Ensaio da Ferramenta DIA Diagnóstico e Informação do aluno

Abstract

We´ve presented the results of our research for the conception, execution and evaluation of an informatized adaptive tool, known as DIA (in portuguese), that allows evaluate and give a feedback to the student under the perspective of formative evaluation. At the first stage, we used the PCN: Sciency of the Nature, Mathematics and its Technologies (BRASIL, 1998) and the Curriculum Matrices of Reference from the Instituto Nacional de Estudos e Pesquisas Educacionais -INEP, to the Sistem of Evaluation for Basic Education - SAEB (BRASIL, 2005) to build a scale in wich the objectives are in increasing order, according to the vertical development of the knowledge construction in Mathematics. We linked the proposed objectives to create a Data Bank (BI, in portuguese) that was used in our simulations. We´ve analized the results of our essay to evaluate the comunication between the data bank and the scale under the perspective of giving a diagnosis of the construction of the mathematics knowledge. In our essay, we simulated the functionning of the DIA tool through an adaptive informatized test based on the "Teoria de Resposta ao Item" (TRI). We were also interested on determing a profile of a Data Bank (BI) that is able to significantly dialogue with our scale through the TRI. The scale and the associated data bank should provide a constructive feedback that will help the stundents develop their metacognitives competencies.
