The purpose of the research is to identify the influence of an educational text on the organisation of information activities of schoolchildren. Methods: content analysis, structural and semantic analysis of educational texts and the results of their interpretation. Research results: identification of features of the educational text as an information structure (the integrity of multi-layer content, reproducibility, presence of system connections with the thematic information field), description of the information activity of a complex of educational texts united by the function of updating the value attitude to knowledge, which can be represented in three main types: impersonal, authorised and personal. Each of these types is correlated with the level of perception of information by the student-reader, which can be a. detached and impersonal, b. in conscious collaboration with the author, c. to their own cognitive experience. As a result of the research, the basic information-significant structural components of educational texts are also identified: the title and the beginning correlated with the key meaning of the text, the means of axiological field and dialogisation.
