Description:
This paper brings information on dynamic multiplatform mathematical software GeoGebra produced by Markus Hohenwarter in 2002 for learning and teaching mathematics, available free on web in 45 languages. GeoGebra enables production of self-standing dynamic worksheets as interactive java applets embedded in html pages presenting dynamic constructions and interactive calculations on Internet. Thus it is enhancing available powerful electronic tools suitable for production of instructional materials in on-line maths education. Several possibilities are presented on how this useful utility might be used in e-learning solutions as a dynamic interactive platform for calculations and drawings.
