Formação de professores de matemática: tecnologias e o Teorema de Tales

Abstract

This article presents some of the results obtained in a research conducted under the Program of Post-Graduate Studies in Mathematics Education of Pontifical Catholic University at Sao Paulo, whose objective was to verify what are the difficulties and possibilities of mathematics teachers using the software GeoGebra in activities involving the Theorem of Thales Likewise, it was intended also to investigate what possible role technology in the teaching work of these same teachers. Four teachers of public schools of state of São Paulo, working in elementary education from the 6th grade, took part in this investigation. The analysis allows to position the interactions produced by the subjects in levels of fluency with respect to the use of the technologies involved, besides to provide the identification of the doubts of teachers in relation to the mathematical content in question.
