Geogebra

   There are two sites where people can find, use, and make and share visual, interactive math activities:   Geogebra and Desmos.   With my finite time and so many pots on the fire, I decided in January that I'd get to know Geogebra, primarily because it is more officially and formally OER; pretty much everything is CC-BY.   

   While there are some tutorials it's not really easy to figure things out (it was weeks before  I found out that I could click on any app in the right place and find the "construction protocol,"  which lists the steps the author did to create the app)... but I found this

 https://www.geogebra.org/m/k55KxaVx#material/hpuY9TtF 

  where students place assorted numbers in scientific notation on anumber line.   I modified it for students who need fluency in understanding negative numbers... so they can automatically "feel" that -10 is lower than -1...   

https://www.geogebra.org/m/T9jPesSF   

    I've had lots of great help from folks on twitter -- including one Steve Phelps who sent me screencast how-to's, and who will be coming to Champaign in June to do a 2-day workshop (free) -- and we've still got a few spots left if anybody's interested.   Champaign is in central Illinois ...https://www.eventbrite.com/e/geogebra-workshop-at-parkland-college-tickets-45538951229

Hi Susan,

I also use a lot of Geogebra in my teaching. Thanks for sharing the information.

Are you aware of any formal research done about how effective using Geogebra is for math teaching?

I'm doing a project related to this and have a hard time finding anything.

The workshop sounds so interesting to attend. I would love to go if we are not so far away......

I don't know of formal research about Geogebra -- but I suspect there might be some about incorporating visual elements (I wonder if people have done research w/ Mathematica which has been around longer). 


I *know* what an incredible difference working from visual/concrete to abstract can make for students who aren't fluent w/ attaching meaning to math symbols (for so many possible reasons including dyslexia, learning to just memorize in the past...)

Agree!
