In this study, we examined how perceptual-motor expertise and watching experience contribute to anticipating the outcome of opponents' attacking actions in beach volleyball. To this end, we invited 8 expert beach volleyball players, 8 expert coaches, 8 expert referees, and 8 control participants with no beach volleyball experience to watch videos of attack sequences that were occluded at three different times and to predict the outcome of these situations. Results showed that expert players and coaches (who were both perceptual-motor experts) outperformed the expert referees (who were watching experts but did not have the same motor expertise) and the control group in the latest occlusion condition (i.e., at spiker-ball contact). This finding suggests that perceptual-motor expertise may contribute to successful action anticipation in beach volleyball.  相似文献   

Puppets on a string in a theatre of display? Interactions of image,text, material,space and motion in The Family of Man (ca. 1950s–1960s)     

Karin Priem  Geert Thyssen 《Paedagogica Historica: International Journal of the History of Education》2013,49(6):828-845

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   

Self‐assessment in university assessment of prior learning procedures     

D. Joosten‐Ten Brinke  D. M. A. Sluijsmans  W. M. G. Jochems 《International Journal of Lifelong Education》2013,32(1):107-122

Competency‐based university education, in which lifelong learning and flexible learning are key elements, demands a renewed vision on assessment. Within this vision, Assessment of Prior Learning (APL), in which learners have to show their prior learning in order for their goals to be recognised, becomes an important element. This article focuses on a first step in APL, namely students’ self‐assessment of their prior learning before entering university education. The main aim of the presented study is to examine the suitability of the use of self‐assessment in APL. First, in an explorative study, the main sources for self‐assessment are derived and the relation between sources and domain of study is investigated. Second, in a pre‐test post‐test research design, the hypothesis that students’ self‐assessment of prior learning related to a course changes after studying a domain‐specific course is tested. Pre‐test results reveal that students indicate that they have prior knowledge related to the chosen university programme. In general, this prior learning is obtained from study experience, work experience, books, newspapers, magazines, the Internet, TV, radio, film or video. A relation is found between the type of source and the university programme. The hypothesis that students change their self‐assessment after a study period could not be confirmed. Based on these results, it is concluded that self‐assessment in APL might be a suitable tool. Implications for further research are discussed.  相似文献   

Symptomatology in adolescents following initial disclosure of sexual abuse: The roles of crisis support, appraisals and coping     

Sarah Bal  Geert Crombez  Ilse De Bourdeaudhuij  Paulette Van Oost 《Child abuse & neglect》2009,33(10):717-727

ObjectiveThe present study examined possible explanations for symptom development and variability in sexually abused adolescents. A theoretical model of sexual abuse, in which appraisal, coping and crisis support play prominent roles, was tested in a clinical group of 100 sexually abused adolescents.MethodParticipants, aged 12–18 years, completed questionnaires regarding severity of abuse, negative appraisals, crisis support, coping strategies, and trauma-related stress symptoms.ResultsSince severity of abuse had no influence on the association between appraisals and symptoms it was eliminated from our model. Structural equation modeling analyses showed a significant interrelationship between the examined concepts. Adolescents who appraised the abuse as more threatening showed more internalizing and externalizing trauma symptoms. Moreover, more negative appraisals were associated with more avoidance as well as with more active coping strategies. Direct crisis support was associated with less negative appraisals and with the use of more active coping strategies.ConclusionsThe study showed that especially the buffering role of crisis support and the role of negative appraisals explained symptom development and variety in sexually abused adolescents.Practice implicationsAdaptation to sexual abuse includes the ways in which adolescents perceive the event as threatening and harmful, how they cope with the abusive experience, and how they receive direct support from their family. Clinicians, therefore, need to expand the focus of their assessments beyond age- and trauma-specific symptoms, to age- and trauma-specific appraisals, coping, and social support. The assessment of these factors should take place as soon as possible after the disclosure of the abuse. Individualized treatment plans and clinical interventions need to be based on these personal and environmental variables, rather than reliance on the influence of abuse-related characteristics, such as the severity or type of abuse.  相似文献   

Rethinking agency as an assemblage from change management to collaborative work     

Inge Van de Putte  Elisabeth De Schauwer  Geert Van Hove  Bronwyn Davies 《International Journal of Inclusive Education》2018,22(8):885-901

The movement towards inclusion comes together with a neoliberal audit mentality whereby individuals are held responsible for the transformations. The Special Educational Needs Coordinators (SENCOs) are seen as ‘change agents’ whose task it is, to support teachers in adapting their approach to optimise the chances for children with special needs in regular schools. In this paper, we want to problematise the ‘responsibility-blame discourse’ and look differently at agency. By using a diffractive methodology based on collaborative work, in which we have used material images of the workplace of the SENCO, and read-the-data-while-thinking-with-theory, we deconstruct the individualisation of agency. The SENCOs are no longer seen as separate individual humanist subjects where agency is solely lodged in the body of an individual agent [Barad, K. 2007. Meeting the Universe Halfway: Quantum Physics and the Entanglement of Matter and Meaning. Durham: Duke University Press] but the SENCOs are part of the intra-active entanglement of multiple agencies, of an assemblage. This re-conceptualisation of agency leads to a different approach to inclusion, in which the participants in any encounter can work as part of the assemblage to develop communities capable of re-thinking practice and transforming it into a place where children with special needs become legitimate members of the school.  相似文献   

Gender and learning: Comparing two theories     

Sabine Severiens  Geert Ten Dam 《Higher Education》1998,35(3):329-350

The research domain of gender and learning seems to develop in two different areas. In one area learning is investigated by using general theories on learning and instruction. In the second area, gender plays a central role in the theoretical frameworks. The present article compares two theories from these areas using a general perspective and a gender perspective. By doing this, we intend to combine knowledge resulting from the two distinct areas and possibly take the research domain of gender and learning a step further. The theories in the comparison concern Vermunt's learning conceptions (1996) and Baxter Magolda's ways of knowing and patterns of reasoning (1992). It turns out that a number of relations seems to exist on a conceptual level between these two theories, but the relations could not be confirmed empirically. In the discussion, the results are elaborated upon and possible future research is suggested.  相似文献

Designing innovative learning environments to foster communities of learners for students in initial vocational education     

Annoesjka Boersma  Geert ten Dam  Willem Wardekker  Monique Volman 《Learning Environments Research》2016,19(1):107-131

In this study, the concept of ‘community of learners’ was used to improve initial vocational education. The framework of a ‘community of learners for vocational orientation’ that we present offers both a theoretical understanding of teaching–learning processes in initial vocational education and heuristics for the design of innovative learning environments for optimising these processes. In a design research study, we investigated if, and how, learning environments designed on the basis of these heuristics fostered communities of learners for vocational orientation, in which students experience to learn in a shared, meaningful, reflective and transfer-oriented way. We examined students’ perceptions of the learning environment and their learning activities during eight curriculum units specifically designed to foster the communities of learners. During almost all of the units that we designed, students found themselves learning in a more shared, meaningful, reflective and transfer-oriented way than during regular units. We conclude that the proposed heuristics had been useful starting points for the design of innovative learning environments that foster communities of learners for vocational orientation. In addition, we show how the heuristics can be elaborated for a particular school, based on practical and pedagogical content knowledge of teachers, as well as students’ perceptions of the learning environment and their learning activities.  相似文献   

Retardation of rabbit nictitating membrane conditioning following US preexposures depends on the distribution and number of US presentations     

Michael E. Saladin  William N. Ten Have  Zalman L. Saper  Jordan S. Labinsky  Robert W. Tait 《Learning & behavior》1989,17(2):179-187

Retarded conditioned response (CR) acquisition produced by unconditioned stimulus (US) preexposures has been attributed either to interference resulting from contextual conditioning or to habituation of the US. Both perspectives assume that the amount of retardation is directly related to the number of US preexposures. This assumption was examined in two experiments. In Experiment 1, separate groups of rabbits received 200 paraorbital shock US preexposures either in one session or spread equally over 10 daily sessions. Subsequently, all subjects received 150 CS-US pairings. Acquisition of nictitating membrane CRs was retarded relative to a naive control group only in the group that received the preexposures over 10 sessions. Thus, the number of US preexposure sessions, rather than the number of US preexposures, determined whether or not retarded acquisition was observed. In Experiment 2, four groups of rabbits received 1, 5, 20, or 40 shock US preexposures in each of 10 sessions. Over the subsequent 150 CS-US pairings, similar levels of retarded CR acquisition were observed in groups that received 20 and 40 US preexposures per session, a weak retardation effect was observed with 5 preexposures per session, and no retardation was observed with 1 preexposure per session. Thus, Experiment 2 suggested that retarded CR development was not greatly influenced by increasing the number of US preexposures above some minimum threshold number of exposures per session. Implications for current theories were discussed.  相似文献
