Cím:Interactive dynamic tests for evaluating the development of spatial abilities in high school / Budai László
ISSN:1584-286X 1843-441X
Megjegyzések:In the last 10-15 years the number of studies examining spatial abilities of students has increased rapidly. The development of the spatial ability system components is important since these skills are used in everyday life and in order to reach our goal (position) people need good spatial perception in many cases. GeoGebra is a suitable and effective tool for developing these abilities. New methods for measuring these abilities can be developed that would be better adapted to today's needs. The dynamic and interactive adaptation of available GeoGebra tests for measuring spatial abilities would place these measurements on a new ground. However, there are many unanswered questions. The technical background, results and experiences of pilot a test of these methods are presented here.

Cím:Use of GeoGebra in teaching about central tendency and spread variability / Pellumb Kllogjeri, Adrian Kllogjeri
ISSN:1584-286X 1843-441X
Megjegyzések:In data analysis are used graphs, tables, and numerical summaries to study the variation presentin data under study. Graphs are effective visual tools because they present information quickly and easily.Graphs are commonly used by print and electronic media and, data can be better understood when presentedby a graph than by a table because the graph can reveal a trend or comparison. Graphs display the relationshipbetween variables or show the value spread of a given variable or phenomenon. Measuring the central tendencywe identify the most representative value in a set of data. Mean, median and mode give different perspectivesof a data set's centre, but a data description is not complete until the spread variability is also known. Thebasic numerical description of a data set requires measures of both centre and spread. In this paper we willbe concentrated on graphical representation of data collected from a population. A useful tool to get suchnice visual representations is GeoGebra. GeoGebra is an interactive geometry system and, by the use of itsvirtual tools, we can do constructions with points, vectors, segments, lines; we can construct histogram andgeometrically show the positions of the median and quartiles [4]. GeoGebra provides numerical calculationsfor the measures of data centre and spread. GeoGebra software is very useful and helpful for teachers andstudents to graphically present data and easy understand and interpret them [6]. Also, GeoGebra is dynamicmathematics software for schools that joins geometry, algebra, and calculus. Using this dynamic feature in theteaching hour of statistics, the students have a better and fuller understanding about data measures and dataspread.
