The fundamental idea of the work reported here is to extract index phrases from texts with the help of a single word concept dictionary and a thesaurus containing relations among concepts. The work is based on the fact, that, within every phrase, the single words the phrase is composed of are related in a certain well denned manner, the type of relations holding between concepts depending only on the concepts themselves. Therefore relations can be stored in a semantic network. The algorithm described extracts single word concepts from texts and combines them to phrases using the semantic relations between these concepts, which are stored in the network. The results obtained show that phrase extraction from texts by this semantic method is possible and offers many advantages over other (purely syntactic or statistic) methods concerning preciseness and completeness of the meaning representation of the text. But the results show, too, that some syntactic and morphologic “filtering” should be included for effectivity reasons. 相似文献

ABSTRACT This article presents the study of the main phenomena of material weathering and structural damage that affect traditional architecture built in adobe, analysing the damage found in 553 case studies, representative of different technical varieties of adobe construction in Spain. The analysis methodology proposed in this text made it possible to quantify and identify the risks of damage appearing, establishing its impact and identifying its main mechanisms and causes. At the same time, the behaviour of adobe construction systems was further studied, observing how specific modifications in technique can promote or hinder deterioration and establishing the probable causes of the different responses to these phenomena. 相似文献

An impediment to conducting high-quality quantitative research studies in education is the paucity of valid measures of learning gains. Studies often seek to investigate students’ deep, conceptual understanding yet many measures assess only surface, procedural understanding. One reason is that the development of validated measures of conceptual understanding is resource intensive and time consuming, and success is not guaranteed. We evaluated a novel and efficient technique, based on comparative judgement, for assessing conceptual understanding. We applied the technique to a randomised controlled trial in which students were taught simple algebra based on either the Grid Algebra or the MiGen software package. The participants were Year 5 students (N = 188) drawn from four primary schools who had not encountered algebra previously. An instrument from the literature (Concepts in Secondary Mathematics and Science: Algebra Scale) and a novel comparative judgement assessment were administered following the intervention. Students in the Grid Algebra condition outperformed those in the MiGen condition on both post-test measures. The comparative judgement technique performed similarly to the standard instrument but was far more efficient to design and implement. The technique can, in principle, be quickly applied to any target concept of interest. We conclude that comparative judgement is a valid, reliable and practical tool that could help to increase both the quantity and quality of quantitative research in education. 相似文献

This article reports on a small-scale investigation of how teachers organise goal-oriented learning in Swedish preschools. The revised Swedish curriculum (National Agency for Education 2011) highlights the need for children to develop their mathematics skills through activities that integrate play and learning. This study investigates how different types of activities contribute to children developing their understanding of the concepts ‘half’ and ‘double’. Three preschool teachers participated in a developmental project in which they conduct teaching in accordance with the Variation Theory of Learning. The pedagogical contexts they bring into being reveal important insights for early childhood education. The pedagogical context that can be realised in the planned activities limits or favours the learning process and the success of the theoretical aspirations for the session. This article discusses the idea of ‘teaching’ and how to facilitate conceptual development in a goal-oriented but child-centred practice. The main results show that play is central in early childhood education, and that problem-solving as a means for mathematics education needs to be problematised and used with sensitivity to the children's intentions and perspectives. 相似文献

The Library of Congress’ Cataloging in Publication (CIP) Program has been in existence for forty years. During this time, the CIP Program has moved from a model where the Library of Congress created all pre-publication metadata for publishers to a partnership where other libraries share in the creation of metadata. This article documents the evolution of the Electronic Cataloging in Publication (ECIP) Cataloging Partnership Program. The ECIP Cataloging Partnership Program can be used as a model to leverage limited resources across libraries to the benefit of library users nationwide. 相似文献

AbstractThe Electronic Cataloging in Publication (ECIP) Cataloging Partnership Program began in 2004. It is a collaboration between the Library of Congress (LC) Cataloging in Publication (CIP) Program, publishers, and libraries across the United States. System set-up for the program proved challenging for library partners. A survey was conducted during February 8–March 6, 2018 to learn about ECIP partners’ ECIP set-up experience. The findings show that communication and training documentation are two key elements for the program to be effective and successful. The survey results helped the LC CIP program develop a new and improved ECIP system. 相似文献

Introductory thermodynamics is a topic which is covered in a wide variety of science and engineering educations. However,
very different teaching traditions have evolved within different scientific specialties. In this study we examine three courses
in introductory thermodynamics within three different scientific specialties: physics, chemical engineering and mechanical
engineering. Based on a generalization of Kuhn’s theory of disciplinary matrix, and the idea of boundary objects we analyse
how basic thermodynamics theory is conceived in the different scientific specialties. The study is based on interviews with
teachers and analysis of the different textbook traditions. It is concluded that teachers need to take into account how subject
matter is conceived in other related scientific specialties when designing courses. Two examples demonstrating how this may
be done are given.

Issues concerning children and young people are of interest for the educational field as question about fostering, up-bringing,
learning and socialisation are core topics for academic researchers in education. Today many young people in Sweden and around
the world spend an increasing amount of their time in online communities or social networking sites. This article aims to
investigate whether it also is highlighted by the education researchers. Is it an area to which educational researchers currently
contribute? The goal for this article is to present research that is done regarding these issues. My findings show that few
academic studies deal with youth and their online environments. Foremost is the research about Information and Communication
Technology (ICT) in formal learning situations: in higher education, in schools and classrooms, among professional groups
such as teachers and about more general computer use rather than on questions about the fostering or up-bringing of children
online. This study implies that online activities for children and young people is a topic currently lying outside the educational
research field, resulting in a discussion on why that can be. My work consisted of three parts: a manual search in Swedish
research journals at a university library and by searching one Swedish (Libris) and one international (ISI Web of Science)
online database. This activity took place in 2009 and covered research conducted between 2003 and 2008. I conclude that this
area is one where educational expertise is lacking; hence further research is strongly required. 相似文献
