为了解农村留守儿童社会情感能力的发展状况,对江苏省徐州市2个区进行了实地调查,并运用多元回归分析方法探讨了影响留守儿童社会情感发展的因素。结果表明:农村留守儿童的社会情感发展总体状况良好,但在人际交往、社区融入和亲社会行为方面存在一定问题。农村留守儿童社会情感的发展受到不同因素的影响,其中年级、亲子间沟通频率、教师行为和社区基础设施条件对留守儿童社会情感发展的各个方面都有影响,此外,成绩排名、班级团结度对留守儿童的人际交往有显著影响,亲子分离形式、是否为独生子女、社区关爱留守儿童活动的开展情况对留守儿童的社区融入有显著影响,性别、校园活动的丰富度对留守儿童的亲社会行为有显著影响。 相似文献

目的探讨学龄儿童行为问题与家庭环境因素的关系,为采取综合干预措施,减少儿童行为问题的发生提供流行病学依据。方法用Achenach儿童行为量表(CBCL)和Moss家庭环境量表,对佛山市535名8~12岁小学生进行问卷调查。结果535名儿童中78名至少有一种行为问题,总检出率为14.6%,男女性别检出率差异无统计学意义(P>0.05);非健全家庭的儿童行为问题发生率远远高于健全家庭(P<0.05);而不同父母文化水平的儿童之间,随着父母文化水平的降低,儿童行为问题的发生率呈上升趋势,检出率差异有统计学意义(P<0.05);行为问题组在矛盾性上得分明显高于对照组(P<0.01),而在亲密度、知识性、娱乐性、组织性上得分却明显低于对照组(P<0.05或0.01)。结论学龄儿童行为问题与家庭不健全、父母文化程度偏低、家庭矛盾性大、缺乏亲密度、情感表达不畅、组织娱乐性差有关,而与性别无关。 相似文献

The Devils Hole calcite vein contains a long-term climatic record, but requires accurate chronologic control for its interpretation. Mass-spectrometric U-series ages for samples from core DH-11 yielded (230)Th ages with precisions ranging from less than 1,000 years (2sigma) for samples younger than approximately 140 ka (thousands of years ago) to less than 50,000 years for the oldest samples ( approximately 566 ka). The (234)U/(238)U ages could be determined to a precision of approximately 20,000 years for all ages. Calcite accumulated continuously from 566 ka until approximately 60 ka at an average rate of 0.7 millimeter per 10(3) years. The precise agreement between replicte analyses and the concordance of the (230)Th/(238)U (234)U/(238)U ages for the oldest samples indicate that the DH-11 samples were closed systems and validate the dating technique in general. 相似文献

Role of genotype in the cycle of violence in maltreated children 总被引：1，自引：0，他引：1

We studied a large sample of male children from birth to adulthood to determine why some children who are maltreated grow up to develop antisocial behavior, whereas others do not. A functional polymorphism in the gene encoding the neurotransmitter-metabolizing enzyme monoamine oxidase A (MAOA) was found to moderate the effect of maltreatment. Maltreated children with a genotype conferring high levels of MAOA expression were less likely to develop antisocial problems. These findings may partly explain why not all victims of maltreatment grow up to victimize others, and they provide epidemiological evidence that genotypes can moderate children's sensitivity to environmental insults. 相似文献

Results from a longitudinal study of 2402 low-income families during the recent unprecedented era of welfare reform suggest that mothers' transitions off welfare and into employment are not associated with negative outcomes for preschoolers (ages 2 to 4 years) or young adolescents (ages 10 to 14 years). Indeed, no significant associations with mothers' welfare and employment transitions were found for preschoolers, and the dominant pattern was also of few statistically significant associations for adolescents. The associations that did occur provided slight evidence that mothers' entry into the labor force was related to improvements in adolescents' mental health, whereas exits from employment were linked with teenagers' increased behavior problems. 相似文献

马卡连柯是前苏联著名的教育家,他在晚年特别重视家庭道德教育问题。马卡连柯的家庭道德教育思想主要体现在:及早对儿童进行道德教育;父母必须以身作则、起表率作用;通过家庭生活制度培养孩子良好的行为习惯;建立良好的家风;从身边小事做起,重视细节;对孩子的教育要做到严慈、奖惩结合等。马卡连柯的家庭道德教育思想对我国未成年人道德建设有深刻的启示:重视家庭在未成年人道德建设中的基础性作用;发挥父母在家庭道德教育中的主导作用;为孩子营造一个良好的家庭道德氛围;未成年人道德建设要从娃娃抓起,及早实施;从基本道德素质抓起,从规范行为习惯做起,培养未成年人良好的道德品质和文明行为等。 相似文献

Early childhood programs have long been known to be beneficial to children from low-income backgrounds, but recent studies have cast doubt on their ability to substantially increase the rate of children's academic achievement. This Review examines research on the role of language in later reading, describes home and classroom factors that foster early language growth, and reviews research on preschool interventions. It argues that one reason interventions are not having as great an impact as desired is because they fail to substantially change the capacity of teachers to support children's language and associated conceptual knowledge. 相似文献

Improving cognitive ability in chronically deprived children 总被引：3，自引：0，他引：3
Beginning at different ages in their preschool years, groups of chronically undernourished children from Colombian families of low socioeconomic status participated in a program of treatment combining nutritional, health care, and educational features. By school age the gap in cognitive ability between the treated children and a group of privileged children in the same city had narrowed, the effect being greater the younger the children were when they entered the treatment program. The gains were still evident at the end of the first grade in primary school, a year after the experiment had ended. 相似文献

Preschool and primary grade children have the capacity to learn substantial mathematics, but many children lack opportunities to do so. Too many children not only start behind their more advantaged peers, but also begin a negative trajectory in mathematics. Interventions designed to facilitate their mathematical learning during ages 3 to 5 years have a strong positive effect on these children's lives for many years thereafter. 相似文献

The (230)Th ages and (234)U/(238)U ratios were determined for Barbados corals that grew during periods of high sea level within the last 200,000 years. The similarity of the initial (234)U/(238)U ratios of some of the corals to the modern marine value suggests that these samples are pristine and that the marine (234)U/(238)U ratio 83,000 and 200,000 years ago was within 2 per mil of the modern value. The accuracies of the (230)Th ages are evaluated on the basis of the (234)U/(238)U values and a model of the behavior of uranium and thorium isotopes during diagenesis. For the last three interglacial and two intervening interstadial periods, sea level peaked at or after peaks in summer insolation in the Northern Hemisphere. This overall pattern supports the idea that glacial-interglacial cycles are caused by changes in Earth's orbital geometry. The sea-level drop at the end of the penultimate interglacial, the last interglacial, and a subsequent interstadial period lagged behind the decrease in insolation by 5,000 to 10,000 years. 相似文献
