FERREIRA, Emilia Barra; SOARES, Adriana Benevides  e  LIMA, Josefino Cabral. The recovery of the demonstrations: a contribution of the computer science to the teachers of mathematics formation. Psicol. esc. educ. [online]. 2008, vol.12, n.2, pp. 381-389. ISSN 1413-8557.

The objective of this work was to investigate the dynamic geometry environment contribution in a process of Mathematics' teachers continuous formation, in order to motivate them to use demonstrations. In that direction, a didactic engineering was developed, in a dynamic geometry environment, seeking the participants' formation in both conceptual and didactic aspects. Eight in service Mathematics teachers participated in the activities and the instruments used for data collection were: survey questionnaires, the participants' production in the form of written material, registration of teachers' manifestations during the discussion of texts, and the didactic sequence elaborated by the participants to be applied to their students. The results revealed that the work in that environment, constitutes an efficient alternative in the process of teacher preparation in order to motivate them to use demonstrations.
