The main advantage of this approach is that it is not based on set theoretical, or combinatorial knowledge, hence it is more suitable for beginners and facilitates the transitions from level 0 to level 3. We also mention a few teaching experiences on different levels (lower secondary school, upper secondary school, teacher training, professional development, university students) based on this approach.application/pdfclassical probability theorygraph representationsVan Hiele theoryfolyóiratcikkOpen AccessGabriella Zsombori and Szilárd Andráshttps://doi.org/10.5485/TMCS.2013.0335Teaching Mathematics and Computer Science111Teach.
