The Dark Matter of Lab Work: Illuminating the Negotiation of Disciplined Perception in Mechanics

This study examines the practical work of a pair of students and an instructor using probeware in a mechanics lab. The aim of the study is to describe and discuss a type of interactional sequence that we refer to as dark matter, the ordinary backdrop to the extraordinary sequences that are easily recognizable as clear-cut instances of learning. Although this work is downplayed in the research literature, describing it is critical to properly understanding lab work as an educational practice. With a focus on the negotiation of disciplined perception, we analyze a number of episodes wherein a pair of students and an instructor struggle with the construction and interpretation of a graph depicting a linear relationship between force and acceleration. We demonstrate an intimate interplay between how the students display their problems and understandings and how the instructor tries to make the subject matter content visible and thus learnable. The analyzed episodes are illuminating with regard to the analytical notion of disciplined perception as applied to graph interpretation; the cognitive and practical competencies involved in producing, recognizing, and understanding graphs in mechanics; and the interactive work by which these competencies are made into objects of learning and instruction.

Contrasting the use of tools for presentation and critique: Some cases from architectural education

This study investigates video recordings of design reviews in architectural education, focusing on how presentations and discussions of designs are contingent on the specific tools employed. In the analyzed recordings, three different setups are utilized: traditional posters, digital slide-show technologies, and combinations of the two. This range of different setups provides a set of contrasts that make visible the role of technologies in shaping the ways in which the reviews are conducted. The analysis is structured in three themes. First, we examine the sequential organization of digital presentations in relation to the spatial structure of poster-based presentations. Second, the different ways in which shared attention is established in digital, paper-based, and hybrid presentation practices are analyzed. Third, we address part-whole relations—how details in presented materials are put in relation to the overarching project or the presentation as a whole. Taken together, the analyses suggest that the detailed organization of the design review is transformed in subtle yet consequential ways through the introduction of digital slide-show technologies. These transformations are consequential not only locally, for the design review itself, but also for the instructive work that is accomplished through this practice. We conclude by discussing some implications for design, arguing that an increased awareness of how the practice is influenced by the different setups might be key for the proper adaptation of presentation technologies to particular purposes.

Vulgar competence, ethnomethodological indifference and curricular design

In the paper, we discuss the relation between ethnomethodologically inspired video analysis and curricular design. Often the relation between analysis and design is taken as a relation between descriptive and prescriptive accounts. Conceptualised in this way, ethnomethodology and curricular design is a world apart. With a focus on ethnomethodologys take on analytical and normative questions, however, some ethnomethodological insights might play an interesting role in investigation as well as development of computer based learning environments. The discussion is structured around four analytical commitments: become vulgarly competent; be indifferent to formal analytic methods, not member concerns; focus on actions and immanent pedagogies, not learning; and, do hybrid studies.

Seeing ethnographically: teaching ethnography as part of CSCW

While ethnography is an established part of CSCW research, teaching and learning ethnography presents unique and distinct challenges. This paper discusses a study of fieldwork and analysis amongst a group of students learning ethnography as part of a CSCW & design course. Studying the students’ practices we explore fieldwork as a learning experience, both learning about fieldsites as well as learning the practices of ethnography. During their fieldwork and analysis the students used a wiki to collaborate, sharing their field and analytic notes. From this we draw lessons for how ethnography can be taught as a collaborative analytic process and discuss extensions to the wiki to better support its use for collaborating around fieldnotes. In closing we reflect upon the role of learning ethnography as a practical hands on – rather than theoretical – pursuit.

Inquiries of the body Novice questions and the instructable observability of endodontic scenes

This study explores questions posed by students in response to live video broadcasts of dental treatments. The aim of the study is to show and discuss the reflexive relationship between the questions, what they were occasioned by and how they are responded to. Procedures and anatomical features, that for the seminar leader are unproblematically seen in endodontic terms, repeatedly present problems for the students. Visible but unrecognized shifts in the dentist’s work, for instance, provide occasions for questions of the form ‘What is he doing now?’. In the midst of an ongoing procedure, questions tend to be formulated as noticings that elicit instruction either about some detail of the dentist’s actions or about what a generic ‘one should’ or ‘should not do’, what ‘frequently’ happens and so on. It is shown, however, that the movement between specific here-and-now features on the one hand and more general issues on the other characterizes the entire scope of the relevant material, particularly because the seminar leaders’ answers tend to place even minute details within more general endodontic considerations.

Epistemic status and the recognizability of social actions

Although the production and recognition of social actions have been central concerns for conversation analysis (CA) from the outset, it has recently been argued that CA is yet to develop a systematic analysis of ‘action formation’. As a partial remedy to this situation, John Heritage introduces ‘epistemic status’, which he claims is an unavoidable component of the production and recognition of social action. His proposal addresses the question how is social action produced and recognized? by reference to another question how is relative knowledge recognized? Despite the importance placed on the latter question, it is not clear how it is to be answered in particular cases. We argue that the introduction of epistemic status builds on a reformulation of the action formation problem that unnecessarily de-emphasizes the importance of the sequential environment. Our re-analyses of key sequences cast doubts on the empirical grounding of the epistemic program, and question whether the fundamental role of epistemic status has been convincingly demonstrated.

Situated abstraction: From the particular to the general in second-order diagnostic work

The present study examines the work of a group of medical scientists as they identify interpretative ‘pitfalls’ – recurrent sources of error – in the use of a new radiographic technique, formulate suggestions on how these pitfalls can be avoided and communicate their findings in the form of a scientific publication. The analysis focuses on a session in which previously diagnosed cases are discussed, and demonstrates the ways in which a certain source of diagnostic error gradually emerges as a taken-for-granted in the interaction. An increased sense of recognition, recurrence and typicality is discernible in the treatment of the cases. Talk characterized by expansions and elaborations, displays of understanding in the form of reformulations, understanding checks, and so on, leave room for brief typifications and reifications of interpretative difficulties in characteristics of the imaging technique. Topical treatment of perception and interpretation, as well as embodied engagement, become decreasingly salient. It is argued that the abstracted formulations in the published text rely on the case-by-case working up of generality from particularity; from individualized accounts of why ‘I’ interpreted the image in a certain way to proffered generalizations achieved through articulated perceptions of a generalized ‘one’. If these proffers are ratified, a potential ground is established for the consensual formulation of a pitfall. The formulation of novel instructions is consequently made relevant, projecting a re-instructed diagnostic practice.

Space and discourse interleaved: intertextuality and interpretation in the education of architects

This study examines a sequence of instructional work taken from the practice of critique in architectural education. In analyzing the ways in which one instructor assesses and interprets how a group of students have worked with references to other architects and to well-known buildings, the study provides a respecification of notions of interpretation and intertextuality as practical features of design work: design anticipates professional interpretation, and is thus prospectively oriented towards the retrospective ascription of intertextual meanings. The sequence revolves around highly ideologically charged sites. The instructional work around the use of references to these sites highlights the modes of architectural reasoning implicated in the competent handling of ideology in relation to aesthetic expression. Finally, the space of the critique itself is shown as a rich site for the reproduction of architectural knowledge, in which multiple spatial and disciplinary contexts are embedded through representation, discourse, and embodied practice.
