When educational standards are revised and attention to the quality of textbooks is increased, the analysis of diachronic changes in the structure and content of Russian language textbooks becomes relevant to determine the main factors affecting the educational process. The aim of this study is to examine the linguistic specificity of text formants in Russian language textbooks and analyze the trends of their changes over time. The materials of the study include Russian language textbooks published in the Soviet Union (1935-1974) and in Russia (2012-2015). The research methods are based on the comparative analysis of linguistic parameters of formants ‘Exercises’ - ‘Tasks’ - ‘Theory’ and statistical tests to identify differences between these categories. The research showed statistically significant differences in most linguistic parameters, which confirm the thesis about the educational text heterogeneity. The most important differences among the formant categories were observed in the following parameters: Flesh-Kincaid Score, Global Noun Overlap, Type-Token Ratio, Singletons, Past Tense Verbs, Mean Sentence Length, Mean Word Length, Global Argument Overlap, and the Number of Nouns in the Genitive Case. Modern Russian language textbooks have lower lexical density and fewer nouns per 1000 tokens, higher local noun repetition, more frequent future tense verb forms, and higher global text coherence. These patterns reflect diachronic changes in the texts from Russian language textbooks. Future research should expand the range of the analyzed Russian language textbooks, particularly by including texts from textbooks for senior and elementary school, as well as a more detailed examination of the dynamics of linguistic parameter changes in Russian language textbooks during the Soviet period.</p></abstract><trans-abstract xml:lang="ru"><p>Актуальность исследования обусловлена необходимостью более полного понимания учебного текста как жанрового комплекса, выполняющего полифункциональную роль в образовательном процессе. В условиях пересмотра образовательных стандартов и повышенного внимания к качеству учебников анализ диахронических изменений в структуре и содержании учебников русского языка становится актуальным для определения основных факторов, влияющих на образовательный процесс. Целью данного исследования является изучение лингвистической специфики формантов текстов учебников русского языка и анализ тенденций их изменения со временем. Материалы исследования включают учебники русского языка, опубликованные в Советском Союзе (1935-1974) и в современной России (2012-2015). Методы исследования основаны на сравнительном анализе лингвистических параметров формантов: упражнения - задания - теория, с применением статистических тестов для выявления различий между этими категориями. Результаты исследования показали наличие статистически значимых различий по большинству лингвистических параметров, что подтверждает тезис о неоднородности учебных текстов. Наиболее выраженные различия между категориями формант наблюдались по следующим параметрам: индекс Флеша - Кинкейда ( p &lt; 0,01), глобальное совпадение существительных ( p &lt; 0,01), соотношение типов и слов ( p &lt; 0,01), синглетоны ( p &lt; 0,01), глаголы прошедшего времени ( p &lt; 0,01), средняя длина предложения ( p &lt; 0,01), средняя длина слова ( p &lt; 0,01), глобальное совпадение аргументов ( p &lt; 0,01) и количество существительных в родительном падеже ( p &lt; 0,01). Современные учебники русского языка характеризуются меньшей лексической плотностью ( p &lt; 0,05) и меньшим количеством существительных на 1000 лексем ( p &lt; 0,05), большей локальной повторяемостью существительных ( p &lt; 0,05), более частым использованием глаголов будущего времени ( p &lt; 0,01) и большей глобальной связностью текста ( p &lt; 0,05). Эти закономерности отражают диахронические изменения в тексте учебников русского языка. Перспектива исследования видится в расширении круга анализируемых учебников русского языка, в частности, за счет включения текстов как для старшей, так и для начальной школы, а также в более детальном изучении динамики изменения лингвистических параметров учебников русского языка в советский период.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Russian language textbook</kwd><kwd>formant</kwd><kwd>genre complex</kwd><kwd>linguistic parameters</kwd><kwd>textbook structure</kwd><kwd>RuLingva</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>учебник по русскому языку</kwd><kwd>формант</kwd><kwd>жанровый комплекс</kwd><kwd>лингвистические параметры</kwd><kwd>структура учебника</kwd><kwd>RuLingva</kwd></kwd-group><funding-group><funding-statement xml:lang="en">This article has been supported by the Kazan Federal University Strategic Academic Leadership Program (PRIORITY-2030).
