RT Journal Article SR Electronic A1 NOCAR, David A1 ZDRÁHAL, Tomáš T1 EFFICIENCY OF THE DYNAMIC GEOMETRY SOFTWARE FOR SELF- EDUCATION ON ONE GEOMETRIC CONCEPT JF Trends in education YR 2016 VO 9 IS 1 SP 198 OP 204 DO 10.5507/tvv.2016.027 UL https://tvv-journal.upol.cz/en/artkey/tvv-201601-0027.php AB The paper deals with the research project concerning the efficiency of GeoGebra for self-education on the geometric concept regular tessellations to compare with the traditional methods (paper and pencil or using paper models). The project was provided on the sample of more than 70 students of non-mathematics bachelor studies. Our results point that GeoGebra (i.e. Dynamic Geometry Software) does not have to be all the time better than traditional methods, especially if it is used exclusively for self-education.
