The issue of race differences in standardized test scores and academic achievement continues to be a vexing one for behavioral scientists and society at large. Ellis and Ryan (2003) suggested that a portion of the cognitive-ability test performance differences between White/Caucasian-American and Black/African-American college students could be attributed to the greater use of ineffective test-taking strategies by the latter group. We replicated and extended their findings by using three outcomes—exam scores in a single academic course, self-reported GPA, and a measure of verbal abilities. Ellis and Ryan reported that the variance in cognitive-ability test performance explained by race dropped by 48% (i.e., from 21% originally to 11%) when controlling for the mediator, ineffective test-taking strategies. Our results were less dramatic, but also indicated that ineffective test-taking strategies accounted for 19% to 25% of the variance originally explained by race. In addition, reminiscent of the disidentification effect, supplementary analyses showed that academic/intellectual self-perceptions correlated with the criterion measures but only for White participants. These results suggest that a portion of the race difference on test scores might be accounted for by test-taking strategies.  相似文献

This study examined the factor structure of the Emotional Autonomy Scale (EAS) as proposed by Steinberg and Silverberg. Participants were from three independent samples of adolescents in grades 6 (n = 1,842), 8 (n = 1,769), and 10 (n = 1,232), with each sample consisting of three ethnic groups: African American, European American, and Mexican American. None of the confirmatory factor analyses for these samples supported the factor structure proposed by Steinberg and Silverberg. From the three models tested, the EAS is best described by the four originally proposed factors, combined with two method factors, one consisting of the positively worded scale items and one consisting of the negatively worded scale items. Results show that the EAS exhibits poor construct validity and behaves quite differently for the different grade and ethnic groups. The strong impact of method variance on the factor structure is discussed. Although various alternative solutions to the psychometric problems in the EAS are proposed, the most credible solution may be to reexamine the conceptual foundations of emotional autonomy and develop better measures of those concepts for adolescents.  相似文献

A combination of high production and hardware costs, limited programme demands and cheap and easy videotape alternatives are likely to restrict severely the progress of interactive videodisc in schools and possibly elsewhere. These reservations are discussed.  相似文献

The resistance of many ministers to the teaching role may be rooted in the dynamics of power and control, as seen in their preference for one‐to‐one and one‐to‐many dimensions of ministry rather than the one‐to‐group context of teaching. Another source of resistance is the minister's narrow understanding of teaching and the minister's limited repertoire of teaching skills. This paper proposes seven metaphors for teaching that can be clustered under one dominant motif—interpreter. These metaphors may empower a minister's move toward a self‐image as teacher  相似文献

Objective

While the relationship between abusive parenting and violent delinquency has been well established, the cognitive and emotional processes by which this occurs remain relatively unidentified. The objective of this work is to apply a conceptual model linking abusive parenting to the conversion of shame into blaming others and therefore to violent delinquency.

Methods

A retrospective study of 112 adolescents (90 male; 22 female; ages 12-19 years; M = 15.6; SD = 1.4) who were incarcerated in a juvenile detention facility pending criminal charges, completed measures of exposure to abusive and nonabusive discipline, expressed and converted shame, and violent delinquency.

Results

Findings tend to confirm the conceptual model. Subjects who converted shame (i.e., low expressed shame, high blaming others) tended to have more exposure to abusive parenting and showed more violent delinquent behavior than their peers who showed expressed shame. Subjects who showed expressed shame (i.e., high expressed shame, low blaming others) showed less violent delinquency than those who showed converted shame.

Conclusions

Abusive parenting impacts delinquency directly and indirectly through the effects of shame that is converted. Abusive parenting leads to the conversion of shame to blaming others, which in turn leads to violent delinquent behavior.

Practice implications

For juvenile offenders, the conversion of shame into blaming others appears to contribute to pathological outcomes in relation to trauma. Translation of this work into clinical practice is recommended.  相似文献

Summary The thrust of this article is that although different theories may share some of the same terminology they may differ considerably in the interpretation which they impose on it and, therefore, on the educational practices which they underwrite. Specifically a brief examination has been made here of the concept of cognitive conflict as it occurs in the theories of Bruner, Case and Piaget-Inhelder, and of the similarities and differences in classroom practices which arise from theoretical commitment.  相似文献
