Ethnochoreologist dr. Ivan Ivančan based on the division of the ethnographic area of Professor Milovan Gavazzi, continues to study and research folklore according to four dance zones: Alpine, Adriatic, Dinaric and Pannonian. Ethnochoreology in Croatia became known and researched only with the arrival of Ivančan in 1954, and with its artistic and scientific work it became known to the Croatian public for more than half a century. He has written and published numerous books that have encouraged his colleagues to continue researching an area about which little is known. The most deserving person for nurturing children's folklore from an early age went to Goran Knežević, artistic director, choreographer and organizer of the seminar cycle "Children's folklore creation and application of folklore in working with children", which is just one of the seminars where Knežević conveys authentic sources and knowledge from both oral and written submissions. This work represents a description of folk dance, structure and style, and the division of children's folk dances according to two ethnographic areas: the Adriatic and the Pannonian. It describes the stage application of folklore in working with children and the variety of folklore forms that are suitable for the preschool period: counting games, mockery, lullabies, children's singing games, children's dances and walking or singing carts. It emphasizes the influence of folk costumes and traditional clothing and shows the diversity of customs, culture, traditions according to the broader form that includes dance zones and the narrower that refers to the application of dance in villages and surrounding places. Previous research shows insufficient research of folklore sources and traditional way of life, which can be seen in the literature: the richer cultivated area belongs to the Pannonian dance zone, while significantly less material is available on the Adriatic. Further professional and scientific research is needed on the valuable traditional heritage that deserves to be at the highest level of appreciation and respect for cultural awareness and its expression, which is emphasized by the document National Curriculum for Early and Preschool Education.
