Structural-hierarchical didactic model of e-learning

This article describes the original Structural-Hierarchical Didactic (SHD) model of e-learning. The model is based on a four-level methodological knowledge base. The first level includes a set of electronic educational encyclopedias in various fields of knowledge. The second level includes e-learning courses. The model supports the structuring of e-learning course on didactic components (vertical structuring) and levels of detail (horizontal structuring). The third level includes a set of syllabuses. The fourth level includes a set of a federal state educational standard of higher education (FSES HE). A distinctive feature of the SHD model is the division of educational objects into didactic components. This will allow, firstly, to automatically verify the didactic completeness of the electronic training course. Secondly, to include parts of one course in another without losing the didactic structure. Thirdly, to select a separate didactic layer from the electronic training course and, based on it, automatically generate specialized training materials: lecture notes, task collections, exam tests, etc. The basic operations of the SHD model are described, based on which analysis algorithms are proposed syllabuses and e-learning courses. In conclusion, a brief summary of the results and directions for further research is given.
