This empirically driven paper is about workplace learning with specific focus on the ‘work’ of consuming practices. By consuming we refer to the eating, and the drinking, and (at times) to the smoking that workers, in most organisations, do on a daily basis. Indeed, it is the quotidian nature of consuming, coupled with its absence from workplace learning research that make them noteworthy practices to explore. In using the term practice we draw on the recent tranche of practice based theorisations: notably Schatzki (1996, Organization Studies, 26(3), 465-484, 2005, Organization Studies, 27(12), 1863-1873, 2006) and Gherardi (Human Relations, 54(1), 131-139, 2001, 2006, Learning Organization, 16(5), 352-359, 2009). The paper frames consuming practices as ‘dispersed’ (general) practices and, illustrated through empirical data from multiple projects, we progressively outline how these contribute to the learning of ‘integrative’ (specialized work) practices. Our overall aim is to (re)position consuming practices from prosaic, to having much relevance for research on workplace learning.  相似文献

Herman Witkin's research in differentiation theory proposed a conceptual framework describing the cognitive style known as field dependence‐independence. The operational measures of this construct are restructuring skills and interpersonal competencies, and were originally conceived to be fixed in an individual. A recent reconceptual‐isation, however, suggested that there may be some malleability in learning strategies that flow from cognitive style. Learners predisposed to field dependence might gain access to restructuring skills brought to problem‐solving situations by field independents. This study undertook to examine the effects and practicability of restructuring training as a means of addressing individual learner differences. Field independent subjects significantly out‐scored field‐dependent subjects on all three test tasks in the control group. Experimental group field independents did not significantly outscore experimental field dependents. Training enhanced field dependent subject performance on two dependent measures tasks. There was interaction across treatment and field dependence on all three dependent measures.  相似文献

Metrics derived from user visits or sessions provide a means of evaluating Websites and an important insight into online information seeking behaviour, the most important of them being the duration of sessions and the number of pages viewed in a session, a possible busyness indicator. However, the identification of session (termed often ‘sessionization’) is fraught with difficulty in that there is no way of determining from a transactional log file that a user has ended their session. No one logs out. Instead a session delimiter has to be applied and this is typically done on the basis of a standard period of inactivity. To date researchers have discussed the issue of a time out delimiter in terms of a single value and if a page view time exceeds the cut-off value the session is deemed to have ended. This approach assumes that page view time is a single distribution and that the cut-off value is one point on that distribution. The authors however argue that page time distribution is composed of a number of quite separate view time distributions because of the marked differences in view times between pages (abstract, contents page, full text). This implies that a number of timeout delimiters should be applied. Employing data from a study of the OhioLINK digital journal library, the authors demonstrate how the setting of a time out delimiter impacts on the estimate of page view time and the number of estimated session. Furthermore, they also show how a number of timeout delimiters might apply and they argue that this gives a better and more robust estimate of the number of sessions, session time and page view time compared to an application of a single timeout delimiter.  相似文献

Over the last decade universities have been subjected to various forms of academic accountability designed to maintain or improve the quality of their teaching and learning. A shared perspective of many of these accountability processes is that universities should become skilled at creating knowledge for the improvement of teaching and learning, and at modifying their behavior to reflect this new knowledge. In short, that universities should become “learning organizations.” What are the organizational characteristics of an academic learning organization? The paper will address this question by reviewing the adaptations in organizational structure and governance reported by universities attempting to improve the quality of their teaching and learning processes.  相似文献

The situated development of South Asian communities in the UK has led to the growth of a number of schools in which ‘ethnic minority’ pupils form a majority. Such a situation throws into higher relief issues and concerns surrounding cultural transmission and encounter, and communicative competence.

This paper recounts some of the principal findings of research in which the teaching staff of a large 9‐13 middle school were interviewed individually regarding their perceptions of their South Asian pupils. The school has an almost wholly South Asian intake and is situated near the centre of a large northern city.

The teachers’ markedly deficit view of their charges is detailed and this is followed by an explanation of their constructions in microsociological terms. A model is presented which clarifies the processes by which close intercultural interaction seem to accomplish worlds as divergent.

The author teaches children with special educational needs at the school in which the study was undertaken.  相似文献

The authors assessed the effects of using “none of the above” as an option in a 40-item, general-knowledge multiple-choice test administered to undergraduate students. Examinees who selected “none of the above” were given an incentive to write the correct answer to the question posed. Using “none of the above” as the keyed option made items much more difficult (d = ?1.11). Furthermore, 45% of the time that examinees correctly selected “none of the above,” they wrote either a wrong answer (19%) or no answer (26%), and rescoring items to deny credit in these cases caused item discrimination to fall (d = ?0.35). Thus, when “none of the above” is the keyed option, credit earned by examinees with knowledge deficiencies can make items appear to have more discriminatory power than is actually the case. The authors recommend that “none of the above” should not be used as an option in multiple-choice items.  相似文献

This study begins the task of mapping out the domain of valid, potentially helpful beliefs of students and raises the possibility of drawing on these intuitions in teaching conceptual material. Some issues are explored surrounding the identification of such intuitions, referred to as anchoring conceptions or anchors. We attempt to: (1) propose some organizing theoretical and observational definitions of the anchor construct; (2) present some initial findings from a diagnostic test designed to uncover anchors for physics instruction; and (3) provoke an initial discussion of the new methodological issues that arise in this domain.

The results of the diagnostic test indicate that a number of group anchors exist. In addition, some unexpected non‐anchors were identified. Furthermore, evidence was found indicating that some anchoring examples may be ‘brittle’, i.e., evidence that the anchor could not be extended analogically to help a student make sense of a target situation.

Finally, it is suggested that further research is needed to construct a theory of anchoring conceptions that would, for example, specify what characteristics would indicate that an anchoring conception can provide the basis for conceptual change via analogical extension.  相似文献

The configuration of the novel three-stage L-band erbium-doped fiber amplifier with very large and flat gain and very low noise figure presented in this paper uses the forward ASE (amplified spontaneous emission) from the first section of the EDF (erbium-doped fiber) and the backward AS E from the third section of the EDF (both serve as the secondary pump sources of energy) to pump the second EDF. To improve the pump efficiency, the power of the pump is split into two parts(with a ratio of e.g. 2:7). The characteristics of this L-band EDFA are studied on the basis of the Giles Model with ASE.  相似文献
