A survey of parents and students conducted from April 24 to 27, 2020, during the full transition of Russian schoolchildren to distance learning, showed that in conditions of self-isolation during the COVID-19 pandemic, there was a significant increase in the duration of educational and extracurricular activities using electronic devices; more than 70 % of students complained that during distance learning, homework began to take longer, which is explained by the low efficiency of classes, the vast majority (about 90 % of cases) of children did not carry out preventive measures to reduce fatigue and counteract harmful factors associated with visual analyzer stress and hypodynamia. The stressful situation in the conditions of self-isolation and distance learning affected the psychosomatic state of schoolchildren.

Anonymous voluntary questioning was carried out on teachers of educational organizations from 10 Russian regions. 7117 r espondents took part in the survey: kindergarten teachers of preschool educational organizations, teachers of three levels of school education. The research objective is to assess the teachers’ awareness about the basic terms and concepts associated with the functioning of the nervous system, age-related characteristics of cognitive activity and behavior of children and adolescents, problems of learning and social adaptation that may arise due to age-related features of the growing organism. The analysis of the obtained data did not reveal significant differences in the surveyed groups. There was no significant relation between teaching experience and the knowledge level. Predominance of correct answers was found among teachers of biology. The questions about the age characteristics of the cognitive activity of preschool children and adolescents were the most difficult for the respondents. The obtained results indicate the need for add itional educational programs for teachers, which will give them the opportunity to know recent concepts on the brain development and cognitive activity of a child. The data of this study could be used to develop the program and determine the content of the section "Brain development and the formation of the cognitive activity of a child" in the trai ning course "Pedagogical physiology"
