The impact of part-time employment on adolescent functioning remains unclear because most studies fail to adequately control for differential selection into the workplace. The present study reanalyzes data from L. Steinberg, S. Fegley, and S. M. Dornbusch (1993) using multiple imputation, which minimizes bias in effect size estimation, and 2 types of propensity score matching, to account for selection effects. In this sample (N = 1,792; Grades 10-11, M = 16.26), youth who begin working more than 20 hr per week evince declines in school engagement and increases in substance use and delinquency compared with youth who remain unemployed. Conversely, working 20 hr or less a week has negligible effects, positive or negative, on academic, psychological, or behavioral outcomes. 相似文献

Family rearing antecedents of pubertal timing 总被引:5,自引:2,他引:3

Two general evolutionary hypotheses were tested on 756 White children (397 girls) studied longitudinally: (1) rearing experiences would predict pubertal timing; and (2) children would prove differentially susceptible to rearing. Analysis of pubertal measurements, including some based on repeated physical assessments, showed that mothering and fathering, earlier and later in childhood, predicted pubertal development, but only for girls, with negative parenting appearing most influential; maternal harsh control predicted earlier menarche. Rearing effects varied by infant negative emotionality, proving stronger (and opposite) for girls who in infancy were lower rather than higher in negativity. Maternal menarche, controlled in all analyses, was a stronger predictor than rearing. Findings are discussed in terms of theory development, genetic and nutritional influences, and sample restrictions. 相似文献

Callous-unemotional (CU) traits are a risk factor for severe and persistent patterns of juvenile delinquency. Given the influence of CU trait assessments in justice-system settings, it is important to determine whether the predictive utility of CU traits is conditional on the absence of protective psychosocial factors. Employing a sample of justice-involved male youth (N = 1,216, Mage = 15.29), this study examined whether psychosocial maturity (PSM) outweighs or attenuates the effect of CU traits on delinquency. Results indicated that youth with high CU traits or low PSM offended more during the year following their first arrest. Additionally, PSM moderated the relation between CU traits and offending, such that higher PSM was associated with less offending but only among low CU youth. 相似文献

The present study examined age differences in performance on the Tower of London, a measure of strategic planning, in a diverse sample of 890 individuals between the ages of 10 and 30. Although mature performance was attained by age 17 on relatively easy problems, performance on the hardest problems showed improvements into the early 20s. Furthermore, whereas age-related performance gains by children and adolescents (ages 10-17) on the hardest problems were partially mediated by maturational improvements in both working memory and impulse control, improved performance in adulthood (ages 18+) was fully mediated by late gains in impulse control. Findings support an emerging picture of late adolescence as a time of continuing improvement in planned, goal-directed behavior. 相似文献

Validation of assessments intended to improve instruction and learning should include evidence of instructional sensitivity. This study investigated the instructional sensitivity of a standards-based ninth-grade performance assessment that required students to write an essay about conflict in a literary work. Before administering the assessment, teachers of 886 ninth-grade students were randomly assigned to one of three instructional groups: literary analysis, organization of writing, and teacher-selected instruction. Despite the short duration of instruction (8 class periods), results support the instructional sensitivity of the assessment in two ways: Instruction on literary analysis significantly improved students' ability to analyze and describe conflicts in literature, and instruction on the organization of writing led to significantly higher scores on measures of coherence and organization. 相似文献

In this article we examine the ability of contextual information to enhance assessment of behavior problems in schools. Capitalizing on the multisituational structure of the Adjustment Scales for Children and Adolescents, exploratory and confirmatory analyses with a representative national sample (N = 1,400, ages 5–17 years) revealed three unique and reliable behavioral situtypes (problems in Peer Contexts, Academic Contexts, and Teacher Contexts). The situtypes were found internally consistent and structurally generalizable across age, sex, and ethnicity. Multiple logistic and discriminant analyses confirmed the ability of the situtypes to identify accurately those youth independently diagnosed as emotionally disturbed, as well as distinguish those diagnosed as learning disabled. Information gleaned from the situtypes was substantially better able than conventional psychopathology syndromes (attention‐deficit hyperactivity, oppositional defiance, etc.) to forecast later academic achievement. Implications for informing motivation and intervention are discussed. © 2005 Wiley Periodicals, Inc. Psychol Schs 42: 121–136, 2005. 相似文献

Today, science is a major part of Western culture. One advantage of informal learning environments is that they are (potentially) open to a wide range of populations with varying levels of interest and knowledge. Because of their informal nature, documenting learning has proven challenging. Studies that assess learning in museums, therefore, must employ theories of learning that encompass a more complex view of what learning is. This qualitative study was conducted with a population of high-level pedagogical staff from museums in Israel, Europe and the USA. Its purpose was to characterise staff perception of the goals of science museums and how these goals are manifested in the exhibits. Interviews with 17 staff revealed a wide range of goals that come into play in the different science museums. Findings suggest that the pedagogical staff perceive the science museum’s goals as being to change public views regarding science, promote science education, and reduce disparities between populations. According to museum staff, science museums have an important role in changing visitors’ approach towards science, as well as providing an additional source of science education. 相似文献

This paper describes an item response model for multiple-choice items and illustrates its application in item analysis. The model provides parametric and graphical summaries of the performance of each alternative associated with a multiple-choice item; the summaries describe each alternative's relationship to the proficiency being measured. The interpretation of the parameters of the multiple-choice model and the use of the model in item analysis are illustrated using data obtained from a pilot test of mathematics achievement items. The use of such item analysis for the detection of flawed items, for item design and development, and for test construction is discussed. 相似文献
