We tested the hypothesis that quiet eye, the final fixation before the initiation of a movement in aiming tasks, is used to scale the movement's parameters. Two groups of 12 participants (N = 24) threw darts to targets in the horizontal and vertical axes under conditions of higher (random) or lower (blocked) target variability. Supporting our predictions, random practice and target changes in the vertical axis led to longer quiet eye duration than did blocked practice and target changes in the horizontal axis. Our data suggest that quiet eye is not simply a mediating factor in accuracy, but is responsive to the task's programming demands, being influenced by the necessity to reparameterize the movement from one trial to the next.  相似文献

We report on an international study about mathematics students’ ideas of how they will use mathematics in their future study and careers. This builds on our previous research into students’ conceptions of mathematics. In this paper, we use data from two groups of students studying mathematics: those who participated in an in-depth interview and those who completed an open-ended questionnaire. We found that their responses could be grouped into four categories: don’t know; procedural skills; conceptual skills; and professional skills. Although some students held clear ideas about the role of mathematics, many were not able to articulate how it would be used in their future. This has implications for their approach to learning and our approach to teaching.  相似文献

The report summarizes a presentation given at the 2015 NASIG conference. It outlines metadata used by Project CERES, a print preservation and digitization project supported by a partnership between the United States Agriculture Information Network and the Center for Research Libraries. It also outlines metadata guidelines used to disclose print holdings committed for preservation and provides tips on creating efficiencies in gathering the detailed issue level data and providing quality assurance for digitization. Gathering detailed metadata to support the preservation of print is an investment in the preservation of essential scholarly resources. Project CERES can be used as a model for other programs coupling preservation and digitization.  相似文献

In four carefully selected samples of 8- to 10-year old children with dyslexia (but age adequate arithmetic skills), dyscalculia (but age adequate reading skills), dyslexia/dyscalculia and controls a domain-general deficit in rapid automatized naming (RAN) was found for both dyslexia groups. Dyscalculic children exhibited a domain-specific deficit in rapid naming of quantities. This finding is in line with recent assumptions that dyscalculia is associated with a neurobiological deficit in the processing of numerosities. In the dyslexia/dyscalculia group, RAN deficits were additive, that is, the dyslexia/dyscalculia group exhibited the sum of the deficits found in the dyslexia only and dyscalculia only groups. This finding suggests that the cognitive bases of dyslexia and dyscalculia are independent from each other. Within the naming speed paradigm no differential impact of special demands on the executive functions inhibition and shifting was found for any of the four groups.  相似文献

The present research explored the relationship between high school students' self-reported delinquency and the importance of their social reputations. The prevalence of self-reported delinquency was investigated in a sample of 965 (467 males, 498 females) Years 8 to 12 students attending high schools in Brisbane and Perth, Australia. The results revealed that males are significantly more prone to all forms of delinquent behaviour than their female peers. Most forms of delinquency appeared to peak at Year 9, with the exception of drug use which increased with age. A cluster analysis was performed on the prevalence data and students were separated into two groups: students with high and low involvement in delinquency. The reputations of students with high and low delinquency involvement were investigated. Students identified as having low involvement in delinquency desired a more conforming reputation than those with high involvement. Females also desired a more conforming reputation than their male counterparts. In relation to year level, junior high school students were less conforming than senior high school students. Ways to address the powerful nature of adolescent reputations and the link between reputational status and involvement in delinquent activities are highlighted.  相似文献

As noted by Fremer and Olson, analysis of answer changes is often used to investigate testing irregularities because the analysis is readily performed and has proven its value in practice. Researchers such as Belov, Sinharay and Johnson, van der Linden and Jeon, van der Linden and Lewis, and Wollack, Cohen, and Eckerly have suggested several statistics for detection of aberrant answer changes. This article suggests a new statistic that is based on the likelihood ratio test. An advantage of the new statistic is that it follows the standard normal distribution under the null hypothesis of no aberrant answer changes. It is demonstrated in a detailed simulation study that the Type I error rate of the new statistic is very close to the nominal level and the power of the new statistic is satisfactory in comparison to those of several existing statistics for detecting aberrant answer changes. The new statistic and several existing statistics were shown to provide useful information for a real data set. Given the increasing interest in analysis of answer changes, the new statistic promises to be useful to measurement practitioners.  相似文献

A review of estimates of the incidence of emotional disturbance/problem behavior in school-aged children leads to the conclusion that schools should anticipate a need for alternative programming for the 2–3% of their students predicted to have recurrent or persistent problems in adjusting to school situations. In addition, there is a need to assist teachers in dealing with the stresses created by the high incidence of transient problem behavior affecting 25–30% of the total school population. Some programming possibilities are suggested.  相似文献

Scopus, EBSCO, ERIC and British Education Index were interrogated in a systematic review of primary research since 2014 addressing expert practice and outcomes in education and care for young people with special educational needs and disability in the UK. Grey literature and studies of medical settings, preschool children, mainstream education or professional education were excluded. Quality was gauged by effect sizes, risk of bias and the Critical Appraisal Skills Programme. The search identified 7058 items. Twenty-eight studies were included, with 1839 participants of 4–22 years. Risk of bias was low, with effect sizes from small to extremely large. The qualitative studies were rigorous. Expert practice with positive outcomes was evidenced in comprehensive assessment, enhancing engagement and personalised interventions. Correction of visual problems, use of humanoid robots, and tested models were generally effective. There was rigorous evidence for efficacy of frameworks and reasonable evidence for creative approaches to physical activity. Drama lessons were valued. Standing frame use improved peer interaction or caused segregation. Disparity between problem identification and planned support in education health and care plans, and addressing personal and physical health factors were problematic. The voice of young people was lacking. More training was required in augmented and alternative communication.  相似文献
