Didactical engineering for the teaching of complex variable: visualizing the concepts related to the mathematical integration process

Abstract

This paper presents a theorical and a descriptive proposal for a Didactical Engineering – DE, in the context of teaching of a certain specific subject in Complex Analysis. Thus, emphasizing the two initial systematic phases, namely known as preliminary and a priori analysis, it tends to accentuate a design a conception, estructuration and description of two didactical situations for the teaching, affected by the assumptions of the Theory of Didactical Situatibons – TSD. Thus, to take as essential character of the ability of visualization, consolidating an apprentice action in searching of some properties related to the process of integration in the complex variable, the works also indicates certain aspects that should be explored with the GeoGebra software with the scope of enphasize some properties and significations of the symbol that go beyond the mathematical and logical sense.
