The current work examines children's sensitivity to rime unit spelling–sound correspondences within the context of early word reading as a way of assessing word‐specific influences on early word‐reading strategies. Sixty 6–7‐year‐olds participated in an experimental reading task that comprised word items that shared either frequent or infrequent rime unit correspondences. Retrospective self‐reports were taken as measures of strategy choice. The results showed that the children were more accurate in identifying word items that shared a common rime unit (consistent items) when compared with those containing infrequent rime units (unique and exception items). Moreover, while nonlexical (phonological) attempts were most frequently applied across all word types, these resulted in lower levels of accuracy, especially for the exception word items. The current data support the argument that children are increasingly sensitive to rime unit sound–spelling correspondences during the early stages of their word reading and the nature of these word‐specific orthographic representations shape their reliance on using particular lexical or non‐lexical‐based word‐reading strategies. 相似文献

Testing a component model of reading comprehension in a randomized controlled trial, we evaluated the efficacy of 4 interventions that were designed to target components of language and metacognition that predict children’s reading comprehension: vocabulary, listening comprehension, comprehension of literate language, academic knowledge, and comprehension monitoring. Third- and 4th-graders with language skills falling below age expectations participated (N = 645). Overall, the component interventions were only somewhat effective in improving the targeted skills, compared to a business-as-usual control (g ranged from ?.14 to .33), and no main effects were significant after correcting for multiple comparisons. Effects did not generalize to other language skills or to students’ reading comprehension. Moreover, there were Child Characteristic × Treatment interaction effects. For example, the intervention designed to build sensorimotor mental representations was more effective for children with weaker vocabulary skills. Implications for component models of reading and interventions for children at risk of reading comprehension difficulties are discussed. 相似文献

The transport of thermal energy in thermodynamics is described as the product of entropy flow and of the absolute temperature, in analogy to the volume flow and pressure in oil hydraulics and to electric charge flow (= current) and voltage in electronics. Bond graphs are shown to be especially suitable to describe the splitting of applied thermal energy into internal energy and external mechanical work. Transformers and the 0- and 1-junctions of Paynter can illustrate various entropy flow processes, including Carnot engines and heat exchangers. Entropy flow in heat conduction is distinguished from entropy convection, or transport by moving mass, where the entropy/temperature characteristic or equation of state is important. Irreversibilities are represented by impedance transformers reducing temperature and increasing entropy flow but conserving power. 相似文献

In New Zealand, Māori (indigenous New Zealanders) and Pacific students tend not to attain the same levels of educational success
as Pākehā (New Zealanders of European descent). Addressing this problem is a particular challenge in the sciences. The kaupapa
(values-base) of Te Rōpū Āwhina (Āwhina) is to produce Māori and Pacific professionals to contribute to Māori and Pacific
development and leadership through the creation of an inclusive off- and on-campus whānau (extended family) environment where
high expectations, aspirations and achievement, collective success, and reciprocity are normalised. This paper reviews theories
and practices of recruitment and retention relevant to Māori and Pacific students at tertiary level, presents the rationale
for Āwhina in the Faculties of Science and Architecture and Design at Victoria University of Wellington, and assesses the
impact of the whānau. Based on analyses of quantitative measures of student achievement, and biennial surveys of student responses
from the first 6 years of Āwhina, it is suggested that the results are consistent with improving Māori and Pacific graduate
and postgraduate achievement and retention. Potential implications for efforts to reduce disparities in tertiary education
in New Zealand and elsewhere are summarised. 相似文献

This inquiry explores who is the ‘good teacher of color’. Through Michel Foucault's notion of biopower and disciplinary power, the analysis attempts to problematize the subject-position of ‘teacher of color’ by exploring how a Latino intern and a Latina intern negotiated their subjectivity in a large diverse school district. Participants' construction of subjectivity was found to be located within the nexus of the school district, the university, and the Latino counter-discourse through which biopower and disciplinary power operated. 相似文献

This article estimates the effects of school expenditure on school performance at Key Stage 4 in England, over the period 2003–07 during which real per pupil expenditure increased rapidly. It adds to previous investigations by using dynamic panel analysis to: exploit time series data on individual schools that only recently has become available; adjust for the potential endogeneity not only of expenditure but also of other determinants of performance; and differentiate the short‐run and the (higher) long‐run attainment effects of spending changes. Consistent with other recent work, the article reports a generally significant but small effect of expenditure on school performance, but it also finds that the effect varies between specialist and non‐specialist schools, with the effect on the latter being larger. Further, the article identifies significant dynamics in the school improvement process, quantifies the long‐run effect of expenditure changes, suggests that spending effects increase with socio‐economic disadvantage, and quantifies absence effects. 相似文献

In this paper, we lay out a relational approach for indexing and retrieving photographs from a collection. The increase of digital image acquisition devices, combined with the growth of the World Wide Web, requires the development of information retrieval (IR) models and systems that provide fast access to images searched by users in databases. The aim of our work is to develop an IR model suited to images, integrating rich semantics for representing this visual data and user queries, which can also be applied to large corpora. 相似文献
