One popular view of student achievement is that the quality of teaching students receive plays an important part in whether or not they do well at school. In this article we draw attention to ‘context’ as a complementary explanation, particularly regarding achievement differences between students from different socio‐economic backgrounds. In making these observations, we utilise data from one Australian secondary school located in an economically depressed rural community. Drawing on the insights of Bourdieu, our focus is on the broader social and economic influences that can adversely position students and schools, as well as work to inform the institutional stance that schools take in relation to their students. 相似文献

ABSTRACTChildren’s positive perceived motor competence (PMC) provides motivation for physical activity. Theoretically young children (<8 years) have inflated PMC but as children cognitively develop, perceptions are hypothesized to decrease. This study investigated strength of PMC association over time, whether any change was negative (i.e. PMC decreased) and sex differences. A total of 198 children participated, 88 (44.4%) girls and 110 (55.6%) boys, aged 8.37–11.3 years at time point one (T1). Test–retest reliability using intraclass correlation was moderate for locomotor and moderate-to-good for object control perception. Hierarchical regression analysis showed PMC at T1 positively predicted significant variance one year later (T2) for locomotor (23.1%) and object control skill (5 items: 37.7%; 7 items: 39.9%). Whilst boys and girls differed on perception level there was no interaction between PMC and sex. Incongruent with previous theoretical perspectives this study identified stability in children’s PMC across an important developmental period. 相似文献

Hybrid stone consolidants prepared from tetraethoxysilane (TEOS) and α,ω-hydroxyl-terminated polydimethylsiloxane (PDMS-OH) have been considered as one of the most promising approaches to improve the effectiveness of traditional alkoxysilane-based formulations. They have emerged as response to the negative reports commonly found in the literature: the resulting silica gel phase (SiO2) tends to develop fractures and fissures inside the stone as the gel shrinks during the drying stage. In this work, we employed SEM, solid-state 29Si NMR spectroscopy and compressive tests to characterize SiO2-PDMS hybrid gels. We report the morphological characteristics exhibited by gels prepared in vitro and in situ. It was found an appreciable reduction of gel fracture for hybrids prepared from 5% w/w of PDMS. As TEOS polycondenses, PDMS-OH is chemically incorporated into the gel matrix via Si-O-Si bonds. The inclusion of these elastic chains provides the necessary flexibility to resist the stress imposed by capillary pressure. Additionally, an important hydrophobic character is imparted to the stone. 相似文献

In this article, we analyse the attitude toward school that successful students of post-compulsory education possess. We understand school success as a concept that takes into account academic results, but also includes the desire to continue studying, while often overcoming difficulties at school. The data were taken from a sample of 26 students (12 girls and 14 boys) enrolled in Baccalaureate studies and vocational training. It was collected from detailed interviews, context questionnaires and the photolanguage technique. The results show that students are clearly committed to education, which takes the form of positive attitudes toward schoolwork and tasks (perseverance, effort, respect for the rules) and to the development of a defined life project and a high-level of satisfaction with their education. Baccalaureate students, particularly girls, more clearly express these traits. 相似文献

While extant research discusses how niche innovations develop in protected market niches and trigger regime shifts along sustainability transition pathways, we know less about the direct role of different niche actors as competitors in affecting regime incumbents’ investments in niche innovations. This study addresses this gap and builds on Strategic Niche Management and the Multi-level Perspective to distinguish two different niche actors: prosumers on the demand-side applying a niche innovation in a disruptive way to regime incumbents’ business model, and new entrants on the supply-side applying the niche innovation symbiotically with the regime. We examine incumbent responses to these different niche actors in different competitive and policy environments. Studying the United States’ electricity industry's sustainability transition toward solar from 2010-2017, we find that as more niche actors enter, regime incumbents are more likely to invest in the niche innovation, but the effect is influenced by policy and competitiveness of the environment. In competitive environments, incumbents are more likely to respond to disruptive niche actors (prosumers), while in traditional monopoly-like markets they are more likely to respond to symbiotic niche actors. We also find that the prosumer effect is stronger when the time that policies in support of the niche innovation have existed is shorter, indicating a potential substituting relationship of niche actors and policy. Our work contributes to the extant literature by demonstrating that the interplay between different niche actors needs to be understood within the context of policy, and that considering policy without accounting for the competitive environment may omit an important aspect of how regime actors become active participants in sustainability transitions. 相似文献
