Data from the 1983–84 Israeli IEA (International Association for the Evaluation of Education Achievement) science study were used to explore gender-related differences (and their determinants) in the learning of science. The sample was composed of 1,934 ninth-grade students. The study involved several measures of science learning, ten attitudinal measures, and items and errors classification. Differences between boys and girls were observed in some measures of science performance–-particularly in the physical sciences, in items with lower estimates of “opportunity to learn,” and in specific kinds of errors. Gender-related differences were also observed in the predictive model of achievement, using science-specific affective measures. The discussion raises the cognitive and affective readiness of boys and girls for learning science. 相似文献

Hearing loss during the critical period for language acquisition restricts spoken language input. This input limitation, in turn, may hamper syntactic development. This study examined the comprehension, production, and repetition of Wh-questions in deaf or hard-of-hearing (DHH) children. The participants were 11 orally trained Hebrew-speaking children aged 9.1-12.4 with moderate-to-profound hearing loss from birth, who consistently used hearing aids or cochlear implants and who had difficulties understanding relative clauses. Experiment 1 tested the comprehension of Wh-questions using a picture selection task, comparing subject with object questions and who- with which-questions; Experiment 2 tested the production of subject and object who-questions using an elicitation task; and Experiment 3 tested the repetition of Wh-questions and other structures derived by Wh-movement. All the DHH participants showed difficulty in the comprehension, production, and repetition of object questions, and their performance was significantly below that of hearing children. In contrast, they repeated embedded sentences without movement well, indicating that their deficit is in syntactic movement rather than embedding or the CP node in the syntactic tree. The results provide additional evidence that DHH children have difficulties with Wh-movement and emphasize that Wh-questions, which are crucial for communication, can be severely impaired in these children. 相似文献

The current study examined whether parental and contextual risk factors contribute to mothers' and fathers' differential treatment (MDT/FDT) when accounting for sibling dyad characteristics. Also explored was whether family type (single mothers vs. 2 parents) moderated the links between the parental and contextual correlates and MDT. One hundred and seventy-two families with older (M= 7.4 years) and younger (M= 5.2 years) siblings were studied. Parents and children reported about the parent-child relationship, and parents reported about the children's characteristics, their own psychological resources, and contextual factors. Controlling for sibling dyad characteristics, FDT was predicted most consistently by household chaos. Furthermore, single mothers were not at risk per se for using more MDT but only when coupled with high maternal anger. 相似文献

Mother–Child Interaction: Links Between Mother and Child Frontal Electroencephalograph Asymmetry and Negative Behavior

下载免费PDF全文 It is well accepted that parent–child interactions are bidirectional by nature, yet not much is known about the psychophysiological activity underlying these interactions. This study examined, during a parent–child interaction, how a child's negativity statistically predicted maternal frontal electroencephalograph (EEG) asymmetry and how a mother's negativity statistically predicted child frontal EEG asymmetry. Thirty‐four mother–child dyads participated in the study. Maternal and child behaviors and physiology were measured during a puzzle task. Results indicated that mothers whose children exhibited more challenging behaviors during the dyadic interaction displayed more right (relative to left) asymmetry, as did children whose mothers were high in negativity during the interaction. These findings suggest that mothers and children react to each other's signals not only behaviorally but also physiologically. 相似文献
