Afectos y demostraciones geométricas en la formación inicial docente

Resum

Geometrical proving problems are studied during a first mathematics training course, analysing if and in which way affective dimension is manifested. A case of a student is presented observing her behaviour during two proof solving activities. The difficulties, proof schemes and language aspects were analyzed and associated with beliefs and attitudes towards geometrical students’ proof. A development profile and analysis of emotions in separated moments during the proof is recognized. It gives the opportunity to establish relations among affective domain and proof activities.
