Development of general professional competencies of teacher training students for optimizing educational institution strategies through analysis and visualization of experimental data as part of a short course

The article considers certain aspects of teaching students pedagogical directions of preparation for analysis and visualization of experimental data. The tasks of the laboratory work of the course "Technologies of Digital Education" developed by the author are presented, allowing students to learn how to look for patterns in the data and draw the right conclusions on a task that is close to real, clearly selected in order to work out basic analytics techniques in spreadsheets, formulating a hypothesis for further mathematical justification of the identified trends. The structure of the presentation of educational material is proposed, which, on the one hand, allows, without loss of quality, to integrate the study of a rather extensive topic into the framework of a small course, on the other hand, to give the future specialist an effective tool for building an educational strategy.
