Um estudo a respeito do professor de matemática e a implementação de uma seqüência didática para a abordagem da estatística no ensino médio

Abstract

The National Curricular Parameters (1997) had included contents of statistics in Basic and Average education as part of the program of Mathematics, that was very important so that it had changes in the education of the Statistics, the fact took the publishing companies to a bigger concern about the education of this topic, thus, they had passed to include the Statistics of a form in such a way elaborated in its manuals more and the mathematics teachers comes reflecting on its practical. But the researches show that the universities nowadays come working of a very limited form in the education of the statistics, making that they leave classrooms as professionals with low preparation about this topic and how to work, therefore the majority of the mathematics professors had crystallized in their practical knows little on statistics and the proposals of the PCN for the education of this topic. The proposal of this work is applied in an inquiry that will involve professor and pupils of average education. Verify if this educator would teach its pupils to solve a list with elaborated problems to understand average; medium; mode; standard deviation; quartiles and graphs as it would proceed after some adjustments considered about the Technician, Mobilized and Available. After the preparation of the professor and the results of this preparation have been implemented in its classroom, as the pupils would answer the list proposal to the test, and in which level of conceitualization considered for Robert (1998), these pupils had surveyed
