采用“中国学校课程教学调查项目”中1811名八年级学生及其家长作为样本进行调查,探讨家庭社会经济地位与数学成绩的关系,考察亲子沟通和学业自我效能感的作用机制。结果显示:(1)家庭社会经济地位显著正向影响数学成绩;(2)亲子沟通、学业自我效能感在家庭社会经济地位与数学成绩之间起部分中介作用;(3)亲子沟通、学业自我效能感在家庭社会经济地位与数学成绩之间具有链式中介作用。 相似文献

Language abilities in early childhood show stability over time and play an important role in the development of other cognitive processes. Identifying modifiable environmental risk factors is important to informing prevention and early intervention efforts. Maternal verbal ability has been previously linked to child verbal ability. The current study examined whether maternal and child verbal abilities were linked indirectly through early childhood maternal responsiveness. Data come from a longitudinal birth cohort study. Participants included 133 mothers and their children recruited from maternity wards shortly after birth. Maternal verbal ability was measured using the Vocabulary subtest from the Wechsler Abbreviated Scale of Intelligence, Second Edition (child age 8 months). Child verbal ability was assessed using the Peabody Picture Vocabulary Test (36 months). A latent maternal responsiveness variable was estimated using three developmentally sensitive indicators; one during infancy (child age 8 months) and two when children were 36 months. Results of a structural equation model indicated a significant indirect effect from maternal verbal abilities to child verbal abilities through maternal responsiveness. This indirect path was significant even after inclusion of another indirect path from maternal executive functioning to child verbal ability through maternal responsiveness (which was not significant). Future studies will benefit from experimental, genetically sensitive and/or cross‐lagged designs to allow for conclusions related to directionality and causality. This body of research has implications for the study of the intergenerational transmission of verbal abilities and associated skills, behaviours and adaptive outcomes. 相似文献

以498名高中生为研究对象,通过问卷调查法探讨高中生的自我妨碍与学习投入的关系,并考察学业浮力的中介作用以及父母支持的调节作用。测量工具包括自我妨碍量表、学习投入量表、学业浮力量表和父母自主支持量表。结果表明:(1)自我妨碍对学习投入有显著负向预测作用;(2)学业浮力在自我妨碍和学习投入的关系中起部分中介作用;(3)自我妨碍和学习投入的关系受到父母支持的调节。与低父母支持相比,在高父母支持的学生中,自我妨碍对学习投入有更强的负向预测作用。 相似文献

以756名中学生为研究对象,对学业投入、学业成就、同伴团体进行追踪测量,探讨青少年同伴团体的学业投入及学业成就是否存在同伴选择与同伴影响效应。结果表明:(1)在1年的追踪时间中,青少年学业投入的发展呈下降趋势,初始水平与下降速度负相关,学业成就的发展呈上升趋势,初始水平与上升速度无显著相关;(2)学业投入与学业成就存在同伴选择效应,青少年倾向选择与自己学业投入及学业成就相似的个体构建同伴团体;(3)青少年的学业投入及学业成就与同伴逐渐趋近相似,即同伴影响效应显著。 相似文献

为探讨家庭功能对青少年早期外化问题行为的影响,以及心理韧性和性别在二者关系中的作用机制,采用家庭功能量表、心理韧性量表和青少年外化问题行为量表对1284名初一学生进行测查。结果显示:(1)家庭功能显著负向预测青少年外化问题行为。(2)心理韧性在家庭功能和青少年外化问题行为中起部分中介作用,即家庭功能可以通过心理韧性间接影响青少年外化问题行为。(3)家庭功能对青少年外化问题行为中介过程的前半条路径和直接路径受到性别调节,具体而言,相比于男生,在女生群体中,家庭功能对心理韧性的影响更大;相比于女生,在男生群体中,家庭功能对外化问题行为的影响更大。 相似文献

For scientific knowledge to be trustworthy, it needs to be dissociated from material interests. Disinterested research also
performs other important non-instrumental roles. In particular, academic science has traditionally provided society with reliable,
imaginative public knowledge and independent, self-critical expertise. But this type of science is not compatible with the
practice of instrumental research, which is typically proprietary, prosaic, pragmatic and partisan. With ever-increasing dependence
on commercial or state funding, all modes of knowledge production are merging into a new, ‘post-academic’ research culture
which is dominated by utilitarian goals. Growing concern about conflicts of interest is thus a symptom of deep-seated malaise
in science and medicine.
An expanded version of this paper was presented at an International Conference on “Conflict of Interest and its Significance
in Science and Medicine” held in Warsaw, Poland on 5–6 April, 2002. 相似文献

The purpose of this review was to report on the effectiveness and focus of academic self-management interventions for children and adolescents with emotional and behavioral disorders. Twenty-two studies published in 20 articles and involving 78 participants met inclusionary criteria. The overall mean effect size (ES) across those studies was 1.80 (range –0.46 to 3.00), indicating effects were generally large in magnitude and educationally meaningful. Self-monitoring interventions were the predominant type of self-management technique used by researchers. The mean ES for intervention types were self-evaluation (1.13), self-monitoring (1.90), strategy instruction techniques (1.75), self-instruction techniques (2.71), and multiple-component interventions (2.11). Interventions targeted improvement in math calculation skills more than any other area. The mean ES by academic area were math interventions (1.97), writing (1.13), reading (2.28), and social studies (2.66). There was evidence to support a claim of the generalization and maintenance of findings. Implications, limitations, and areas for future research are discussed. 相似文献
