Abstract

This article offers a heuristic for conceptualizing the broad contours of electronic instruction sets as they have developed for and in online environments. The heuristic includes three interconnected models: self-contained, which leverages the features of fixed instructional content; embedded, which leverages the features of user-generated metadata; and open, which leverages the features of mutable instructional content. Although the models overlap to some extent, their distinctions help to illustrate the changing nature of online how-to discourse.
