Abstract

Quadrilaterals and their interrelationships are important part of school mathematics. The current literature about quadrilaterals piles up within three main categories of research focusing on: (1) Students’ understanding of and ability to identify quadrilaterals that cut across school mathematics and their interrelationships (e.g., Fujita & Jones, 2007); (2) van Hiele (VH) levels of geometric thought and how students fall into a variety of levels for different geometry topics (Jones, 2000); (3) The impact of technology-supported environments on student achievement. However, these categories of research fall short in explaining how to foster student thinking from one VH level to another. Therefore, this study aimed to investigate the core pieces of a technology-supported (Geometer’s Sketchpad (GSP)) instructional sequence that help to foster a deep understanding of the hierarchy of certain quadrilaterals (square, rectangle, rhombus, parallelogram, trapezoid) as students shift from one VH level to another.
