Join us at our GeoGebra Global Gathering (G3, 2015) July 15 – 17 in Linz in Austria and register now!

Because there is only a limited number of participants we can host, we highly recommend to register for our gathering as soon as possible to make sure you can join us this July. Please find more information about all the practicalities in our G3 2015 GeoGebraBook.

We are looking forward to seeing you this summer in Linz!
Markus and the GeoGebra Team

• a brand-new user interface that works great both with Touch and Mouse, so you can use it on laptops, desktops and tablets
• all the great features you know from our desktop app: Graphics, Algebra, Spreadsheet, CAS and 3D
• direct saving/loading your files to GeoGebraTube using your GeoGebra, Google, Facebook, Twitter or Microsoft account, so you can access your work on all devices everyhwere

Now, we are ready to show the first beta version of our new GeoGebra Chrome App with 3D View.

Of course we’re still developing the Java desktop version alongside and GeoGebraTube will support displaying 3D files using WebGL / HTML5 as well. Our 3D applets already work on devices with Android 4.4 (and Android 4.3 devices supporting WebGL), for example, Nexus 7 Phones and Nexus 10 Tablets. If you have an iPad you will have to wait for iOS 8 to be released later this year to use our 3D applets on GeoGebraTube.

Over 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:

• Pythagoras: http://tube.geogebra.org/student/m125392
• Patterns of a Cube: http://tube.geogebra.org/student/m115740
• Sine Function: http://tube.geogebra.org/student/m124879
• Lower and Upper Sum: http://tube.geogebra.org/student/m10637

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

Mike & the GeoGebra Developer Team

• More powerful and faster CAS View
• Sign-in to GeoGebraTube to search / share materials
• Object Properties and Graphics View 2 now also available in our Web Application
• GeoGebraTube now supports Private & Shared materials as well as Public as well as HTML5 applets with multiple views
• New language: Latvian
• Please find all details in our GeoGebra 4.4 Release Notes

As well as being much faster, the new CAS View can tackle harder problems than before and solve coordinate geometry problems exactly:

Have fun playing and thanks for your feedback in advance!

Mike, Markus, and the GeoGebra Dev Team

• New tools: area, length, slope, circle with point and radius, angle with given size, segment with given length
• Increased font size, bigger sliders
• Support for right-to-left languages
• Decreased app size
• Bugfixes related to opening files with images
• Windows: faster app start time
• Android, iPad: opening/saving files from/to external apps

• 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.

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.

Key features include:

• Integrated GeoGebraTube Search
• Worksheet View for presenting materials
• Graphics and Algebra View
• Touch-optimized Toolbar and Stylebar
• Powerful Input Bar
• Fully compatible to desktop version

Of course, this is only the start to a great new chapter for GeoGebra, and we have lots of plans on how to continuously improve and extend our apps. As always, please let us know your feedback and ideas in our user forum and continue to build the world’s best math tool together.

Thank you,
Markus and the GeoGebra Team
