Introduction. The relevance of the study is due to the state of modern learning theory, which does not define the ways of implementing individualization and metasubjectivity in educational activities. The purpose of the article is to reveal the methodological foundations for building a modular learning technology with a double degree of differentiation for the formation of universal learning activities as meta-subject results. Methodology and methods. The methodological basis of the research is the ideas and principles of technological, systemic, synergistic, individual, cognitive and metasubject approaches. They make it possible to justify and ensure the individualization and achievement of meta-subject results of the educational activities of schoolchildren. 2075 students and 564 teachers of secondary schools, 401 university students of pedagogical areas of training, 103 teachers of higher education have participated in a longitudinal experimental study to confirm theoretical conclusions since 1990. Results. The main results of the study consist in revealing the essence of modular education with a double degree of differentiation as a complex educational technology for individualizing the educational activities of schoolchildren and forming meta-subject results in it. The structure of the training module of the new format is also presented. The empirical facts and trends were recorded by the study, indicating a decrease in schoolchildren's anxiety in learning by the factors "fear of a situation of testing knowledge" (‒ 55%), "fear of self-expression" (‒ 31%)"; staying in a “normal” emotional state (81%) with an even, calm emotional background of the lesson (68%) and an increased ( joyful) state (23%), provided that the training session is organized in a technology mode; about the positive dynamics of teachers' possession of methodological skills when mastering technology as a system (application of methods of pedagogical research – 52%; the ability to independently develop an independent questionnaire, a test, a measuring tool – 48%; the ability to generalize the results of experimental work – 30%). Also, more than 500 models of innovative lessons for achieving metasubject results, 134 modules taking into account the cognitive style, and many level tasks have been developed. Scientific novelty. The scientific novelty of the research is determined by the substantiation and development of a didactic system that simultaneously determines the solution of two problems: the achievement of meta-subject results by students in a comfortable individualized educational environment. The results of the research develop the didactic theory of educational technologies, meta-objectivity and individualization. Practical significance. The significance of the results lies in the development of a technology which is useful for modernizing the learning process in the context of the development of individuality and the achievement of metasubject results in educational activities in general educational organizations, higher education, and further vocational institutions.
