Geometry has always been regarded as one of the most important area in Mathematics. The van Hiele model is one of the renowned theories focusing on the teaching and learning of geometry. While GeoGebra is a free, open-source dynamic geometry software developed to assist the teaching and learning of Mathematics in general. This study investigated the effectiveness of van Hiele phases with GeoGebra in geometric transformations, particularly for the topic of rotation in geometry. Some of the Year 11 students who participated in this study were interviewed. The focus of the interview was directed at exploring the students' views on van Hiele phase-based learning, the use of GeoGebra and the thought processes on the topic. The development of the interview analyses yielded two emerging themes namely, the impact of van Hiele phases and the impact of GeoGebra as an instructional tool. Although the combination was mainly perceived as positive, there were also reluctance in accepting due to the readjustment needs of the concepts and applications of the tool itself.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
