The validity of two measures of English reading comprehension was examined across three different groups of English language learners (ELLs; 64 Portuguese, 66 Spanish and 65 Cantonese). All three groups were achieving within the average range in second grade. An exploratory principal components analysis of reading skills was carried out to determine which skills were related to two commonly used tests of reading comprehension, the Woodcock Language Proficiency Battery??s test of Passage Comprehension (WLPB-PC; Woodcock, 1991) and the Gray Oral Reading Test-4 (GORT-4; Wiederholt & Bryant, 2001). The factor solutions were different for the three language groups but showed many similarities in that the GORT-4 and WLPB-R tests of reading comprehension fell on the same factor within each group. Hierarchical regression analyses examining relationships among vocabulary, decoding and reading comprehension showed that language group membership did not significantly predict performance on either measure of reading comprehension. Differences that arose are likely due to issues with task validity and not ELL status. Limitations and future research are discussed.  相似文献

International studies, such as the Programme for International Student Assessment (PISA), have shown that, in most participating countries, students who do not typically speak the test language at home reach lower levels of reading comprehension than students using the test language at home (Stanat & Christensen, 2006). Results from PISA indicate that Germany is among the countries with the most pronounced differences in reading comprehension between immigrant students and students from native families. The present article summarizes these findings and shows that the reading achievement gap persists even when the socioeconomic and educational background of students?? families are controlled. Furthermore, although controlling for background factors reduces the effect of the language spoken at home on reading, it continues to be substantial. Using these findings as a starting point, the article addresses the question of what should be done to close this gap. It summarizes research findings indicating that oral proficiency presents an important determinant of reading comprehension in a second language. This suggests that effective general approaches to second-language teaching are needed to promote reading literacy in a L2. The article closes with a discussion of the available evidence on the effectiveness of such approaches and outlines the need for further research.  相似文献

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

Building on past research, this article argues that organizational life can be usefully construed as a series of communicative performances that are embedded and enacted in everyday discursive practices. Specifically, this research explores the sensemaking process individuals undertake when faced with the dilemma of knowing when to invent appropriate ways to respond rather than being automatically constrained by past routines. The research presents case study evidence drawn from participant observation and interviews with flight attendants from a major U.S. airline. Shown to be high in emotional and impression management, flight attendants perform a feminized role that privileges accommodation over authority and reassurance over safety that may influence their performances in emergency situations. The work ends with an evaluation of the dominant air travel performance in relation to safety and offers recommendations for facilitating communication and coordination among flight attendants and pilots.  相似文献

This article describes how librarians became involved as members of an interdisciplinary curricular team in a problem-based learning course for first- and second-year medical students. The experience illustrates how librarians can become part of a team, collaborating with medical faculty to assist in revising curricula, incorporating innovative teaching techniques, and creating effective simulated patient case scenarios. Working within an interdisciplinary collaborative team on curriculum development allows librarians to move beyond the traditional role of instruction and can lead to additional opportunities, including research and ongoing involvement in curricular changes.  相似文献

Scopus and Web of Science are the two major citation databases that collect and disseminate bibliometric statistics about research articles, journals, institutions, and individual authors. Liaison librarians are now regularly called upon to utilize these databases to assist faculty in finding citation activity on their published works for tenure and promotion, grant applications, and more. But questions about the accuracy, scope, and coverage of these tools deserve closer scrutiny. Discrepancies in citation capture led to a systematic study on how Scopus and Web of Science compared in a real-life situation encountered by liaisons: comparing three different disciplines at a medical school and nursing program. How many articles would each database retrieve for each faculty member using the author-searching tools provided? How many cited references for each faculty member would each tool generate? Results demonstrated troubling differences in publication and citation activity capture between Scopus and Web of Science. Implications for librarians are discussed.  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
