Resumo(s)
This work aims the understanding of how the conceptual progression on plants reproduction presents itself to the primary school students. Was made a exploratory study (Arnal et al., 2001) to select three students for the instrumental case study (Stake, 2000) and performed in-depth interviews (Arksey & Knight, 1999). From the conceptions collected was builted an Progression Hypothesis presented according to nineteen categories and three levels of conceptualisation. According to this progression hypothesis we were able to identify the obstacle in the learning process of the concept plants reproduction.
