    A cross-disciplinary examination of the user behaviours involved in seeking and evaluating data is surprisingly absent from the research data discussion. This review explores the data retrieval literature to identify commonalities in how users search for and evaluate observational research data. Two analytical frameworks rooted in information retrieval and science technology studies are used to identify key similarities in practices as a first step toward developing a model describing data retrieval

    Twitter in the collaborative classroom: micro-blogging for in-class collaborative discussions

    Get PDF
    While small group discussion during undergraduate classes is an important pedagogic strategy, there are two primary concerns for instructors how to monitor the conversation that goes on within groups, and how to ensure that ideas that emerge within the groups become part of the classroom discourse. In this paper, we describe a design-experiment conducted in two sections of the same undergraduate education class, exploring the use of Twitter, and a shared display of the Twitter-chat, to address these issues. We describe three iterations of the use of Twitter in the classes, and our reflections on how it influenced the teaching experience. Data from student surveys indicates that students had minimal experience using Twitter for academic activities prior to participation in this class and that they felt Twitter was a valuable tool to support their in-class learning activities. The teaching team found that the use of Twitter kept students on task and focused on the activity, but expressed some concern about the depth of engagement with ideas during the task

New York: Springer. doi:10.1007/978-1-4419-7710-6_9CSCL researchers are often interested in the processes that unfold between learners in online learning environments and the outcomes that stem from these interactions. However, studying collaborative learning processes is not an easy task. Researchers have to make quite a few methodological decisions such as how to study the collaborative process itself (e.g., develop a coding scheme or a questionnaire), on the appropriate unit of analysis (e.g., the individual or the group), and which statistical technique to use (e.g., descriptive statistics, analysis of variance, correlation analysis). Recently, several researchers have turned to multilevel analysis (MLA) to answer their research questions (e.g., Cress, 2008; De Wever, Van Keer, Schellens, & Valcke, 2007; Dewiyanti, Brand-Gruwel, Jochems, & Broers, 2007; Schellens, Van Keer, & Valcke, 2005; Strijbos, Martens, Jochems, & Broers, 2004; Stylianou-Georgiou, Papanastasiou, & Puntambekar, chapter #). However, CSCL studies that apply MLA analysis still remain relatively scarce. Instead, many CSCL researchers continue to use ‘traditional’ statistical techniques (e.g., analysis of variance, regression analysis), although these techniques may not be appropriate for what is being studied. An important aim of this chapter is therefore to explain why MLA is often necessary to correctly answer the questions CSCL researchers address. Furthermore, we wish to highlight the consequences of failing to use MLA when this is called for, using data from our own studies

    The Design Discourse of Professional Instructional Designers

    The design discourse of professional instructional designers (IDs) exposes the inner workings of instructional design because collaboration is integral to instructional design practice. Despite the importance of collaboration, there has been little examination of the collaboration in Instructional Design and Technology (IDT). To examine IDs’ collaboration, I examined the design discourse of IDs in design meetings with clients through a content analysis of their discourse. Analysis revealed areas of design expertise that frequented those discussions. I collected audio recordings of five discussions between one or more IDs and a client. Overall, six IDs and five clients participated in this study. A codebook of 16 codes provided ten codes of design discourse that appeared in the data and six subsequent codes that emerged as discourse management strategies. Among IDs, the most prominent type of design discourse was problem solving. When aggregating design discourse types, discussions surrounding problems, users, and tools were the three most frequent types and accounted for almost three-fourths of the design discourse of these designers in these discussions. Further analysis of the design discourse types revealed that precedent and user experience were the most complex areas of design discourse, suggesting that expressing precedent and user experience are advanced design skills. An analysis by gender revealed that male and female IDs focused on different areas of design discourse in practice. Female IDs focused on user experience and problem solving while male IDs concentrated on problem solving and tools. These findings have implications for how learners in IDT are trained, how design expertise is recognized, and how the design process is understood
