Professionalization of professors: knowledge, wisdom and necessary abilities to teaching

We have as a goal to analyze different classifications and types of knowledge, wisdom and necessary abilities to the exercise of teaching. The eleven raised studies represent a modest part of the research made in the two last decades. Still thus, it was possible, get to four conclusions about them; first, that there is a variety of authors who have intended to command the plurality, composition and heterogeneity of professional knowledge of the professors; secondly, that the classifications and types of abilities elaborated, as a result of these studies, are as plural, diverse and heterogeneous as their object of analysis, what makes impossible a comparison between them; third, the proliferation of classifications and types in place of improving the understanding of knowledge studied by them, it increased their complexity and made them less intelligible; fourth, in spite of being plural, diverse and heterogeneous, the variety of approaches had the same meaning or almost the same for the 11 authors studied.
