Proper correlation between perception of pieces of art and practical participation in production of them in the system of artistic education can - as has been shown in an experiment - significantly determine not only the ability for creative work but the development of a schoolchild's personality as a whole. Whenever there is a gap between the theory and practice, when art is taught in the absence of critical means of assessment and without proper account of the age specificity of perception and cognition, there is a serious danger of appearance of egocentricity, of peremptory judgements, of inadequate development of a number of ethical notions.
