Within the context of research called "Changing the culture of educational institutions--a way to qualitative changes in preschool education", implemented within a three year period and, because of the needs of this work, this paper reports the results of the research performed in the first year. The work was carried out with emphases on preschool teachers' training for the process of research and improvement of their own practice by creating a stimulating environment of an educational institution which is attended by children ranging from one to six/seven years of age (preschool period). This practice should be in accordance with children's nature and should change continuously, being in coordination with children's needs, environment and education. We hold that there is no theory that identifies only the needs to be learned and then applies that in practice, but rather, that a stimulating environment is also being created and built jointly by doing and participating in continuous research of educational practice. The emphasis is on shared direct research, its discussion, continuous changing of one's own environment and providing children with more freedom, games and learning, which constitutes qualitative living.
