Discontinuity of Reference Hinders Children's Learning of New Words     

Jessica F. Schwab  Casey Lew-Williams 《Child development》2020,91(1):e29-e41

When referring to objects, adults package words, sentences, and gestures in ways that shape children's learning. Here, to understand how continuity of reference shapes word learning, an adult taught new words to 4-year-old children (N = 120) using either clusters of references to the same object or no sequential references to each object. In three experiments, the adult used a combination of labels and other object references, which provided informative discourse (e.g., This is small and green), neutral discourse (e.g., This is really great), or no verbal discourse. Switching verbal references from one object to another interfered with learning relative to providing clustered references to a particular object, revealing that discontinuity in discourse hinders children's encoding of new words.  相似文献   

This car seems to be alive – perspectives on the documentary, Plan F     

Margaret M. Quinlan  J. Webster Smith  Casey Hayward 《Journal of Research in Special Educational Needs》2009,9(1):59-61

Ed Marko redefines what it means to be not only an auto mechanic but also a person who is blind. At the age of 20 years, he lost his sight from a degenerative disease called infantile glaucoma. However, he has surpassed what we traditionally think of as the capabilities of blind people. Now in his late 60s, he was once a rehabilitation counsellor, but he also enjoyed working on cars. Then he decided to open his own shop, Community Car Care, in Columbus, Ohio. Plan F , a 27-minute documentary awarded the 2007 Oxford International Film Festival Award in cinematography and nominated for best short documentary at the Southern Winds Film Festival, takes us through a day in Ed's life as we watch him work on cars and interact with his partner Brad and his cat. Ed teaches us that one does not need to see to work on cars as he uses his fingers and tongue to manipulate bolts, nuts and bearings. The ways Ed navigates the auto shop demonstrate how he approaches life. If Plan A does not work, he moves on to Plan B. Flexibility and a sense of humour allow him to switch to a new plan when the first one does not work out. In this review of Plan F , we begin with summaries of the nine major scenes of the documentary, followed by reviews by a blind and a sighted person. The piece concludes with comments from the director.  相似文献   

Student trajectories in physics: the need for analysis through a socio-cultural lens     

Mara Zapata 《Cultural Studies of Science Education》2010,5(3):729-734

An analysis of student connections through time and space relative to the core discipline of physics is attempted, as viewed through the lens of actor-network-theory, by Antonia Candela. Using lenses of cultural realities, networks, and perceived power in the discourse of one specific university in the capital city of Mexico and one undergraduate physics classroom, the trajectories and itineraries of students are analyzed, relative to a physics professor’s pedagogical practices. This ethnographic study then yields comparisons between Mexican undergraduate students and students from the United States. Actor network theory recognizes that the symbiotic relationship existing between an actor and a continuum of space and time is defined by the symbiotic yet interdependent relationships and networks of practice (Lemke in Downward causation: Minds, bodies, and matter 2000). As part of this study and in line with actor-network-theory, human actors and non-human participants were viewed in relation to how subjects acted and were acted upon within networks of practice. Through this forum I reflect on this work with particular focus on the issues of situatedness of actors from a sociocultural perspective and how established networks viewed within this perspective frame and subsequently impact student trajectories and itineraries. In essence I argue for a need to look at a myriad of further complexities driving the symbiotic relationships being analyzed.  相似文献   

Equivalence of Population Variances: Synchronizing the Objective and Analysis     

Constance A. Mara 《Journal of Experimental Education》2018,86(3):442-457

Researchers are often interested in establishing equivalence of population variances. Traditional difference-based procedures are appropriate to answer questions about differences in some statistic (e.g., variances, etc.). However, if a researcher is interested in evaluating the equivalence of population variances, it is more appropriate to use a procedure designed to determine equivalence. A simulation study was used to compare novel equivalence-based tests to traditional variance homogeneity tests under common data conditions. Results demonstrated that traditional difference-based tests assess equality of variances from the wrong perspective and that the proposed Levene-Wellek-Welch test for equivalence of group variances the best performing test for detecting equivalence. An R function is provided in order to facilitate use of this test for equivalence of population variances.  相似文献   

Sport studies     

Casey Mainsbridge  Karen Swabey  Dean Cooley 《Sport, Education and Society》2013,18(3):388-390

The sport-for-development movement has grown exponentially in the last decade generating increasing academic attention. However, existing research has rarely sought the views of young people despite them being both the main target audience of initiatives and frequently the deliverers. This paper seeks to address young people's absence within research and advocate the importance of engaging them in sport-for-development debates to enhance understanding of current delivery and to improve policy and practice in the future. The paper examines Zambian young people's views of HIV/AIDS peer-led education delivered through sport considering particularly whether young people believe such interventions can encourage empowerment and subsequent behaviour change. The paper outlines the importance of improving understanding of how young people can begin to translate knowledge into agency. The paper concludes with the suggestion that change is more likely if peer-led education through sport programmes are combined with multi-layered interventions directed at all levels of communities.  相似文献   

‘The right path of equality’: supporting high school students with autism who type to communicate     

Casey Woodfield  Christine Ashby 《International Journal of Inclusive Education》2016,20(4):435-454

The inclusion of students who type to communicate has been researched and strategies to accommodate such students have been recommended, but little information has been gathered about the students’ perspectives and daily school lives. This study utilises classroom observations and qualitative interviewing to explore the experiences of three high school students who type to communicate and the systems in place to support them. The study privileges and focuses on the ways that their school personnel honour the voices of those students as contributors to the construction of the spaces they enter and ways in which their active participation is supported.  相似文献   

Peer victimization, poor academic achievement, and the link between childhood externalizing and internalizing problems     

van Lier PA  Vitaro F  Barker ED  Brendgen M  Tremblay RE  Boivin M 《Child development》2012,83(5):1775-1788

This study explored whether early elementary school aged children’s externalizing problems impede academic functioning and foster negative social experiences such as peer victimization, thereby making these children vulnerable for developing internalizing problems and possibly increasing their externalizing problems. It also explored whether early internalizing problems contributed to an increase in externalizing problems. The study examined 1,558 Canadian children from ages 6 to 8 years. Externalizing and internalizing problems, peer victimization, and school achievement were assessed annually. Externalizing problems lead to academic underachievement and experiences of peer victimization. Academic underachievement and peer victimization, in turn, predicted increases in internalizing problems and in externalizing problems. These pathways applied equally to boys and girls. No links from internalizing to externalizing problems were found.  相似文献   

The Roots of Stereotype Threat: When Automatic Associations Disrupt Girls' Math Performance     

Silvia Galdi  Mara Cadinu  Carlo Tomasetto 《Child development》2014,85(1):250-263

Although stereotype awareness is a prerequisite for stereotype threat effects (Steele & Aronson, 1995), research showed girls' deficit under stereotype threat before the emergence of math–gender stereotype awareness, and in the absence of stereotype endorsement. In a study including 240 six‐year‐old children, this paradox was addressed by testing whether automatic associations trigger stereotype threat in young girls. Whereas no indicators were found that children endorsed the math–gender stereotype, girls, but not boys, showed automatic associations consistent with the stereotype. Moreover, results showed that girls' automatic associations varied as a function of a manipulation regarding the stereotype content. Importantly, girls' math performance decreased in a stereotype‐consistent, relative to a stereotype‐inconsistent, condition and automatic associations mediated the relation between stereotype threat and performance.  相似文献

Automatically Batch Loading Metadata from MARC into a Work-Based Metadata Model for Music     

Jenn Riley  Casey Mullin  Caitlin Hunter 《Cataloging & classification quarterly》2013,51(6):519-543

This article describes work done at Indiana University to “batch load” data from MARC bibliographic and authority records into the Work-based and FRBR-like Variations system. A series of experiments to iteratively refine our batch loading algorithm is described, along with details of how the algorithm identifies Works, creates relationships between entities, and maps a large amount of data from MARC into Variations records. The article closes with a discussion of the potential impact of this work on Variations project workflow and community FRBRization activities.  相似文献
