| Resumo: | [EN] THE EXTENSION OF VAN HIELE'S MODEL TO THE CONCEPT OF AREA The extension of Van Hiele's model outside the geometrical sphere and of the basic educational levels has been an opened question up to the moment when Professor LLorens read his thesis in 1994 at the Polytechnic University of Valencia. Here the concept of local proximity was applied to one of its most visual and geometrical manifestations: the tangent line to a specific point in a curve. Some other possibilities were displayed there, together with a specific methodology to be used, in a similar or more interesting way than this present thesis. Even though a lot of works related to this topic were published and at least five doctoral theses were written, as a progressive extension of the previous one, there are some questions which are still considered to represent a high level of interest. One of these questions, maybe the most relevant for the A level teaching and its mathematical foundations, is represented by the title of this thesis, both for its direct interest and the concept of whole. We have extended Van Hiele's model to the concept of area by formulating the corresponding descriptors and proposing methodological actions which are in favour of the progress of the reasoning process. We have used the decomposition into areas of a mixtilinear trapezium, with visual and numerical components, as a mechanism to approach the first stage of the concept. The numerical component, related to the previous extensions, represents a breakdown. Using as a tool a Socratic interview, in the daily process of feedback of these interviews, we have reached a formulation of the descriptors which later on has been confirmed by means of a standard guideline answered in at least twenty interviews. Apart from that we have developed a written test, which lacks the precision of an interview but with other advantages represented by the use of accurate statistic tools. This test enabled us to verify the existence of two levels of reasoning, previously described, and the possibility to detect them. Hence this work has been able to prove that Van Hiele's model is able to describe the process of reasoning in other pillar of the mathematical analysis. Also it highlights that some educational routines do not favour the right learning of some concepts. There is a high number of students who, despite their academic results, have not reached the third stage. The emphasis in mechanical or algebraic topics decreases the possibility of realizing other type of work which may be more appropriate for a better comprehension. That is to say that, the skill in algebraic tools is not linked to a high level of reasoning. As a consequence, the use of visuals is reopened to debate in order to favour the create learning situations which lead to the increase in the level of reasoning. |
