Recent Government policy in England and Wales on Information and Communication Technology (ICT) in schools is heavily influenced by a series of non‐randomised controlled studies. The evidence from these evaluations is equivocal with respect to the effect of ICT on literacy. In order to ascertain whether there is any effect of ICT on one small area of literacy, spelling, a systematic review of all randomised controlled trials (RCTs) was undertaken. Relevant electronic databases (including BEI, ERIC, Web of Science, PsycINFO, The Cochrane Library) were searched. Seven relevant RCTs were identified and included in the review. When six of the seven studies were pooled in a meta‐analysis there was an effect, not statistically significant, in favour of computer interventions (Effect size = 0.37, 95% confidence interval =–0.02 to 0.77, p = 0.06). Sensitivity and sub‐group analyses of the results did not materially alter findings. This review suggests that the teaching of spelling by using computer software may be as effective as conventional teaching of spelling, although the possibility of computer‐taught spelling being inferior or superior cannot be confidently excluded due to the relatively small sample sizes of the identified studies. Ideally, large pragmatic randomised controlled trials need to be undertaken. 相似文献

Randomised controlled trials (RCTs) are often seen as the 'gold standard' of evaluative research. However, whilst randomisation will ensure comparable groups, trials are still vulnerable to a range of biases that can undermine their internal validity. In this paper we describe a number of common threats to the internal validity of RCTs and methods of countering them. We highlight a number of examples from randomised trials in education and health care where problems of execution and analysis of the RCT has undermined their internal validity. However, awareness of these potential biases can lead to careful planning to avoid or reduce their occurrence. If good quality randomised trials are to inform policy and practice in education then rigorous trials need to be designed that are the least susceptible to threats to their validity. 相似文献

The librarians at four hospital libraries describe the electronic reference service, "Ask A Librarian," offered at their institutions. The hospitals are vastly different in size and in number of library staff, and offer the "Ask A Librarian" service to different clientele. The article illustrates that both large hospitals with a large library staff and small hospitals with a solo librarian and some volunteers can offer this type of service. 相似文献

This study offers an insight into the experiences of three newly qualified English primary teachers and their pupils as they sought to develop dialogic teaching in lessons. It draws upon a range of literature from the field of classroom talk, with a particular focus on the work of Robin Alexander to underpin teacher/researcher professional discussion and analysis of periodic video recordings of talk in these classrooms. Supplemented by teacher interviews, the research examines the extent to which a dialogic approach to teacher professional development might facilitate teacher self‐evaluation as a means of developing a more dialogic classroom. In doing so, it seeks to exemplify key talk moves (dialogic bids) that these teachers used to open up dialogic spaces in lessons. The research concludes that raising teacher awareness of such talk moves through professional discussion and reflection upon teaching can provide teachers with a metacognitive resource for talking about and furthering dialogic teaching practices. 相似文献

There are lots of opportunities in a classroom day for the development of literacy. Reading aloud to children is one of the most important of these. Carole Silva here reminds us of the potential of this activity and gives several practical suggestions for working with children. 相似文献

Recruitment is known to be a challenge for intervention programs targeting youths, including sports programs. Following the popularity of the Alter-Action program of the Montreal-based organization DesÉquilibres, we wanted to understand the motivations and barriers to youths' recruitment in this voluntary sports community program. A qualitative methodology was favored. We conducted 27 semi-structured interviews (n = 27) with participants, 5 (n = 5) with the partners, and we carried out a focus group with 5 (n = 5) of the organization's service practitioners. We also conducted a participant observation with youth cohorts and during preparatory meetings. Five factors influencing recruitment emerged: (1) socialization/belonging; (2) training/physical aspects; (3) ‘extraordinary’ dimension; (4) practicality of the program; and (5) social influences. Four key elements thus appear important to consider when promoting the recruitment of youths in voluntary community programs: (1) favoring social interactions; (2) insisting on the specific and beneficial elements of the program; (3) allowing youths to experiment a trial period; and (4) including testimonies of former participants in the information session. Further recommendations for psychosocial intervention programs targeting youths are discussed in this article. 相似文献

The interdisciplinary approach to family diagnosis and treatment of child abuse often begins in the hospital. The tone established at this time has crucial implications for the treatment program following discharge from the hospital. There is, however, a paucity of information in the literature regarding the best utilization of this critical phase of treatment. Often this period is viewed as a time for assessment, diagnosis and treatment of the physical injuries while neglecting to recognize and utilize the potential for planned therapeutic intervention during the hospital stay. This paper identifies methods and interventions in implementing a treatment plan particular to this phase of the over-all treatment of the child and family. 相似文献
