Abstract
In this chapter, I investigate how children understand concepts and the meaning of symbolic representations when working with conceptual models. The particular focus of this study is the nature of children’s conversation when collaborating to solve tasks embodied in what we call an intermediate abstraction. The analysis is based on theoretical considerations developed by Greeno and his colleagues (Greeno, 1989; Greeno, Engle, Kerr, & Moore, 1993) and on a line of research carried out by Resnick and Schwarz (Schwarz, Kohn, & Resnick, 1993; Schwarz & Nathan, 1993; Schwarz, Nathan, & Resnick, 1996; Schwarz, in press) with several computerized systems. My approach focuses theoretical attention on the nature of conversational turn-taking between children working with an intermediate abstraction of mathematical operators. This study shows that conversational processes of acceptance stemmed from collaborative learning, and that those processes enabled the construction of shared meaning resulting in the development of the concept of a mathematical operator. Three such processes were found. The first one is a process of creation of a shared meaning through reference to objects of the system. This process is initiated by one participant describing a property of the intermediate abstraction. The second participant then accepts the meaning uttered by the first participant and refines it. The second one is a process of convergence of a different nature that is initiated by an impasse within one particular representation and is characterized by a change of representation.
