This study examined the role of instruction for spelling performance and spelling consciousness in the Dutch language. Spelling consciousness is the ability to reflect on one's spelling and correct errors. A sample of 115 third-grade spellers was assigned to a strategy-instruction, strategic-monitoring, self-monitoring, or control condition representing different types of metacognitive aspects. The results showed that students in all three training conditions made more progress in both spelling performance and spelling consciousness than students in the control condition. With respect to spelling consciousness, only students in the strategy-instruction condition made significant improvement between pretest and posttest. Students made more progress in spelling performance on regular words than on loan words. Students in all four conditions became more accurate at assessing which words they could spell correctly. Students in the control condition more frequently overestimated their spelling ability. 相似文献

This paper describes some features of a study which compares and contrasts mothers’ perceptions of their family life in three different family environments, those without a child with disability and those families who live with a child with an intellectual or physical disability. All families have children in the middle childhood period allowing the mothers to reflect on earlier experiences and changes in their family life. Mothers’ psychological characteristics are explored in terms of the coping resources they utilise when meeting stressful life situations in their family and how their personal resilience and vulnerability is related to these individual coping resources. 相似文献

This study leverages naturally occurring lotteries for oversubscribed Boston Public Schools prekindergarten program sites between 2007 and 2011, for 3,182 children (M = 4.5 years old) to estimate the impacts of winning a first choice lottery and enrolling in Boston prekindergarten versus losing a first choice lottery and not enrolling on children’s enrollment and persistence in district schools, grade retention, special education placement, and third-grade test scores. There are large effects on enrollment and persistence, but no effects on other examined outcomes for this subsample. Importantly, children who competed for oversubscribed seats were not representative of all appliers and almost all control-group children attended center-based preschool. Findings contribute to the larger evidence base and raise important considerations for future prekindergarten lottery-based studies. 相似文献

Numerous studies suggest an association between language and executive function (EF), but evidence of a developmental relationship remains inconclusive. Data were collected from 75 deaf/hard-of-hearing (DHH) children and 82 hearing age-matched controls. Children were 6–11 years old at first time of testing and completed a battery of nonverbal EF tasks and a test of expressive vocabulary. These tasks were completed again 2 years later. Both groups improved their scores on all tasks over this period. DHH children performed significantly less well than hearing peers on some EF tasks and the vocabulary test at both time points. Cross-lagged panel models showed that vocabulary at Time 1 predicted change in EF scores for both DHH and hearing children but not the reverse. 相似文献

There have been many practical obstacles for teachers to implement evidence-based educational technology, especially in STEM classrooms. By implementing learning principles related to Cognitive Load Theory, we developed an innovative Technology-Assisted Guided Learning (TAGL) approach and its web-based instructional tool, combining expertise from educational research and best teaching practices to enhance guided student-centered learning in chemistry. A total of 185 community college students were randomly assigned to learn stoichiometry through either TAGL or one of two active control interventions, traditional direct instruction and Khan Academy, a widely used web learning platform. We found that the TAGL group significantly outperformed both active control groups immediately after instruction, and furthermore, despite the fact that all groups received additional instruction in stoichiometry, the beneficial effects of TAGL compared to the control groups were maintained a month later. Notably, TAGL was able to eliminate the achievement gap between students with low prior knowledge and students with high prior knowledge. Furthermore, prior-knowledge activation was found to be especially beneficial for students with low prior knowledge. Our work contributes to existing research in learning theories and provides new insight toward the development of more effective and adaptive instructional designs. By translating research into practice, this study demonstrates the great potential of using innovative computer-based technology to improve student learning for all. 相似文献

Reduction of water evaporation in polymerase chain reaction microfluidic devices based on oscillating-flow 总被引:1,自引:0,他引:1

Producing polymeric or hybrid microfluidic devices operating at high temperatures with reduced or no water evaporation is a challenge for many on-chip applications including polymerase chain reaction (PCR). We study sample evaporation in polymeric and hybrid devices, realized by glass microchannels for avoiding water diffusion toward the elastomer used for chip fabrication. The method dramatically reduces water evaporation in PCR devices that are found to exhibit optimal stability and effective operation under oscillating-flow. This approach maintains the flexibility, ease of fabrication, and low cost of disposable chips, and can be extended to other high-temperature microfluidic biochemical reactors. 相似文献

In this article, I draw on post-structural and feminist epistemologies to analyse interview data from two prospective teachers
on a primary education degree. Specifically I use Foucauldian critical discourse analysis to discuss the competing discourses
of the masculine mathematician and the feminine primary school teacher. The initial purpose of the article is to deconstruct
the themes of control, choice and confidence, which I argue are prevalent within mathematical discourses within our current
neoliberal society. A further aim of the article is to explore the representation of discourse and data within educational
texts, which I do by experimenting with the language used throughout. 相似文献

The acquisition of reading skill was studied in 503 Italian children in first to eighth grade using a task that required reading
of lists of words and non-words. Analysis of the metric characteristics of the measures indicated that reading speed but not
accuracy was normally distributed across all ages considered. The role of specific effects (length, word frequency, and lexicality)
versus global factors in reading speed was examined using the Rate–Amount Model (RAM). A global processing factor accounted
for a large portion of the variance. Specific influences of length, frequency, and lexicality were detected in different periods
of development over and above the global processing factor. Length modulated performance at early stages of learning and progressively
less later on; in the case of non-words, the effect of length was large but did not change as a function of grade. The lexicality effect, present at all ages for high frequency words and by third grade for low frequency words increased with reading practice
indicating a progressive differentiation in the ability to read words and non-words. Finally, the effect of word frequency
was highest in third grade and then decreased. These findings are discussed in terms of their relevance for reading acquisition
in a language with transparent orthography and their implications for evaluating developmental reading deficits. Overall,
it is proposed that RAM is a useful tool for disentangling the role of specific versus global factors in reading development. 相似文献
