Geometrijska interpretacija razlomaka primenom obrazovnog softvera GeoGebra

Abstract

Fractions are one of the basic mathematical concepts in the lower grades of primary school. Considering student’s level of cognitive thinking and their need for concrete teaching, multiple visual representations offer better understanding of fraction concepts. In the first part of the paper some models of dividing the whole into two halves using the GeoGebra software were presented. The second part of the paper presented the results of a study aimed to investigate to what extent educational software is present in teaching mathematics in lower grades of primary school. The attitudes of class teachers towards the use of educational software were analysed as well. The sample consisted of 108 teachers from the territory of the Republic of Serbia. The results have shown that a large percent of respondents did not completely understand the term educational software. In addition to this, the research results indicate that, although a majority of respondents believe educational software increases the quality of students’ knowledge, a very small part of them had a chance to get acquainted with the benefits of using GeoGebra software in teaching
