Ahead of this, it can be affirmed that the adequate knowledge to the individual development encloses aspects and consideraes of the two levels, that is, must be led in account, in this process, as much the level of the real development how much of the potential. 5.2 The IDEAS OF UBIRATAN D' AMBRSIO D' Ambrsio strong considers a resume marked with the contextualizao focusing the Etnomatemtica 3 for considering the Mathematics a cultural manifestation. the Mathematics of the school nothing more is of what only one of the many mathematical that if find for the diverse cultures. In the specific case of the Mathematical Education, the alternative most viable is to incorporate the programs the Etnomatemtica, even so rare either considered as integrant part of the pertaining to school mathematics. Observing the first references, as for example, in Plato or the proper Average Age, where it was constructed modern science, Etnomatemtica meets there. The incorporation of Etnomatemtica to practical the educational mathematics demands the release of some preconceptions on the proper Mathematics, as to understand what she is Mathematical, severity, demonstration, and what it is acceptable. Facts that generate a quarrel without which the Mathematical Education hardly will find the field adjusted to revitalize themselves.
This quarrel is of nature description-epistemolgica, unhappyly absent in almost the totality of the approaches to the Mathematical Education. The Mathematical Education being based on a pparently solid foundation that is the Mathematics as science, reflects this solidity. In some cases of elitist and pedante form, selecting the best minds, therefore the Mathematics as it disciplines pertaining to school is the responsible greater for frustrations, defections for the maintenance of an unjust and unacceptable social stratification. With the advances in the learning theories, the appearance of new applied technologies the Education, the recent progressos of the Mathematics and too much sciences provokes important and deep alterations in the education of Sciences and the Mathematics.
