Veronika Bočková, Gabriela Pavlovičová:	Solving Geometric Tasks by 9th Grade Pupils and Using GeoGebra Software
Full paper

Abstract: Geometry is one of the most important branches of mathematics education in Slovakia and abroad. According to our experiences, pupils often have difficulties solving various geometric tasks. It can be caused by a lack of pupils´ knowledge of geometry or the low levels of their mathematical competencies in geometry. For these reasons, the research focuses on evaluating six geometric tasks solutions at various levels of mathematical competencies. The research confirmed our assumptions that 9th-grade pupils have significant problems with solving geometric tasks at the higher level of mathematic competencies. There are a lot of opportunities to support the development the mathematical competencies in geometry. One of the possibilities for it is to use various dynamic geometric software. Therefore, after evaluating the geometric tasks, there are offered the solutions of geometric tasks by using the GeoGebra software in the article.
