Relation of resemblance in information retrieval     

Pirkko Pietiläinen 《Information processing & management》1982,18(2):55-59

A method using the amount of semantic information of query terms as weight in a fuzzy relation of resemblance is presented. The relation can be used to partially order documents in decreasing order of resemblance with the query. Large operational bibliographic data bases are used to test the validity of the approach.  相似文献

Hirsch-type characteristics of the tail of distributions. The generalised h-index     

Wolfgang Glänzel  András Schubert 《Journal of Informetrics》2010,4(1):118-123

In this paper a generalisation of the h-index and g-index is given on the basis of non-negative real-valued functionals defined on subspaces of the vector space generated by the ordered samples. Several Hirsch-type measures are defined and their basic properties are analysed. Empirical properties are illustrated using examples from the micro- and meso-level. Among these measures, the h-index proved the most, the arithmetic and geometric g-indices, the least robust measures. The μ-index and the harmonic g-index provide more balanced results and are still robust enough.  相似文献   

Is Education Getting Lost in University Mergers?     

Jani Ursin  Helena Aittola  Charles Henderson  Jussi Välimaa 《Tertiary Education and Management》2013,19(4):327-340

Mergers are common phenomena in higher education institutions. Improving educational quality is typically one of the stated goals of university mergers. Yet, little information exists about how merging institutions approach this goal. This paper presents results from a study of planning documents created prior to four mergers in the Finnish higher education system. These documents show that there was little concrete attention given to the educational issues related to the mergers. Most attention was placed on administrative issues and issues related to research. When educational issues were mentioned, it was almost always in the form of vague goals with few details provided about how the goals were to be reached. We conclude that this lack of attention to the educational aspect of mergers is a significant weakness of the planning process in these mergers.  相似文献   

Berufliche Weiterbildung – Gelegenheits- und Teilnahmestrukturen     

Dr. Katrin Kaufmann  Dipl.-Päd. Sarah Widany 《Zeitschrift für Erziehungswissenschaft》2013,16(1):29-54

This contribution starts out from the assumption that participation in continuing professional education is realized in the context of different opportunity structures and an analysis of participation selectivity must take account of both self-selection and external selection processes. The different opportunity structures are described using approaches from segmentation and economic theory, which lead to the identification of three segments of continuing professional education. Participation structures in the three training segments are shown using logistic regressions, which take account of socio-demographic and individual characteristics of the social and employment environment. These predictors display segment-specific influences, which emphasizes the importance of differentiated perspectives on continuing professional education. Overall, participation is shown to be clearly influenced by external selection processes. The basis of the analyses is data from the German National Educational Panel Study (NEPS), cohort 2009/10.  相似文献   

Teachers’ professional agency and learning – from adaption to active modification in the teacher community     

Kirsi Pyhältö  Janne Pietarinen  Tiina Soini 《Teachers and Teaching》2013,19(7):811-830

The aim of this study was to examine teacher learning in terms of teachers’ professional agency in the professional community of the school. Altogether 2310 Finnish comprehensive school teachers completed a survey. Results showed that teachers’ active efforts to learn in the professional community and to promote school development cannot be explained, and hence reduced, to a single behavioral attribute. The findings indicated that teacher learning in terms of professional agency in the professional community consists of several elements including: skills, efficacy beliefs, and motivational factors, which entail transforming one’s teaching practices, experiencing collective efficacy, constructing positive interdependency, the appreciation of mutual agreements, and using active strategies of help-seeking. The investigation also suggests that the use of modifying strategies is characteristic of both the teacher’s professional agency as well as the strategies employed to reduce stress.  相似文献   

Teachers’ dilemmatic decision-making: reconciling coexisting policies of increased student retention and performance     

Charlotte Jonasson  Åsa Mäkitalo  Klaus Nielsen 《Teachers and Teaching》2013,19(7):831-842

In recent years, many countries within the Organisation for Economic Co-operation and Development have formulated educational policies aimed at providing better education to more students. However, this may be perceived as constituting dilemmatic spaces, where teachers must make efforts to reconcile coexisting political demands in their everyday work. The purpose of this article is to provide insight into how teachers handle coexisting educational policies of increased student retention and performance. Empirical findings from a one-year field study at a Danish vocational school explore how teachers’ decision-making as response to coexisting demands of increased student retention and performance involves the development of various pedagogical approaches to the students: an active ‘caring’ approach, a passive ‘wait until this class is over’ approach, an active ‘vocational gate-keeping’ approach, and a passive ‘wait and see whether they drop out’ approach. Based on the findings, it is argued that the various pedagogical approaches are developed through social negotiations with leaders, students, and other teachers. Moreover, these pedagogical approaches lead to the development of further negotiated, dilemmatic decisions to be made. Thus, a dynamic approach to teachers’ dilemmatic decision-making is proposed.  相似文献   

Not Read,but Nevertheless Solved? Three Experiments on PIRLS Multiple Choice Reading Comprehension Test Items     

Jörn R. Sparfeldt  Rumena Kimmel  Lena Löwenkamp  Antje Steingräber  Detlef H. Rost 《Educational Assessment》2013,18(4):214-232

Multiple-choice (MC) reading comprehension test items comprise three components: text passage, questions about the text, and MC answers. The construct validity of this format has been repeatedly criticized. In three between-subjects experiments, fourth graders (N ₁ = 230, N ₂ = 340, N ₃ = 194) worked on three versions of MC items from the Progress in International Reading Literacy Study 2001 reading comprehension test with relevant components successively deleted: “original version” (text, questions, MC-answers), “version without text” (questions, MC-answers), “version without text and without questions” (only MC-answers). Answering correctly the MC items became more difficult as the relevant information was eliminated. In the two narrative fictional texts presented, the students' performance of the version without text was not better than chance. Conversely in the informational (fictional) text, the students' performance of the version without text was better than chance. In the third condition, students' performance was never better than chance.  相似文献   

Tracing discursive processes of shared knowledge construction in a technology-enhanced higher education setting     

Maarit Arvaja  Johanna Pöysä-Tarhonen 《Interactive Learning Environments》2013,21(4):321-337

This study focused on combining both the group- and individual-level analyses in studying a collaborative activity in technology-enhanced interactions in a higher education setting. The aim was to make visible, with empirical examples, the quality of the students' web-based discussions and trace the route for shared understanding. By quantifying various communicative functions, the analysis provided general knowledge on the quality and purpose of the discussion in the group and highlighted the different functional positions each student had within the group. However, only a detailed interpretative analysis of the relationships between specific thematic contents, communicative functions, and the collaborative features of the discussion, in the temporal frame, made it possible to trace and gain a deeper understanding of the true acts of collaboration. It also highlighted the individual participants' different participatory and discursive positions in the different phases of the task. Over the study, it became evident that any attempts to define a collaborative activity from either the group's or individual's perspective would only result in a partial interpretation of the collaborative enterprise.  相似文献
