The purpose of this study was to document how teachers and students describe and comprehend the ways in which participating in an augmented reality (AR) simulation aids or hinders teaching and learning. Like the multi-user virtual environment (MUVE) interface that underlies Internet games, AR is a good medium for immersive collaborative simulation, but has different strengths and limitations than MUVEs. Within a design-based research project, the researchers conducted multiple qualitative case studies across two middle schools (6th and 7th grade) and one high school (10th grade) in the northeastern United States to document the affordances and limitations of AR simulations from the student and teacher perspective. The researchers collected data through formal and informal interviews, direct observations, web site posts, and site documents. Teachers and students reported that the technology-mediated narrative and the interactive, situated, collaborative problem solving affordances of the AR simulation were highly engaging, especially among students who had previously presented behavioral and academic challenges for the teachers. However, while the AR simulation provided potentially transformative added value, it simultaneously presented unique technological, managerial, and cognitive challenges to teaching and learning.  相似文献   

Physical demands of game-based training drills in women’s team handball     

Live S. Luteberget  Hege P. Trollerud  Matt Spencer 《Journal of sports sciences》2018,36(5):592-598

Game-based training drills are popular in team sports. This study compared two game-based training conditions and official matches in team handball. Thirty-one women players wore inertial measurement units in five training sessions and five official matches. In training, 3vs3 and 6vs6 game-based training conditions were performed with a 5-min duration. PlayerLoad? and high-intensity events (HIEs; >2.5 m · s^?1) were extracted from the raw data. Data were analysed using magnitude-based inferences and reported with effect sizes (ESs). PlayerLoad? · min^?1 from all positions combined was 11.37 ± 0.49 (mean ± 90% confidence limits) and 9.71 ± 0.3 for the 3vs3 and 6vs6 conditions, respectively. Backs (ES: 1.63), wings (ES: 1.91), and pivots (ES: 1.58) had greater PlayerLoad? in 3vs3 than 6vs6. Substantially greater HIE · min^?1 in 3vs3 occurred for all positions. There was substantially greater PlayerLoad? · min^?1 in 3vs3 and 6vs6 than match play for backs, wings, and pivots. Wings (ES: 1.95), pivots (ES: 0.70), and goalkeeper (ES: 1.13) had substantially greater HIE · min^?1 in 3vs3 than match play. This study shows greater PlayerLoad? and HIE in 3vs3 than 6vs6. Both game-based training conditions investigated in this study provide an overload in overall PlayerLoad?; however, additional exercises might be needed to overload HIE, especially for backs and pivots.  相似文献   

Goalkeeping in the soccer penalty kick     

John van der Kamp  Matt Dicks  Jose Antonio Navia  Benjamin Noël 《Sportwissenschaft》2018,48(2):169-175

The goalkeeper’s difficulty in the soccer penalty kick originates from the extreme spatiotemporal constraints of the situation. The present review claims that the current understanding is biased toward attributing a goalkeeper’s success in saving a penalty kick to perceptual–cognitive skill. To investigate the goalkeeper’s skill, researchers have often adopted video tasks. In doing so, they studied perceptual skill in isolation from action. We use affordance-based control theory to propose an alternative understanding and research methodology. We argue that goalkeepers in the penalty kick situation should regulate their actions in ways that sustain the perception of stoppability. To capture this, we outline the building blocks for a required lateral velocity model, in which the goalkeepers’ required actions are scaled to their maximum capabilities. In doing so, we provide new directions for research.  相似文献

What determines the return to education: An extra year or a hurdle cleared?     

Matt Dickson  Sarah Smith 《Economics of Education Review》2011,30(6):1167-1176

The 1973 Raising of the School Leaving Age from 15 to 16 has been used to identify returns to years’ schooling. However, because the first set of “high stakes” exams are taken in the UK at age 16, the reform affected the proportion with qualifications, as well as schooling length. In order to shed light on whether the returns reflect the extra length of schooling or the increase in qualifications, we exploit another institutional rule – the Easter Leaving Rule – which we argue only affected the probability of obtaining qualifications (and not the length of schooling). We find sizeable returns to academic qualifications – increasing the probability of employment by 40% points – and our results suggest that qualifications drive most of the returns to education.  相似文献   

Out of school: a phenomenological exploration of extended non-attendance     

Matt Baker  Felicity L. Bishop 《Educational Psychology in Practice》2015,31(4):354-368

The concept of “extended non-attendance” (“school phobia” or “school refusal”) was distinguished from truancy early in the twentieth century, and refers to children who fear school and avoid attending. Despite much subsequent research, outcomes for those affected remain poor, and their voices remain largely absent from the evidence base. The current study sought to address this by examining the experiences of four secondary-age children with extended attendance difficulties. Data consisted of semi-structured interviews conducted in participants’ homes, subsequently analysed using Interpretative Phenomenological Analysis. Although participants differed markedly in their perception of the causes of their non-attendance, their support experiences appear remarkably similar. Emergent themes include being disbelieved, experiencing fragmented support, and feeling blamed and punished. Implications for practitioners include the importance of ensuring early intervention, the need to consider the individual child, and the importance of making sure that local intervention practices are informed by the evidence base.  相似文献   

Educational policy or practice? Traversing the conceptual divide between subject knowledge,pedagogy and teacher identity in England     

Clare Woolhouse  Matt Cochrane 《欧洲师范教育杂志》2015,38(1):87-101

This research paper is framed by concerns about recent UK Government policy regarding the training of mathematics and science teachers in England and discusses how two cohorts of pre-service teachers negotiated the development of a professional identity while undertaking subject-specific training. The data reported upon were garnered in two ways; through an evaluation survey that received quantitative and qualitative responses from 159 teacher trainees and through focus groups conducted with 40 trainees. In the paper, the authors take the concept of ‘participation in communities of practice’ as a departure point to explore how trainees demonstrate their development of professional identities as chemistry, maths or physics teachers. In the conclusion, the authors consider the implications of the findings for pre-service teachers and teacher trainers given the current education climate of financial austerity being experienced across Europe.  相似文献

Organisational rules, codification and knowledge creation in inter-organisation cooperative agreements     

Arman Avadikyan  Patrick Llerena  Mireille Matt  Anne Rozan  Sandrine Wolff 《Research Policy》2001,30(9)

The aim of our paper is to analyse the process of collaboration between independent firms linked by a technological agreement in the energy field, with a specific focus on the degree of codification of inter-organisational rules. Considering the agreement as a collection of different types of more or less codified rules, we show that their degree of codification and some other characteristics have an impact on the process of inter-firm cooperation.The paper first provides an analytical framework defining the concept and the types of rules relevant for our purpose. A rule is conceived to solve a problem of allocation or creation of resources; it serves a main function which can be of a cognitive, incentive or coordination nature; it is ambivalent, i.e. it entails side functions in addition to the main one. Two theoretical propositions are then developed and largely confirmed by our empirical research results based on two detailed case studies in the emerging field of fuel cell (FC) technology.  相似文献   

Does research organization influence academic production?: Laboratory level evidence from a large European university     

Nicolas Carayol  Mireille Matt 《Research Policy》2004,33(8):1081-1102

The paper analyses scientific research production at the laboratory level. The evidence on which the study is based describes precisely the research activity over the period 1993-2000 of more than eighty labs belonging to Louis Pasteur University, a large and well-ranked European research university. The research organization of the labs is analysed by focusing on the characteristics of the research personnel in relation with the scores in two outcomes that are publications and patents. The paper proposes a five-classes typology of laboratories that highlights different styles of research organization and productivity at the laboratory level. It also studies the determinants of the publication performances of labs. We show how appropriate combinations of inputs in academic labs may be strongly associated to high publication performances. We find that combining full-time researchers and university professors in labs tend to preserve incentives. Highly publishing labs also patent. The size of the labs, the individual promotions, and the role of non-permanent researchers and of non-researchers are also underlined.  相似文献
