Electronic application "Constructor of informatics lessons plans" as a modern means of forming the professional and methodological competencies of a future informatics teacher

The article presents the results of the analysis of publications in some scholarly journals on the theory and methodology of teaching informatics — competencies that a modern informatics teacher should have are identified: the ability to expand and fill with new content the goal-setting system, the process of implementing interdisciplinary project activities of students; readiness to form knowledge and skills in communicating with students and organizing various types of student cooperation at different stages of an informatics lesson; the ability to predict learning outcomes and assess the need for appropriate modern didactic materials and means of teaching students informatics in the context of the digital transformation of society. For their formation, a necessary condition is the ability of students to design lesson plans. For this purpose, an electronic application was developed. The authors' vision of the presentation of sections of the electronic learning tool is given (sections "Introduction to app", "Formation of individual elements of the lesson plan", "Designing the content of the lesson plan", "My notes"). The system of tasks and exercises for step-by-step teaching of students to construct informatics lesson plans is described. The task is considered as a comprehensive development of a complete informatics lesson plan or its fragment based on the didactic materials presented in the electronic learning tool. Each exercise is an indication of a certain set of actions that must be performed in order to implement a portion of the overall plan. Examples of recommendations of how to assess student works are also provided.
