Computer-Supported Collaborative Blended Learning (CSCBL) scripts are complex learning situations in which formal and informal activities conducted at different spatial locations are coordinated and integrated into one unique learning setting through the use of technology. We define a conceptual model identifying four factors to be considered when…

In vision-based augmented-reality (AR) environments, users view the physical world through a video feed or device that "augments" the display with a graphical or informational overlay. Our goal in this manuscript is to ask "how" and "why" these new technologies create opportunities for learning. We suggest that AR is…

Some recent proposals on CSCL scripts have suggested that one key factor for their effectiveness is the ability of the teacher to adapt the scripts to the students and to the specific teaching and learning situations. In this context, this paper presents a multiple-case study dealing with the relationship between the assistance given by the…

Our research aims to identify children's communicative strategies when faced with the task of solving a geometric puzzle in CSCL contexts. We investigated how to identify and trace "distributed cognition" in problem-solving interactions based on discursive cohesion to objects, participants, and prior discursive content, and geometric and…

This paper aims to better understand the development of students' metacognitive learning processes when participating actively in a CSCL system called KnowCat. To this end, a longitudinal case study was designed, in which 18 university students took part in a 12-month (two semesters) learning project. The students followed an instructional…

Prior research has highlighted the value of using wikis to support learning. This paper makes the case that the wiki has several properties that are particularly amenable for constructing applications that support the "collaborative" part of a variety and range of different time/different place student collaborations. In support of the argument,…

Genre analysis, the investigation of typified communicative actions arising in recurrent situations, has been developed to study information use and interchange online, in businesses and in other organizations. As such, it holds out promise for the investigation of similarly typified communicative actions and situations in CSCL contexts. This…

Very often, when using a chat tool where more than one participant is talking simultaneously, it is difficult to follow the conversation, read all the different messages and work out who is talking to whom about what. This problem has been dubbed "Chat Confusion." This article investigates this problem in debate sessions in an online university…

In order to collaborate effectively in group discourse on a topic like mathematical patterns, group participants must organize their activities in ways that share the significance of their utterances, inscriptions, and behaviors. Here, we report the results of a ethnomethodological case study of collaborative math problem-solving activities…

The use and effects of a CSCL-tool are not always predictable from the properties of the tool alone, but depend on how that tool is appropriated. This paper presents the findings from a case study about the appropriation of a graphical shared workspace. When students are presented with a new tool they may encounter competing constraints and…

Trends in higher education have contributed to the need for more coordination and collaboration among different constituencies involved in instructional design and delivery. As researchers and educational technologists working in a large public research university, our research focuses on understanding the interactions among various stakeholder…

How to teach flexible thinking and learning skills, particularly creativity and the skill of "learning to learn," is a key concern for CSCL in the context of the emerging Networked Society. The currently dominant paradigms for supporting pedagogical design within CSCL, including socio-cultural theory, are limited in the support that they can offer…

This paper presents results of a case study conducted in secondary mathematics classrooms using a new generation of networked classroom technology (Participatory Simulations). Potential for drawing on youths' cultural practices in networked learning environments is explored in terms of opportunities for traditionally underserved students to…

This qualitative case study illustrates barriers to informal argumentation and reasoned debate, i.e., "critical discourse," in online forums. The case is the computer conference of a 15-week, graduate-level humanities course offered entirely at a distance. Twelve students, all with families and careers, were enrolled in the course. We read all…

This article presents findings from a comparative case study of the learning experiences of two graduate students in an online action research course. The key roles played by reflection and co-reflection, an emerging concept, are identified through the use of narrative analysis. Co-reflection is a collaborative critical thinking process mediated…
