Processos usados na resolução de tarefas estatísticas

Abstract

This article focuses the processes that Alberto – a 7th grade student – uses to solve statistical tasks. It is analysed the way Alberto solves a set of situations proposed in three interviews – the first one conducted just before the study of Statistics, the second one immediately after this study and the third one three months lather – and identified how the strategies that he uses changed after the teaching experience. Data analysis showed that some of the strategies used by Alberto correspond to processes that continue to be used after the study of Statistics. It was also identified a tendency to associate several statistics concepts with the use of formulae and the difficulty to analyse, interpret, and communicate information.
