Lines of Practice: A Practice-Centered Theory of Interest Relationships

Based on a three-year-long ethnography of the hobby of model rocketry, I present a practice-centered theory of interest relationships—that is, the pattern of long-term, self-motivated engagement in open-ended practices that has been theorized under the concept of individual interests. In contrast to extant theories of individual interests, in which persistent engagement is pegged to a topic-specific relationship (e.g., a model rocketeer has an interest in the topic of rocketry, broadly conceived), I propose that persistence in a practice of interest is best understood in terms of what I call lines of practice. A line of practice is a distinctive, recurrent pattern of long-term engagement in a persons practice participation. Any line of practice entails a set of closely interrelated activities that are defined by two structural elements: preferences and conditions of practice. Preferences refer to the deep, long-term goals, values, and beliefs that a person develops in the practice, whereas conditions of practice refer to the constraints and affordances impinging on the persons practice (e.g., socioeconomic status and the norms of practice sites). A line of practice can thus be seen in the distinctive ways that a persons preferences are attuned, over the long haul, to specific conditions of practice, and how preferences cluster to form any single line. I show how persistent engagement can be understood in terms of the birth, death, and changes to a persons lines of practice and describe how this formulation broadens current theories of individual interests.

Knowing the Stability of Model Rockets: A Study of Learning in Interest-Based Practices

This article adds to sociocultural theories of learning by investigating knowing and learning in the hobby of model rocketry. Hobbies are paradigmatic of interest-based, long-term pursuits and studying the tailored practices the rocketeers craft for themselves sheds further light on the relationship between the nature of practices and the learning processes that emerge in their enactment. My window into this issue is the core problem of determining the stability of model rockets, across phases of design, construction, and flying. Using ethnographic and experimental data, I catalog the various individual and collective ways of knowing rocket stability and articulate the manners in which they operate to foster and sustain the highly tailored pursuits characteristic of interest-based practices.

Seeing in the Dark: Embodied Cognition in Amateur Astronomy Practice

We add to research on embodied cognition by investigating the observational practices of amateur astronomers. Specifically, we take an interactionist perspective and examine how the body is recruited, moment by moment, as a resource for producing and communicating meaning during field activity. The data corpus is a set of ethnographic video records and field notes on the routines of a community of astronomers, especially small-group interactions during planning, searching for, observing, and confirming sight of a celestial target. Within this space, our analysis highlights how different modalities of embodied action and reasoning (gestures, tool use, gaze, touch, and others) were deployed and coordinated throughout the process of observing a celestial object and how those emerged in the transactions among participants. Our findings rehearse many issues and topics in the contemporary literature (e.g., gesturing for measuring or representationally) but also reveal important, novel forms of embodied action and reasoning in science, technology, engineering, and mathematics practices (e.g., training the eyes in averted vision and inscribing a celestial scene onto one’s hand). More broadly, these findings further affirm the power of interactionist analyses of knowing and learning while also surfacing areas in which expanded theorizing is needed to account for the full set of cognitive phenomena we observed.
