The Teaching, Mathematics
2012 unpublished
The paper presents the key elements of a model for in-service teachers training. An educational module about parabola as geometry object is the illustrative part of the model. The inclusion of dynamic geometry system applets allows some properties of the parabola to be established by examining dynamic constructions. Starting with the focusdirectrix definition, the reflective property of the parabola has been proven and the equation of the parabola is worked out. A comprehensive comment on
