Reading difficulties have reached a prevalence of 3–10% in school-age children. Those who present these difficulties avoid reading and benefit very little from school-based learning opportunities, resulting in maladjustments, dropping out of school and having to repeat grades. Presented here are the results of an intervention based on a computer game intended for explicit phonic training in first-grade school children at risk of possessing reading difficulties. Fifty-six children from a low socioeconomic status (SES) and 31 children from a high socioeconomic status, divided into two groups (control and experimental), participated in the study. After the intervention, participants from the low-SES experimental group had enhanced their skills regarding letter sound recognition, whereas the high-SES experimental group had improved their naming speed. The results are discussed in light of the impact of interventions based on computer games and of the importance of the development of sublexical skills in children at risk of manifesting reading difficulties in transparent orthographies. 相似文献

Data envelopment analysis (DEA) was used to assess the technical efficiency of special district libraries in the United States with respect to three cost-related outputs: operating cost per hour, program costs per visit, and program costs per attendance. A set of discretionary and non-discretionary inputs were used to obtain the technical efficiency scores of 999 special district libraries. The DEA input-oriented analysis shows that 30% of the libraries were technically efficient with respect to the use of the inputs to achieve their level of operating costs in 2015. The DEA analysis also shows that inefficient libraries need to make proportional reductions in the level of discretionary inputs to become technically efficient. 相似文献

The present study investigated relationships among false belief, emotion understanding, and social skills with 60 3- to 5-year-olds (29 boys, 31girls) from Head Start and two other preschools. Children completed language, false belief, and emotion understanding measures; parents and teachers evaluated children's social skills. Children's false belief performance related to their understanding of their friend's emotions and to teacher's ratings of social skills. Aspects of emotion understanding related to social skills. Head Start (n =30) and non-Head Start preschoolers (n = 30) performed similarly on social skills and emotion understanding measures, however, non-Head Start children performed significantly better on false belief tasks than Head Start children. Results demonstrate the importance of including diverse groups of children in studies of social cognition. 相似文献

Through interviews with migrants and migrant aid-workers at a shelter in the border town of Nogales, Mexico, we examine how undocumented migrants are seeking, acquiring, understanding, and using information prior to, and during, migration across the United States–Mexico border. Our study examines migrants' perceptions of humanitarian service and the use of so-called “border disturbance technologies” by activists to help prevent the death of migrants in the desert, finding that migrants appreciate water-caching efforts but generally distrust technologies they feel could subject them to surveillance by border agents. Exploratory in nature and based on a small sample, our findings are not necessarily representative of the broader population, but provide rich evidence of the prevalence of word-of-mouth information seeking and use of cell phones over other information technologies, and explore the ambivalent nature of information technology use in the vulnerable setting of life at the border. In particular, we find that mobile phones help migrants meet their communication needs, but also increase their exposure to crime and abuse. 相似文献
