The friendship nominations of 40 standard 2 children (aged 8‐10 years), 20 in multi‐level and 20 in single‐level classes, were examined. Children nominated friends, including age and whether they went to the same school, by writing down friends’ names in class and stating them verbally in an interview situation. Children were asked in the interview about their best friends, their views on cross‐sex and cross‐age friendships, and what friends do together. Results showed that 65% of interview‐nominated and 56% of class‐nominated friends were of the same age, while 91% of interview‐nominated and 81% of class‐nominated friends were of the same sex. Children from multi‐level classes had significantly more different aged friends on class and interview measures, and more different sexed friends on the class measure, than children from single‐level classes. Children's out‐of‐school friendships were more likely to be with cross‐age or cross‐sex children than were their in‐school friendships. Children tended to give positive reasons for playing with different aged friends, such as learning from more skilled older friends and feeling responsible when nurturing younger children, but few positive reasons were given for playing with opposite sex friends. Most children expressed a lack of interest or even a dislike for the activities and characteristics of the opposite sex.  相似文献

This study replicates research on the efficacy of a repeated reading intervention with word-level instruction for students in Grades 2 and 3 with low to moderate fluency skills, examines differences between treatment implementers, and tests unique contributions of treatment-related variables on outcomes. Students from 13 schools were randomly assigned to dyads; dyads were randomly assigned to treatment or control conditions. Schools were matched into treatment implementer groups (teachers or paraeducators) at study onset. Tutoring occurred during school hours for 15 weeks (M = 25.5 hr). Multilevel model results showed treatment students (n = 98) gained more than controls (n = 104) on measures of letter-sound knowledge (d = .41), fluency (d = .37–.38), and comprehension (d = .30–.31); students tutored by teachers gained more than their paraeducator-tutored peers on word reading and fluency. Finally, dyads tutored with greater fidelity gained more in word reading and fluency; dyads that read more complex words in their texts gained less on letter-sounds, fluency, and comprehension.  相似文献

Milk provides not only the building blocks for somatic development but also the hormonal signals that contribute to the biopsychological organization of the infant. Among mammals, glucocorticoids (GCs) in mother's milk have been associated with infant temperament. This study extended prior work to investigate rhesus monkey (Macaca mulatta) mother–infant dyads (N = 34) from birth through 8 months postpartum. Regression analysis revealed that cortisol concentrations in milk during the neonatal period predicted impulsivity on a cognitive task, but not global social behaviors, months later. During this time period, sex‐differentiated social behavior emerged. For female infants, milk cortisol concentrations predicted total frequency of play. Collectively, these findings support and extend the “lactational programming” hypothesis on the impact of maternal‐origin hormones ingested via milk.  相似文献

In the hit BBC TV drama Life on Mars Sam Tyler had an accident and woke up in 1973. Is he mad, in a coma or actually back in time? As the drama unfolds he experiences a world without performance audits but also one without the safeguards for arrest, detention and the interviewing of suspects mandated by the Police and Criminal Evidence Act (1984). The acclaimed series has led to flights of nostalgia, not least for a world in which police could get on with ‘real policing’ without ‘unnecessary’ paperwork. In this article, we will metaphorically go back in time to contemporary and historical practices of headship in English schools. If a headteacher from 2009 were to wake up in 1973 what would they understand about their work, what would be the same, what would be different? What taken‐for‐granted current practices might get them into trouble, what might frustrate them – and what might delight them that they would bring back to the current job if they could? Mobilising Bourdieu’s thinking tools, we will examine these questions through an analysis of published and unpublished texts produced by heads about their work.  相似文献

Relations between self-reported parental reactions to children's negative emotions (PNRs) and children's socially appropriate/problem behavior and negative emotionality were examined longitudinally. Evidence was consistent with the conclusion that relations between children's externalizing (but not internalizing) emotion and parental punitive reactions to children's negative emotions are bidirectional. Reports of PNRs generally were correlated with low quality of social functioning. In structural models, mother-reported problem behavior at ages 10-12 was at least marginally predicted from mother-reported problem behavior, children's regulation, and parental punitive or distress reactions. Moreover, parental distress and punitive reactions at ages 6-8 predicted reports of children's regulation at ages 8-10, and regulation predicted parental punitive reactions at ages 10-12. Father reports of problem behavior at ages 10-12 were predicted by earlier problem behavior and parental distress or punitive reactions; some of the relations between regulation and parental reactions were similar to those in the models for mother-reported problem behavior. Parental perceptions of their reactions were substantially correlated over 6 years. Some nonsupportive reactions declined in the early to mid-school years, but all increased into late childhood/early adolescence.  相似文献

A view of science as a culturally‐mediated way of thinking and knowing suggests that learning can be defined as engagement with scientific practices. How students engage in school science is influenced by whether and how students view themselves and whether or not they are the kind of person who engages in science. It is therefore crucial to understand students' identities and how they do or do not overlap with school science identities. In this paper, we describe four middle school African American girls' engagement with science. They were selected in the 7th grade because they expressed a fondness for science in school or because they had science‐related hobbies outside of school. The data were collected from the following sources: interviews of students, their parents and their teachers; observations in science classes; journal writing; and focus groups. These girls' stories provide us with a better understanding of the variety of ways girls choose to engage in science and how this engagement is shaped by their views of what kind of girl they are. © 2000 John Wiley & Sons, Inc.
