This study reports relations between infant Ainsworth Strange Situation classifications, negative life events, and Adolescent Attachment Interview classifications. Overall, the stability of secure versus insecure classifications was 77%, and infant attachment classification was a significant predictor of adolescent attachment classification. Chi-square analyses indicate that negative life events are significantly related to change in attachment classification. The sample (n = 30) is drawn from the Family Lifestyles Project (FLS), an ongoing longitudinal study of children's development within the context of nonconventional family lifestyles. The distribution of family lifestyles within this study, unlike those in the full FLS sample, represent a higher proportion of conventional two-parent families (40%). There were no differences between adolescents reared in conventional or nonconventional families in the distribution of adolescent attachment security, the experience of negative life events, or the continuity of attachment from infancy through adolescence. 相似文献

The Sensitivity of Value-Added Teacher Effect Estimates to Different Mathematics Achievement Measures 总被引:1,自引:0,他引:1

Using longitudinal data from a cohort of middle school students from a large school district, we estimate separate "value-added" teacher effects for two subscales of a mathematics assessment under a variety of statistical models varying in form and degree of control for student background characteristics. We find that the variation in estimated effects resulting from the different mathematics achievement measures is large relative to variation resulting from choices about model specification, and that the variation within teachers across achievement measures is larger than the variation across teachers. These results suggest that conclusions about individual teachers' performance based on value-added models can be sensitive to the ways in which student achievement is measured. 相似文献

AbstractAcademic self-efficacy is critical to academic success. Hence those working in higher education need to make deliberate and substantial attempts to foster academic competence, confidence, persistence and resilience in the students they teach, given they are essential components of academic self-efficacy. Addressing an identified gap in the exemplars literature, this article pays particular attention to how exemplars can be used in an embedded and sustained manner with the intent of fostering and supporting these components. Taking into account the three dimensions of self-efficacy – strength, magnitude and generality – and the various sources of information students draw upon to make judgements about their capabilities, four inter-dependent and inter-related practices and associated experiences are identified. We argue that collectively these practices and experiences can accentuate the positive effects and ameliorate the potential negative effects of exemplar use on student academic self-efficacy. 相似文献

Two experiments were performed to evaluate the effects of definition adjunct questions on concept learning. Each experiment included 132 undergraduates at a large midwestern university. In both experiments, subjects studied a passage containing matched or unmatched application questions only, matched or unmatched application questions preceded by a definition question, definition questions only, or no questions at all. The critical attributes of the to-be-learned concepts were more salient in the sets of examples and nonexamples presented in the matched application questions than in the unmatched application questions. Subjects took a criterion test which consisted of novel matched and unmatched application questions. In both experiments, only unmatched application adjunct questions preceded by a definition question produced significantly higher performance on the criterion questions than definition questions only. The discussion focused on the importance of definition questions for effective use of different types of application questions. 相似文献
