Somerset Computing Limited has developed a unique search engine that allows publishers and societies to produce electronic archives with full‐text searching and the ability to carry out high‐level search requests without major rekeying or tagging, making it the most cost‐effective solution for full‐text searching available. This technology has relevance to many publishing areas including legal publishers, academic publishers, STM publishers, learned societies and professional typesetters. This article describes how Somerset Computing has utilized its expertise and this innovative in‐house software to provide the British Academy with an affordable, fully searchable solution to the electronic archiving of the Proceedings of the British Academy. 相似文献

A method for uncovering students’ thinking about thinking, specifically their meta-strategic knowledge, is explored within
the context of an ongoing, multi-year intervention designed to promote the development of students’ thinking dispositions.
The development of a concept-map instrument that classroom teachers can use and an analytic framework for interpreting students’
responses is presented. In a preliminary study, the concept map instrument is piloted to evaluate changes in students’ conceptions
of thinking after a year’s participation in classrooms where their teachers actively sought to make thinking more visible
by noticing and naming the thinking observed as well as introducing and using thinking routines (Ritchhart and Perkins. Educational
Leadership, 65(5), 57–61 2008). Concept maps from 239 students from grades 3 through 11 were analyzed. Results suggest that students’ conceptions of thinking
do improve with age but also can be substantially developed through a classroom culture where thinking is modeled and rich
opportunities for thinking are present. The concept map instrument itself proved to be a robust instrument for uncovering
students’ thinking about thinking. 相似文献

Involvement in a number of action-learning programmes and associated development opportunities has led the Professional Development Centre Limited to question the relevance of a strict adherence to the ‘rules’ of action learning as described by Reg Revans. A deliberate focus of one such programme to a financial services organisation offered some insights into the challenges of introducing action learning into the field. Pressures on organisations of time and business expedients might make them believe that action learning is too slow a technique to offer real rewards. However, elements of the action-learning story do resonate in the workplace, key concepts that appear to ‘stick’ are listening, questioning and equality. The utilisation of these skills enhances leadership and organisational development and can still provide a useful set of actions to aim for. This is especially true in problem solving and the way in which respect and equality can re-create a different environment or development space. 相似文献

OBJECTIVE: To understand to the degree to which a broad variety of victimizations, including child maltreatment, conventional crime, peer, and sexual victimizations, persist for children from 1 year to the next. DESIGN: A national sample of 1467 children aged 2-17 recruited through random digit dialing and assessed via telephone interviews (with caretakers and youth themselves) about a comprehensive range of victimization experiences in the previous year, and then re-assessed (72.3% of baseline sample) after a 1-year interval. RESULTS: The risk for re-victimization in Year 2 was high for children victimized in Year 1, with risk ratios ranging from 2.2 for physical assault to 6.9 for sexual victimization. Victimization of any one type left substantial vulnerability even for different types of subsequent re-victimization (e.g., property crime victimization was associated with higher risk of sexual victimization the next year). Children with four or more types of victimization in Year 1 ("poly-victims") were at particularly high risk of persisting poly-victimization. Persisting poly-victimization was more likely for children who scored high on anger/aggression and who had recent life adversities. Desistence from poly-victimization was associated with having more good friends. Onset of poly-victimization in Year 2, in contrast to persistence from Year 1, was associated with violent or maltreating families, family problems such as alcohol abuse, imprisonment, unemployment and family disruption. Having more older siblings acted as both a risk factor and a protective factor for different groups of youth. CONCLUSION: Children previously victimized in 1 year are at higher risk of continued victimization, and the poly-victims are at particular risk. These findings suggest the potential merit of identifying these high-risk children and making them priority targets for prevention efforts. 相似文献

Previous research has demonstrated the importance of examining the instructional efficiency of academic interventions and has defined efficiency as the number of items learned per instructional minute. Maintenance of the skill is also an important instructional goal, however. Therefore, the current study compared efficiency metrics using initial learning and maintenance with 25 fourth‐grade students. Each student was taught the pronunciation and English translation of 12 words from the Esperanto international language with two instructional conditions (six words for each condition). The first condition was traditional drill (TD) rehearsal with all unknown words, and the second was incremental rehearsal (IR) with one unknown and eight known words. Results indicated that, although the IR condition led to significantly more words being retained, TD was significantly more efficient using initial learning. The two conditions were equally efficient, however, when maintenance data were used. Therefore, evaluating the efficiency of instructional interventions should consider maintenance data as well. © 2009 Wiley Periodicals, Inc. 相似文献

The analysis of classroom observation data is seen as increasingly important in research on the impact of high‐stakes language tests or new foreign‐language programmes on students, teachers and other stakeholders. Video‐recordings of language teaching and learning in classrooms impacted by such tests or programmes can provide revealing data, which, however, may be difficult to analyse in raw recorded form. The organisation of video‐recordings into an interactive database facilitates the retrieval and analysis of data in response to particular research questions. Informed by current research on the use of video in education, especially educational research, and by the relevant video database literature, this paper describes a video database developed by the University of Cambridge English for Speakers of Other Languages (Cambridge ESOL) Examinations operation, part of Cambridge Assessment, the new identity of the University of Cambridge Local Examinations Syndicate (UCLES). This paper describes three Cambridge ESOL impact studies for which the data were collected, and discusses the video‐recording equipment used, approaches adopted and decisions made. It then outlines the aims, principles and approaches involved in the development of the impact research video database, including software selection, main design features and envisaged future uses. A step‐by‐step account for the likely video database user is included, along with sample screenshots. 相似文献
