BACKGROUND: The National Library for Health offers a comprehensive searchable database of nationally approved clinical guidelines, called the Guidelines Finder. This resource, commissioned in 2002, is managed and developed by the University of Sheffield Health Sciences Library. METHODS: The authors introduce the historical and political dimension of guidelines and the nature of guidelines as a mechanism to ensure clinical effectiveness in practice. The article then outlines the maintenance and organisation of the Guidelines Finder database itself, the criteria for selection, who publishes guidelines and guideline formats, usage of the Guidelines Finder service and finally looks at some lessons learnt from a local library offering a national service. CONCLUSIONS: Clinical guidelines are central to effective clinical practice at the national, organisational and individual level. The Guidelines Finder is one of the most visited resources within the National Library for Health and is successful in answering information needs related to specific patient care, clinical research, guideline development and education. 相似文献

We reply to the criticism of Opthof and Leydesdorff on the way in which our institute applies journal and field normalizations to citation counts. We point out why we believe most of the criticism is unjustified, but we also indicate where we think Opthof and Leydesdorff raise a valid point. 相似文献

Abstract Burton Clark, in Creating Entrepreneurial Universities, defined the characteristics of what he named ‘innovative universities’. The paper considers these characteristics ‐ particularly such universities' willingness to adapt to changing environments and how they seek to do so. It identifies the challenges facing universities and considers why universities need to adapt their research, teaching and learning, and knowledge transfer. Innovative universities do seek to escape history — they adapt to change. 相似文献

In this study the learning process of 12 Dutch novice university teachers was monitored during a five-month induction programme. The teachers were interviewed before and after the programme and were asked to fill in several email logbooks during the programme. A change process was identified, in which experiencing and experimentation played a central role. In particular, modelling by the teacher educator, the observation of video cases, reflection on these with peers and experiencing success in their own practice seemed to be important incentives that encouraged teachers to adopt and eventually implement new pedagogical approaches. On the basis of our data, we think that teachers' conceptions and teaching practice are best developed simultaneously and that the design of induction programmes should support this process. 相似文献

So far scholars have researched beliefs about knowledge, knowing, and learning mainly in the areas of science and mathematics and among secondary school students. In this article, we explore primary school students' metacognitive beliefs about religious education. The article reports on a study involving 656 fifth- and sixth-grade students. We investigated their metacognitive beliefs, how these beliefs interrelate, and which students agree with which beliefs. In the minds of young students 7 categories are discernible: realistic learning, the transformative power of religion, social learning, intrinsic task value motivation, learning satisfaction motivation, the teacher's empathic orientation to learning, and the teacher's respect for students' contributions. These categories and their interrelationships open up new perspectives for the construction of a metacognitive beliefs system and for an interconnected network of beliefs across domains. We also outline implications for religious education in schools. 相似文献

In this study, the effects of a school improvement program on cooperative learning (CL) with respect to the elaborations of 6th-grade students working in mixed-ability and mixed-sex dyads on 2 cooperative tasks were examined. A posttest-only design with a control group was used to investigate the provision and receipt of elaborations within the dyads and the performance of the dyads working on cooperative mathematics and language tasks. Treatment dyads were found to exchange significantly more high-level elaborations during the language task than the control dyads. The treatment dyads also tended to produce higher performance scores on the 2 tasks. 相似文献

This article describes the construction of a hierarchical taxonomy of metacognitive activities for the interpretation of thinking-aloud protocols of students in secondary education, who studied texts on history and physics. After testing an initial elaborate taxonomy on a restricted number of protocols by multiple raters, it appeared that the interrater correspondence was well below par. The categories in the taxonomy were too highly specified. Categories were combined and tested on new protocols in a cyclic fashion. The revised taxonomy was then used for coding 16 history protocols and 16 physics protocols. Frequencies of occurrence of metacognitive activities were obtained, as well as judgements of the quality of the metacognitive activities of the participants. There is a reasonable correlation between the frequency method and the quality method for coding thinking-aloud protocols. Also, there is a substantial covariation of the number of metacognitive activities across both tasks. 相似文献

Forming a science-oriented identity is considered a process underlying both interest and achievement in science education. A questionnaire is developed for describing “identities as learners” and evaluating their science orientedness. The instrument (k = 65) focuses on cognitive aspects. An internal coherence of .88 was found. Five subscales were defined that proved interrelated yet distinguishable. A pilot amongst 40 students from Dutch general secondary education showed that preferring science over non-science subjects and relatively high grades for sciences subjects were strongly correlated to science orientedness of the learner identity (rs = .65; p < .001). The results support the reliability and validity of the questionnaire but also point to the importance of identity as a central concept in studying science education. It is concluded that we made a promising step in constructing an instrument for monitoring the development of cognitive aspects of science-oriented identities during (innovative) science education. 相似文献

Teacher educators’ collaboration plays an important role in the improvement of teacher education. Many studies in educational research focus on collaboration from 1 particular perspective. A focus on 2 perspectives, a qualitative (focusing on collaborative activities) as well as a quantitative (focusing on relations) perspective, and relating both perspectives, can add to our knowledge. Data were collected in 3 subject departments of a teacher education institute. Findings indicated that educators’ collaborative networks inside the departments could gain from more coherent and dense relations, and that key players were important to support and sustain collaboration. Both perspectives were mildly related, correlations were found for “degree” and “information” (r = .31, p < .05), “degree” and “joint work” (r = .38, p < .01), and “reciprocity” and “joint work” (r = .33, p < .05), no correlations were found for “degree” or “reciprocity” and “discussing”. At the department level, only mathematics showed significant correlations. Results indicated that, in further research, qualitative aspects as well as quantitative aspects should be included. 相似文献
