Computer-mediated knowledge communication

New communication technologies enable an array of new working and learning scenarios in which knowledge is being communicated. This article deals with the question to what extent these technologies can impede or facilitate knowledge communication. First, the various computer-based communication technologies will be classified. Second, effects of the medium on knowledge communication will be discussed based on results of studies of the current special priority program "Net-based Knowledge Communication in Groups". Third and last, computer-based possibilities to facilitate computer-mediated knowledge communication will be reviewNeue Kommunikationstechnologien ermöglichen eine Reihe neuer Arbeits- und Lernszenarien in denen Wissen kommuniziert wird. Dieser Beitrag beschäftigt sich damit, inwiefern diese Technologien Wissenskommunikation einschränken oder fördern können. Dazu werden in einem ersten Schritt die verschiedenen computerbasierten Kommunikationstechnologien untergliedert. In einem zweiten Schritt werden Wirkungen des Mediums auf die Wissenskommunikation diskutiert. Dazu werden u. a. die Ergebnisse von Studien des aktuellen Forschungsschwerpunkts "Netzbasierte Wissenskommunikation in Gruppen" berichtet. In einem dritten und letzten Schritt werden computerbasierte Möglichkeiten zusammengefasst, computervermittelte Wissenskommunikation zu förd

Practical Strategies for Integrating a Conversation Analyst in an Iterative Design Process

We present a case study of an iterative design process that includes a conversation analyst. We discuss potential benefits of conversation analysis for design, and we describe our strategies for integrating the conversation analyst in the design process. Since the analyst on our team had no previous exposure to design or engineering, and none of the other members of our team had any experience with conversation analysis, we needed to build a foundation for our interaction. One of our key strategies was to pair the conversation analyst with a designer in a highly interactive collaboration. Our tactics have been effective on our project, leading to valuable results that we believe we could not have obtained using another method. We hope that this paper can serve as a practical guide to those interested in establishing a productive and efficient working relationship between a conversation analyst and the other members of a design team.Comment: 11 page

Falling through the (cultural) gaps?

In this paper we report findings of a study of online participation by culturally diverse participants in a distance adult education course offered in Canada, and examine two of the study’s early findings. First, we explore both the historical and cultural origins of “cyberculture values” as manifested in our findings, using the notions of explicit and implicit enforcement of those values. Second, we examine the notion of “cultural gaps” between participants in the course and the potential consequences for online communication successes and difficulties. We also discuss theoretical perspectives from Sociolinguistics, Applied Linguistics, Genre and Literacy Theory and Aboriginal Education that may shed further light on “cultural gaps” in online communications. Finally, we identify the need for additional research, primarily in the form of larger scale comparisons across cultural groups of patterns of participation and interaction, but also in the form of case studies that can be submitted to microanalyses of the form as well as the content of communicator’s participation and interaction online

Do (and say) as I say: Linguistic adaptation in human-computer dialogs

© Theodora Koulouri, Stanislao Lauria, and Robert D. Macredie. This article has been made available through the Brunel Open Access Publishing Fund.There is strong research evidence showing that people naturally align to each other’s vocabulary, sentence structure, and acoustic features in dialog, yet little is known about how the alignment mechanism operates in the interaction between users and computer systems let alone how it may be exploited to improve the efficiency of the interaction. This article provides an account of lexical alignment in human–computer dialogs, based on empirical data collected in a simulated human–computer interaction scenario. The results indicate that alignment is present, resulting in the gradual reduction and stabilization of the vocabulary-in-use, and that it is also reciprocal. Further, the results suggest that when system and user errors occur, the development of alignment is temporarily disrupted and users tend to introduce novel words to the dialog. The results also indicate that alignment in human–computer interaction may have a strong strategic component and is used as a resource to compensate for less optimal (visually impoverished) interaction conditions. Moreover, lower alignment is associated with less successful interaction, as measured by user perceptions. The article distills the results of the study into design recommendations for human–computer dialog systems and uses them to outline a model of dialog management that supports and exploits alignment through mechanisms for in-use adaptation of the system’s grammar and lexicon

Fearsquare: hacking open crime data to critique, jam and subvert the 'aesthetic of danger'

We present a critical evaluation of a locative media application, Fearsquare, which provocatively invites users to engage with personally contextualized risk information drawn from the UK open data crime maps cross-referenced with geo-located user check-ins on Foursquare. Our analysis of user data and a corpus of #Fearsquare discourse on Twitter revealed three cogent appraisals ('Affect', 'Technical' and 'Critical') reflecting the salient associations and aesthetics that were made between different components of the application and interwoven issues of technology, risk, danger, emotion by users. We discuss how the varying strength and cogency of these public responses to Fearsquare call for a broader imagining and analysis of how risk and danger are interpreted; and conclude how our findings reveal important challenges for researchers and designers wishing to engage in projects that involve the computer-mediated communication of risk

Communicating, learning and the in-between: a study of the impact of open-access, informal online learning environments

1. The broad aim of this project has been to contribute understandings of the uses of computer-mediated communication in 'informal' (not leading to certification) yet institutionally-hosted online spaces. The project consisted of an investigation into engagement with communication and discussion tools provided by OpenLearn, the Open University's Open Content Initiative (http://www.open.ac.uk/openlearn). 2. The research focused on a selection of examples of asynchronous and synchronous communication situations within OpenLearn, including a selection of forums from the LearningSpace (http://openlearn.open.ac.uk) and various instances of synchronous communication using FM (FlashMeeting) that took place within the context of two pilot studies organised by the researcher in coordination with discipline-based colleagues. 3. Whilst the research was based on an action research orientation, the approach was predominantly exploratory and ethnographic methods (observation and participant observation) were used, complemented with semi-structured interviews, as appropriate. Thematic analysis was used within a grounded theory approach. 4. The study suggests 5 themes as core elements of engagement in CMC within an OER context: 'validation�; 'privacy�; 'trust�; 'purposefulness�; 'leadership'. The themes are mutually-dependent and each warrants more detailed investigation, and relevant topics are discussed. 5. In short, the study provides a contribution to enquiries on the impact of OERs in that it brings to light, from within a sample of learning situations across the 'informal�/�formal' space, a number of boundary issues concerning curriculum and, in particular, pedagogy. It suggests that a major aspect of the impact of OERs is that their availability is not only creating new challenges but also uncovering previously veiled tensions and questions regarding identity and boundaries. 6. A number of outputs have been generated, including two new projects that capitalise on understandings facilitated during the pilots carried out within the remit of this study

The evolution of a cooperative work framework for e-Learning

This paper details the evolution of a Framework for e-Learning, to a Cooperative Work Framework for e-Learning, as presented at the IASK conference (Graham 2008a) and annotated accordingly. It begins by discussing the development of the original Framework for e-Learning, and how this study resulted in a further study investigating whether the use of Blended Learning could fulfill or at least accommodate some of the human requirements presently neglected by current e-Learning systems as identified by the original Framework. This second study evaluated an in-house system: Teachmat, and discussed how the use of Blended Learning had become increasingly prevalent as a result of the enhancement and expansion of Teachmat. It looked at the employment of Blended Learning and Teachmat’s relationship to human and pedagogical issues, as well as both the positive and negative implications of this reality. PESTE factors from Sociology were then applied to appraise the adoption of e-Learning, leading to the proposal of PESTE factors for educational software and e-Learning in particular. Finally, the study evolved to reconsider e-Learning in relation to a Cooperative Work Framework, revealing critical weakness in the fundamental nature of e-Learning and its consequent propensity for failure
