摘要：This essay discuss about the science and investigation construction. For it, the system concepts and system’s environment are approached, denoting that the category science is expressed through models and in that sense one doesn’t correspond one by one with those of the system’s environment. The science is then abstract knowledge expressed as theory. In this sense it’s related directly with the pedagogy as long as the construction-reconstruction of knowledge is necessary to make it on the base of the empiric test of the theories keeping in mind to the fellow that learns , and therefore, developing their capacities to use them professionally.
