Abstract
Haptic exploratory movements of children with visual impairment are of educational and social interest because they can provide information as to how these children perceive the world around them in a tactile way, as well as how they construct knowledge. In this paper we analyzed the movements of primary school students with visual impairment, without accompanying problems, during their haptic exploration of objects, recognition of objects’ surface shape, and comparison and measurement of objects’ surface size. All data was video recorded. Every child, when individually met, carried out two activities. The results showed that the students recognized the shape of objects’ surfaces. Although they were able to compare the objects’ surface size when one object was longer and wider than the other, they encountered difficulty when each object differed in a different dimension (e.g., one was longer and the other one was wider). Moreover, students encountered difficulty during measuring the dimensions of the objects.
