Prispevek govori o pouku geometrije v 1. letniku gimnazije, pri čemer povezuje tri možne pristope: klasično (evklidsko) geometrijo, analitično in geometrijo transformacij. Pri tem je mogoče zelo učinkovito uporabiti programe dinamične geometrije. Najprej se zelo na kratko opredeli osnovne pojme v posamezni zvrsti geometrije, potem pa na praktičnih primerih z uporabo programov The Geometer’s Sketchpad, RiŠ in Cabri Geometry II.Plus pokaže povezovanje različnih pristopov pri obravnavi snovi. Programi dinamične geometrije dijakom omogočajo globlje razumevanje in povezovanje snovi, česar pri klasičnem pouku pogosto ne dosežemo v tolikšni meri.
Abstract
The article covers the topics of teaching geometry in grade 1 of our high school (gymnasium). It’s about teaching geometry from multiple perspectives: synthetic geometry, analytic and coordinative geometry and geometry of transform with the use of the computer programs of dynamic geometry. In the introduction it highlights the fundamental ideas of each of the perspectives, then the author presents some examples with the use of the programs The Geometer’s Sketchpad, RiŠ and Cabri Geometry II.Plus. Some concrete examples are presented how different approaches can be linked up when teaching geometry. Such a way of teaching deepens and enables understanding of geometry in the most interesting way.
