Learning theories epistemological foundations. In pass historic man, various explanations have been built to understand the phenomena of life and of the environment with which it interacts. As a result of this process, arise the so-called scientific theories, which are understood as: universal explanatory models, or semiotic (cognitive and symbolic) that represent a relationship of interdependence between two or more universal classes of facts, and constructions that have the power to retrodecir and predict any of the particular facts covered within that universal class. In particular, Abbagnano in 1987 summarizes the meaning of the term theory in three basic operations: theory involves the construction of a systematic unification scheme with high degree of comprehension, which results in its universality and its power of coverage regarding singular events. Theory implies the definition of a set of means of representation conceptual or symbolic, allowing transit between the explanatory scheme and unique facts. Theory involves the construction of a set of rules of inferences that allow the forecast of fact data. For Goetz, and LeCompte (1988), the theories are complexes created by the development of a set of interrelated systematically generalizations or propositions. Concepts, propositions and theories of science, are distinguished from non-scientific constructs, that satisfy the criteria marked by logical reasoning and are accepted by the scientific community.
These authors, raised in the social sciences often distinguish three levels of theory: great theory and its related theoretical models, Formal theory and scope intermediate and the Sustantiva.A theory below is a table overview related to these levels: box 2 levels of theory in the social sciences levels of theory definition 1. Strongly interrelated grand theory or paradigm theoretical systems of propositions and abstract concepts that describe, predict or explain, exhaustive and not probabilistically, broad categories of phenomena.
