Since fall 2009, reference librarians at The George Washington University's Himmelfarb Health Sciences Library have been embedded in online classes through Blackboard within the School of Nursing and School of Medicine and Health Sciences. The authors sought to determine the types of questions asked of the librarian, with the goal of informing future interactions with distance education classes to help develop a standard “protocol” for working with this population of students. Eighty-two questions were categorized and qualitatively analyzed. The findings have prompted librarians to explore tools such as Elluminate Live!, a tool that allows librarians to provide synchronous instruction within the Blackboard environment. 相似文献

The study examined US elementary teachers’ knowledge and practices in four key domains of science instruction with English language learning (ELL) students. The four domains included: (1) teachers’ knowledge of science content, (2) teaching practices to promote scientific understanding, (3) teaching practices to promote scientific inquiry, and (4) teaching practices to support English language development during science instruction. The study was part of a larger five‐year research and development intervention aimed at promoting science and literacy achievement of ELL students in urban elementary schools. It involved 32 third grade, 21 fourth grade, and 17 fifth grade teachers participating in the first‐year implementation of the intervention. Based on teachers’ questionnaire responses and classroom observation ratings, results indicated that (1) teachers’ knowledge and practices were within the bounds of acceptability but short of reform‐oriented practices and (2) grade‐level differences existed, especially between Grades 3 and 5. 相似文献

The struggle over credit for the discovery of penicillin is a powerful case study of the ability of scientific narrative to establish reputation. This paper examines the ways Alexander Fleming and Howard Florey told the story of the discovery and development of penicillin, each providing provenance for the drug and enhanced claims for personal recognition. Fleming's version incorporated familiar narratives of the intervention of chance and divine favor, heroic scientists, and the need to extract good from evil. This account, echoing themes found in British home front stories of the “Blitz,” the Battle of Britain, and the miracle of Dunkirk, appealed to a public imagination already stimulated by a wartime press. By contrast, Florey used a conventional chronology typical of scientific literature to tell his version of the discovery of penicillin, placing his work at the end of a sequence of investigations on antibiotic substances that started in the 19th century. This view of scientific development as building on the work of predecessors was an account of the penicillin story satisfying to an audience of scientific peers. That Fleming is credited in the public mind as the discoverer of penicillin is partially a result of his construction of a narrative of discovery that invited popular participation and appealed to a beleaguered nation at war. 相似文献

The orthodox supply-side human capital theory (HCT) paradigm is inadequate for understanding and adjusting to labour market volatility in UK regional economies like Wales. This article explores the role of regional labour market intermediaries (LMIs) in matching supply (skills) and demand (job opportunities) in regional labour markets. Some LMIs emerge because the HCT paradigm is failing. One Welsh LMI, Shaping the Future (StF), is explored empirically using qualitative methods. StF mainly adopted HCT tenets, but with some emergent demand-side focus. Despite helping workers adjust to labour market shocks, LMIs are not equipped to fix the structural demand-side problem of finite quality job opportunities in deindustrialized regions that accentuate skill use. A broader ‘skill eco-system’ paradigm is required, emphasising the foundational economy. 相似文献

Current high-stakes accountability mandates emphasize data use for school improvement. However, teachers often lack training for effective data use, and data is often too far removed from students to actually influence instructional practice. This qualitative case study was designed to gain a better understanding of a district-wide, teacher-centered approach to data use. Findings suggest that when data is used to “inform” instruction rather than “evaluate” instruction, teachers begin to practice reflective teaching. A common language emerged across grade levels facilitating a collaborative approach to data use. Using the theoretical framework of Self-Determination Theory, we propose a data informed instructional theoretical model that stakeholders in K-12 education systems can use to enhance instruction and learning at the classroom level. This teacher-centered model is of particular importance as a framework to build collective capacity by meeting psychological needs of teachers of autonomy, competence, and relatedness. 相似文献

In line with other research, Udell, Dorey, and Wynne’s (in press) finding that dogs and wolves pass on some trials of a putative
theory-of-mind test and fail on others is as informative about the methods and concepts of the research as about the subjects.
This commentary expands on these points. The intertrial differences in the target article demonstrate how critical the choice
of cues is in experimental design; the intersubject-group differences demonstrate how life histories can interact with experimental
design. Even the best-designed theory-of-mind tests have intractable logical problems. Finally, these and previous research
results call for the introduction of an intermediate stage of ability, a rudimentary theory of mind, to describe subjects’ performance. 相似文献

We introduce the Integrated Framework of Multiple Texts to understand how students use and form connections between multiple texts to accomplish personal or task goals. The Integrated Framework of Multiple Texts conceptualizes students’ multiple text use as unfolding over the course of three stages—preparation, execution, and production. In the preparation stage of the framework, individual difference factors and students’ task analysis result in learners’ adoption of a default stance, or a general orientation, toward multiple text use. During the execution stage of the framework, students engage in a variety of behavioral, cognitive, and metacognitive/regulatory strategies to develop cross-textual links and to integrate information across multiple texts. The execution stage concludes with students’ development of a variety of affective and cognitive outcomes as a consequence of text access. Finally, in the production stage of the framework, students draw on these affective and cognitive outcomes to develop external, often written products. 相似文献

The importance of being a ‘lady’: hyper‐femininity and heterosexuality in the private,single‐sex primary school 总被引:1,自引:0,他引:1
Alexandra Jane Allan 《Gender and education》2009,21(2):145-158
Drawing on recent ethnographic research in one single‐sex, private primary school, this paper will explore what it meant for the girls in this setting to embody the discourse of the ‘lady’. The paper will propose that classed and gendered discourses of respectability featured strongly in the girls’ lives, as they were expected to behave like ‘proper’ upper‐middle‐class ladies. However, the paper will also suggest that these discourses were being reworked through post‐feminist, neo‐liberal notions of modern girlhood, meaning that the girls also felt compelled to make themselves as heterofeminine ‘girly’ girls; as sassy, sexy and successful, as well as respectable and upper‐middle‐class(y) enough. By exploring the clash between these two sets of discourse, the paper will specifically seek to examine the lived embodiment of intersections of class, gender and sexuality and to explore the relevance of Judith Butler’s heterosexual matrix for these upper‐middle‐class girls. 相似文献

Previous research has demonstrated close relationships between working memory and children's scholastic attainment. The aim of the present study was to explore a method of improving working memory, using memory strategy training. Two hundred and fifty‐four children aged five to eight years were tested on measures of the phonological loop, visuo‐spatial sketchpad and central executive components of the multiple component model of working memory. Subgroups of children also completed tasks of following instructions and mental arithmetic in the classroom, and standardised tests of reading, arithmetic and mathematics. Half of the children then used Memory Booster, a computer game that teaches memory strategies, over a period of six to eight weeks. All the children were then retested on the memory and ability measures. The standardised tests were also administered five months later. The results revealed that working memory strategy training resulted in significant improvements in tasks assessing the phonological loop and central executive components of working memory, and tasks assessing following instructions and mental arithmetic in the classroom. However, no improvements were observed on standardised tests of reading, arithmetic or mathematics, either immediately following training or five months later. The results are discussed in terms of implications for educational practice. 相似文献
