A Mathematical Congress: A Window To Affect In Problem Solving

In this paper we focus at an on-going project taking place at a secondary school open to the whole community, the mathematical congress, that aims to develop students' interest about mathematics and to improve their problem solving and communication skills. The results suggest that most students, and not only the high achieving ones, are able to follow a line of reasoning, develop self-confidence in their mathematical communication capacity and choose their participation in the mathematical congress as one of the most interesting and important things in which they have been involved at school.
