Mastering the complexity of teaching takes time and requires a lot of practice and sustained effort. Observing and reflecting about actual lessons can play a critical role in the journey to becoming a proficient teacher. It provides a direct window into the classroom, from which practitioners can analyse and reflect about teaching in order to hone their craft.

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.
