Design of a logo environment for elementary geometry

One rationale for Logo programming is that students will learn geometry for utilizing concepts that aid them in understanding and directing the Logo turtle's movements. Research on this claim has yielded mixed results; however, an analysis of these research findings provides significant guidance in the teaching and learning of geometry with Logo. This article (a) reviews the body of research that led to the design of a new Logo environments tailored for elementary students' learning of geometry; (b) describes this environment, Geo-Logo, and its connections to this research corpus; and (c) presents empirical data from the first field test of the environment, which generally support the efficacy of the design.
