This article presents an empirical evaluation of the validity and reliability of a peer-assessment activity to improve academic writing competences. Specifically, we explored a large group of psychology undergraduate students with different initial writing skills. Participants (n?=?365) produced two different essays, which were evaluated by their course peers and professors using a specific grading instrument (rubric). The validity of the task was demonstrated by a high inter-grader agreement and a strong degree of consistency between the ratings of the peers and professors. Although all students did not improve their writing skills between their first and second essays, the peer-assessment activity enhanced the writing abilities of low but not high-achieving participants. The pedagogical implications of these results are discussed.  相似文献

When we design information technology we risk building specific metaphors and models of human activities into the technology itself and into the embodied activities, work practices, organisational cultures and social identities of those who use it. This paper is motivated by the recognition that the assumptions about human activity used to guide the design of particular technology are made active, in use, by the interaction design of that technology. A fragment of shared design work is used to ground an exploration of different solutions to one of the technical problems that arise when technology is used to support similar work over distance. The argument is made that some solutions to design problems are better than others because they enable human interaction in different ways. Some solutions enhance the possibilities for human agency, others diminish it. This means that there can be a moral basis for choosing between alternative interaction design decisions that might otherwise be considered equivalent in terms of the functionality and usability of the technology.  相似文献

Since the 1980s there have been a number of studies that investigate the use of computers in homes. Many of these focused on the adults or adolescents in the family. Few studies have focused on children, particularly those between the ages of five and twelve. If children of these ages were included in a study they were usually situated within a study of the family and its dynamics, and often their experiences were viewed through the eyes of the adults in the family. The study described in this paper is unique in that the children's perceptions, beliefs and practices were the major focus and the children themselves were the informants. The study investigated children's computer experiences within their homes and their perceptions and beliefs about a range of issues associated with these experiences. The focus in this paper is on the range of computer activities in which children engaged. The major finding was that children's activities, whether game playing, other leisure-related activities or work-related activities, involved 'playful' interactions with the computer which led to exploratory approaches to learning about both the computer and the task itself. © 1999 IFIP, published by Kluwer Academic Publishers  相似文献

This paper proposes a strategic model for assessing the coherence between companies’ knowledge strategies and their business strategies as well as in their competitive and organisational contexts. In analysing knowledge management literature, we locate three principal strategies: (1) knowledge development (internal or external), (2) knowledge sharing (codification or personalisation) and (3) knowledge exploitation (internal or external). We then position the three strategies and six related policies in the context-content-process dimensions of Pettigrew's model to create a useful framework for strategic analysis and a model to assess the coherence of companies’ knowledge strategy. The model can be used to evaluate how an existing knowledge strategy aligns with a company's characteristics and to formulate and implement a coherent knowledge strategy based on the current competitive environment, organisational context and business strategy.  相似文献

During the mid-1990s, members of the global education community issued the Salamanca Statement that described inclusive schools as effective educational environments that also combat discrimination. Since that time, considerable progress has been made in moving students with disabilities from separate placements to inclusive settings. In the USA, nearly 10% of the school-aged population needs special education services and of that group, 96% are educated in general education classrooms 80% of the time. Placement of such large numbers of students with disabilities has increased the diversity of the student body and the complexity of teaching of core curriculum. For teachers and students to be successful, teachers need on-going professional development. This paper explores the efficacy of a Job-Embedded Professional Development (JEPD) model in six schools (urban, suburban and rural) that had made a commitment towards including all students with significant disabilities in general education core curriculum. Results are discussed for the six schools as well as for students identified as displaying behaviour disorders, autism or intellectual disabilities.  相似文献
