Data on perinatal and early childhood somatic and psychological risk factors of a random sample of children were gathered in early to middle childhood and employed to examine the long-term risk of emotional and behavioral problems of late childhood and adolescence. 3 issues were addressed: First, can syndromic specificity of such effects be identified on scaled and diagnostic measures of syndromes? Second, are these effects attributable to excess risk of low-income children for both perinatal and later childhood problems? Third, are the intervening mechanisms identifiable as intellectual impairment, vulnerability to poor health, poor maternal caretaking, maternal rejection, or maternal stress associated with marital problems? Findings indicated that elevated risk was present for all syndromes, both at the scale level and at the diagnostic level. None of the examined intervening mechanisms fully accounted for the effects of early risks.  相似文献

The language competence and reading comprehension of 406 7‐year‐old children are examined in the research discussed in this article. The children were tested using comparative tests as part of an international project conducted in 14 countries and sponsored by the IEA and the High Scope Research Foundation in Ypsilanti, USA. The discussion here relates only to a part of this wider research and focuses upon the aims and contents of Polish language teaching in grades I—III of the Polish primary school.  相似文献

The teachers' role in the integration of science and technology studies within the recent educational reform in Israeli junior high schools was addressed within a case study. Eight science teachers and three technology teachers participated in in‐service training courses and received individual tutoring. Data were obtained through school visits, interviews with management, teachers, and tutors. Pupils' performance on a science‐technology project was assessed by an achievement test and a questionnaire. Science teachers preferred to extend their content knowledge and didactic skills in science. Technology teachers lacked basic scientific knowledge. A realistic aim is to expose the science teacher to the field of technology, and the technology teacher to the realm of science, to the extent that will enable him or her to cooperate with the teacher in the parallel domain, rather than train a teacher to teach both. © 1999 John Wiley & Sons, Inc.

The research investigated the association between school engagement and adult education and occupation outcomes, within the context of a 1985 Australian longitudinal national cohort study of the factors affecting children's long‐term health and well‐being. School engagement may be more modifiable than other factors related to academic success, such as academic attainment, which is influenced by family background. A School Engagement Index was constructed using questionnaire items on school enjoyment and boredom. Related school engagement items included learner self‐concept, motivation to learn, sense of belonging, participation in school or extra‐mural activities, and enjoyment of physical activity. In 2004–2006, participants (aged 26 to 30 years) reported their highest level of education achieved and current occupation. Potential covariates included age, sex, markers of socio‐economic status in childhood, personality and school‐level variables (i.e., number of students, single sex versus co‐education; government, private or independent). Logistic regression was used to estimate the odds of achieving post‐compulsory school education and achieving higher status occupations. Findings revealed that each unit of school engagement was independently associated with a 10% higher odds (OR 1.10 95% CI 1.01,1.21) of achieving a post‐compulsory school education. Maternal education, self‐concept as a learner, motivation to learn, all also significantly predicted achieving post‐compulsory school education. School engagement was found to mediate the association between the personality characteristic of agreeableness and education outcomes. Higher school engagement was also independently associated with achieving higher status occupations 20 years later (OR 1.11 95% CI 1.03, 1.20). Importantly, this was independent of a host of background factors.  相似文献

Suicidal and help‐seeking behaviors of students of color remain a significant problem on college campuses. Self‐reported suicidal experiences and help‐seeking behavior of diverse students are examined on the basis of results from a national survey of college student mental health. The results suggest significant differences in the expression of suicidal thoughts and behavior across racial and ethnic groups and different experiences in their referral for, and utilization of, professional help.  相似文献

Disoriented, punitive, and caregiving/role‐confused attachment behaviors are associated with psychopathology in childhood, but have not been assessed in adolescence. A total of 120 low‐income late adolescents (aged 18–23 years) and parents were assessed in a conflict‐resolution paradigm. Their interactions were coded with the Goal‐Corrected Partnership in Adolescence Coding Scales. Confirmatory factor analysis demonstrated that the three disorganized constructs (punitive, caregiving, and disoriented interaction) were best represented as distinct factors and were separable from a fourth factor for collaboration. The four factors were then assessed in relation to measures of attachment disorganization, partner abuse, and psychopathology. Results indicate that forms of disorganized behavior first described in early childhood can also be reliably assessed in adolescence and are associated with maladaptive outcomes across multiple domains.  相似文献

This four‐wave prospective longitudinal study evaluated stability of language in 324 children from early childhood to adolescence. Structural equation modeling supported loadings of multiple age‐appropriate multisource measures of child language on single‐factor core language skills at 20 months and 4, 10, and 14 years. Large stability coefficients (standardized indirect effect = .46) were obtained between language latent variables from early childhood to adolescence even when accounting for child nonverbal intelligence and social competence and maternal verbal intelligence, education, speech, and social desirability. Stability coefficients were similar for girls and boys. Stability of core language skill was stronger from 4 to 10 to 14 years than from 20 months to 4 years, so early intervention to improve lagging language is recommended.  相似文献

Lean six sigma is a management methodology that firms can employ to achieve substantial improvement in supply chain performance. However, few pedagogical exercises facilitate students’ use of a comprehensive set of lean six sigma principles within a supply chain context. We describe the Airplane Supply Chain Simulation that helps students understand how lean six sigma concepts may be leveraged to improve supply chain performance. The basis of this simulation is a four‐tier supply chain, consisting of suppliers (two tiers), a manufacturer, and a customer, that produces three models of paper airplanes to meet randomly distributed customer demand. In the first of three successive runs, a highly structured simulation is executed in which supply chain roles are well defined, material flows are convoluted, and a “push” production strategy is followed. The first simulation as the “current state” and, for the second and third simulation runs, challenge competing student teams to leverage lean six sigma concepts to develop a “future state” that enables the fulfillment of all customer orders at the lowest cost. Results based on statistical analyses of survey response data from 194 MBA students show that the Airplane Supply Chain Simulation is an effective participative, team‐based learning tool.  相似文献

The aim of the present study was to examine the spelling development of Greek‐speaking children in the early school grades. Although Greek orthography is regular for reading, it is much less transparent as far as spelling is concerned. Spelling development was investigated using a word spelling task designed to explore the effects of word length, familiarity and spelling regularity. One hundred and fifty normally developing primary school children living in Cyprus took part in the study. Results suggest that the children employed both phonological and lexical strategies in spelling Greek words. Results indicated that sub‐lexical procedures were more marked for younger children, whereas lexical processing was employed more widely by older children. The findings are interpreted in terms of stage developmental models.  相似文献

From the perspective of the Fuzzy Trace Theory, this study investigated the impacts of concept maps with two strategic orientations (comprehensive and thematic representations) on readers' performance of cognitive operations (such as perception, verbatim memory, gist reasoning and syntheses) while the readers were reading two history articles that argue from different perspectives about a historical incident that had a profound impact on Taiwan. The results show that the design and focus of the concept maps may influence the formation of mental representations, and that this may be facilitative or constraining in regard to the readers' memory formation and reasoning about the reading materials. Based on these findings, the meaning of constraining effects of concept maps is discussed, and an instructional method involving the progressive elaboration of concept map systems is recommended.  相似文献
