Criterion-Referenced Reliability Indices Associated with the van Hiele Geometry Test
Mary L. Crowley · Journal for Research in Mathematics Education · 1990
Recently the work of Pierre M. van Hiele and Dina van Hiele-Geldofhas gained prominence in the study of the teaching and learning of geometry. Their three-part model (a) describes five sequential and discrete levels learners pass through as geometric thought develops, (b) discusses the nature of insight into geometric concepts, and (c) presents a guide to the development of geometric lessons. A detailed description of the complete model can be found in Crowley (1987).
