Children's artistic expression begins spontaneously and with the child’s desire to explore and create. Children realise their creative potential through various artistic activities that involve a range of different materials and means. Children are beings who need freedom to explore and discover themselves, their emotions and feelings and the state they are in at th moment of creation. Through artistic expression, they develop visual-spatial intelligence, imagination, aesthetic perception,and specific skills for artistic expression. Preschool teachers play a major role in the development of children’s creativity. They provide high-quality spaces, needed materials and a wealth of motivating stimuli. It is important to accept and encourage the creative expression of children’s ideas, experiences and feelings in various artistic fields and mediums of expression. In addition, a preschool teacher plays an important role in encouraging children’s independence, work habits and perseverance, as well as documenting children’s artistic creativity and developing their artistic skills. The success of early childhood and preschool art activities depends on the competence of the preschool teacher. To be successful, preschool teachers must be familiar with the psychological and artistic development of children, their individual abilities and needs, and the methodology of teaching preschool children. It is important that a preschool teacher respects the interests and needs of the children and gives them freedom to create. The preschool teacher’s role as an observer and leader of activities guides and encourages the children to produce high quality work. The quality of a preschool teacher’s work is reflected in the ability to respond to the children’s unplanned and real activities in specific situations. Children must not be interrupted or disturbed during artistic expression, otherwise their creativity and the ideas they have come up with will be damaged.
