Who are you, what are you doing?
My name is John Golden, I’m a mathematics education prof at Grand Valley State University, in western Michigan, USA. I teach future K-12 teachers, mathematics courses, and mentor student teachers.
When did you first try GeoGebra?
Fall 2009. I loved dynamic geometry, but had very little use from my students other than what I asked, since their access was limited. An open source program was a dream come true.
What do you hate in GeoGebra?
Nothing! I miss recursion a little bit, and wish the custom tools were a little more flexible, but new features get added literally faster than I could wish for them.
What do you love in GeoGebra?
So many features to love. The heart of it is the strong connection between geometric and algebraic representations. As an application, the unbelievable ease to get a new user starting is amazing.
What are the GeoGebra related activities you participate?
I use GeoGebra with students, both as a super-calculator and geometric constructer and for created activities. I help train teachers to use the program, and support local and web users via email and Twitter (@mathhombre). I use it for my own mathematics solving, and just to play.
