Is it possible to integrate ideals of general and liberal education into computer‐training programmes? To answer this question an analysis was made of computer training programmes for adults in Denmark. The results showed that the participants expressed a positive attitude towards computers and towards learning computer technology but they only expressed few and general expectations of the courses. This is problematic according to ideals of general education and of self‐directed learning. The organizers wanted to produce courses with general and enlightening contents but the form and contents of the actual courses only to a moderate degree realized the organizers’ intentions. The participants obtained a broad learning outcome. However, they only to a very moderate degree used this outcome at work or in relation to further education. The conclusion was that it is possible to integrate ideals of general and liberal education if computer training helps the participants to develop more precise intentions, if the teaching methods are modernized, and if the contents of the courses correspond better with the possibilities in the workplace. 相似文献

We analyzed gait and function of the supporting limb in participants of a marathon race at three stages: prerace, midrace (18 km), and near the end of the race (36 km). We confirmed that the most successful runners were able to maintain running speed for the duration of the race with little change in speed or gait. Speed slowed progressively during the race for those with slower race times, but stride frequency–stride length relationships remained normal for the speed they ran. These findings differ from most lab-based studies of fatigue, in which runners are forced to match a constant preset treadmill speed. Small changes in maximum ground force were seen in both slow- and fast-running participants as race end approached. 相似文献

The aim of the study is to analyze the careers of women gymnastics directors about the turn of the century in 1900. This is done by means of a collective biographical study of the women’s course at the Royal Central Institute of Gymnastics in Stockholm from 1891 to 1893. The study is based above all on unique correspondence between the members of the course, namely a correspondence book circulated among them between 1893 and 1943. This book contained a total of almost 500 letters comprising thousands of handwritten pages with detailed accounts of their professional career and family, as well as life’s positive and negative sides. The study shows that their opportunities of making a career – in Sweden and abroad – in the occupation they had received training in were good. There are several reasons for this success. Swedish gymnastics’ treatment methods were the height of fashion round about the turn of the century in 1900 and there was great demand for their services. They remained faithful to their choice of occupation, even if their career took a back seat for half of them when they married: family life and a professional career could not be combined for them. 相似文献

The article offers a retrospective reading of profiled American library educator Paul Wasserman’s seminal work The New Librarianship: A Challenge for Change (1972). The idea was to reevaluate the book’s major message about the urgency of transforming librarianship – the discipline, the profession and the institutional forms – into a field that is “proactive”, client-centered, innovation-conscious, aggressive and well aware of societal needs. Today, a similar change and innovation agenda recurs in R. David Lankes’ redefinition of the role and mission of libraries and librarians in The New Librarianship: A Field Guide (2016). Another contemporary parallel is John Palfrey’s discussion of re-conceptualizing libraries as networked platforms pursued in Bibliotech: Why Libraries Matter More Than Ever in the Age of Google (2015). The paper concludes with a brief comparison of how the three authors frame the issue of change in libraries and librarianship with a focus on basic stylistic and communicative features. 相似文献

Editorial comment and summaries English Drs Kjöllerström and Lybeck present here a brief report of their European survey of master's and doctoral dissertations in science education, undertaken subsequently to a workshop on Research in Science Education in Europe held at Malente, FR Germany in 1976. The full report of their survey has recently been published by the Institute for Science Education (IPN), Kiel, FR Germany. The article published here reports on the distribution, size and organization of science education research groups, their areas of research interest and higher degree programmes. It also surveys the main areas of science education research at master's and doctoral level undertaken during the period 1971‐1976, and the employment taken up by master's and doctoral students upon completion of their studies. 相似文献

Employing effective methods of sentence retrieval is essential for many tasks in Information Retrieval, such as summarization,
novelty detection and question answering. The best performing sentence retrieval techniques attempt to perform matching directly
between the sentences and the query. However, in this paper, we posit that the local context of a sentence can provide crucial
additional evidence to further improve sentence retrieval. Using a Language Modeling Framework, we propose a novel reformulation
of the sentence retrieval problem that extends previous approaches so that the local context is seamlessly incorporated within
the retrieval models. In a series of comprehensive experiments, we show that localized smoothing and the prior importance
of a sentence can improve retrieval effectiveness. The proposed models significantly and substantially outperform the state
of the art and other competitive sentence retrieval baselines on recall-oriented measures, while remaining competitive on
precision-oriented measures. This research demonstrates that local context plays an important role in estimating the relevance
of a sentence, and that existing sentence retrieval language models can be extended to utilize this evidence effectively. 相似文献

This paper firstly outlines some of the problems children can experience as a result of transferring from primary to secondary school. It then goes on to describe an initiative by the West Midlands Quaker Peace Education Project, Blessed William Howard Roman Catholic School in Stafford and its feeder schools to coordinate a secondary school preparation project. This involved special training for all primary pupils about to enter the school and a group of sixth formers. 相似文献

This paper provides important new insights into the reasons for the observed gap in educational attainment between children of immigrants and natives in Denmark using a dynamic discrete model of educational choices to determine at what stages of their educational careers children of immigrants face barriers to educational progression and how background characteristics affect educational choices at different points in the educational system. The main findings of the paper are that dropout rates from vocational upper secondary education are much higher among children of immigrants and that strengthening family characteristics reduces the dropout rates. However, behavioral differences and/or differences in constraints and institutional factors are also important barriers and thus determinants of the observed educational gaps as is age at immigration. 相似文献

By means of a narrative research synthesis, the aim of this article is to explore how the political dimension can or should be staged as a teaching and learning content in education for sustainable development (ESD). The study is limited to research literature dealing with the political dimension in relation to the phenomenon of conflict. Three approaches to the topic are identified: a socially critical approach (SCA), a social learning approach (SLA) and a radical democratic approach (RDA). Notably, SCA and SLA are already established in the research field, whereas RDA is a result of our synthesis. The scope of the synthesis is limited to these three approaches. We follow up the narrative research synthesis by comparing the three approaches to discern how the political dimension emerges as an educational content by using conflict as part of the teaching and learning activities. The main results are that all three approaches tend to downplay the political and produce political sameness. The article ends by suggesting possible directions for further research that would fruitfully translate the idea of the political dimension into educational settings and enrich the political dimension as a concept in ESD in both practice and research. 相似文献

A searcher’s interaction with a retrieval system consists of actions such as query formulation, search result list interaction and document interaction. The simulation of searcher interaction has recently gained momentum in the analysis and evaluation of interactive information retrieval (IIR). However, a key issue that has not yet been adequately addressed is the validity of such IIR simulations and whether they reliably predict the performance obtained by a searcher across the session. The aim of this paper is to determine the validity of the common interaction model (CIM) typically used for simulating multi-query sessions. We focus on search result interactions, i.e., inspecting snippets, examining documents and deciding when to stop examining the results of a single query, or when to stop the whole session. To this end, we run a series of simulations grounded by real world behavioral data to show how accurate and responsive the model is to various experimental conditions under which the data were produced. We then validate on a second real world data set derived under similar experimental conditions. We seek to predict cumulated gain across the session. We find that the interaction model with a query-level stopping strategy based on consecutive non-relevant snippets leads to the highest prediction accuracy, and lowest deviation from ground truth, around 9 to 15% depending on the experimental conditions. To our knowledge, the present study is the first validation effort of the CIM that shows that the model’s acceptance and use is justified within IIR evaluations. We also identify and discuss ways to further improve the CIM and its behavioral parameters for more accurate simulations. 相似文献
