POCHULU, Marcel David. Meanings attributed to the solution of problems by using dynamic geometry software during the professional evolution of teachers. Relime [online]. 2010, vol.13, n.3, pp.307-336. ISSN 2007-6819.

The aim of this research is to establish the institutional and personal meanings attributed by a group of teachers when solving problems using dynamic geometric software during professional teacher training. The methodological characteristics of the research were qualitative and interpretative. Rather than using previously established hypotheses as a starting point, collected data was used and categories and conjectures were generated, the validity of which was tested during the research. The research shows that this particular professional teacher training, as well as the use of dynamic geometric software, helped to modify the conceptions of teachers in relation to mathematical objects and helped them to adjust them to the reference meanings.

Keywords : Institutional meaning; personal meaning; problem solving; professional teacher training; dynamic geometric software.
