“学习能量”有关学习的倾向、态度和价值观,是英国教育界近年来出现的讨论“学会学习”的一种新的话语.它包含了改变与学习、意义建构、探究意识、创造力、学习关系、战略意识和心理弹性七大维度.“有效终身学习指标”作为其动态测评工具,对教学和科研的意义重大.“学习能量”为切实改进教学法、进行课程变革、开展个性化学习以及发展终身学习型社会提供了有力的理论依据和实践框架.它最大的创新之处在于激发并解放了学习者终身学习的能动性,对进一步深化中国的教育改革有着重要的启示.  相似文献

This article explores the intersection of new, large-scale standards-based testing, teacher accountability policy, and secondary curriculum and instruction in the United States. Two federally funded consortia – the Smarter Balanced Assessment Consortium and the Partnership for Readiness of College and Careers – prove focal to this paper, as these two organisations are creating new tests that will assess 42–49% of the K–12 student population in the United States in 2014–2015. Because greater teacher accountability for student performance will be given for these tests, there is more reason to pay attention to what these tests measure and what they do not. Our analysis suggests that these new tests will hold secondary English teachers accountable for literacy and disciplinary knowledge outside the field of English and thus raise important questions about what English teachers should, can and will do, especially when their jobs are on the line.  相似文献

I use Danish administrative data to investigate the consequences of summer camp participation combined with a one-year follow-up program for disadvantaged boys on academic, personal, and social competencies. My identification strategy relies on individual-level panel data that enable me to observe outcomes before and after summer camp participation. Using a difference-in-differences strategy, I find overall positive effects on academic and personal competencies that reduce the gap to a matched group of boys with similar background characteristics by 40 to 80 percent. Further, I exploit a structural change in the follow-up program to evaluate how different mentoring strategies affect outcomes. In 2017, the follow-up program was changed from individual mentoring to group mentoring. Using a triple differences strategy, I find that group mentoring in the follow-up program improves personal and social competencies, suggesting that the format of the follow-up program is crucial for effects on personal and social competencies.  相似文献

Teachers’ diagnostic competence for accurately judging students’ achievement is essential for instructional practice and professional decisions. To promote their judgment accuracy, it is important to know if this is a general or domain-specific skill. We investigated teachers’ judgment accuracy in German language (one subdomain: reading) and mathematics (two subdomains: geometry; stochastics) and examined differences across domains (i.e., German and mathematics) and across subdomains (reading; geometry; stochastics). We examined the judgment accuracy of 59 German elementary school teachers who teach both German and mathematics, judging the achievement of 1227 students in the three subdomains. We conducted multilevel analyses with a subsample of 39 teachers and 787 students and calculated different accuracy components (i.e., rank, level, and differentiation) to examine the comparability of our results. In line with prior research, findings revealed that teachers’ judgments were fairly accurate. However, there were significant differences between teachers’ average judgment accuracy in different subdomains (between-person comparisons) and no or only a weak relation between individual teachers’ judgment accuracy in different subdomains (within-person comparisons). Findings support the notion that teachers’ judgment accuracy of student achievement is domain-specific with respect to the investigated subdomains. Practical implications for the promotion of teacher judgment accuracy are discussed.  相似文献

介绍了数字图书馆中基于XML/RDF的两种元数据描述技术,一种是传统的机读格式MARC元数据,一种是DC元数据。通过对比发现,DC元数据描述的数字资源信息更为直观、灵活、易读,但DC元数据并不能完全取代MARC元数据,二者各有优点和不足,并相互补充。  相似文献

基础阶段的核心力量训练更倾向于关注静力姿势的练习,特别是对核心肌群的本体感觉进行刺激,而且要加大核心肌群的肌肉力量,首先发展神经--肌肉系统的能力,为下一阶段的训练做好准备。至于训练时间,可以根据不同的运动员制定不同的训练时间,但是必须至少1-2周,在基础阶段需要持续,但在后期,很多练习也应持续。静立姿势的练习比较关注动作的规范准确,不适宜有过大的负荷量,可以随着静力姿势维持的时间长度来调整运动的负荷强度。  相似文献

The Common Core State Standards and Response to Intervention are significant contemporary educational initiatives that have emerged largely in isolation from one another. We argue that an integration of these initiatives is beneficial. We trace the independent development of these two initiatives and offer suggestions for how they might fruitfully transact, fully supporting vulnerable readers in their efforts to master sophisticated standards. Results from a school implementing these initiatives as an integrated whole are discussed.  相似文献
