Abstract

In this study, we investigated how students manage their lack of/insufficient understanding of the content of a mathematical task with the aim of reaching shared understanding and epistemic balance in peer interaction. The data consist of recordings collected during a mathematics project in a Finnish lower secondary school. The findings, drawing on conversation analysis, showed two markedly different sequence trajectories: how interaction between a K+ and a K− student proceeded relatively smoothly when these positions were accepted by both participants, and consequently the K+ led epistemic work by designing turns that resembled teachers’ practices; and how the K+/k− interaction became extended when a K− challenged the K+’s knowledge claims, and furthermore, how a K− steered the epistemic work using polar and wh-interrogatives. The findings contribute to a better understanding of the ways the management of epistemic imbalance can progress during peer group work.
