GeoGebra introduction
for teachers
The following videos introduce different aspects of GeoGebra. They are
meant for newcomers not knowing GeoGebra on beforehand.
GeoGebra is a freeware, non-profit program for teaching math to
students, especially in the age group 12-20. You can install GeoGebra from http://www.geogebra.org/cms/download . GeoGebra is
widely spread across the world, and it is translated into more than 60 languages.
Present (Oct2014) version 5.0 includes CAS and 3D-drawings.
You can find thousands of videos about GeoGebra, se YuoTube
or http://www.geogebratube.org/ . I here try to cover
important aspects from the syllabuses in 17 videos with video 1 as the very
first introduction.

etc. to Frede Dybkjær, mail frede@dybkjaer.com .
If you represent many teachers, then you can have a CD sent by letter
containing all of this.
