In its introductory part the fundamental types of epistemology obstacles are formulated. The cognitive conflict and its role in overcoming these obstacles are analysed in the following section of this research. Finally, the authors focus on research methodology and the results of the three-year research project. The problems are illustrated by means of real experimental interviews.application/pdfobstacleconcept of infinitycognitive conflictfolyóiratcikkOpen AccessJiří Cihlář, Petr Eisenmann, Magdalena Krátká and Petr Vopĕnkahttps://doi.org/10.5485/TMCS.2009.0240Teaching Mathematics and Computer Science27Teach.
