There is little research investigating the maintenance of perceptual-cognitive expertise in general and even less comparing coaches of different ages. The aim of this study was to test for perceptual-cognitive differences between age groups, licence levels, and their interaction. This study investigated differences in skilled performance between young and middle-aged coaches of three different skill levels. Participants performed an accuracy-oriented pattern recall (mean distance in pixel) and a time-oriented flicker test (mean detection time in ms). There were some significant differences between age groups and between skill groups for both tests, but no interactions. For the pattern recall test, the effect sizes were larger for skill level differences, while for the flicker test effects were larger for ageing. These results suggest coaches are able to maintain accuracy skills better than reaction timed tasks. This is in line with findings on speeded performance in general populations, which show declines with age. Moreover, results also support findings on perceptual expertise in skills where accuracy was important. 相似文献

This study examined the underlying structure of the Nonverbal Literacy Assessment (NVLA), an instrument designed to measure emergent literacy for K–fourth‐grade students with severe developmental disabilities. The NVLA was conceptualized as having six constructs that reflected emergent literacy skills: (a) phonemic awareness, (b) phonics, (c) comprehension, (d) vocabulary, (e) listening comprehension, and (f) text awareness. Confirmatory factor analysis using data from 207 student administrations was used to examine the six‐factor model and two alternative models. Results suggested that all three models fit the data, but the high corrections coefficients among the constructs suggested that a one‐factor model of emergent literacy was the best‐fitting model. Implications and limitations are discussed. © 2010 Wiley Periodicals, Inc. 相似文献

Intellectual Disability and Developmental Risk: Promoting Intervention to Improve Child and Family Well‐Being 下载免费PDF全文
Keith A. Crnic Cameron L. Neece Laura Lee McIntyre Jan Blacher Bruce L. Baker 《Child development》2017,88(2):436-445
Initial intervention processes for children with intellectual disabilities (IDs) largely focused on direct efforts to impact core cognitive and academic deficits associated with the diagnosis. Recent research on risk processes in families of children with ID, however, has influenced new developmental system approaches to early intervention. Recent risk and resilience processes are reviewed that connect stress, family process, and the high rates of behavioral problems in children with ID that have substantial influence on child and family outcomes. These models are linked to emerging evidence‐based intervention processes that focus on strategic parent skill training and mindfulness interventions that reduce parental stress and create indirect benefits for children's behavioral competencies. A family‐focused developmental systems approach (M. J. Guralnick, 2011) is emphasized. 相似文献

A new learning unit in chemistry, Case-based Computerized Laboratories (CCL) and Computerized Molecular Modeling (CMM) was developed at the Technion. The CCL and CMM curriculum integrates computerized desktop experiments and molecular
modeling with an emphasis on scientific inquiry and case studies. Our research aimed at investigating the effect of the CCL
and CMM learning environment on students’ higher-order thinking skills of question posing, inquiry, and modeling. The experimental
group included 614 honors 12th grade chemistry students from high schools in Israel who studied according to this learning
unit. The comparison group consisted of 155 12th grade chemistry honors students who studied other chemistry programs. Pre-
and post-tests questionnaires were used to assess students’ higher-order thinking skills. Students’ responses were analyzed
using content analysis rubrics and their statistical analysis. Our findings indicated that the scores of the experimental
group students improved significantly in question posing, inquiry and modeling skills from the pre-test to the post-test.
The net gain scores of the experimental group students were significantly higher than those of their comparison peers in all
three examined skills. In modeling skills, experimental group students significantly improved their achievements in making
the transfer from 3D models to structural formulae, but only about half of them were able to transfer from formulae to 3D
models. By presenting a case-based chemistry assessment tool and content analysis of students’ responses in this paper, we
enable teachers and educators to analyze their students’ higher-order thinking skills both qualitatively and quantitatively. 相似文献
