While some online newspapers have embellished their online presence with a variety of interactive features, most online newspapers still appear to take on the role of cautious traditionalists, adopting a mostly conservative stance toward the new medium. Correspondingly, most audience members appear to act in a similar way. This article shows how concepts related to structuration theory can be utilized to further our theoretical understanding of the use (and nonuse) of interactive features in the online newspaper context. It employs concepts from the structuration theory to provide another interpretation of the existing empirical research. The paper concludes by suggesting that “nonuse” in this regard can be understood as part of reproducing what might be called a “structure of audiencehood” rather than a “structure of prosumerism.”  相似文献

ABSTRACT

Background: Research on physical education (PE) shows a prevalence of narrow and reductionist views on what counts as ability. These views tend to privilege certain students and marginalize others, and often equate ability with technique-based sport performance. A lot of research is still directed towards the above problem. However, very few have devoted time and energy to actually resolving this problem. If no alternatives to narrow and reductionist views of ability are presented, then research will struggle to make a difference to the practice of PE. Assuming that movement is a key element in PE, the question of what counts as ability in PE is, we argue, a question of what capabilities a learner needs to develop in order to move in different ways. Investigating what movement capability can mean will provide possibilities for discussing and negotiating the meaning of ability in PE when the learning goal is something other than technique-based sport performance.

Purpose: The aim of this paper is to further advance the knowledge base of what movement capability can mean within the context of PE. By achieving this aim, we intend to challenge narrow views on ability and thereby provide enhanced possibilities for PE to make a difference for students’ abilities through education.

Theory and method: The process of coming to know something can be seen as exploring, with all senses, a landscape. Exploration involves recognizing details and nuances of the landscape and their relationships to one another. In this investigation, we examine what there is to know in the landscape of juggling using Ryle’s and Polanyi’s notions of knowing and learning. In line with a focus on the learners’ perspectives, interviews and observations were conducted with students whilst they were coming to know juggling. Ethnographic-type conversations were used to help students describe what they seemed to know or were aiming to know. Students were invited to write diaries with a focus on their experiences during the learning process, which we hoped could extend our insights regarding the experiential aspects in learning.

Findings: Findings of the investigation suggest that in the group of students, four significant ways of knowing the landscape of juggling are important: grasping a pattern; grasping a rhythm; preparing for the next throw and catch and navigating one’s position and throwing. The research challenges the narrow view on ability as technique-based sport performance by providing examples of what movement capability can mean in terms of knowing a movement landscape alternatively to knowing a specific movement ‘in the right way.’  相似文献

Two experiments are reported that investigated the relative effectiveness of a realistic dynamic visualization as opposed to a schematic visualization for learning about cell replication (mitosis). In Experiment 1, 37 university students watched either realistic or schematic visualizations. Students' subjective task demands ratings as well as their performance in a multiple-choice test and a pictorial test clearly demonstrated the superiority of the schematic dynamic visualization. In Experiment 2, 83 students were given the two visualizations in four different orders of presentation. Students showed the same performance irrespective of whether they watched the schematic visualization twice, first saw the schematic and then the realistic visualization or vice versa. Only students, who watched the realistic visualization twice, had far lower learning outcomes. Contrary to our expectations, for both experiments, students' prior knowledge did not moderate the results.  相似文献

We employ finely geo-coded firm-level panel data to assess the long-standing question whether agglomeration economies derive from specialization (within-industry), diversity (between-industry) or overall density. Rather than treating the city as a single unit, we focus our analysis on how the inner industry structures of cities influence firm-level productivity. Our results illustrate the co-existence of several externalities that differ in their spatial distribution and attenuation within cities. First, we find robust positive effects of neighborhood-level specialization on TFP as well as a small effect of diversity at the same fine spatial level. These effects are highly localized and dissipate beyond the immediate within-city neighborhood level. Second, we also find that firms benefit from the overall density of the wider city. The results emphasize the relevance of “opening up” cities to study the workings of their inner organization and support the idea that location in a within-city industry cluster in a diversified and dense city boosts productivity.  相似文献

Within caring science, the concept of caring leadership is well established. The aim of this study is to introduce Bondas’s theory of caritative leadership into education. The theory of caritative leadership is a theory of caring leadership with the ‘caritas’ thought of human love and mercy at its core. The article considers a hypothetical testing of the transferability of a nursing leadership theory, with its roots in caring science, into the field of education. The material consists of about 90 sources from the disciplines of nursing, education, management, and psychology. A caritative leadership would support Bildung – a comprehensive view of the edification of life, personal growth and maturity – as an ultimate goal of education. In the emerging model of a caritative leadership in education, a humanistic ethos of love, trust, and forgiveness shapes the culture of the educational organisation. The pedagogical leader supports the process of human becoming by implementing the idea of human beings as vulnerable, moral, dignified and unique individuals. The leader develops an ability to know which objectives to measure and which experiences of others to learn from, while performing such tasks as planning, reporting and directing in accordance with the mission of the organisation.  相似文献

Background: Models-based approaches to physical education have in recent years developed as a way for teachers and students to concentrate on a manageable number of learning objectives, and align pedagogical approaches with learning subject matter and context. This paper draws on Hannah Arendt’s account of vita activa to map existing approaches to physical education as oriented towards: (a) health and exercise, (b) sport and games, and (c) experience and exploration.

Purpose: The aim of the paper is to outline a new pedagogical model for physical education: a practising model. We argue that the form of human activity related to practising is not well represented in existing orientations and models. To sustain this argument, we highlight the most central aspects of practising, and at the same time describe central features of the model.

Relevance and implications: The paper addresses pedagogical implications the practising model has for physical education teachers. Central learning outcomes and teaching strategies related to four essential and ‘non-negotiable’ features of the practising model are discussed. These strategies are: (1) acknowledging subjectivity and providing meaningful challenges, (2) focusing on content and the aims of practising, (3) specifying and negotiating standards of excellence and (4) providing adequate time to practising.

Conclusion: The practising model has the potential to inform new perspectives on pedagogical approaches, and renew and improve working methods and learning practices, in physical education.  相似文献

Anterior cruciate ligament (ACL) injuries commonly occur during jump-landing tasks when individuals’ attention is simultaneously allocated to other objects and tasks. The purpose of the current study was to investigate the effect of allocation of attention imposed by a secondary cognitive task on landing mechanics and jump performance. Thirty-eight recreational athletes performed a jump-landing task in three conditions: no counting, counting backward by 1 s from a randomly given number, and counting backward by 7 s from a randomly given number. Three-dimensional kinematics and ground reaction forces were collected and analysed. Participants demonstrated decreased knee flexion angles at initial contact (p = 0.001) for the counting by 1 s condition compared with the no counting condition. Participants also showed increased peak posterior and vertical ground reaction forces during the first 100 ms of landing (p ≤ 0.023) and decreased jump height (p < 0.001) for the counting by 1 s and counting by 7 s conditions compared with the no counting condition. Imposition of a simultaneous cognitive challenge resulted in landing mechanics associated with increased ACL loading and decreased jump performance. ACL injury risk screening protocols and injury prevention programmes may incorporate cognitive tasks into jump-landing tasks to better simulate sports environments.  相似文献

Studies of African indigenous games often focus on a specific game or on games from different regions. This article, rather, examines five popular African board games in order to find the similarities and differences among these games. The analysis shows similarities among them. However, these similarities do not necessarily mean that these games are identical. The review of the games indicates that these games are different when elements such as rules and play are used to study them. This article also demonstrates that these board games are tools that can be integrated into the curriculum through a discussion of the educational affordance of each game. The article is an invitation to educators and game researchers to broaden the definition and exploration of game-based learning.  相似文献

Research shows that Looked After Children (LAC) may experience emotional instability which can reduce their capacity to engage with education. This study evaluates an attachment based therapeutic Theraplay® intervention designed to bridge the gap between the emotional well-being of LAC and their engagement in education. Twenty LAC between the ages of five to 11 from nine schools participated in the project over eight months. The mixed method study used a repeated measures design. Strengths and difficulties questionnaires were used pre- and post-intervention; semi-structured interviews with teaching staff were conducted and children’s views were gathered. Quantitative results show a reduction in the children’s total strengths and difficulties stress scores post-intervention. Qualitative feedback shows noticeable changes in the children’s relationship skills, confidence and engagement with education. The complexities of supporting LAC in education and implications for educational psychology practice are explored.  相似文献
