Quality and rate of drawing of blind children

Abstract

For a blind child the journey to a completed drawing is rather long, and much time should be dedicated to the development of the skill. Blind children are able to master the basics of drawing and so increase their successfulness in those curricular fields that rely, among other things, on drawing, too. Particularly the field of junior school mathematics abounds with the contents which are not suitable for mere oral explanations but require visual presentation. Such contents are, for example: line and field (curve, straight line, open and closed line), line segment, perceiving and drawing rectangles, squares, triangles, parallel and vertical lines, angles. The aims of the research were to evaluate the quality and speed of drawing of blind students and to determine whether there are significant differences between drawing on a wax board and drawing on a positive foil. The quality and rate of blind students' drawing were assessed by the use of the Luria-Nebrasca neuropsychological battery for children (LNNB-C, Golden, 1987), items 21 to 32. The results of the research showed that the quality and the rate of drawing of blind students are much better when positive foils are used in comparison to traditionally used wax board.

Put do nastanka crteža slepe dece je prilično dug, ali razvoju ove veštine potrebno je posvetiti vreme. Slepa deca mogu da ovladaju osnovama crtanja i da tako povećaju uspešnost u određenim nastavnim oblastima koje se oslanjaju i na crtanje. Naročito razredna nastava matematike obiluje sadržajima koje nije dovoljno verbalno objasniti, već i pokazati na reljefnom crtežu i nacrtati. To su npr. sledeći sadržaji: linija i oblast (kriva i prava, otvorena i zatvorena linija), duž, uočavanje i crtanje pravougaonika, kvadrata, trouglova, paralelne i normalne prave, ugao. Ciljevi ovog rada su: proceniti kvalitet i brzinu crtanja kod slepih učenika i utvrditi da li postoje značajne razlike u crtanju na voštanoj tabli i pozitivnoj foliji. Kvalitet i brzina crtanja procenjeni su pomoću Lurija-Nebraska neuropsihološke baterije za decu (LNNB-C, Golden, 1987), ajtemima od 21 do 32. Rezultati istraživanja su pokazali da su kvalitet i brzina crtanja slepih učenika znatno bolji na pozitivnoj foliji u odnosu na klasično nastavno sredstvo - voštanu tablu.
