The article is an attempt to analyze the anthropology of cognitive development and physical growth of children in a bilingual environment. Bilingual children who speak native Tatar and Russian learned to communicate Russian through a set of physical exercises. A diagnostic study was conducted among older preschool children in Tatarstan (237 children in the first three months of 2019). It was based on the criteria of connectivity: inter-sentence connection (ISC); semantic structure (SS); complex syntax (CS). It indicated that 67% of older preschool children showed no evidence of connectivity in statements made during the retelling of a fairy tale or writing a story on a given topic.
In the formative pedagogical experiment, a set of exercises was used to integrate physical and speech activity by the connectivity criteria. The study showed that work in the second (Russian) language created the Russian language environment and to some extent suppressed the interference of the native language. Activation of cognitive functions of the child in the second language, according to our observations, led to inhibition of these functions in the native language. However, on the whole, the pedagogical experiment demonstrated the effectiveness of integrated work as cognitive functions related to cognitive processes including memory, thinking, attention, imagination, perception have improved significantly in the second language for bilingual children. It was concluded that such work should take place in several stages: diagnostic, preparatory, practical and disciplinary.
