Digital pedagogy has become not only an academic discipline but is also taking shape as a scientific direction today. Being at the stage of formation, digital pedagogy does not yet have a clear definition of the subject field, categorical apparatus and research methodology. The lack of substantiation of the scientific status of digital pedagogy complicates compliance with the requirements for scientific research. The authors of the current article consider the main approaches to define the elements of the scientific subject of digital pedagogy and concluded that they are currently not systematized and ordered. As a result of the study it is concluded that it is possible to limit the subject field of digital pedagogy based on its structure. The main elements are proposed to consider digital education, training and upbringing as mechanisms for the formation of three subsystems of human digital culture: information, praxeological and axiological, as well as the structural elements of each of them as a type of pedagogical activity: subject, object, means, environment, conditions, goal, result. The system built from the obtained elements will make it possible to formulate scientific problems for the research which results from the interaction of digital pedagogy and its components with each other and with the other branches of scientific knowledge, spheres of public life and social subjects.
