Previous research has suggested that handwriting letters may be an important exerciser to facilitate early letter understanding. Experimental studies to date, however, have not investigated whether this effect is general to any visual–motor experience or specific to handwriting letters. In the present work, we addressed this issue by testing letter knowledge using three measures in preschool children before and after a school-based intervention. Participants were divided into four training groups (letter-writing, digit-writing, letter-viewing, digit-viewing) that either wrote letters or digits or viewed letters or digits, twice a week for 6 weeks. We hypothesized that the visual–motor experience of handwriting letters or digits would improve letter knowledge more than viewing experience and that this effect would not be specific to training with letters. Our results demonstrated that the writing groups improved in letter recognition—one component of letter knowledge—significantly more than the viewing groups. The letter-writing group did not improve significantly more than the digit-writing group. These results suggest that visual–motor practice with any symbol could lead to increases in letter recognition. We interpret this novel finding as suggesting that any handwriting will increase letter recognition in part because it facilitates gains in visual–motor coordination.  相似文献

The purpose of this article is to investigate in situ the functions that knowledge has when used by students in argumentative discussions. The study is based on Dewey’s pragmatic perspective of knowledge, which means that knowledge gets its meaning in the activity at hand. The analyses are conducted using Transactional Argumentation Analysis, which is a combination of pragmatic meaning analysis and Toulmin’s argument pattern. The empirical material consists of video-recorded lessons from two seminars in a Swedish upper secondary school. The results show that knowledge plays a crucial role in the discussions. Six different functions are identified: emphasising complexity, clarifying and correcting, highlighting conflicting interests, providing evidence in a counterargument, predicting the consequences and adding support to an earlier claim. Knowledge also has general functions, such as justifying a claim, and is part of a collective process aimed at understanding the issues discussed. Further, the students use knowledge from different disciplines, such as environmental studies, history, politics, biology and human geography.  相似文献

Drawings are often used to obtain an idea of children's conceptions. Doing so takes for granted an unambiguous relation between conceptions and their representations in drawings. This study was undertaken to gain knowledge of the relation between children's conceptions and their representation of these conceptions in drawings. A theory of contextualization was the basis for finding out how children related their contextualization of conceptions in conceptual frameworks to their contextualization of drawings in pictorial convention. Eighteen children were interviewed in a semi‐structured method while they were drawing the Earth. Audio‐recorded interviews, drawings, and notes were analysed to find the cognitive and cultural intentions behind the drawings. Also, even children who demonstrated alternative conceptions of the Earth in the interviews still followed cultural conventions in their drawings. Thus, these alternative conceptions could not be deduced from the drawings. The results indicate that children's drawings can be used to grasp children's conceptions only by considering the meaning the children themselves give to their own drawings.  相似文献

This paper applies a sociology of childhood approach to the study of the sexual socialisation of young children in the USA. It examines both children's and parents' active participation in this dynamic and collaborative process through conversations between 49 parents and their 54 preschool children that were audio-recorded while they read books about ‘where babies come from’. Parents also participated in a brief survey. The authors found that, while parents do foreclose such conversations as previous research has indicated, they also use a variety of other tactics, including adding information and emotion management. These findings illustrate children's active engagement in their own sexual socialisation through their questions, confusions and distractions, which affected the amount and type of information that was elicited.  相似文献

In the past few decades, increasing attention has been devoted within various disciplines to aspects previously considered trivial, among which are images, material objects and spaces. While the visual, the material and the spatial are receiving ever more consideration and the myriad issues surrounding them are being tackled, their convergence in educational settings across time and space has thus far remained underexplored. A travelling photo exhibition, The Family of Man, will serve as a starting point in this paper for addressing some of the complexities inherent in this convergence and thus highlight an essential yet neglected feature of education: its reliance on, and creative use of, multiple “modes” of communication and representation when attempting to produce learning effects. As a particular educational constellation that went on to travel throughout the world and interact with the contexts in which it moved, The Family of Man was anything but neutral in design. The paper will show just how carefully it was composed to promote meaning-, power-, and knowledge-making in accordance with its mission. This border-crossing installation thus constituted a spectacle of different interacting views, forms, surfaces, lighting effects, panoramas, movements, captions and other factors that aimed to create order among things and people. Nevertheless, the paper argues, “theatres of display” in education such as this do not imply determination and causality of effects, but rather provide “uncertain conditions” within a spectrum of “actors” and “actants”. The paper relates this to the manifold affordances of objects, images, places and so on, to disruptions of meaning in their convergence across time and space and to “emancipation” on the part of learners.  相似文献

Abstract

This article presents examples of metadata collaborations between the Swiss National Library (NL) and research institutions in the field of Swiss historiography. The NL publishes the Bibliography on Swiss History (BSH). In order to meet the demands of its research community, the NL has improved the accessibility and interoperability of the BSH database. Moreover, the BSH takes part in metadata projects such as Metagrid, a web service linking different historical databases. Other metadata collaborations with partners in the historical field such as the Law Sources Foundation (LSF) will position the BSH as an indispensable literature hub for publications on Swiss history.  相似文献

In this study we focus on the film The Siege (1998), as an illustration of how mediated representations of terrorism serve as a vehicle for Orientalist discourse. This text serves as a specific location of struggle and negotiation over interpretations of media characterizations of Arabs, Arab Americans, Muslims, and Islam. First, we focus on how the film represents these communities and the religion textually. Second, we consider news discourse offering critiques of the film by protesting organizations, and the defenses articulated by some of the film's makers. Third, we explore the interpretations of young U.S. viewers as they resonate with competing facets of the text and with public perspectives. Despite the varied possibilities within the text, these interpretations privileged rather than challenged an underlying Orientalist ideology. Still, news media did acknowledge the contestation of dominant discourse, a potential step toward improved portrayals.  相似文献

The authors used realistic evaluation to examine the real-world effectiveness of two 5-day training techniques on sustained optimal skin-to-skin practices that support Step 4 of the revised Baby-Friendly Hospital Initiative (BFHI). The authors found that education alone was insufficient to effect sustainable practice change. Exposure to the 5-day immersion model (Practice, Reflection, Education and training, Combined with Ethnography for Sustainable Success, or PRECESS) alone or combined with education was an effective strategy to change and sustain the standard of care for skin-to-skin practice (p < 0.00001). The intended outcome of sustained practice change toward implementation of skin-to-skin care through immersion or a combined approach shows promise and should be repeated in other localities.  相似文献
