The way children's cognitive states affect how they function in digital interfaces is examined through articles published between 1989 and 2010. Children have developmental limitations, such as underdeveloped motor skills, difficulties with spelling, and trouble understanding hierarchies, classification schemes, and metadata, that make it difficult for them to find information, and challenging for adult designers to accommodate their needs. From icons to metadata to hierarchies, the best research in designing digital resources for children, (OPACs such as Pejtersen's Book House, online public libraries such as the Internet Public Library, and online collections of books such as the International Children's Digital Library), places the child user at the center, and takes an interdisciplinary and intergenerational approach. The literature indicates that research in designing for children is valuable, not only because it seeks to improve children's experience with digital resources, but also because such research translates to other marginalized users and special needs populations. 相似文献

In the present study, associations between executive functioning, metacognition, and self-perceived competence in the context of early academic outcomes were examined. A total of 209 children attending first grade were initially assessed in terms of their executive functioning and academic self-concept. One year later, children??s executive functioning, academic self-concept, metacognitive monitoring and control, as well as their achievement in mathematics and literacy were evaluated. Structural equation modeling revealed that executive functioning was significantly related to metacognitive control, both cross-sectionally and longitudinally, and that self-concept was substantially associated with metacognitive monitoring, both cross-sectionally and longitudinally. Individual differences in executive functioning and metacognitive control were significantly related to academic outcomes, with metacognitive control appearing to yield a more circumscribed influence on academic outcomes (only literacy) compared to executive functioning (literacy and mathematics). 相似文献

This paper presents a conceptual analysis for students’ images of graphs and their extension to graphs of two-variable functions. We use the conceptual analysis, based on quantitative and covariational reasoning, to construct a hypothetical learning trajectory (HLT) for how students might generalize their understanding of graphs of one-variable functions to graphs of two-variable functions. To evaluate the viability of this learning trajectory, we use data from two teaching experiments based on tasks intended to support development of the schemes in the HLT. We focus on the schemes that two students developed in these teaching experiments and discuss their relationship to the original HLT. We close by considering the role of covariational reasoning in generalization, consider other ways in which students might come to conceptualize graphs of two-variable functions, and discuss implications for instruction. 相似文献

In this article, we explore the reality of Icelandic preschool teachers who are, as in most other countries, predominantly female. The gendered nature of the role and the current identity adopted by preschool teachers appear to impact on their perceived status and professionalism. In this process, stakeholders in early childhood education (ECE), as well as the preschool teachers themselves, play important parts. The question that underlies the paper is: ‘How do the views of preschool teachers and stakeholders in ECE affect the preschool teachers’ professional identity?’ The data used to answer the question are from focus group research carried out with preschool teachers and stakeholders in ECE in one community in Iceland. These stakeholders, besides preschool teachers and staff within the preschools, were parents, professionals at the municipal preschool office and politicians. The theoretical perspective informing the methodology of the research was ‘symbolic interactionism’ and the concept of ‘democratic professionalism’ was used as an aspirational framework to analyse the data. The findings reveal connections between the ideology relating to the preschool teachers’ educational role, their limited leadership and the gendered views of stakeholders. At the end of the paper, implications and recommendations for preschool teachers are suggested. 相似文献

This paper examines the use of student planners (agendas) with elementary school students. It asks how teachers, students and parents in two classrooms engage in the literacy practice of using student planners. A literacy object originally introduced to manage schoolwork in and out of school for students with learning difficulties, planners are now used widely in school districts across North America. In this cross‐case analysis, planners are shown to be used for a number of functions beyond organising students’ schoolwork. The student planners were tools through which teachers, parents and publishers extended their spheres of influence – objects used to manage others when an individual was not physically present to do so and objects used to gain entry to the classrooms and homes for particular purposes. 相似文献

ABSTRACTVenture capital funding is an increasingly common yet understudied management model in the rapidly changing market of news media. Drawing on scholarship in media management and entrepreneurship, this study applies a community ecology framework to analyze the relationship between venture capital funding and digital news media firms. In doing so, this work explores the interaction between legacy news media firms and new entrants as they struggle for scarce resources and seek to grow in the face of rapid change. A dataset tracking funding activity of legacy and startup news media firms is used to analyze resource allocation within the digital news media ecosystem. Results of the analyses provide insights for news media management by furthering understanding regarding venture capital funding models and the generative mechanisms that help drive growth. Specifically, findings highlight the importance of cross-sector engagement and the tension between firm age and position for growth in the digital news media ecosystem. 相似文献

The purpose of this study was to examine the relationships between college students’ level of driver anger and their aggressive communication traits. Driving anger is an individual's tendency to become angry while driving. In 1994 the driving anger scale (DAS) identified six dimensions of driver anger: hostile gestures, illegal driving, police presence, slow driving, discourtesy, and traffic obstructions. Results of Pearson correlations show that police presence, slow driving, discourteous driving, and traffic obstructions were positively related to all of the aggressive communication traits. “Hostile gestures” was related to assertiveness. Illegal driving was related to indirect verbal aggression and assertiveness. 相似文献
