Problemas de estrutura aditiva: análise da resolução de alunos de 3ª série do ensino fundamental

Abstract

The present studyhad as general objective to analise the solution of problems with an addition structure from the pupils of the third year of the fundamental teaching, aiming to identify which kind of problems present difficulties to the pupils. The subjects of this research were pupils who belonged, on the whole, to two private school and one state school of Campo Grande/ MS. It was checked that the degree of the difficulty was bigger when the problems: 1) presented desconnection between the operation to be solved and the verbs or expressions in which the informations were; 2) didn’t search state (begginer, intermediate or final), but the relationship or transformations; 3) demanded inversion of the time sequence. It is believed that the teacher has a fundamental role in overcoming these kind of difficulties, when the one understands that the problems aim the building of concepts and that their solving must be proved by various situations.
