This full paper concerns an exploratory study that investigates students' reasoning about torsion. Mechanical reasoning is critical to engineering applications and yet students still struggle to accurately predict, analyze, and model mechanical systems using formal symbolic notations (i.e., formalizations). To understand the nature of students'…

Drawing on interim findings from an ethnography of a cycle mechanics' workshop, this article demonstrates how the work of the mechanics rests on not only specific and contextualised craft expertise but also on distributed networks of both people and things, within which highly specialist instances of expertise or competence manifest alongside more…

This paper provides an account of the everyday workplace learning of cycle technicians. Derived from an ethnography of working cultures and practices at a bike shop in the North of England, this paper rests on a critical reading of Communities of Practice theory in order to explore the complex and heterogeneous learning of cycle technicians.…
