Faceted educational and information systems in the system of advanced training for teachers of natural science disciplines

The research problem and the rationale for its relevance. Modern education involves the integration of innovative didactic techniques and new information and communication technologies, one of the results of which are automated educational and information systems. The research problem is to substantiate the use of faceted educational and information systems that solve the problem of constructing multi-level tasks, based on faceted classification and cloud services. The goal of the research is to describe and study the process of creating faceted educational and information complexes, determining the effectiveness of their application and use in the system of retraining and advanced training of teachers. Methodology (materials and methods). In the course of the research, the methods of analysis of pedagogical and methodological literature on computer didactics, generalization of the pedagogical experience of designing educational complexes. Results. The article proposes a model for designing a faceted educational information complex. Variants of using the facet classification in the constructive activity of a teacher are indicated and reasoned. The place of automated educational and information systems in the professional training of teachers, in the system of improving their qualifications has been determined. An example of constructing a set of facet formulas and generating the corresponding problems is given. The didactic properties of cloud technologies and services are revealed, which perform the function of automating the construction, storage and transformation of faceted formulas in the faceted complex. A survey of students of advanced training courses was carried out, which revealed their attitude to the technology of facet design of tasks and the possibility of using facet complexes in their own pedagogical practice. During the experiment, teachers designed sets of faceted formulas in mathematics and computer science, developed faceted educational information complexes that can be used in the educational process. It is concluded that the inclusion of faceted complexes in the system of advanced training and retraining of teachers allows developing the creative potential of the teacher, implementing the principles of differentiation and individualization of teaching through the automated generation of multilevel tasks.
