Safety of digital learning environment for the health of high school and university students in distance learning

Abstract

The development of technologies using the electromagnetic field (EMF) of the radio frequency range has become a leading trend related to the need for wireless data transmission. This made it possible for distance learning of schoolchildren and students in a dangerous epidemic situation. Accumulated data on the sensitivity of the human body to the action of EMF. The purpose of the work is to assess the conditions of teaching schoolchildren in computer science classrooms, as well as the impact of online learning on the health of high school students and university students. Based on the results of an online survey of schoolchildren and students according to the author’s questionnaire, a database was formed and an assessment of the conditions of distance learning was carried out. With the use of instrumental research, an assessment of the learning conditions in computer science classrooms was carried out. The materials were processed using the reliability criterion χ2 and the health risk assessment RR. Control data in computer science classrooms showed non-compliance of temperature, air humidity, air ionization, illumination, noise with regulatory requirements, except for EMF levels. With online learning, a high duration of stay of high school students and students in a digital environment has been established, including the learning process, homework, and leisure time on the Internet. In the structure of complaints related to studying online and doing homework, there were: visual impairment over the past year, headaches, back pain, irritability, eye fatigue, a feeling of dryness in the eyes. The time for sleep and physical activity decreased. Data have been obtained confirming the need to protect the health of students in a digital environment with the provision of safe conditions for visual work, limiting the time of use of digital devices, increasing the literacy of all users.

Prospects for Using Computer Accommodography to Predict Myopia Development in Young Adults

“…The identified high proportion of participants with signs of CVS among young people with preserved normal visual acuity and the absence of refractive errors may be a consequence of the digitalization of the educational process and the educational environment in a broad sense, which has taken place and is still ongoing [ 33 , 34 ]. This is another indication of the growing relevance of using the computer accommodation method allowing the early identification of changes in the main accommodation parameters in schoolchildren and university students, which, if left unattended, can lead to the development of myopic refraction in early years along with gaining education [ 27 , 35 ].…”
