abstract. This paper stems from the ReMath European project1 that focuses on the role of representations in dynamic digital artefacts (DDAs), and on the role of theoretical frameworks with respect to their use in educational contexts. Framed within the Theory of Semiotic Mediation, the paper presents some results concerning how the potentialities of the Aplusix DDA, and in particular of the feedback component, can be exploited by the teacher in relation with the notion of equivalence between algebraic expressions. Through a semiotic analysis of excerpts from a classroom discussion, evidence of the semiotic process triggered by the teacher’s interventions is provided.
