GeoGebra

GeoGebra

GeoGebra is an opensource, multi-platform dynamic mathematics software for learning and teaching.

Specifically, this application is dynamic mathematics software for all levels of education. It joins arithmetic, geometry, algebra and calculus. It also provides multiple representations of objects in its graphics, algebra, and spreadsheet views that are all dynamically linked.

Constructions can be made with points, vectors, segments, lines, polygons, conic sections, and functions. All of the constructions can be changed dynamically. Elements can be entered and modified directly on screen, or through the command line. GeoGebra can use variables for numbers, vectors and points, find derivatives and integrals of functions and has a full complement of commands like Root or Extremum.

Teachers can also use GeoGebra to make conjectures and prove geometric theorems.

GeoGebra has won many international awards:

  • EASA 2002: European Academic Software Award (Ronneby, Sweden)
  • Learnie Award 2003: Austrian Educational Software Award (Vienna, Austria)
  • digita 2004: German Educational Software Award (Cologne, Germany)
  • Comenius 2004: German Educational Media Award (Berlin, Germany)
  • Learnie Award 2005: Austrian Educational Software Award for "Spezielle Relativitätstheorie mit GeoGebra" (Vienna, Austria)
  • Trophées du Libre 2005: International Free Software Award, category Education (Soisson, France)
  • eTwinning Award 2006: 1st prize for "Crop Circles Challenge" with GeoGebra (Linz, Austria)
  • Learnie Award 2006: Austrian Educational Software Award for "Wurfbewegungen mit GeoGebra" (Vienna, Austria)
  • AECT Distinguished Development Award 2008: Association for Educational Communications and Technology (Orlando, USA)
