Hygienic substantiation of the mode of intense mental work of middle-schoolchildren at the performance of educational tasks

Abstract

The article is devoted to the analysis and generalization of the results of research on the study of mental performance and fatigue of students. The aim is to assess the mental working ability of middle-aged schoolchildren when actively solving mathematical problems and problems in order to develop a hygienically rational mode of work in the conditions of mental activity. The core samples of the letter table of V. Ya. Anfimov were selected as the methodological tools. According to the results of the study, the values of the daily adaptability index indicated a pronounced fatigue of the children during the school day. The performance of educational tasks in mathematics, associated with the active solution of examples and problems, causes a significant strain on the functions of the organ and leads to rapid mental fatigue of students. The conducted research showed that 20–30 min. intensive intellectual activity followed by 10–15 minutes active recreation in the fresh air are the optimal periods of work for schoolchildren. Sedentary rest in the corridors of the school does not provide a sufficient recovery of mental performance of students. Thus, the educational process should be structured in such a way as to prevent the occurrence of overwork, which creates the prerequisites for the development of acute and chronic health disorders, the development of nervous, psychosomatic and other diseases.
