This research investigates the perceptions of refugee children, refugee parents and school staff regarding the positive adaptation of refugee children in a new social context and the effects on mental health and psychological well-being. This included an exploration of resilience and the role of risk and protective factors. Few studies have focused on views from a resilience perspective, and these have tended to use quantitative rather than qualitative measures. This mixed methods piece of “real world” research adopted a “what’s working well” perspective and explored the important voices of these children, parents and school staff. Staff, parent and child responses were triangulated to provide a rich picture of the potential protective factors operating within the school and family environment. Implications for practice are discussed.  相似文献

This paper presents research that examines the links between practitioners’ understanding of play and its relationship to learning, their pedagogic interactions with children and children’s own perceptions of their play. Previous research has shown a mismatch between practitioners’ understanding of play and their practice. This research identifies how differences in understanding of play, especially the role of the adult, by practitioners in two unrelated settings are associated with variation in pedagogic interactions emphasising choice and control. Furthermore, it is argued that these differences are reflected in differences in children’s use of the cue of adult presence as a defining feature of play and not-play activities.  相似文献

Background: computer software is widely used to support literacy learning. There are few randomised trials to support its effectiveness. Therefore, there is an urgent need to rigorously evaluate computer software that supports literacy learning.

Methods: we undertook a pragmatic randomised controlled trial among pupils aged 11–12 within a single state comprehensive school in the North of England. The pupils were randomised to receive 10 hours of literacy learning delivered via laptop computers or to act as controls. Both groups received normal literacy learning. A pre‐test and two post‐tests were given in spelling and literacy. The main pre‐defined outcome was improvements in spelling scores.

Results: 155 pupils were randomly allocated, 77 to the ICT group and 78 to control. Four pupils left the school before post‐testing and 25 pupils did not have both pre‐ and post‐test data. Therefore, 63 and 67 pupils were included in the main analysis for the ICT and control groups respectively. After adjusting for pre‐test scores there was a slight increase in spelling scores, associated with the ICT intervention, but this was not statistically significant (0.954, 95% confidence interval (CI) – 1.83 to 3.74, p = 0.50). For reading scores there was a statistically significant decrease associated with the ICT intervention (?2.33, 95% CI ?0.96 to ?3.71, p = 0.001).

Conclusions: we found no evidence of a statistically significant benefit on spelling outcomes using a computer program for literacy learning. For reading there seemed to be a reduction in reading scores associated with the use of the program. All new literacy software needs to be tested in a rigorous trial before it is used routinely in schools.  相似文献

Search effectiveness metrics are used to evaluate the quality of the answer lists returned by search services, usually based on a set of relevance judgments. One plausible way of calculating an effectiveness score for a system run is to compute the inner-product of the run’s relevance vector and a “utility” vector, where the ith element in the utility vector represents the relative benefit obtained by the user of the system if they encounter a relevant document at depth i in the ranking. This paper uses such a framework to examine the user behavior patterns—and hence utility weightings—that can be inferred from a web query log. We describe a process for extrapolating user observations from query log clickthroughs, and employ this user model to measure the quality of effectiveness weighting distributions. Our results show that for measures with static distributions (that is, utility weighting schemes for which the weight vector is independent of the relevance vector), the geometric weighting model employed in the rank-biased precision effectiveness metric offers the closest fit to the user observation model. In addition, using past TREC data as to indicate likelihood of relevance, we also show that the distributions employed in the BPref and MRR metrics are the best fit out of the measures for which static distributions do not exist.  相似文献

The Open and Distance Learning Association of Australia (ODLAA) has reached 25 years of age. This article traces the development of the Association over that period. It records the major changes that have taken place in the range and types of activities of the Association and explains the circumstances that led to those changes. It concludes by attempting to identify the principal challenges facing the Association in entering its second quarter century and proposes ways in which these challenges might be addressed.  相似文献
