The Search for Fidelity in Geometry Apps: An Exercise in Futility?

Abstract

As the use of mathematics apps in classrooms becomes more prevalent, robust research into their effectiveness is required to inform best practice regarding their use. This is particularly the case for Geometry apps where accurate and dynamic representations are critical in enhancing mathematical learning. This paper provides findings from an initial critique of 53 Geometry apps. Early findings indicate that the majority of these apps were limited in their ability to assist students in developing Geometrical conceptual understanding; however, all is not lost as a number of apps were highly appropriate.
