VIZUELIZACIJA REŠAVANJA ZADATAKA SA NIZOVIMA BROJEVA: STATISTIČKO POREĐENJE DVE METODE
VISUALIZATION OF SOLVING PROBLEMS WITH SEQUENCES OF NUMBERS: STATISTICAL COMPARISON OF THE TWO METHODS

Summary/Abstract: The twenty-first century has brought the growing use of information and communication technologies in manyspheres of human life. Also in education. In the learning process, students are increasingly focused on the use ofmodern technologies and software packages. Exploring the quality of maths teaching in primary school, we foundstudents' knowledge of using modern technologies but also the lack of visual-logical approach in solvingmathematical problems. In this paper, we show how the establishment of figurative numbers and selected examplesthat demonstrate the observation of legality, can direct students to a visual-logical approach to solving tasks withsets of numbers. We organized a three-hour exercise in experimental and control group, during which theexperimental group was working with figurative numbers and the control group with selected examples. On thepre-test both groups showed a low degree of ability to observe legality among the numbers. On the post-test, bothgroups achieved progress compared to the pre-test, although the experimental group achieved greater progress.The research has shown that dealing with figurative numbers and selected examples that demonstrate theobservation of legality, contributes to the development of pupils' abilities to perceive the laws of numbers and toapply the laws observed to solving problems with sets and arrays of numbers
