Objective
The purpose of this study was to investigate the relative effectiveness of three web-scale discovery (WSD) tools in answering health sciences search queries.Methods
Simple keyword searches, based on topics from six health sciences disciplines, were run at multiple real-world implementations of EBSCO Discovery Service (EDS), Ex Libris''s Primo, and ProQuest''s Summon. Each WSD tool was evaluated in its ability to retrieve relevant results and in its coverage of MEDLINE content.Results
All WSD tools returned between 50%–60% relevant results. Primo returned a higher number of duplicate results than the other 2 WSD products. Summon results were more relevant when search terms were automatically mapped to controlled vocabulary. EDS indexed the largest number of MEDLINE citations, followed closely by Summon. Additionally, keyword searches in all 3 WSD tools retrieved relevant material that was not found with precision (Medical Subject Headings) searches in MEDLINE.Conclusions
None of the 3 WSD products studied was overwhelmingly more effective in returning relevant results. While difficult to place the figure of 50%–60% relevance in context, it implies a strong likelihood that the average user would be able to find satisfactory sources on the first page of search results using a rudimentary keyword search. The discovery of additional relevant material beyond that retrieved from MEDLINE indicates WSD tools'' value as a supplement to traditional resources for health sciences researchers. 相似文献2.

The incorporation of a gender perspective in medical education aims toward better health, gender equity, and a better health care for both men and women. In this article, participants’ responses to a Dutch gender awareness‐raising project in medical education are discussed. Eighteen semi‐structured interviews were held with education directors and change agents. Resistance towards and obstacles for gender mainstreaming in medical education were implicit in four themes: (1) biomedical knowledge was perceived to be gender neutral, to which knowledge about women could be added to the body of knowledge either with or without framing them as gender issues; (2) the relevance of gender was unofficially denied by downplaying it, particularly in comparison with culture/ethnicity; (3) medical education’s social accountability was hardly mentioned and gender inequalities in health were framed as feminist political issues and not medical issues; and (4) we were urged to communicate carefully to increase acceptance and avoid overt resistance which situated gender inequalities outside the medical domain. Recommendations to change educational material were widely discussed; but specific features of gender were easily lost. This was especially true for power differences between men and women. Nevertheless, dominant systems of thought were challenged. 相似文献

The present study investigated the differences in learning gain when performing a WebQuest with a well‐defined versus an ill‐defined assignment. Twenty boys and twenty girls (mean age 11; 10), attending a special primary education school, performed two WebQuests. In each WebQuest, they performed either a well‐defined or an ill‐defined assignment. Knowledge acquisition was assessed by means of a concept map (ie, associative knowledge) and a knowledge test, based on facts concerning the subject (ie, factual knowledge). Results indicated that the learning gain on both WebQuests was higher for participants who worked on the ill‐defined assignments. In the long term, factual knowledge remained intact. The results of this study indicated that the use of WebQuest can be a valuable tool to enrich the educational curriculum in special education. 相似文献

This article aims to outline the reported experiences of practitioners in a local authority in England where, since the mid-1990s, a high proportion of teachers have undertaken professional development in the field of teaching thinking skills. The article is based on the main findings from a questionnaire survey which was carried out among first, middle and high school teachers in this area. It was intended to explore their views on the use, benefits and challenges of teaching ‘Thinking for Learning’, a term which encompasses both the use of a range of thinking skills strategies and the Community of Enquiry/Philosophy for Children approaches. The vast majority of respondents reported a range of positive effects on their pupils, including pupil motivation and cognitive, social and affective benefits. On the other hand, reported challenges mainly referred to a perceived lack of time and to some seemingly inherent difficulties in the teaching of thinking. Conclusions from this study have the potential to inform professional development practice and policy far beyond this local authority's regional boundaries, and aim to contribute to the body of knowledge about forms of education that are based on dialogue and enquiry. 相似文献

Pupil monitoring systems support the teacher in tailoring teaching to the individual level of a student and in comparing the progress and results of teaching with national standards. The systems are based on the availability of an item bank calibrated using item response theory. The assessment of the students’ progress and results can be further supported by using computerized adaptive testing where the items selected from the item bank are targeted at the specific ability level of the student. The present article discusses psychometric issues of pupil monitoring systems, such as ability estimation, the optimal construction of tests from the item bank and monitoring of progress. 相似文献

Students in many teacher education programmes experience confusion about portfolios. This study investigated whether using an analogy in the introduction of a portfolio helps teacher education students understand both the purpose of a portfolio and how to compile it. It was also investigated whether these students’ understanding correlates with their appreciation of portfolios. In the analogy, portfolios were compared with job application letters, curricula vitae and the references that are common in selection procedures for new employees. This analogy was helpful in promoting students’ understanding. Their understanding correlated with their appreciation of this instrument. 相似文献
