Özet

In this study, we tested the van Hiele levels of the 8th grade Turkish students and examined their classification preferences (hierarchical or partitional) about relationships between some quadrilateral pairs. We also discussed the effectiveness of the materials (geo-stripes, dot paper and geo-boards) used for teaching the topic of quadrilaterals in terms of the students' classification preferences. The results indicated that most of the students were at van Hiele level 2 before starting their high school education and the students generally chose partitional classification. Therefore, we concluded that the materials had some limitations and were not adequate for learning the topic.
