Interpersonal violence among youth is a growing problem in many communities and schools across the nation. The causes of violence are multiple and complex. This paper examines the extent and nature of interpersonal violence among youth as well as the individual and societal factors which contribute to youth violence. Adolescents are disproportionately represented as both victims and perpetrators of fatal and nonfatal assaultive violence. Homicide rates among young men in the United States are vastly greater than those of other Western industrialized nations. Persons age 12–24 years face the highest risk of nonfatal violent victimization of any segment of our society. Arrest rates for homicide, rape, robbery, and aggravated assault peak among adolescents and young adults. Further, arrest rates for murder and other violent crimes have increased substantially among this age group since the mid-1980s. Effective prevention programs will require combinations of interventions aimed at multiple factors and delivered through many channels. 相似文献

For the past two decades, those involved in teacher training have encouraged teachers to incorporate evidence from research into a process of critical reflection to improve the quality of their decisions. Using research as part of a deliberative reflective process has been thought to enable teachers to learn from their practice. However, teachers’ decision-making has proven highly impervious to external influence. Teachers often resist reflective models that attempt to take their thinking to deeper, critical levels and are unlikely to use empirical evidence to inform their decisions. Given these conditions, this study seeks further insight into teachers’ pedagogical decision-making amidst the complex dynamics of ‘real-world’ educational contexts. Based on a systematic review of over three decades of decision research, a questionnaire was developed to investigate the decision process of 80 pre- and in-service teachers working in the post-compulsory sector. Data were analysed to uncover how these teachers made sense of the range of information that came into play when deciding how to resolve a pedagogical issue and the sources they used to inform their decision-making. If those involved in pre- and in-service teacher training could build upon teachers’ intrinsic decision processes, they could potentially support greater decision effectiveness. 相似文献

Scanlon (1967,1970) found significant color effects when he content analyzed and compared written accounts about achromatic and chromatic versions of the same television programs. The present study which replicated many aspects of Scanlon’s studies but used more rigorous and systematic procedures, confirms Scanlon’s idea as a useful one but does not support Scanlon’s findings. It appears that for some simple cognitive tasks, a chromatic presentation seems to elicit more verbal responses than an achromatic version. 相似文献

This study employed a case-study approach to reveal how an ability to think with mental models contributes to differences
in students’ understanding of molecular geometry and polarity. We were interested in characterizing features and levels of
sophistication regarding first-year university chemistry learners’ mental modeling behaviors while the learners were solving
problems associated with spatial information. To serve this purpose, we conducted case studies on nine students who were sampled
from high-scoring, moderate-scoring, and low-scoring students. Our findings point to five characteristics of mental modeling
ability that distinguish students in the high-, moderate-, and low-ability groups from one another. Although the levels of
mental modeling abilities have been described in categories (high, moderate, and low), they can be thought of as a continuum
with the low-ability group reflecting students who have very limited ability to generate and use mental models whereas students
in the high-ability group not only construct and use mental models as a thinking tool, but also analyze the problems to be
solved, evaluate their mental models, and oversee entire mental modeling processes. Cross-case comparisons for students with
different levels of mental modeling ability indicate that experiences of generating and manipulating a mental model based
on imposed propositions are crucial for a learner’s efforts to incorporate content knowledge with visual-spatial thinking
skills. This paper summarizes potential factors that undermine learners’ comprehension of molecular geometry and polarity
and that influence mastery of this mental modeling ability. 相似文献

The purpose of this study was to empirically investigate, in a large-scale assessment, the prevalence of enquiry-based teaching, as defined by PISA, implemented in science lessons, and the extent to which it is related to students from different socioeconomic status (SES) family backgrounds in the U.S. The Programme of International Student Assessment (PISA) 2015 data including 5,146 students in the U.S. were used. A Latent Profile Analysis (LPA) was conducted to classify students into different science teaching subgroups. Mixture regression analysis was conducted to examine whether there the association between SES and achievement varied across science teaching subgroups. Four science teaching subgroups were identified, varying in the frequency of and type of teaching practices used. Students’ attitudes, gender, science instruction time, and reading achievement are significant predictors of the subgroup membership. SES-achievement gap also varied across the science teaching subgroups. Discussions for the results and suggestions for future study were presented. 相似文献

This study was designed to assess the impacts of maltreatment reporting policies and reporting system structures on four aspects of entry into the child protection system (the maltreatment referral rate, the percentage of referrals screened in for investigation, the screened-in report rate and the substantiated report rate). Using secondary data from several sources, eight multiple linear regression models were created and analyzed. Results from a sample of 44 states indicated significant effects for system structure but no effects for reporting policies. Specifically, states with decentralized reporting system structures were significantly more restrictive in access than other states. These results have implications for child welfare administrators and policymakers seeking to maximize access for maltreated children and their families. 相似文献
