GEOGEBRA FOR PRESENTING AND INTERPRETING GROUPED DATA AND SOLVING PROBLEMS OF PHYSICS

Abstract

Today is highly speed progressing the computer-based education. The computerbased education allowes educators and students to use educational programming language and e-tutors to teach and learn, to interact with one another and share together the results of their work. The computer-based education is done possible by special electronic tools among which the most important are the mathematical programmes. In this paper we will be concentrated on the use of GeoGebra programme for solving statistical problems. GeoGebra affords a bidirectional combination of geometry and algebra, by the mean of which we can see and handle both geometric objects and their corresponding algebraic objects. Geogebra is useful for organizing, presenting and analyzing data. Its advantage is that we can show different types of data presentation in one box. One simple example is brought through this paper that shows that GeoGebra allows to make three data presentations(histogram, stem and leaf plot and line plot) in one box, or in one figure. Even, we can add other presentations in the same box. This feature of GeoGebra facilitates our work for analyzing and interpreting the data under study. There are many more other applications of GeoGebra in the statistical problems, likewise in the other fields of mathematics. In addition we have brought an example from physics of how can be used GeoGebra for finding the center of mass(centroid) of a picture(or system of polygons). Surely, the passionate work of many GeoGebra users will result with a very rich fund of GeoGebra virtual tools, of examples and experiences that will be worldwidely available for many teachers and practioners and, GeoGebra serve as effective tool in problem-solving.
