Introduction. The methodological support of the educational process is considered from the point of view of the didactic construction of the information environment of education using technical pedagogical tools in the implementation of the pedagogical technology "learning through teaching". To increase the complexity of the teaching content, the effectiveness of combining the "learning through teaching" approach with information technologies is considered proven. The most developed idea of such a combination is the introduction of a "pedagogical agent (comrade)", which carries out communication with the subject area and is an analogue of an expert system. From the point of view of designing an information learning environment, we can talk about using technical tools or their analogs as boundary objects. Horizontal interaction of participants with each other in the implementation of the technology "learning through teaching" generates new boundary objects that can be considered as the basis of methodological support of the educational process. The combination of these two approaches is the theoretical basis of part of the research carried out at the Department of Algorithmic Mathematics of SPBSET "LETI". Results. The role and place of teaching materials in the implementation of the technology "learning through teaching" is presented. The changes in the understanding of the content of teaching are confirmed not only in direct active "teaching", but also in the preparation of teaching materials.
