Computer Supported Collaboration: Is the Transfer of Cognitive Structures Mediated by Mode of Communication?

The objective of this study was to observe evidence of structural transfer among subjects in a group problem-solving activity and determine whether mode of collaborative technology or use of a priming agent affected the nature of transferred structures. Evidence for structural transfer is found in three theoretical perspectives: organizational ditransitive (linguistic) verb structures, adaptive structuration theory, and mental model transfer theory. Dependent variables included various grammatical structures and coefficients derived from pretest and posttest scores on David Kolb's Learning Styles Inventory, modified for the experiment. The combination of changes in grammatical frequencies and learning style may suggest that one or more media or the priming agent may affect structural transfer. Results indicate that groups using the GroupSystems collaborative technology produced less overall linguistic content than did subjects using a generic chat system, but employed more complex language as indicated by frequency of the organizational ditransitive verb structure. Also, subjects supplied with an organization chart (priming agent) during the group problem-solving session experienced greater change on the learning styles inventory than did those participating in the session without the chart. These findings suggest that mode of communication and use of priming agents may contribute positively or negatively to the transfer of structures among group members. Researchers, collaborative system designers, organizational leaders, trainers & educators, and frequent collaborative technology system end-users should be aware of these potential affects. Suggestions for future research are provided. Relationship of theoretical foundations of structural transfer to constructivism is discussed

Backfiring and favouring:how design processes in HCI lead to anti-patterns and repentant designers

Design is typically envisioned as aiming to improve situations for users, but this can fail. Failure can be the result of flawed design solutions, i.e. anti-patterns. Prior work in anti-patterns has largely focused on their characteristics. We instead concentrate on why they occur by outlining two processes that result in anti-patterns: 1) backfiring, and 2) favouring. The purpose of the paper is to help designers and researchers better understand how design processes can lead to negative impacts and to repentant designers by introducing a richer vocabulary for discussing such processes. We explore how anti-patterns evolve in HCI by specifically applying the vocabulary to examples of social media design. We believe that highlighting these processes will help the HCI community reflect on their own work and also raise awareness of the opportunities for avoiding anti-patterns. Our hope is that this will result in fewer negative experiences for designers and users alike

Interactive tabletops in education

Interactive tabletops are gaining increased attention from CSCL researchers. This paper analyses the relation between this technology and teaching and learning processes. At a global level, one could argue that tabletops convey a socio-constructivist flavor: they support small teams that solve problems by exploring multiple solutions. The development of tabletop applications also witnesses the growing importance of face-to-face collaboration in CSCL and acknowledges the physicality of learning. However, this global analysis is insufficient. To analyze the educational potential of tabletops in education, we present 33 points that should be taken into consideration. These points are structured on four levels: individual user-system interaction, teamwork, classroom orchestration, and socio-cultural contexts. God lies in the detail

Rediscovering the IT productivity paradox : the alignment and dynamics of IT-enabled change

There is a growing recognition that sustainable competitive advantage requires a viable integration between information technology (IT) and organisational change. Increasingly, firms are interested in the transfer of IT-related best practices in the hope that fundamental organisational change will thereby be achieved. However, the investment in IT is often disproportionate to the benefits obtained. This issue of what has been referred to as the IT productivity paradox requires a re-examination of the organisational dynamics rather than a mere proclamation of the insufficiency of best practices. In this study, the re-examination is based on the viewpoint of alignment and contextualism. To achieve this aim, the study is divided into two phases. Phase one uses five cases to investigate the alignment behaviour of organisational change, and proposes four change patterns. Phase two uses one in-depth case study to explore the problem of IT-enabled change backfire and enhance the contextualism perspective of change in terms of four propositions (underlying logic, reciprocal causality, time effect and frame awareness). This conceptualisation offers a socialscientific perspective on the analysis of the IT productivity paradox, and draws out the practical implications for change management based on a "reflective transfer" model that complements the planned approach. The research adds to current understanding of the IT productivity paradox by highlighting the importance of the alignment and dynamics of organisational change
