Time series analysis of knowledge of results effects during motor skill acquisition     

J R Blackwell  R W Simmons  J A Spray 《Research quarterly for exercise and sport》1991,62(1):10-17

Time series analysis was used to investigate the hypothesis that during acquisition of a motor skill, knowledge of results (KR) information is used to generate a stable internal referent about which response errors are randomly distributed. Sixteen subjects completed 50 acquisition trials of each of three movements whose spatial-temporal characteristics differed. Acquisition trials were either blocked, with each movement being presented in series, or randomized, with the presentation of movements occurring in random order. Analysis of movement time data indicated the contextual interference effect reported in previous studies was replicated in the present experiment. Time series analysis of the acquisition trial data revealed the majority of individual subject response patterns during blocked trials were best described by a model with a temporarily stationary, internal reference of the criterion and systematic, trial-to-trial variation of response errors. During random trial conditions, response patterns were usually best described by a "White-noise" model. This model predicts a permanently stationary, internal reference associated with randomly distributed response errors that are unaffected by KR information. These results are not consistent with previous work using time series analysis to describe motor behavior (Spray & Newell, 1986).  相似文献   

Conservation Heating 24 Years On     

Nigel Blades  Katy Lithgow  Sarah Staniforth  Bob Hayes 《文物保护研究》2018,63(5):15-21

ABSTRACT

Control of relative humidity (RH) for collections care is challenging in U.K. historic houses because they are often highly ventilated with poor heat retention, a porous building fabric and naturally tend to high (60–80%) RH if unheated. The significance of the building means that large-scale modifications and installation of air handling systems may be unfeasible and undesirable for the conservation of the building. In the late 1980s the National Trust, for English, Wales and Northern Ireland, investigated conservation heating as an RH control method that works with the natural environment of historic buildings, mimicking historic heating and requiring only modification of existing heating services or a light touch installation of new heating systems. The National Trust adopted conservation heating as its preferred method for environmental control in historic buildings from the 1990s. This method was presented at the IIC 1994 Ottawa congress on preventive conservation. Conservation heating has since been adopted by many historic house management organisations, particularly across north-west Europe, where it is well suited to the climate. This paper reviews conservation heating developments implemented by the National Trust since 1994, in response to a changing external context, new knowledge and developments in operational practice.  相似文献

Angle and rotation: Effects of different types of feedback on the quality of response     

Malcolm Simmons  Peter Cope 《Educational Studies in Mathematics》1993,24(2):163-176

The study compares the levels of response to angle/rotation problems presented on screen with a Logo microworld with the levels of response to similar problems presented on paper. Pairs of children aged from 9 to 11 who had little or no experience of Logo completed the problems in about 40 minutes. Pairs of children completed the problems over a period of eight weeks. The responses, classified using the SOLO taxonomy (Structure of Observed Learning Outcomes), suggested that the effect of the immediate feedback of the screen turtle heading was to inhibit moves to a higher level of response compared to those levels of response reached when responding to paper tests.  相似文献   

Nurseries and emotional well‐being: evaluating an emotionally containing model of professional development     

Peter Elfer  Katy Dearnley 《Early Years: An International Journal of Research and Development》2007,27(3):267-279

Despite official endorsement of attachment principles in nursery work, these are often not translated into nursery practice. One possible reason for this is that staff training does not sufficiently address the personal implications and anxieties that children's attachments may entail for practitioners. Working from a psychoanalytic perspective on organisational functioning and group learning, this paper describes action research with a group of nursery heads who participated in a professional development programme designed specifically to explore emotional experience in professional work. The positive evaluations of the programme by heads and their staff are described including examples of experiential learning and of increased staff awareness about, and responsiveness to, the emotional experience of children. However, the research also concluded that sustained effectiveness of the model is likely to be dependent on an ongoing culture of attention to the emotional experience of nursery staff within nursery umbrella organisations.  相似文献   

The effectiveness of post-16 pathways for gaining employment associated with undergraduate degree study     

Katy Joy 《Journal of Further & Higher Education》2018,42(7):953-968

This article sets out to examine the effectiveness of five different post-16 study pathways and the impact that spending time away from education has on gaining employment associated with an undergraduate degree. It also explores advice and guidance for students looking at post-16 study options, higher education and employment. An initial online survey was used, followed by case studies to form a mixed-method approach. The findings suggest that a vocational pathway better prepares students for making decisions around employment and study in comparison to the more traditional A Level pathway. They also highlight that a period of one to four years after finishing post-16 study and starting undergraduate degree study is the most effective for students to gain employment associated with their undergraduate degree. Finally, it was found that most participants did not have positive experiences with advice and guidance regardless of their pathway.  相似文献

Season-of-birth bias in association football     

Simmons C  Paull GC 《Journal of sports sciences》2001,19(9):677-686

In this longitudinal study, we assessed the frequency of birth dates for boys selected for the Football Association National School. Birthdays were divided into three periods of the year: January to April, May to August and September to December. We compared data over a 5 year period and concluded that there is indeed a bias towards selecting older children. Furthermore, analysis of separate data revealed a shift of bias when comparing two different start dates, namely September and January. Our findings show that the youngest children from the January start date (born September to December) are selected significantly more often than the youngest children from the September start date (born May to August). Interestingly, even when the influence of body mass was reduced, the selection bias towards the older players remained.  相似文献

The role of special schools for children with profound and multiple learning difficulties: is segregation always best?     

Ben Simmons  Phil Bayliss 《British Journal of Special Education》2007,34(1):19-24

The education of young people with profound and multiple learning difficulties continues to raise challenges and controversies. In this article, Ben Simmons, an ESRC funded PhD student and research assistant, and Phil Bayliss, programme director for the masters degree in special education and disability, both based in the School of Education and Lifelong Learning at the University of Exeter, describe their research into provision for pupils with profound and multiple learning difficulties in a special school in the south west of England. Their work, based in an interpretivist, qualitative approach, set out to illuminate issues relating to the inclusion of pupils with profound and multiple learning difficulties. The findings presented here suggest that the school, in spite of its strong reputation, struggled significantly to provide appropriate learning experiences for pupils with profound and multiple learning difficulties. Ben Simmons and Phil Bayliss discuss the need for improved staff development opportunities focused on enhancing current levels of knowledge and skills. They conclude by calling for a reappraisal of the established view that special schools necessarily provide the best learning environment for pupils with profound and multiple learning difficulties.  相似文献
