Resumo

Este estudo analisa a forma como os alunos do ensino Primário e Secundário resolvem problemas de estrutura multiplicativa (multiplicação, divisão-partitiva e divisão-medida). Foi utilizado um questionário com nove problemas em que se considerou o uso de números naturais e frações, e se analisou tanto o nível de sucesso como as estratégias implementadas em cada tipo de problema (por curso). Os resultados mostram um menor nível de acerto nos problemas com frações do que com números naturais, pois os alunos apresentaram dificuldades em identificar que a estrutura dos problemas era a mesma.  A utilização do algoritmo foi a estratégia mais utilizada; no entanto, outras estratégias surgiram dependendo do tipo de número implicado (números naturais ou frações).
