Little is known about how specific iPad applications affect parent–child story‐sharing interactions. This study utilises a case‐study approach to provide an insight into the patterns of interaction, which emerge when a mother and her 33‐month‐old daughter share a self‐created, audio‐visual ‘iPad story’. Multimodal analysis allowed us to gain insights into the complex interaction patterns orchestrated in this new, personalised story‐sharing medium. We found that the app‐mediated story‐sharing context produced a harmonious and smooth interaction, achieving a coherence that is typical of ‘happy’ oral stories. We suggest that the observed interaction resembles that of experiencing a piece of art, and we highlight the need for a holistic approach to understanding the implications for research and practice of children's interactions during multimedia story sharing.  相似文献

Surface acoustic wave (SAW) devices with 64 μm wavelength were fabricated on a zinc oxide (ZnO) film deposited on top of an ultra-smooth nanocrystalline diamond (UNCD) layer. The smooth surface of the UNCD film allowed the growth of the ZnO film with excellent c-axis orientation and low surface roughness, suitable for SAW fabrication, and could restrain the wave from significantly dissipating into the substrate. The frequency response of the fabricated devices was characterized and a Rayleigh mode was observed at ∼65.4 MHz. This mode was utilised to demonstrate that the ZnO/UNCD SAW device can be successfully used for microfluidic applications. Streaming, pumping, and jetting using microdroplets of 0.5 and 20 μl were achieved and characterized under different powers applied to the SAW device, focusing more on the jetting behaviors induced by the ZnO SAW.  相似文献

This ESRC‐funded study explores how 3‐year‐old children use a range of ‘voices’ during their first year in pre‐school, investigating how they make and express meaning ‘multimodally’ through combinations of talk, body movement, facial expression and gaze in the two different settings of home and playgroup. Using longitudinal ethnographic video case studies of four children, two boys and two girls, the study identifies patterns in the children's uses of different communicative strategies that relate to the dynamics of the institutional and immediate contexts in which they are situated. The findings imply that the current focus on talk in the early years may be detracting from the diversity of ways children make and express meaning.  相似文献

Our aims were to improve our understanding of human performance before 1850 and to put nineteenth- and twentieth-century performances into a broader historical context. Consequently, 536 foot-races performed in Britain in the 'long' eighteenth century were identified, 53 of which were analysed in detail. The best performances at the end of the eighteenth century were compared with those at the end of the nineteenth and twentieth centuries. The data for the nineteenth century were marginally better than those for the eighteenth century up to 20 km, but beyond that Thomas Carlisle's time, set in about 1740, of 2 hours for 21 miles was outstanding. Current records are shown to be better than earlier records at all distances from 5 km up to the marathon, the superiority being most pronounced from 15 km upwards.  相似文献

Using mathematical analysis, we examined the three baton exchanges that occur during a 4×100 m relay. Identical representative 100 m running performances were assumed for each of four elite male athletes, and the calculations were made for optimal or near-optimal positions of the baton exchanges and starting positions of the athletes running the second, third and fourth legs as determined by Ward-Smith and Radford (2002). In this paper, we focus on the calculation of the checkmark position and demonstrate the complexity of the baton exchange process. The results of the mathematical analysis show that, for optimal performance, the checkmark should be located differently for each of the three exchanges in a single race, and is further affected by lane draw and free distance (the distance between the runners at the baton exchange). For a representative free distance of 1 m at each exchange, the checkmark distance ranges from a minimum of 11.04 m at the third exchange in Lane 1 to 12.20 m for the first exchange in Lane 8. Failure by teams and their coaches to consider adequately the complexities of the baton exchanges may help explain why 25.5% of teams in recent World Championships were disqualified or did not finish.  相似文献

This paper tells of the social experiences of three four‐year‐old children with learning disabilities as they negotiate their daily lives in their homes and early education settings in England. We apply a social model of childhood disability to the relatively unexplored territory of young children and use vignettes drawn from video observation to explore the interactive spaces contained in settings with different cultures of inclusion. Using a multimodal approach to the data we show the nuanced ways in which the children enact their agency. We explore the relationships between agency, culture and structure, and argue that children with learning disabilities are active in making meaning within social and relational networks to which they contribute differently depending on the barriers to doing and being that each network presents. Thus, the paper provides an original use of the notion of distributed competence.  相似文献

This paper discusses concepts of learning through ‘collaborative multimodal dialogue’. It draws on an ESRC‐funded study (RES‐000‐22‐2451) investigating 3‐ and 4‐year‐old children's encounters with literacy as they engage with a range of printed and digital technologies at home and in a nursery. The study goes beyond analysis of spoken language, giving a more complete understanding of literacy learning processes through detailed analysis of how children use multiple communicative modes as they experience literacy in different media. These experiences underpin metacognitive development and are crucial to children's abilities to act strategically in future situations. Drawing on notions of literacy as social practice, this paper discusses how the advent of new technologies has introduced new dimensions into young children's literacy learning, the implications of which have not yet been fully recognised in early years policy guidance, training or practice.  相似文献

Science curricula and teaching methods vary greatly, depending in part on which facets of science are emphasized, e.g., core disciplinary ideas or science practices and process skills, and perspectives differ considerably on desirable pedagogies. Given the multi-faceted nature of science and the variety of teaching methods found in practice, it is no simple task to determine what teaching approaches might be most effective and for what purposes. Research into relative efficacy faces considerable challenges, with confounding factors, ambiguities, conflations, and lack of controls being threats to validity. We provide a conceptual framework characterizing the many teaching strategies found in practice as being variants of two fundamental contrasting epistemic modes, and we disentangle conflations of terms and confusions of constructs in both teaching practice and research. Instructional units for two science topics were developed in parallel in the alternative epistemic modes, differing in concept learning paths but otherwise equivalent. We conducted a randomized controlled study of the comparative efficacy of the two modes for learning core disciplinary ideas, using operationally defined active-direct and guided-inquiry teaching methods. Five middle school teachers taught each unit in both modes over 4 years of classroom trials in an 8-day summer program for eighth grade students. Student understanding of core ideas was assessed using pre- and post-tests, and learning gains were analyzed by mode, teacher, topic, and trial year. Although routes to concept understanding were very different in the two modes, eventual student learning gains were similar, within statistical variation. Efficacy variations between and within teachers were greater than between modes, indicating the importance of teacher effects on student achievement. Findings suggest that teachers need not be bound to one mode throughout and can flexibly decide on the pedagogical approach for each concept and situation, on several grounds other than efficacy of core content acquisition alone.  相似文献

This paper focuses on parents' perspectives of combining special and mainstream services for their children in the early years, offering insights into: how parents came to make this choice for their children's education; what parents expected from the combined provision and how their expectations were being met in practice. The data presented formed part of a small‐scale, UK‐based study that investigated local discourses and practices operating for young children within a global context of commitment to inclusion. Despite moves towards inclusive early years education in the UK, many parents of young children identified as having special educational needs opt for a combination of both inclusive and special early years settings. A survey sent to early years providers, voluntary groups and parents in three local education authorities (LEAs) in southern England, revealed that the practice of combining placements was widespread. Follow‐up interviews with parents of five children revealed rich detail about the processes of choice making and parents' expectations and experiences of combined provision. The research findings have clear implications for the development of inclusive education and its appeal to parents, who may need convincing that it can offer sufficient specialist expertise and resources.  相似文献
