Abstract
This study broadens the notion of Interpretative Knowledge (IK) into Semiotic Interpretative Knowledge (SIK) by considering the role of semiotic systems in mathematical thinking and learning. We analyse the relationship between SIK and feedback structured in four categories according to the semiotic functions involved. Based on quantitative and qualitative data we scrutinize the SIK and feedback deployed by prospective primary school teachers. Although connected with teachers’ mathematical knowledge, SIK is a specialized knowledge that requires specific training.
