Tracking evaluative judgement over time
An evaluative event, so named because of the centrality of the operation of evaluative
judgement and transmission of criteria in pedagogic discourse, begins with the announcement
of an object of acquisition and ends at a point in the discourse when
attention to the particular object has reached some closure, and/or with the announcement
of a new object of acquisition. Of course, this occurs over time. Hence,
following Davis (2005), an evaluative event theoretically moves through four
moments of pedagogic judgement recognisable over a temporal segment of classroom
interaction: existence (E), reflection (R), necessity (N), and contingent notion (C). A
contingent notion has resonance with Chevallard's (1992) notion of ‘institutional
relation’ to a concept that is realised in a particular activity, i.e. context and set of
practices.
