Guest blog by Dr. Jeremy Roschelle, Digital Promise, @roschelle63 Summary: When integrated with curriculum and pedagogy, visual representations that change in time can improve students’ conceptual understanding of mathematics. To understand mathematics, students need to connect ideas. For example, the slope of a line is often given as a number — the m in y…
"GeoGebra ist eine kostenlose dynamische Mathematiksoftware, die für SchülerInnen aller Altersklassen geeignet ist und auf allen Betriebssystemen läuft. GeoGebra verbindet Geometrie, Algebra, Tabellen, Zeichnungen, Statistik und Analysis in einem einfach zu bedienenden Softwarepaket, das bereits mehrere Bildungssoftware-Preise in Europa und den USA gewonnen hat."
GeoGebra is dynamic mathematics software for all levels of education that joins arithmetic, geometry, algebra and calculus. On the one hand, GeoGebra is an interactive geometry system. You can do constructions with points, vectors, segments, lines, conic sections as well as functions and change them dynamically afterwards. On the other hand, equations and coordinates can be entered directly. Thus, GeoGebra has the ability to deal with variables for numbers, vectors and points, finds derivatives and integrals of functions and offers commands like Root or Extremum. These two views are characteristic of GeoGebra: an expression in the algebra view corresponds to an object in the graphics view and vice versa.
