Hygienic assessment of mental performance and emotional state of schoolchildren of different gender of 5-9 grades in lessons with different time duration of use a personal computer

Abstract

The article is devoted to the study of mental working capacity and emotional state of schoolchildren of 59 grades of different age and gender groups in the lessons with and without using a PC. There were observed 277 students of grades 5-9 (113 boys and 164 girls). Dynamic changes in the indices of mental working capacity and emotional state of children of different gender were analyzed at 94 lessons. It is shown that the use of computers in the educational process is a significant factor in the formation of fatigue in pupils of both gender, but the nature and level of reaction to it are not the same for boys and girls. The use of PCs in the classroom predetermines a variety of changes in the studied indicators, the orientation of which depends on the gender, age and time of its use in educational activities. The different duration of use of the PC affects, first of all, the quality of the proof-reading work - its accuracy. From the beginning to the end of the training in the main school, against the background of the growing intensification of training, the resistance to the training loads associated with the use of the PC in the lessons of girls is increasing, and in boys is decreasing. This indicates the need to take into account the various psychophysiological reactions of children of different gender, as well as the peculiarities of their perception of educational information in the development of methodological support for the learning process associated with the use of a personal computer.
