This study investigated for the first time several characteristics of underachievement in a large sample of Hong Kong elementary schoolchildren. More males were identified as underachievers than females, but the ratio was substantially less than the two-to-one rate typically found in the American literature. The stability and persistence of underachievement increased during the elementary school years, and the stability of underachievement tended to be higher in subject matter that was relatively more difficult, which varied with gender. Underachievement became more specific to particular academic subjects rather than more general across the elementary grades. Parents and teachers, but not the children themselves, perceived that underachievers were more capable than same-grade nonunderachievers (who score lower on ability tests), although this awareness is more likely directed at male than female underachievers, which has been observed in other samples. In grades 1-4, teachers provided extra mentoring, communications, and support to underachievers. Thereafter, underachievers became more disruptive, impatient, and aggressive in school and perhaps at home. At that point, teachers became less supportive, offered less extra mentoring, and applied greater behavioral control over underachievers. Underachieving children also perceived that their parents became less supportive and used more discipline in grades 5-6 relative to grades 3-4. These correlates of underachievement suggests the existence of a syndrome of underachievement that separates underachievers from children who have the same grades but lower mental ability.  相似文献

OBJECTIVE: Seeking to discern optimal programmatic strategies and inform the "universal versus targeted" debate in early home visitation services to prevent physical child abuse and neglect, a meta-analysis was conducted examining enrollment approaches in early home visitation studies and their reported outcomes. METHOD: Quantitative meta-analytic techniques were used to compare effect sizes from 19 controlled outcome studies across screening-based and population-based enrollment strategies. Effect sizes were calculated on protective services data and on child maltreatment related measures of parenting. RESULTS: On protective services report data, population-based studies reported a weighted mean effect size attributable to early home visitation of +3.72%, in comparison to -.07% for screening-based studies. On child maltreatment related measures of parenting, population-based studies reported a weighted mean effect size (r) attributable to early home visitation of +.092, in comparison to +.020 for screening-based studies. CONCLUSIONS: The findings indicate that population-based enrollment strategies appear favorable to screening-based ones in early home visitation programs seeking to prevent physical child abuse and neglect. It may be that psychosocial risk screens serve to enroll higher proportions of families for which early home visitation services are less likely to leverage change, and to exacerbate a mismatch between early home visitation service aims and family needs.  相似文献

Using latent variable structural equation modeling, a family economic stress model that links economic well-being to child well-being in an ethnically diverse, low-income sample of 419 elementary school-age children was evaluated. The sample was 57% African American and 28% Hispanic, and most families were headed by single mothers. The results provided support for the position that family process is a critical mediator of the effects of economic hardship on children's social adjustment. Lower levels of economic well-being, and the corollary elevated perceptions of economic pressure indirectly affected parenting behavior through an adverse impact on parental psychological well-being. Distressed parents reported feeling less effective and capable in disciplinary interactions with their child and were observed to be less affectionate in parent-child interactions. In turn, less than optimal parenting predicted lower teacher ratings of children's positive social behavior and higher ratings of behavior problems. Multiple-group analyses revealed that the pathways by which economic hardship influences children's behavior appear to operate similarly for boys and girls, and for African American and Hispanic families.  相似文献

Memorial University has been active in the use of educational media since its creation, and operates a public channel, initially broadcast through CBC but now on cable distribution. The author discusses the changes that have occurred over the past few years in the role of television there and describes the interactive element called PLA YBA CK, through which viewers can now access any of 1000 programmes by a telephone call to the control room. The reader is invited to consider the changes in philosophy such developments inevitably entail.  相似文献

It is widely agreed that children recognize their first words in a different way than they later decode. One hypothesis is that sight words are recognized as wholes, another that they are recognized by parts. Two experiments were devised to compare these hypotheses. In one, children were taught a sight word accompanied by a salient extraneous cue and then tested for recognition of the word and the cue. In the other, children were taught sight words, then tested for recognition of each half of the word. The children were found to recognize the cue but not the word; they recognized one half of the word but not the other. The results support the idea that first words are recognized by selective association.  相似文献
