Dropping out of school has been associated with a student’s ethnicity, socioeconomic status, challenging behaviours and low academic achievement. This paper describes research conducted with 1050 students aged 12–15, in three North Queensland urban high schools to investigate issues related to Indigenous and non-Indigenous students at risk of dropping out of school before gaining adequate qualifications.  相似文献

Homosexuality is widely perceived among many Muslims as a ‘western disease’, a natural outcome of the West's secularity and cultural degeneracy. In spite of the emergence of more liberal attitudes towards sexual differences in modern times, moral issues have not lost their relevance in polemical discourse against homosexuality among many Muslims. The heightened visibility of homosexuals, together with the decriminalisation of homosexuality, lie at the heart of Muslim objection; such movements towards the acceptance of homosexuality are viewed as a concerted and unified homosexual front attempting to squeeze out the hegemonic heterosexual norm. The common response among many Muslims to remedy this perceived ideological corruption is to resort to Islamic doctrine, which prohibits homosexuality and gives merit to heterosexism. This paper reports on some findings from a study by the author which examines how a group of Australian Muslim teachers deliberate on how to include studies on homosexuality as part of a wider dialogue on developing comprehensive sexuality education for Muslim youth. In their deliberations, teachers craft pedagogies which appropriate moral frameworks and expressions of embracing sexual difference. These pedagogical propositions give insight into how teachers generate epistemological, ethical and ontological approaches to critical thought about the subject.  相似文献

OBJECTIVE: To examine whether children with substantiated maltreatment reports between 4 and 8 years of age differ from children with unsubstantiated reports on any of 10 behavioral and developmental outcomes. METHOD: Longitudinal data from 806 children and their adult caregivers collected in four US study sites were pooled and analyzed using Analysis of Variance (ANOVA) and multivariate linear regression. RESULTS: There were no significant differences between the mean scores of children with unsubstantiated and substantiated maltreatment reports filed between 4 and 8 years of age for any of the 10 behavioral and developmental outcomes. In the multivariate analysis, substantiation status was not significantly associated with any of the 10 outcomes after adjusting for prior functioning, prior maltreatment status, and sociodemographic characteristics. Findings from within-site analyses were generally consistent with the pooled analyses in finding no association between substantiation status and the outcomes examined. CONCLUSIONS: In this high-risk sample, the behavioral and developmental outcomes of 8-year-old children with unsubstantiated and substantiated maltreatment reports filed between ages 4 and 8 were indistinguishable. Future research should attempt to replicate these findings on probability samples that represent the full range of childhood maltreatment risk and with models that control for the impact of social services.  相似文献

Abstract

While professional development has been emphasised in many countries, few comparative studies have examined the degree of teachers’ participation in professional development and its effect on teachers. Using the TIMSS 2007 data, this study analyses to what extent teachers participated in professional development in 50 TIMSS countries and examines the relationship among high-quality teachers’ professional development, teachers’ beliefs, attitudes and job satisfaction. The study found that the extent to which teachers have participated in professional developmental activities was surprisingly low. In particular, teachers in 47 countries have rarely participated in active learning. The study also found that high-quality teacher professional development was significantly associated with greater job satisfaction, higher expectations for student performance and more positive attitudes in teachers concerning their implementing the school’s curriculum. Policy implications for professional development are discussed.  相似文献

Many factors influence the way individual students study, including but not limited to: previous coursework, attitudes toward the class (motivation, intimidation, risk, etc.), metacognition, and work schedules. However, little of this research has involved medical students. The present article asks the question, “Do individual medical students study differently for different classes?” Study skills surveys were given to United States medical students at an allopathic medical school and an osteopathic medical school. Students were surveyed near the end of their first year gross anatomy course and again near the end of their first year physiology course. Survey items included Likert scale and open‐ended questions about study habits and basic demographic information. The survey responses were correlated with each student's final grade percentages in the courses. Analysis revealed that the four most common study habits were reviewing lecture notes, taking practice examinations, completing learning exercises, and making drawings and diagrams. The two surveys (anatomy and physiology) from each individual were also compared to see if students reported different study habits in anatomy versus physiology. A negative correlation was found between changing study habits between courses and final anatomy grade percentages. Additional analyses suggest that those students who do change their study habits between courses are increasing the number of study strategies that they attempt. This increase in the number of study strategies attempted may not allow the student to reach the same depth of understanding as their colleagues who utilize fewer strategies.

In general, vocational psychologists have not been engaged in applied research that demonstrates how career interventions can improve educational problems that matter to relevant decision-makers and stakeholders. This article describes how vocational psychology can make a difference in K–12 education by embracing an interdisciplinary community-based approach. To illustrate this approach, a quasi-experimental evaluation of multiple after-school programs provided to a sample of Hispanic Americans is presented. This study offers a realistic example of how researchers in the field can induce change through the development of meaningful partnerships within the community.  相似文献

INTRODUCTION Let w be the set of all sequences of real or com- plex numbers and R∞, c and c0 be the sequence spaces of bounded, convergent and null sequences x=(xk), respectively. A sequence x∈R∞ is said to be almost convergent (Lorentz, 1948) if all Banach limits of x coincide. Lorentz (1948) proved that 1 c? = ??? x =( xk ) :linm 1n ∑kn= xk s exists, uniformly in s???. Maddox (1967; 1978) has defined x to be strongly almost convergent to a number L if 1 linm 1n ∑k n= xk s? L=0,…  相似文献
