P van den Broek 《Child development》1989,60(2):286-297

The present study investigated the development of the ability to judge the importance of story statements on the basis of their causal properties. Key statements were varied with respect to 2 factors: in terms of the number of their causal relations, and in terms of the kinds of relations they had. Relations were either intraepisodic, that is, connecting statements in the same episode, or interepisodic, that is, connecting statements in different episodes. Children 8, 11, 14, and 18 years of age judged the importance of the statements. Children in all 4 age groups judged statements with many intraepisodic causal relations as more important than statements with few such relations. Only children 11 years and older judged statements as more important when they had interepisodic relations than when they did not. Thus, although young children may be sensitive to quantitative aspects of a statement's relational role within an episode, they may not be as aware of qualitative, that is, structural, differences between kinds of relations. Answers to why questions confirmed these patterns. Older children more often gave answers that crossed episodic boundaries than did the younger children. These findings may reflect age-related differences in children's ability to infer relations between statements and to integrate the information contained in stories. They also attest to the central role that causal inferences play in the interpretation of what is important information in stories.  相似文献   

Measures of reading comprehension: do they measure different skills for children learning English as a second language?     

Amy Grant  Alexandra Gottardo  Esther Geva 《Reading and writing》2012,25(8):1899-1928

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   

Reading comprehension of immigrant students in Germany: research evidence on determinants and target points for intervention     

Alexandra E. Marx  Petra Stanat 《Reading and writing》2012,25(8):1929-1945

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   

Rethinking library service to distance education students: analyzing the embedded librarian model     

Sullo E  Harrod T  Butera G  Gomes A 《Medical reference services quarterly》2012,31(1):25-33

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   

Selection committee membership: Service or self-service     

Peter van den Besselaar 《Journal of Informetrics》2012,6(4):580-585

Project funding is an increasingly important mode of research funding. The rationale is that through project funding new fields and new themes can be supported more effectively. Furthermore, project funding improves competition, which is expected to select the better research projects and researchers. However, project funding has a price, as it requires researchers to invest time in reviewing proposals, and to participate in selection committees. In that perspective, selection committee membership can be seen as a service to the scholarly community.However, what do committee members themselves get from membership? In this paper we show that committee members in average are more successful in grant applications than other principle investigators, and this is not explained by performance differences. The findings suggest that committee membership is not only service, but also self-service.  相似文献

First-graders’ knowledge of multiplicative reasoning before formal instruction in this domain     

Marjoke Bakker  Marja van den Heuvel-Panhuizen  Alexander Robitzsch 《Contemporary educational psychology》2014

Our study investigated children’s knowledge of multiplicative reasoning (multiplication and division) at the end of Grade 1, just before the start of formal instruction on multiplicative reasoning in Grade 2. A large sample of children (N = 1176) was assessed in a relatively formal test setting, using an online test with 28 multiplicative problems of different types. On average, the children correctly answered more than half (58%) of the problems, including several bare number problems. This indicates that before formal instruction on multiplicative reasoning, children already have a considerable amount of knowledge in this domain, which teachers can build on when teaching them formal multiplication and division. Using analysis of variance and cross-classified multilevel regression analysis, we identified several predictors of children’s pre-instructional multiplicative knowledge. With respect to the characteristics of the multiplicative problems, we found that the problems were easiest to solve when they included a picture involving countable objects, and when the multiplicative situation was of the equal groups semantic structure (e.g., 3 boxes of 4 cookies). Regarding student characteristics, pre-instructional multiplicative knowledge was higher for children with higher-educated parents. Finally, the mathematics textbook used in school appeared to have influenced children’s pre-instructional multiplicative knowledge.  相似文献

The flight attendant dilemma: an analysis of communication and sensemaking during in-flight emergencies     

Alexandra Murphy 《Journal of Applied Communication Research》2013,41(1):30-53

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   

Expanding Our Roles: Embedded in Curriculum Design     

Gisela Butera  Alexandra W. Gomes  Seema Kakar 《Medical reference services quarterly》2013,32(3):292-301

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
