Modern education involves the use of information and communication technologies at different stages of the educational process. IT-technologies not only make it possible to automate the routine work of organizing the educational process, for example, scheduling, but also to improve the quality of education through the use of innovative intelligent digital technologies. A teacher who does not have specialized skills in programming and computer science sometimes loses the advantages of computer technologies due to a lack of understanding of their capabilities and place in their professional activity. The typology of IT technologies, in the context of their application in education, is designed to reveal the advantages of using computer applications and services, both in the activities of an individual teacher and for organizing the educational process as a whole. The relevance of the study is determined by the contradiction between the requirements of the state educational standard of teaching, indicating the maximum use of the capabilities of IT technologies in the educational process and the lack of pedagogical research on typologies and didactic properties of computer technologies and services. We will single out individual areas of pedagogical activity and, in accordance with them, classify various information and communication technologies and computer services. In our opinion, it is possible to define three types of application of IT-technologies in education: individual professional activity of a teacher, within the framework of which the teacher carries out the solution of their daily educational tasks; support of pedagogical activities, including technologies and services that ensure the organization of educational activities, both for the teacher and the institution as a whole; analysis of learning outcomes, designed to correct, predict and improve the quality of pedagogical influences.
