Designing for communication at work: A case for technology-enhanced boundary objects

In this article we conceptualise the challenges of communication between a mortgage company and its customers in terms of crossing boundaries between communities. Through an ethnographic study we first address the question: what are the challenges of communication between sales agents and customers of a mortgage company around mathematical artefacts? Insight into these challenges formed the basis for an intervention in which we designed technology-enhanced boundary objects (TEBOs) that were reconfigurations of problematic symbolic artefacts. Secondly, we ask what the sales agents learned from the intervention. The data suggest that the intervention with the TEBOs helped employees to develop a better understanding of the mathematics behind the mortgages they sold, and to improve communication with their customers.     

Learning from Texts and Visual Aids: a Developmental Perspective

The aims of this research were to investigate the ways in which students in primary and secondary schools process texts and accompanying visual aids and to ascertain any developmental patterns. Think-aloud protocols were gathered from 119 Grade 5, Grade 7 and Grade 9 students while they read and studied grade-appropriate History and Science materials which contained both text and visual aids (tables, diagrams). Analyses of the think-aloud protocols yielded over 50 different processes, subsumed under 10 major categories. While the History results showed no reliable grade differences in the 10 think-aloud categories, the Science results showed developmental differences. Older students demonstrated a more diverse array of strategies, and explicit linking of text and visual aid information was not as evident in the younger students. ANOVAs following cluster analyses showed weak relationships between cluster membership and outcomes. Implications for instruction are discussed.     

Generic qualitative dissertations in counselor education: A content analysis

We conducted a content analysis of generic qualitative counseling dissertations (GQR; N = 70), examining their methodological justifications, coherence, and trustworthiness. Dissertations authors often presented vague methodological justifications. Findings have implications for constructing methodological justifications, integrating relevant literature, and awareness of how GQR compares to other qualitative methodologies.
