Perceived ability and success: which self-efficacy measures matter? A distance learning perspective     

Lerato Sonia Tladi 《Open Learning》2017,32(3):243-261

This paper sought to determine the effects of three self-efficacy measures on the academic attainment of students who were enrolled for the first time at the University of South Africa (Unisa) in 2015. The measures of interest were self-regulated learning efficacy, distance learning self-efficacy and computer and online technologies self-efficacy. Overall, only DLSE was found to have a significant effect on academic attainment albeit with a low effect (r = ?.13), explaining only 1.7% of the variation in the academic achievement between successful and unsuccessful students. DLSE also explained 10% of the variation in academic achievement between successful and unsuccessful students who, although new to Unisa, were not new to higher education.  相似文献   

Mathematical Modelling: the Interaction of Culture and Practice   总被引：1，自引：0，他引：1  

Susan Molyneux-Hodgson  Teresa Rojano  Rosamund Sutherland  Sonia Ursini 《Educational Studies in Mathematics》1999,39(1-3):167-183

Using a sociocultural approach we analyse the results of a Mexican/British project which investigated the ways in which mathematics is used in the practice of school science and the role of spreadsheets as a mathematical modelling tool. After discussing the different school cultures experienced by two groups of pre-university 16–18 year old students we analyse how these different cultures influenced their practice of mathematics, as well as their work with mathematical spreadsheet modelling activities. There were clear differences between the two groups of students in their preference for external representations, in their understanding of the kind of answers they were expected to produce and in the way they conceived the role of mathematics in the practice of science. Although students preferences for a particular representation were not significantly modified by the use of a spreadsheet as a modelling resource, at the end of the study the students recognised the value of using a more diverse set of representations. The results obtained suggest the possibility of enhancing students' capability to shift between a wider range of representations, including graphical, algebraic and numeric ones, using a modelling approach embedded in a computer environment such as a spreadsheet. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献   

Representations of sibling relationships in young children’s literature     

Laurie Kramer  Sonia Noorman  Renee Brockman 《Early childhood research quarterly》1999,14(4):555

Children’s conceptions of what sibling relationships can be like may be influenced, in part, by the literature they read. This study examined the degree to which positive and negative dimensions of sibling relationships were portrayed in a sample of children’s books (n = 261). We also investigated how mothers and fathers were depicted when responding to sibling conflict. Results indicated that although children’s books often represent warmth and involvement between siblings, they rarely described children engaging in conflict management or relational maintenance activities. Parents were predominantly portrayed as responding to children’s conflict using controlling methods rather than techniques that might foster negotiation and problem solving. Characters who were middle children are under-represented in children’s literature. Results are discussed in terms of how educators can select, use, and adapt books in their efforts to help strengthen children’s sibling relationships.  相似文献   

An Example of the Informative Potential of Polar Coordinate Analysis: Sprint Tactics in Elite 1,500-m Track Events     

Sonia Aragón  Javier Arana  M. Teresa Anguera  Belén Garzón 《Measurement in physical education and exercise science》2017,21(1):26-33

Polar coordinate analysis is a powerful data reduction technique based on the Zsum statistic, which is calculated from adjusted residuals obtained by lag sequential analysis. Its use has been greatly simplified since the addition of a module in the free software program HOISAN for performing the necessary computations and producing easy-to-interpret results in the form of polar coordinate maps. In this study, we provide a simple and practical example of how this technique can be used to analyze tactical behaviors in sport and physical exercise. We studied 158 performances by 82 male runners in thirteen 1,500-m finals held at the Olympic Games, the World Championships in Athletics, and the European Athletics Championships between 2000 and 2012 to investigate associations between the initiation of sprints by race winners and other runners (focal behaviors) and the lap and zone of the track in which the sprints were initiated (conditional behaviors). The significant prospective/retrospective activating/inhibitory relationships shown in the polar coordinate maps confirm the decision to start a sprint is a tactical one and are consistent with a winning strategy consisting of avoiding giving rivals the benefit of the slipstream while conserving sufficient energy for a final winning burst. Polar coordinate analysis is a powerful technique for studying tactical behaviors in the field of sport.  相似文献

“Sharenting,” parent blogging,and the boundaries of the digital self     

Alicia Blum-Ross  Sonia Livingstone 《Popular Communication》2017,15(2):110-125

ABSTRACT

This article asks whether “sharenting” (sharing representations of one’s parenting or children online) is a form of digital self-representation. Drawing on interviews with 17 parent bloggers, we explore how parents define the borders of their digital selves and justify what is their “story to tell.” We find that bloggers grapple with profound ethical dilemmas, as representing their identities as parents inevitably makes public aspects of their children’s lives, introducing risks that they are, paradoxically, responsible for safeguarding against. Parents thus evaluate what to share by juggling multiple obligations—to themselves, their children in the present and imagined into the future, and to their physical and virtual communities. The digital practices of representing the relational self are impeded more than eased by the individualistic notion of identity instantiated by digital platforms, thereby intensifying the ambivalence of both parents and the wider society in judging emerging genres of blogging the self.  相似文献   

Promoting Gypsy children's behavioural engagement and school success: Evidence from a four‐wave longitudinal study          下载免费PDF全文

Pedro Rosário  José Carlos Núñez  Guillermo Vallejo  Raquel Azevedo  Raquel Pereira  Tânia Moreira  Sonia Fuentes  Antonio Valle 《British Educational Research Journal》2017,43(3):554-571

Low schooling, high non‐attendance and school dropout rates are critical phenomena within disadvantaged groups, especially among the Gypsy community. For example, in the UK, 10%–25% of Gypsy children do not attend school regularly and have significantly higher levels of overall absence from school (percentage of half‐day sessions missed) than pupils from other ethnic groups. In Portugal, available data on Gypsy children is sparse, yet data from one geographic region of the country reports high school failure (45%) and dropout rates (15%) among this population. The present study assessed the efficacy of a four‐year intervention to promote Gypsy children's behavioural engagement and school success. Gypsy communities were contacted and 30 children participating in the four waves were randomly distributed into control and experimental groups. Every school day throughout four years, 16 children in the experimental group were called at home and invited to go to school. The effectiveness of the intervention was evaluated in four waves (at the end of each of the four school years), assessing behavioural engagement (i.e. school non‐attendance, classroom behaviour) and school achievement (i.e. mathematics achievement, student progression). Findings show the efficacy of the intervention on promoting behaviour engagement and academic success without devaluing Gypsy people's culture.  相似文献   

A Framework for User Agency during Development of Interactive Risk Visualization Tools     

Sonia H. Stephens  Denise E. DeLorme 《Technical Communication Quarterly》2013,22(4):391-406

ABSTRACT

Participating in user-centered design provides potential users of interactive risk visualization tools agency in influencing tool development. This article identifies and characterizes pathways for agency that users may experience as they participate in design of interactive tools for visualizing environmental risks. We present an empirically based conceptual framework for better understanding user agency during visualization tool development based on findings from interviews with professional visualization tool developers and discuss practical implications and future research recommendations.  相似文献   

Publishing in Discipline-Specific Non-Library Journals for Promoting Information Literacy     

Robert Tomaszewski  Karen I. MacDonald  Sonia Poulin 《The Journal of Academic Librarianship》2013

Academic librarians tend to publish in traditional “library” journals rather than journals directed at other academic disciplines, thereby missing the opportunity to inform and educate a key audience. This article alerts librarians to publishing opportunities in discipline-specific academic journals in the Arts & Humanities, Sciences, and Social Sciences, both as a means of promoting information literacy (IL) and effecting outreach to faculty. Selection criteria are defined and discussed. The results of the study are presented by discipline in table format with data on each journal including publisher, affiliation, publication frequency, review time, acceptance rate, and ranking indicators.  相似文献   

Audiences for crime media 1946–91: A historical approach to reception studies     

Sonia Livingstone  Jessica Allen  Robert Reiner 《The Communication Review》2013,16(2):165-192

The present paper argues that audience reception studies have tended to be ahistorical, neglecting consideration of the ways in which audiences’ orientation to media may have changed over the decades. The paper explores the potential of combining oral history methods with reception studies, and addresses some of the difficulties which arise. An apparently simple way to introduce a historical perspective is attempted by including audience age as a central part of an empirical research design. By analysing a series of focus group discussions in which people respond to crime media from different points over the postwar period, the concept of age is unpacked in terms of generation and life course factors, and these are shown to influence reception of crime media from both the present and the past. Generation and life course, together with gender, also affect people's positioning in society in relation to real‐world crime, and this too affects the reception of crime media. The paper concludes by suggesting three ways in which audiences may have changed over the postwar period in terms of their interpretive frames for making sense of crime media, namely the frames of personal relevance, realism and moral relativism.  相似文献
