SAŽETAK:
Razlomak je jedan od osnovnih pojmova kojima bi učenici trebalo da ovladaju u okviru nastave matematike u mlađim razredima osnovne škole. S obzirom na nivo razvijenosti kognitivnih struktura učenika ovog uzrasta i potrebu za očiglednom nastavom, višestruke vizuelne reprezentacije doprinose boljem razumevanju i shvatanju pojma razlomka. U prvom delu rada bavili smo se prikazom konkretnih primera podele celine na polovine uz korišćenje softvera GeoGebra, dok smo u drugom delu analizirali rezultate istraživanja sprovedenog sa ciljem određivanja stepena zastupljenosti obrazovnog softvera u nastavi matematike u nižim razredima osnovne škole i stavova učitelja prema njemu. Uzorak istraživanja činilo je 108 učitelja sa teritorije Republike Srbije. Rezultati ukazuju da za veliki procenat ispitanika obrazovni softver predstavlja terminološki nedovoljno razjašnjen pojam. Rezultati su takođe pokazali da, iako većina ispitanika smatra da obrazovni softver doprinosi povećanju kvaliteta znanja učenika, veoma mali deo njih ga je i koristio u nastavi matematike, a obrazovni softver GeoGebra, koji je u fokusu našeg rada, predstavlja nepoznanicu za veći deo ispitanika, iako svi koji su ga koristili imaju pozitivan stav u pogledu njegove korisnosti i funkcionalnosti u nastavi matematike.
