The article discusses the factors that affect the development of speech in older preschool children, and the place the educational environment takes in this process. A brief overview of the history of the concept of educational environment in Russian and foreign pedagogy and educational psychology is given.
Aim of the study. The method of assessing the educational environment CLASS is considered, such a component of the CLASS methodic as methodological support is analyzed. On the other hand, the authors give a brief description of the child’s language development up to the senior preschool age and conclude that for the most effective assessment of speech development at this age, it is necessary to use elicited narratives (that is, stories told by the child based on a series of pictures). The literature overview of the interrelations between the educational environment quality and the child’s speech development showed that contradictory data were obtained. The hypothesis of this study was the assumption that such a parameter of the educational environment as Methodological support would affect the development of speech in older preschool children.
Sample. The study involved 261 preschoolers (49,4% of boys) aged 5–6 years, pupils of 26 senior groups of kindergartens in Moscow. To test the hypothesis, two groups of preschool educational institutions were identified using the Mann-Whitney test: with high and low quality of methodological support, and then, using ANOVA, the speech parameters of children from these two groups were compared.
Results. As a result of the study, for the first time in the Russian sample, the results were obtained that well-organized methodological support in a preschool educational institution contributes to the better development of both lexical and grammatical indicators of speech and the ability to compose a coherent statement (narrative). The article draws conclusions both about the limitations of the conducted study and about possible ways for further research.
