Background. _e individual’s ability for self-development is the modern day priority in education. _e main prerequisite for the development of this ability is self-organization which is considered to be one of the future’s most in-demand competences. It seems necessary to study the conditions for its development at the initial stage — at preschool age, in particular, in a kindergarten, where children spend a signi`cant part of their lives. Objectives. _e study aims to explore the practices of educational systems as an environment to develop self-organization of preschool children at the Waldorf kindergarten with the educational programme “Beryozka” (V.K. Zagvozdkin, S.A. Trubitsyna), where independent and cooperatively-shared activity with an adult prevails (independent and cooperative activity — ICA) and at the most common kindergarten “From Birth to School” (N.E. Veraksa, T.S. Komarova, E.M. Dorofeeva), where activities organized by adults (AOA) predominate. Sample. _e study involved 28 normatively developed children from Moscow kindergartens aged from 6.4 to 7.2 years (13 girls and 15 boys). Half of the preschoolers were brought up in the groups of the Waldorf kindergarten operating under “Beryozka” programme, the other 14 children were from the kindergarten operating under the mass program “From Birth to School”. Method. To evaluate the development of self-organization in children, involved in diaerent educational programmes, a range of methods were used. _ese included structured observation, structured analysis of the programmes, questionnaire, and an experimental method for assessing the level of self-organization in preschoolers based on a modi`cation of the methodology for assessing educational activity (Repkina, Zaika, 1993) and on diagnosing the features of self-organization (Ishkov, 2011). Two diagnostic situations included novel productive activity in the “Sewing on buttons” technique with a demonstration as instruction and the outdoor game “Hoops and bags” with a verbal instruction. Statistical dataprocessing was carried out with the SPSS Statistics program. Results. _e level of children’s self-organization in diaerent educational systems varies signi`cantly according to both the overall assessment and individual criteria. _e group of independent and cooperatively-shared activities with an adult (ICAA) included twice as many highly self-organized children as the group with a predominance of classes and activities organized by an adult (AOA) (85.7/92.9% vs 42.8/50%). In the “Game with Task” test, the diaerences between children in the AOA and ICAA groups were more pronounced than in the “Productive Activity” test. _is stage showed that them ICAA group had a signi`cantly higher level of Goal Setting (100%) and Self-Control (78.6% and 92.9%), while in the AOA group about half of the children reached a high level in both tasks (Goal Setting 57.1% and 50%, Self-Control 57.1%). In the ICAA group, a high level of Planning was also noted in the majority of children (92.9%). At the same time, according to the criteria “Analysis of Situation” and “Correction”, in the AOA group, every `ch child (21.4%) showed low level, whereas no low level was registered in the ICAA group. Conclusion. _e educational process in the form of joint / free activity enhances the development of self-organization of preschoolers better than a tightly organized schedule of classes. Rhythmic alternation of concentration on the leading adult and independent activity allows the child to remain active longer and more consciously.
