Getting the word out on GeoGebra

Maria Droujkova has done some great work putting together some Elluminate sessions on Math 2.0... and she has more to come. On Saturday the 26th she had Markus Hohenwarter, the father of GeoGebra and the chief developer Michael Borcherds on for an hour discussing the past, present and future of GeoGebra. She recorded the session and it's available online.
What surprises me is that I still run in to teachers that have never heard of GeoGebra -- here you have free, open-source math software that almost any computer can run, it's multi-lingual, it's being used worldwide at all levels and has thousands of lesson plans and activities available on its wiki. And yet today I spoke to two Masters students who had never heard of it.
In Ontario, it's problematic since we (well, public and Catholic schools) have software purchased for them by the province and that set includes Geometer's Sketchpad. Now, GSP is an extraordinary program and we owe a great deal to Key Curriculum Press and Nick Jackiw but the development and growth of GeoGebra is a reflection of our brave new world -- collaboration on a global scale, the harnessing of our energies to support people we will never meet. What I do in my classroom can be given (instantaneously) to a classroom in Thailand, Kenya or Uruguay... and vice versa.
So how do we spread the word more effectively? How do we ensure that every preservice and practising teacher knows not only of its existence but also the community already formed?
And, most importantly, how can we port it on to an iPhone? :)

What do you think re: what Nick Jackiw said today re: GeoGebra?

For those that weren't in the audience, Nick basically re-iterated the comments he made to the CMESG earlier this year http://textsave.de/?p=27157
There are two sides to every story and I am waiting on a reply from the folks at GeoGebra before I draw any conclusions.
I was asked if I would change my use & promotion of GeoGebra should these claims be substantiated. I think the momentum it exhibits internationally (particularly at the grass-roots, classroom level) speaks to a need (pedagogically and otherwise) that is not being answered by any other tool or community. I am cautiously optimistic that Nick's issues can be addressed.

Thanks for cross-linking my CMESG post -- more coherent than my verbal response to Jesse's question Tuesday.

For your own thinking, re "free:" I imagine the Ontario Sketchpad license cost is a matter of public record there since it's Ministry-provisioned. Look it up and compare as an annual cost to your best estimate of the cost of the public effort expended by OISE math ed. faculty and associates on GeoGebra Canada promotion this year. Ontario taxpayers are spending a lot more on GeoGebra promotion this year than they to provide Sketchpad to every school and every school student at home across the province. That's "free?"

In terms of "two sides to a story," I also look forward to a reply from team GeoGebra. So far, they've been silent. In terms of "substantiating claims," please keep in mind that at least my lettered, CMESG claims are evidence-based, not merely rhetorical or personal opinion.

Best regards...

So you want to hack your OneNote Class Notebook

Taking a brief break from my "Getting Started with OneNote Class Notebook" series (you can start that one here )... This is a little advanced so if you're not comfortable setting permissions inside of Office365 you may want to avoid this.  Or set up a Class Notebook to play with so that it doesn't affect any existing Class Notebooks.  Yeah, the latter is a good option. One of the great powers of OneNote is that you can do some really neat permissioning of the Section Tabs. When the Notebook is created, of course, it gives you an "open permissions" on the Collaboration Space and student-read-only on the Content Library.  And then each student space is wide open to each individual student. But we've found that occasionally you want to mix up the permissions a little.  For example, you could create a space in a student section for your private notes that the student couldn't see, or maybe you want a tab in the Collaboration Space that students cou

Desmos, OneNote & Replay

So using Desmos activities are a great way to encourage exploration and discussion in math class -- if you haven't tried them, I encourage it.  They're collected at  https://teacher.desmos.com/  But ... Desmos doesn't give you quite enough.  It doesn't have a way of capturing the work that the student does within their space, and it doesn't allow for annotation of class contributions as we come together to discuss.  Well, not surprisingly, OneNote comes to the rescue.  Using the Windows shortcut Windows-Shift-S it is really quick to snag the Desmos screen and pop it into a waiting OneNote page.  From there, we can grab our pen and (using wireless projection) talk about what all the different responses mean and where to go from there. (An aside : one of the nice features of Desmos activities are the way you can hit PAUSE and it will pause all the screens of the students working.  I always give them a heads up "10 seconds to pause..." and it's refr

Equation Editor comes to OneNote (Win10)

Folks have been waiting a while to get Equation Editor into OneNote (Win10 version... it's been in 2016/Desktop for forever). Now, the funny thing is this won't make a huge deal for me. I tend to just write my equations out, and if it's for more serious distribution I tend to write it in Word.  But for others, this may improve the way they work in OneNote.  And I also think I'm not allowed to call it Equation Editor, but I'm going to ignore that. Make sure you've updated your OneNote (go to the Store and check for any Downloads & Updates). I recommend folks visit the Store regularly to get any updates. I'm never sure how often it looks for updates on its own and Microsoft has moved to a continual, if gradual update process for all of its apps. To start entering equations, click on the INSERT ribbon and then on EQUATION.  You may think, "why not just click on the Math button?" but that is to translate digital ink or text writing into a mat
