The longer a look at TV is maintained, the conditional probability that it will be further maintained rapidly increases for about 15 sec, after which it increases slowly. This increase in the conditional probability of maintaining a look is called "attentional inertia." An external audiovisual distractor stimulus was presented during 3- and 5-year-olds' TV viewing. The distractor was less effective in eliciting a head turn from the TV if it was presented after a look at the TV had been continuously maintained for at least 15 sec. If a head turn to the distractor following such a maintained look did occur, moreover, its reaction time was significantly increased. Parallel effects were found for the nonviewing pauses between looks. The results provide evidence of increasing attentional engagement as a look at TV is maintained. 相似文献

This is a summary of data on doctoral dissertations completed in instructional design and technology programs over the period 1977–88. During this period, 1,518 dissertations were completed at 46 different institutions, with nearly half completed at only 7 institutions. The 1,518 dissertations were chaired by 286 different professors, but approximately half were chaired by just 39 professors. The number per professor ranged from 89 to 1. Output was fairly steady over the 12 years, averaging 127 per year, with a low of 106 in 1980 and a high of 149 in 1983 and 1985. 相似文献

This paper analyses two pedagogical case studies (PCS) from a multidisciplinary perspective to highlight the problems of theoretical knowledge in tertiary physical education teacher education (PETE) programmes, school-based physical education (PE) practice and continuous professional learning (CPL) in PE. We argue that a critical view of tertiary PETE and PE teacher educator CPL practice or practices is particularly important if PETE programmes want to develop future PE and current teacher practitioners who are transformative agents. In setting up the pedagogical case study accounts, we recall common conversations about the bodies of knowledge in tertiary PETE programmes that have been positioned as problematic. The accounts highlight the existence of an artificial divide between PE educators as theory generators and both pre-service PE teachers and school-based PE practitioners as theory appliers. We suggest that part of the reason why this divide exists can be attributed to a general misunderstanding of theoretical and practical knowledge that have been wrongly compartmentalised into ‘theory’ and ‘practice’, and hence erroneously taught as isolated entities without any connection or direct link with each other, or the former considered to be less relevant and perhaps even irrelevant in practice. 相似文献

A controversy whether developmental dyslexia is qualitatively different from other forms of reading disability has existed
among reading specialists for many years because poor readers, regardless of the labels attached to them, resemble each other
symptomatically (i.e., in reading achievement). For this reason, it is difficult to establish a priori criteria based on symptoms
to identify dyslexia and compare it with other forms of reading disability. One possible solution to this impasse is to see
if poor readers differ in the etiology of their reading disability and, if they do, then to see whether one group of poor
readers fits the traditional definition of dyslexia. This strategy was adopted in the present study. In this paper, it was
hypothesized that the etiology of dyslexia is different from that of other forms of reading disability because there is a
difference in the components that malfunction in dyslexia and other forms of reading disability. Studies have shown that the
two components that account for a large proportion of variance in reading are decoding and comprehension. Previous studies
also indicate that dyslexic children are deficient in decoding skills but not necessarily in comprehension. In this study,
reading-disabled children were divided into two groups on the basis of their listening comprehension. Children whose listening
comprehension was at or above grade level were placed in one group; poor readers with below-grade-level listening comprehension
were placed in the second group. Both groups, however, were matched for reading comprehension. The two groups and a control
group of normal readers were administered a number of tasks that were designed to assess the efficiency of the components
of reading. It was found that poor readers with normal listening comprehension were deficient in tasks that involved grapheme-phoneme
conversion (Component I, decoding). When tested on tasks that minimized decoding requirements, their reading comprehension
was comparable to that of normal readers. In contrast, the group with sub-average listening comprehension was poor in measures
of reading comprehension, even when decoding requirements were minimal. With the exception of very few children, this group
also had adequate decoding skills. Because poor readers with normal listening comprehension had average or above average IQ,
they conform to the traditional definition of dyslexia. Poor readers with below average listening comprehension had below
average IQ and could be considered as “general reading backward.” It was, therefore, concluded that the etiology of developmental
dyslexia is different from that of general reading backwardness.
In this paper, the termetiology refers to proximal causal factors such as decoding and comprehension and not to distal causal factors such as genetic and
neurological characteristics. 相似文献

This study examines the relationship between the quality of school, family, and community partnership programs and student performance on state-mandated achievement tests. Data from 82 elementary schools, located in a large urban area, were collected to explore the relationship between family and community involvement and students' achievement test performance. Analyses show that, controlling for school characteristics, the degree to which schools were working to overcome challenges to family and community involvement predicted higher percentages of students scoring at or above satisfactory on state achievement tests. The findings suggest that schools' efforts to involve families and the community in students' learning may be a useful approach to help students achieve in school, especially for students in early elementary grades. Also, the findings illustrate the importance for schools located in large urban areas to address obstacles to family and community involvement to realize the benefits associated with family and community involvement. 相似文献

This paper explores how data-driven practices and logics have come to reshape the possibilities by which the teaching profession, and teaching professionals, can be known and valued. Informed by the literature and theorising around educational performativity, the constitutive power of numbers, and affective responses to data, it shows how different US educators experienced, and came to embody, new forms of numbers-based accountability. Drawing on interviews with teachers, and school- and district-level leaders, as well as relevant school-based documents, it is argued that such data are now both effective (i.e. they change ‘what counts’ within the profession) and affective (i.e. they produce new expectations for teachers to profess data-responsive dispositions over actual educative practices). This prevalence and use of data have combined not only to change teaching into a ‘data profession’, but also to change teachers into ‘professors’ of data. 相似文献

Corporatising school leadership through hysteresis 总被引:1,自引:0,他引:1
Steven J. Courtney 《British Journal of Sociology of Education》2017,38(7):1054-1067
This article builds on the established notion that schools are hierarchised through policy, accruing different amounts and types of symbolic capital, by examining how this is reflected in the habitus of the leaders of new, privileged school types. The article uses Bourdieu’s concept of hysteresis, or a dislocation between the habitus which formerly produced success in the field and the habitus currently necessary following changes in field conditions. Using crafted narrative accounts from two headteachers, I argue that rather than simply being an effect of change, hysteresis may be an actively sought outcome whereby the state intervenes in a field – education – to deprivilege welfarist leaders and privilege corporatised leaders through structurally facilitating their habitus and mandating its dispositions for the field. However, insofar as deprivileged actors may draw strength and an identity from rejecting corporatisation, the concept of hysteresis must be extended to include notions of agentic dissidence. 相似文献
