METHODOLOGICAL ASPECTS OF THE DEVELOPMENT OF MATHEMATICAL COMPETENCE AS A TOOL FOR DECISION-MAKING UNDER UNCERTAINTY

The purpose of the work is to characterize the methodological foundations of the formation and development of mathematical and information-digital competences of students of general secondary education institutions as a tool for forming their abstract thinking for decision-making in conditions of uncertainty. It is based on the concept of the development of abstract thinking as a process of mental activity of an individual as a higher form of thinking, which allows to operate with concepts, symbols, abstract ideas and representations, aimed at solving complex problems and making decisions in the conditions of underdefined or overdefined systems. The effectiveness of the proposed pedagogical technology is ensured by a child-centered orientation to the system of educational tasks that determine the formation of a system of abstract concepts, understanding their essence, and the development of applied skills in operating these categories in applied aspects. The main advantage of this pedagogical technology is ensuring that students learn the basic methods of solving educational problems, the application of mathematical competence for the development of information and digital competences in the conditions of digitization of education. Such a combination is a key factor in increasing the effectiveness of their educational activities in modern conditions of youth potential development. The proposed concept is an effective tool for the formation of students' mathematical and information-digital competences in the process of studying mathematics in the context of combined learning in indoor secondary education institutions, including in distance mode using synchronous and asynchronous communication tools.
