Modeling a geometric locus problem with GeoGebra
Journal Title: Annals. Computer Science Series - Year 2009, Vol 7, Issue 2
Abstract
În rezolvarea unor probleme de loc geometric analiza, modelarea, studiul cazurilor particulare ce ajută la intuirea soluţiei poate atrage din partea rezolvitorului un efort de lungă durata. În acest sens, folosirea unor programe specializate pentru modelarea unor fenomene matematice, în genere transformări geometrice în plan, este un instrument acceptat şi folosit din ce în ce mai mult. În cadrul lecţiilor de predare-învăţare a matematicii, implementarea investigaţiei desfăşurată pe platforme de geometrie dinamică precum Geogebra poate atrage definirea unor noi metode de predare-învăţare “nonstandard”, metode ce sunt acceptate ca metode de graniţă ce folosesc instrumentul informatic în strânsă legătură cu demersul matematic al metodelor clasice. Vom numi acest demers “infogeometria dinamică”.
