applet Compiler” technology, the same applet downloads only about 0.4MB and starts up in 0.8s on the same machine. In addition our compiled applets run much more smoothly even on slower devices and support retina resolutions on iPhone 4, 5, iPad 3, 4, Nexus 7, Nexus 10 etc.

Try some example applets using our new GeoGebra Applet Compiler:

There are a few limitations about what will work with the new applet compiler (we’ll release details later) and it will only work inside GeoGebraTube, so we will still continue to improve and support our other versions of GeoGebra as well, of course. Our goal is to make these new faster and smaller GeoGebra applets the default for most materials on GeoGebraTube automatically in the background without you having to do anything. We will keep you posted ;-)

GeoGebra 4.4 and HTML5 applets coming 1st December

We have some exciting announcements for you:

  • GeoGebra 4.4 will be released on 1st December 2013. The main change is that the CAS View is much better & faster. You can already try our Release Candidate.

  • On 1st of December, we will also switch GeoGebraTube to “HTML5 preferred”. This means that we will display materials using our HTML5 applets by default where possible, and deliver Java applets only for older browsers (like Internet Explorer 8). There are a few advanced things that are not fully supported in our HTML5 applets yet (e.g. some LaTeX commands), so please check your GeoGebraTube worksheets by clicking on “View as HTML5 Applet”. If you need help updating your worksheets, please ask in the forum.
    We have also added an option in GeoGebraTube to set the preferred applet type, so you can e.g. force an applet to still be shown in Java (Edit Material -> Advanced Settings -> Preferred Applet Type -> Default/HTML5/Java), however the future is definitely HTML5 ;-)

  • If you are hosting GeoGebra applets on your own website, please see this important announcement to make sure these applets will continue to work well in the future also.

GeoGebra, the Wikispaces Way

GeoGebra and our friends at Wikispaces got together to make using GeoGebra in your Wikispaces classroom fun and easy with our new GeoGebra widget!

Why do we like Wikispaces so much? Well, its probably because they are a lot like GeoGebra and our community! Wikispaces is one of those amazing free resources that actually makes teaching and learning easier, interactive, and social. Hmmm, sound familiar?

Not only is Wikispaces probably the best wiki tool available to teachers and students everywhere, it has also inspired a generation of collaborative learners, with as many as 35 million visitors to Wikispaces every month. That’s what we call a critical mass of learning power!  Now… mix in a little GeoGebra and what have you got?…dynamic STEM teaching and learning wiki pages everywhere!

Want to read more? Check out what they are saying about GeoGebra on the Wikispaces blog. It’s not only pretty flattering about our community, but also tells you how to get started using the GeoGebra widget on a Wikispaces Classroom page of your own.

North American GeoGebra Conference 2013

On August 3 and 4, over 350 mathematics educators, teacher educators, mathematicians, and students converged on Miami University in Oxford, Ohio, USA for the 4th Annual North American GeoGebra Conference.  This is the third year in a row the GeoGebra Institute of Ohio has hosted a free summer conference (Midwest Regional GeoGebra Conference), and the first year for hosting the North American Conference.

NA Conference 2013  NA Conference 2013 session

Attendees came from across North America and as far away as New Zealand. The conference featured over 50 content-based sessions. In addition to the content sessions, participants who were interested in learning how to use GeoGebra could have attended a 2-day “Newbie” workshop. Participants could also have attended a day-long strand on Digital Ethics, featuring sessions on privacy rights, ethics of digital games, and other digital issues.

The conference was opened by Keynote speaker John Golden from Grand Valley State University. Slides from John’s presentation – Teaching for Creativity – can be downloaded at http://bit.ly/goldenggb13. You can follow John on Twitter @mathhombre.

In addition to the host GeoGebra Institute of Ohio, four other North American Institutes were represented at the conference:

  • GeoGebra Institute of Maine (James Quinlan)
  • GeoGebra Institute of Minnesota (Dave Pugh)
  • GeoGebra Institute of Central Florida (Janet Andreasen, Erhan Selcuk Haciomeroglu, and Maria Capursi)
  • GeoGebra Institute of South Florida (Ed Knote)
  • GeoGebra Institute of Canada (Geoff Roulet and Jill Lazarus)

Rubik’s Cube World Champion powered by GeoGebra

Marcell Endrey is a computer science student from Hungary with an interesting hobby: solving the Rubik’s Cube. Just solving it soon became boring for him, so he started doing it blindfolded! Today, Marcell is the world’s fastest blindfolded speedcuber and currently holds several world records including solving the 4×4 and the 5×5 cube. His current best time on the 3×3 cube blindfolded is 26.13, you can watch him solving 3×3 cube in 26.36 seconds.

Thanks to support from GeoGebra, Marcell was able to travel to the USA last week and attend the Rubik’s Cube World Championship 2013 in Las Vegas, see the following video: Marcell at Rubik’s Cube World Championship 2013

Marcell was very successful and is now world champion for blindfolded 3×3, 4×4, 5×5 and multi 3×3 cube solving. We are happy that GeoGebra made it possible for him to participate and live his passion for math and science. Congratulations, Marcell!

Do you want to meet Marcell in person? You will get a chance at the GeoGebra conference in Budapest in January 2014.
