Research Findings: This study investigated the relationship between family socioeconomic status (SES) and children’s early attainment, and the roles of preschool attendance and executive function (EF) in this association. Participants were 3,331 children (1,584 girls) ranging in age from 36 to 71 months from Cambodia, Mongolia, and Vanuatu. Children’s language, literacy, and mathematics attainment and EF were assessed using the East Asia-Pacific Early Child Development Scales. Mothers reported on family demographics and children’s preschool experience. Results indicated significant associations between SES and academic attainment in all three countries. Further analysis showed that preschool attendance and EF were significant mediators of SES- related disparities in attainment, but differed by country. Both served as parallel and sequential mediators in the associations between SES and performance in language, literacy, and mathematics in Mongolia. However, only preschool attendance mediated the association of SES with literacy attainment in Cambodia, and only EF mediated that with children’s mathematics and language performance in Vanuatu. Although SES is substantially related with early achievement in these developing countries, our findings indicate that preschool attendance and EF may attenuate this relationship. Practice or Policy: Implications for the provision of early childhood education programs and public policy are discussed. 相似文献

Studies of the role of phonological representations in learning to read have almost exclusively focused on speech perception. In the current study, we examined links between sensorimotor control of speech, reading, and reading-related abilities. We studied two languages, English and Dutch, which vary in the regularity of their spelling-to-sound mappings. There were 236 American and Dutch children, 4 to 8 years old, who performed an altered auditory feedback task in which the first formant of the /?/ vowel was altered. A stronger response to altered feedback for literate relative to preliterate children was observed, and this was particularly the case for the Dutch children. Moreover, the magnitude of the responses was related to precursors of reading in preliterate children and to reading skill in literate children. We propose that these findings could be related to changes in children’s speech production skills that facilitate the integration of orthographic and phonemic information. 相似文献

Increasingly, learner motivation is implicated in student failure at universities. This has led to intense research into internal or external variables that might buoy resilience to failure. This research investigates the impact of strong cultural connectedness and strong belief systems on the academic buoyancy of international students studying at an Australian University. For this purpose, we surveyed 102 tertiary students at a Sydney university. Results demonstrate that, in the event of academic failure, students’ academic buoyancy remains high if they have support through strong cultural connections and from their belief systems. We further endeavored to identify if academic buoyancy was fed by intrinsic or extrinsic motivation. This research contributes to the understanding of the sources of strengths available to international students from primarily collective cultures studying overseas. There are implications for educational practice in terms of identifying students ‘at high risk’ if they are unable to draw strengths from cultural connections and belief systems. 相似文献

Discrete-scale invariance (DSI) is a phenomenon featuring intriguing log-periodicity that can be rarely observed in quantum systems. Here, we report the log-periodic quantum oscillations in the longitudinal magnetoresistivity (ρxx) and the Hall traces (ρyx) of HfTe5 crystals, which reveal the DSI in the transport-coefficients matrix. The oscillations in ρxx and ρyx show the consistent logB-periodicity with a phase shift. The finding of the logB oscillations in the Hall resistance supports the physical mechanism as a general quantum effect originating from the resonant scattering. Combined with theoretical simulations, we further clarify the origin of the log-periodic oscillations and the DSI in the topological materials. This work evidences the universality of the DSI in the Dirac materials and provides indispensable information for a full understanding of this novel phenomenon. 相似文献

The mission of universities today is not only to nurture experts in various professions, but also to cultivate lifelong autonomous learners. Independent learning and pedagogies that aim to foster learner autonomy have grown in importance over the past decade. However, the extent to which independent learning is successful in fostering autonomy has not been fully addressed; nor has a robust method for evaluating independent learning been available. The aim of this study was to evaluate the effectiveness of an independent learning component attached to a taught course by tracking changes in learners’ perceptions. Primary data were collected from course participants’ responses to two questionnaires. In total, 221 and 157 completed questionnaires were returned at the beginning and the end of the course, respectively, among which 95 paired responses enabled comparisons that revealed a general trend. In addition, a more focused investigation was carried out with nine participants who took part in semi-structured interviews and completed independent learning logs. The study, using a short-term longitudinal approach, revealed participants’ growing understanding of independent learning and its relevance to English language enhancement, particularly for those with no prior experience of any form of independent learning. 相似文献

澳门特区政府自2007~2008学年开始实施15年免费教育,至今已经实施5年了.为了解免费幼儿教育政策对澳门幼儿教育界的实际影响以及园(校)长、教师和家长对这一政策的态度,我们进行了相关研究,发现:(1)园(校)长、教师及家长大多对免费幼儿教育政策表示满意,其中家长满意度最高.(2)免费幼儿教育政策为澳门幼教发展带来了许多积极影响,负面影响较小.(3)免费幼儿教育政策对家长择园自主性的影响很小,对幼儿园课程与发展自主性的影响也很小,但会削弱入网私立幼儿园的行政自主性,在一定程度上增加了园(校)长和教师的工作压力.(4)政策的实施虽然对幼儿园收费标准的影响比较轻微,但是切实减轻了低收入家长的育儿负担.园(校)长、教师和家长均提出了改进免费幼儿教育政策的建议. 相似文献

In this paper, we present a framework that can process a user query for retrieval of information from documents of different properties across multiple domains, with specific application to patent laws and regulations. The framework has three basic components. The first component is ontology mapping and generation. What happens is that the keywords entered by users are mapped into a subset of relevant keywords. This step is performed by looking up those words in an ontology database. The second component is the joint and cross search in various document domains; in our case, they are patents and scientific publications. The last component is to modify the search results by applying user feedback statistics. The results of feedback will be saved as metadata for future uses.A case example is given to demonstrate how results from multiple domain searches can be combined using ontology and cross referencing. We use an example of well-known biotechnology patents on erythropoietin (EPO) and give detailed analysis on each document domain with this keyword. Relationships between each domain are demonstrated.A user feedback mechanism is also discussed in this paper. The ability to take user feedback into the framework is important. There is no doubt that domain knowledge from expert or experienced users could be a very good compliment to the proposed system. Both direct and indirect user feedbacks are discussed. 相似文献
