In the development of artistic expression a child has the need for constant changing of the conent of his work. That need is deriveing from an active cognition and expression of its comprehension. Artistic expression can be found in diverse variations but in essence it is based on specific and permanent rules. The true value of artistic expression is not that the child can express in a recognizable way a figure or simbol so it resembles the real shape, but more what the child sees, finds or discovers by it's own. Formentioned rules are changed during child development according to functional reasons, and that creates requirements for a gradual insight in the wolrd that surrounds them, and at the same time being in accordance with their inner world. Forms of artistic expresson are not just signs of developmens in the inner mind of the child, they also perform a feedback that empowers their percepcion and visualisation giving them the ability to form and create. Children create atristic expression open-mindedly, sincerely and full of enthusiasm. A child's colourfull drawing is in fact its inner projection of his moods and feelings. Colours reveal a childs emitional life, the lines and figures his level of self-control, spatial dimensions are pointing to the level of environment influence. While at free play, children use colours of paralel streems and coats. Children are paiting different, and at the same time playful and dampened colours, on the whole surface. The way the colours are applied, the different widths and variations of colours can point to an external and simple estetic value. The contemporary Art education requires the development of free creativity according to its individual interests, tendencies and abilities of drawing for each individual child. It is of importance and a necessity knowing all characteristics of artistic expression in order to approach the childs creative process with knowledge and the right understanding.
