“Double-dose” coursework has become an increasingly popular strategy to assist low-performing students succeed in academic coursework. Chicago implemented a “double-dose” English policy in 2003. This policy not only provided additional instructional time to struggling readers, but also intensified skill-based sorting in English classes. I use policy-induced variation to infer the policy effect on students’ reading achievement and the effect mediated by classroom peer ability change. Results show very weak, but positive effects of taking double-dose English for students with average skills. However, potential benefits of doubled instructional time are likely to be offset by negative effects of declines in classroom peer ability. Students with very weak skills experienced minimal change in classroom peer ability, and two-period coursework is likely to benefit these students.  相似文献

The integration of dance into K–12 curriculum can help students to learn better, encouraging deeper exploration and active engagement with content knowledge. The purpose of this intervention study was to determine how the integration of dance and social studies with an anthropological framework affects student learning of content knowledge in social studies, as well as student attitude toward the topic. An anthropological framework was implemented to foster respectful investigation of culture. As a supplement to a sixth-grade unit on Ancient Egypt, the experimental group received four intervention lessons, incorporating creative dance. Results show that at posttest the intervention group had significantly higher content knowledge than the control group, and qualitative student responses from the intervention group suggest extremely positive feelings toward experiences in the program. This suggests that incorporating dance into sixth-grade social studies with an anthropological framework can encourage student exploration and increase understanding of content.  相似文献

This article examines a modern, former polytechnic granted the status of university in 1992, to illustrate the state gender pay gap in the UK and suggests that to talk of the state pay gap is too simplistic as it does not take into account variations in the size of the pay gap in different job grades. The article also examines satisfaction levels with pay for two groups of staff, administrative and academic and shows how satisfaction with pay, promotion and conditions also varies between the grades. Previous research that concluded that women are more satisfied with their pay than men is, again, too simplistic as it does not consider the affect of staff grade. The article argues that there is a link between the size of the pay gap, staff grade, occupational gender segregation and expressing dissatisfaction.  相似文献

Using nationally representative data from the Early Childhood Longitudinal Study-Kindergarten Cohort (N = 21,409; 10,452 girls and 10,957 boys; mean age = 7.24 years), the association between first-grade classroom sex composition (CSC), measured as the percentage of female students, and end of the year academic (reading, mathematics) and socio-emotional (externalizing problems, internalizing problems, self-control, interpersonal skills) outcomes was examined. Using multilevel modeling techniques and controlling for prior achievement levels, CSC was positively associated with children’s reading achievement at the end of first grade; students performed better in reading in classes with a higher percentage of female students. CSC was also associated with three of the socio-emotional outcomes; controlling for prior levels, students in classrooms with a higher percentage of girls had better self-control and interpersonal skills and fewer internalizing problems. Classroom behavior mediated the effects of CSC on reading achievement and the socio-emotional outcomes. Implications for the composition of first-grade classrooms are discussed.  相似文献

随着我国高校扩招的浪潮进一步推进,大学教育也已从精英教育阶段步入了大众化教育阶段,许多专家和学者也随之把注意力转移到高等教育大众化的研究和探索方面,从而疏忽了对新形势下精英教育的价值和发展前景的关注。针对三表院校学生听、说能力和教师教学现状,本文探讨大学英语听、说教学精英战略。黑龙江科技学院50名非英语专业二年级学生被选取作为受试,经过从恐讲到模仿再到自由交流的过程性培养,大部分学生的英语听、说能力得到提高。这种大学英语听、说教学精英战略对三表学生英语听、说能力的提高有一定帮助。  相似文献

路面使用性能的评价和预测是路面管理系统的重要环节,对合理地确定养护措施,制定养护方案,安排养护费用起着重要作用。本文在讨论常用综合评价模型的基础之上,提出了三种以改进指标为基准的、以高速公路养护为目的的回归模型,从不同的思维方式去模拟专家的评分过程,最后通过组合原理,建立起以灰色关联度确定权重的综合评价模型。并应用实例验证了本章所给出的沥青路面使用性能综合评价模型作为我国高等级沥青路面养护维修标准的可行性。  相似文献

基于灰色关联度的区域自主创新能力模糊评价   总被引:5,自引:1,他引:4  
自主创新是企业提高核心竞争力的重要途径,也是一个国家长远发展的核心驱动力。从创新基础,创新投入与创新产出三个方面选取11 个评价指标,运用灰色关联模糊评价方法对我国东、中、西各区域典型省份进行实证研究;这种研究方法避免了传统的在综合评价区域自主创新能力过程中遇到的权重赋值的人为性问题,使得实证结果更加科学、客观。研究表明,我国区域自主创新能力梯度差异显著,在此基础上针对各区域不同特点进行分析并提出改进性意见。  相似文献
