Abstract
This essay examines professional formation in education in education in a complex global and local context, marked by social, economic, political and cultural change, where traditional and transforming forces are in tension; among them, the empirical-analytical vision of modern science and the new postmodern theoretical-epistemological approaches. In this regard, it is proposed that professional training in education should be analyzed from paradigms more adjusted to the characteristics of social phenomena in our time, whose most significant feature is the increasing complexity. From the theoretical-epistemological and methodological contributions of the Theory of Social Systems by Niklas Luhmann and the Theory of Complexity by Edgar Morin, a model for the description, understanding and explanation of teacher professionalization is constructed, where it is understood as a system that contains in its structure and functions, the subsystems of the undergraduate, graduate and throughout the working life, which expresses, in turn, internal relations, between subsystems and with society (environment). It is derived from the model that of the form, relationships and development of teacher training levels it is possible to plan, control, manage and evaluate the professional performance of teachers and, consequently, the training system as a whole; For this reason, the proposed model serves as a reference to identify areas for improvement, as well as structural and functional problems of teacher professionalization, which cannot be detected or explained, based on an empirical-analytical approach to the phenomenon.
