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.
ZDM is one of the oldest mathematics education research journals in publication. The journal surveys, discusses, and builds upon current research and theoretical-based perspectives in mathematics education. In addition, it serves as a forum for critical analysis of issues within the field.
All the papers published in the journal?s seven annual themed issues are strictly by invitation. These papers are subject to an internal peer review by selected members from the editorial board as well as an external review by invited experts. The journal targets readers from around the world in mathematics education research who are interested in current developments in the field.
