The problem and the aim of the study. A teacher of a digital school, according to the requirements of the standard of professional activity, must possess such universal qualities related to information and communication technologies, formed communicative competence, the ability to work in a team. The formation of the relevant skills within the framework of university education is complicated by a number of problems of a different nature. The authors suggest organizing a practice of designing a system of specially selected tasks to improve the training of future teachers of a digital school. Research methods. The most important idea is the acquisition of new knowledge by creation and solving tasks. The solution of the system of educational, specially designed tasks supports the implementation of the provisions of the system-activity approach to learning. The pedagogical experiment involved 120 students of specialty 44.03.01 Pedagogical education (two training profiles, bachelor's degree level), Vyatka State University, Kirov, Russia Federation. Statistical verification of the obtained results was made using Fisher's criterion (angular transformation). Results. Students of the experimental group were involved in practical activities to design their own tasks on the example of studying the theory and methods of teaching Informatics (situational-motivational; support; border): self-determination of the plot, the development directions of intensification and extensification. Statistically significant differences were revealed between the experimental and control groups in terms of the level of professional training φcrit< φemp(1.64 < 2.558). In conclusion, the authors generalized the features of the organization of practical activity for the development of a system of own tasks for a digital school: the choice of the first task, the use of information sources of various nature, learning with and without a computer, group discussion of a result, resolving contradictions, "ignorance-knowledge-understanding-skill-proficiency", work in conditions of uncertainty, etc. © 2021 LLC Ecological Help.
