Using the Turtle Tot Robot To Enhance Logo for the Hearing Impaired

摘要

This paper describes the Turtle Tot, a Logo powered robot that assists hearing-impaired students in making the transition from the concrete geometric movement of their bodies to the directed geometry of computer Logo. Also described is the process for leading students from describing the elements of their body movements to directing the Turtle Tot through computer Logo, to directing the on-screen turtle with Logo procedures. Through this process, students can explore directionality, basic geometry, language concepts, and logical thinking.
