In recent years, there has been a sharp drop in the motivation of young people to study using traditional paper and electronic textbooks.  In this regard, modeling of the structure and content of educational tools adequate to the cognitive characteristics of modern students is of interest.

The work is devoted to the substantiation of an approach to the creation of innovative textbooks based on the platform of structural-mental schemes and the question-problem format of the content of the discipline (on the example of the topic of school mathematics «Equations», grades 6-11). A mental approach is used, which has determined a number of positions in the design of educational teaching tools along the content line of the school algebra course «Equations»: the question-problem format of the structural composition of educational content; the principle of «vertical lever» in the selection of educational content; the principle of a «transparent chest» for visualizing the learning process and self-control of knowledge.

The expert survey showed high ratings of the didactic qualities of the created complex of teaching tools on the topic «equations» The developed innovative teaching tools, using the example of the topic of school mathematics «equations», showed the possibility and necessity of creating innovative electronic textbooks for self-study and self-control of students. The proposed approach can be applied to other substantive lines of subject disciplines at school and university.
