Student engagement is an important contributor to school success, yet high school students routinely describe themselves as disengaged. Identifying factors that alter (increase) engagement is a key aspect of improving support for student achievement. This study investigated students’ perceptions of autonomy, teacher connection, and academic competence as predictors of changes in student engagement within the classroom from the start to the end of a course. Participants were 578 (58% female) diverse (67.8% White, 25.2% African American, 5.1% Hispanic, 1.2% Asian American) high school students from 34 classrooms who provided questionnaire data both at the start and the end of a single course. Novel results from a cross-lagged model demonstrated that students who perceived their classrooms as allowing and encouraging their own autonomy in the first few weeks increased their engagement throughout the course, rather than the typical decline in engagement that was demonstrated by students in other classrooms. This finding is unique in that it extended to both students’ perceptions of engagement and observations of student engagement, suggesting a fairly robust pattern. The pertinence of this finding to adolescent developmental needs and its relationship to educational practice is discussed.  相似文献

Empirical evidence suggests that religiousness is related negatively to adolescent substance use; yet, we know little about how such protective effects might occur. The current study examined whether parents’ and adolescents’ religiousness are associated positively with parental, religious, and self-monitoring, which in turn are related to higher self-control, thereby related to lower adolescent substance use. Participants were 220 adolescents (45 % female) who were interviewed at ages 10–16 and again 2.4 years later. Structural equation modeling analyses suggested that higher adolescents’ religiousness at Time 1 was related to lower substance use at Time 2 indirectly through religious monitoring, self-monitoring, and self-control. Higher parents’ religiousness at Time 1 was associated with higher parental monitoring at Time 2, which in turn was related to lower adolescent substance use at Time 2 directly and indirectly through higher adolescent self-control. The results illustrate that adolescents with high awareness of being monitored by God are likely to show high self-control abilities and, consequently, low substance use. The findings further suggest that adolescents’ religiousness as well as their religious environments (e.g., familial context) can facilitate desirable developmental outcomes.  相似文献

A new inventory for examining the first six of Erikson's psychosocial stages is described. The self-report questionnaire, developed in a pilot study of 97 adolescents and tested in a study of 622 adolescents, has 12 items for each subscale. Measures of reliability and validity are reported. It is concluded that the Erikson Psychosocial Stage Inventory (EPSI) is a useful measure for researchers interested in development from early adolescence and in mapping changes as a function of life events.This research was supported by a grant from the Education Research and Development Committee.Received Ph.D. from University of Melbourne. Current research interests are adolescent adjustment, ethnicity, and sex-role psychology.Received Ph.D. from University of Melbourne. Current research interests are effects of unemployment and adolescent adjustment.Received Ph.D. from Florida State University. Current research interests are sex-role psychology and adolescence.  相似文献

The marginality hypothesis is an attempt to relate the voting margins of members of Congress to their subsequent legislative behavior. A major corollary of the hypothesis is that members of Congress with small victory margins will be more responsive to constituents than those with large victory margins. This has been assumed to mean that electorally secure representatives can afford to be more loyal to their congressional parties, since they have less cause to worry about their chances for reelection. Previous empirical studies have produced mixed results. We ask the question in a different way: Do changes in marginality affect party voting within Congress? If so, major shifts in the electorate potentially can have a fundamental impact on the behavior of Congress itself. We find that this is not true. Electoral margin is simply not related to party loyalty.  相似文献

Voluntary policy compliance is an important yet rarely studied topic in public administration. To address the paucity of research, this article proposes and empirically tests a conceptual framework that ties policy transparency and policy understanding to voluntary policy compliance intentions. The reasoning is that the extent to which citizens understand a policy contributes to their intentions to comply with that policy. Further, the authors argue that policy transparency indirectly influences voluntary policy compliance intentions through a positive effect on citizens’ levels of policy understanding. To enhance the validity of the findings, the authors assess these relationships across two policy domains. The findings reflect an indirect positive effect of transparency on voluntary compliance occurring through policy understanding. However, this emerged only for one policy domain. These results suggest that the effects of policy transparency on policy understanding and voluntary policy compliance intentions may depend on the policy domain.  相似文献

If manufacturing a safer cigarette is technically possible--an open question--then mandating that tobacco manufacturers improve the safety of cigarettes would likely have both positive and negative implications for the nation's health. On the one hand, removing toxins may reduce the incidence of smoking-related diseases and premature mortality in smokers. On the other hand, smokers might be less inclined to quit, those who have quit might resume the habit, and youth who have never smoked will have one less reason to avoid tobacco use. To assess the expected population health impacts of a legislative or regulatory mandate, we created the Tobacco Policy Model, a system dynamics computer simulation model. The model relies on secondary data and simulates the U.S. population over time spans as long as 50 years. Our simulation results reveal that even if requiring cigarettes to be safer makes smoking more attractive and increases tobacco use, a net gain in population health is still possible.  相似文献

State sector reform was an integral component of the radical economic and social policy changes enacted by New Zealand governments between 1984 and 1991. This reform replaced the traditional tenured public service with a contractual regime. Through a comparison with Denmark, it is shown that New Zealand's reforms were not unique. Similar reforms were enacted in Denmark. But contrary to what occurred in New Zealand, the Danish reforms had already begun in the 1960s, and have since been gradually expanded. The parallel contractual regimes introduced in the two countries are accounted for by an increasing demand among politicians to secure a civil service that is responsive to political executive demands. However, because of institutional differences and diverging regulatory regimes, the strategic approaches in the two countries have been different. Whereas the New Zealand approach was dominated by an appeal to a coherent and sophisticated body of theoretical knowledge, combined with strict formalization, the Danish strategy has been based on political bargaining with the civil service unions. In both cases the reforms rest on critical assumptions regarding their positive and negative implications.  相似文献
