Arguing with objects and bodies: embodied reasoning and material entanglements in science learner interaction

Abstract

ABSTRACT How do people use objects and gestures to shape scientific argumentation? This paper engages the concept of “entanglement” as a heuristic for considering the potentials and constraints that gestures and materials create for interactants. Drawing on video recorded data from an academic-year-long linguistic ethnography of a high school science classroom in southern Arizona, USA, I examine the entanglement of discourse, bodies, and objects in one act sequence to reveal differences in the situated practices of high school students as opposed to professional scientists. The analysis reveals that objects and gestures allow scientific novices to engage in collaborative sense-making as they transform discourse and are transformed in discourse. At the same time, the flexibility and contingency of objects and gestures can be problematic for novices dealing with ambiguous understandings of natural phenomena, leading to interpretations that may or may not correspond to expert understandings. Reckoning with materiality in science argumentation must account for the limitations of objects and bodies as forms of evidence as well as their potential to afford forms of agency.
