Abstract expressionism is a direction in art that arose as a combination of abstract art and expressionism. It is divided into two groups: action painting and colour field painting. The most famous painters of the colour field are Mark Rothko, Barnett Newman, Clyfford Still, while representatives of action painting are Willem De Kooning and Jackson Pollock, who is the main subject of this work. Pollock develops a new painting technique called action painting, which involves dripping, splashing and pouring paint onto a large canvas using various gestures and movements. The characteristics of his painting style are improvisation, dancing around the canvas, throwing and spilling paint, which is why he got the nickname ''Jack the Dripper''. This thesis presents Pollock's biography and an overview of his works of art. The legacy of Pollock's extraordinary works provides an immense potential for encouraging children's artistic creativity, which is confirmed in the practical part of this paper. In the following, it is explained to what extent artistic activities influence the overall development of children, the role of educators in encouraging children's artistic creativity is clarified and how works of art encourage children to be artistically active. For the purposes of this paper, the children from the kindergarten ''Proljeće'' showed with their own works what impression Pollock's works leave on them. The activities were conducted in four educational groups (nursery, junior, middle and senior groups). Based on children's works, a positive influence of works of art can be seen as an incentive for artistic activity, with the help of which children developed spontaneity, imagination and creativity.
