Description of Teaching Visually Impaired Children to Make Distance Judgments from a Tactile Map
Abstract: This article reports on two experiments that investigated 59 children's ability to estimate distances from a map. In Experiment 1, totally blind children, children with residual vision, and sighted children were given a map showing the position of three objects on a path, two of which were present on the actual path. The children were asked to use the map to work out the position of the third object. The visually impaired children performed less well than did the sighted children, and an analysis of the children's strategies indicated that the majority of visually impaired children did not know an effective way to work out distances from the map. In Experiment 2, the visually impaired children were given a brief training in how to calculate distances from a map and then they were retested. After training, the children's performance improved.
