В настоящее время в связи с масштабным внедрением электронно-образовательного ресурса в учебный процесс особенно актуальным представляется поиск оптимальных характеристик предъявления информации на экранах с учётом специфики электронного носителя и возрастных физиологических особенностей зрительной системы пользователей.</p><p>Целью исследования явилась физиолого-гигиеническая оценка влияния шрифтового оформления электронных текстов, предъявляемых на ноутбуке, на психофизиологическое состояние детей 10–11-х классов.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Проведено психофизиологическое тестирование 43 школьников 10–11-х классов без патологии органов зрения на программно-аппаратном комплексе «НС-Психотест», включающее метод критической частоты слияния световых мельканий для оценки состояния центрального звена зрительного анализатора и исследование реакции на движущийся объект для определения степени сбалансированности нервных процессов. Изучалось влияние чтения алогичных текстов, набранных школьной гарнитурой, при размере шрифта 14, 12 и 10 пунктов, и объёме единовременного прочтения в 200, 400 и 600 знаков. Для предъявления информации использовался ноутбук Lenovo IdeaPad 720S-15.</p></sec><sec><title>Результаты</title><p>Результаты. Установлено, что у школьников 10–11-х классов отмечалось исходное утомление зрительного анализатора и нервной системы в целом. У мальчиков определялись более хорошие показатели КЧСМ, чем у девочек. Большинство старшеклассников имели сбалансированный вариант процессов торможения и возбуждения. Показано, что способы предъявления информации электронных учебных текстов могут влиять на психофизиологическое состояние школьников и нести риски здоровью обучающихся. Гигиенически рациональное оформление электронных учебных текстов способствует оптимизации психофункционального состояния организма учащихся.</p></sec><sec><title>Заключение</title><p>Заключение. Полученные результаты позволяют обосновать гигиенические требования к параметрам шрифтового оформления текстов электронных учебных изданий третьей ступени образования.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Currently, in connection with the large-scale introduction of the electronic educational resource in the educational process, it is especially relevant to search for optimal characteristics of presenting information on screens, taking into account the specifics of the electronic devices and age-related physiological features of the users’ visual system. </p><p>The aim of the study was a physiological hygienic assessment of the impact of the font design of e-texts, presented on a laptop, on the psychophysiological state of students in grades 10-11. </p></sec><sec><title>Material and methods</title><p>Material and methods. Psychophysiological testing of 43 schoolchildren in grades 10-11 without pathology of the vision organ was carried out on the NS-Psychotest complex, including the method of critical flicker fusion frequency to assess the state of the central part of the visual analyzer and the response to a moving object to determine the degree of the balance in nervous processes. The influence of reading illogical texts typed by a school headset was studied with a font size of 14, 12 and 10 points and a one-time reading of 200, 400 and 600 characters. Laptop Lenovo IdeaPad 720S-15 was used for the presentation of information. </p></sec><sec><title>Results</title><p>Results. High-grade schoolchildren were established to have the initial fatigue both of the visual analyzer and the nervous system as a whole. Boys showed better indices of the critical flicker fusion frequency than girls. Most schoolchildren had a balanced type of the inhibition and excitement processes. Methods of presenting information in electronic textbooks were shown to affect the psychophysiological state of high schoolchildren and may carry risks to their health. The hygienically rational design of electronic educational texts promotes the optimization of the psycho-functional state of the high schoolchildren’s body. </p></sec><sec><title>Conclusion</title><p>Conclusion. The obtained results allow substantiating hygienic requirements for the font design of e-learning publications at the third stage of education.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>гигиена учебной деятельности</kwd><kwd>здоровье старшеклассников</kwd><kwd>шрифтовое оформление</kwd><kwd>электронные учебные тексты</kwd><kwd>ноутбук</kwd><kwd>психофизиологическое тестирование</kwd><kwd>гигиенические требования</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hygiene of educational activities</kwd><kwd>high schoolchildren’s health</kwd><kwd>type design</kwd><kwd>e-learning texts</kwd><kwd>laptop</kwd><kwd>psychophysiological testing</kwd><kwd>hygiene requirements</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Богомолова Е.С., Кузмичев Ю.Г., Бадеева Т.В., Писарева А.Н., Ашина М.В., Ковальчук С.Н.
