New contents of mathematical education in primary school for visually impaired children

Abstract

To regular studying of elementary geometry by children visual impairments should be given much more places in primary school, than it takes place now. In primary mathematics contents necessarily there should be tasks for change of geometrical objects, their spatial transformation. Necessity of inclusion of such tasks proves to be true the proved in psychology thesis about similarity of spatial thinking structure to structure of geometrical transformations group. According to which skills of the child to operate by the spatial images it will be coordinated to his ability to carry out the certain set of geometrical transformations. Inclusion of geometrical transformations to the contents of education in primary school for children with visual impairment has for their development very important correctional value. Mastering by skill of performance of geometrical transformations, mastering of their properties and laws will help the children to compensate lacks, incompleteness of their sensual experience, a significant place in which just and belongs to knowledge and the skills basing on spatial properties of the surrounding reality. Pupils of primary school accessible to mastering are first of all such geometrical transformations, as symmetry of various kinds, rotational displacement, parallel transposition and also their compositions.
