This study examined whether practice with arithmetic problems presented in a nontraditional problem format improves understanding of mathematical equivalence. Children (M age = 8;0; N = 90) were randomly assigned to practice addition in one of three conditions: (a) traditional, in which problems were presented in the traditional "operations on left side" format (e.g., 9 + 8 = 17); (b) nontraditional, in which problems were presented in a nontraditional format (e.g., 17 = 9 + 8); or (c) no extra practice. Children developed a better understanding of mathematical equivalence after receiving nontraditional practice than after receiving traditional practice or no extra practice. Results suggest that minor differences in early input can yield substantial differences in children's understanding of fundamental concepts. 相似文献

The Science Teachers Learning from Lesson Analysis (STeLLA) project is a videobased analysis‐of‐practice PD program aimed at improving teacher and student learning at the upper elementary level. The PD program developed and utilized two “lenses,” a Science Content Storyline Lens and a Student Thinking Lens, to help teachers analyze science teaching and learning and to improve teaching practices in this year‐long program. Participants included 48 teachers (n = 32 experimental, n = 16 control) and 1,490 students. The STeLLA program significantly improved teachers' science content knowledge and their ability to analyze science teaching. Notably, the STeLLA teachers further increased their classroom use of science teaching strategies associated with both lenses while their students increased their science content knowledge. Multi‐level HLM analyses linked higher average gains in student learning with teachers' science content knowledge, teachers' pedagogical content knowledge about student thinking, and teaching practices aimed at improving the coherence of the science content storyline. This paper highlights the importance of the science content storyline in the STeLLA program and discusses its potential significance in science teaching and professional development more broadly. © 2011 Wiley Periodicals, Inc., J Res Sci Teach 48: 117–148, 2011 相似文献

Using national data, this study examined out-migration behavior of college graduates who attended in-state institutions in
the United States. Unlike previous studies on the issue of student migration, in which researchers used a single equation
approach, the present study employed a multi-level technique to assess the effects of factors from individual, institutional,
and state levels on post-graduation migration. The study findings suggest that grant recipients, students who applied to multiple
institutions, and college graduates from highly selective institutions are more likely to leave their native states, while
Hispanics, college graduates from doctoral institutions, and students who reside in states with higher gross domestic product
are more likely to remain in their native states. 相似文献

四个范式:欧洲档案学的观念和战略的变化——1840年以来西方档案观念与战略的变化 总被引:1,自引:1,他引:0
本报告首先梳理了西方档案理论与档案史,探讨了那些激发档案专业思想、战略及方法的概念,其次又着重阐述了档案鉴定这个由档案工作者从人类文献记录中挑选出很小比例作为档案长久保存的过程。19世纪至今的档案工作者对其工作、职能、活动及社会作用的认识经历了(或者说显示了)四个大的思想框架(或范式),探讨和了解这个背景可以让我们更好地认识和应对我们现在所处的这个数字时代的挑战。 相似文献

With this research, we sought to establish the accuracy of stride velocity data collected by the s3 Stride Sensor Participants walked along a GAITRite mat at self-selected slow, preferred, and fast velocities, with two s3 Stride Sensors attached to their right foot. The start position was systematically varied such that the GAITRite system would record the second through sixth strides at each walking velocity. Both slow and preferred walking velocities were underestimated by 14% relative to the GAITRite (p < .05), while independent of walking velocity, Strides 2 and 3 were underestimated by 26% and 9% (p < .05), respectively. Researchers should use caution when interpreting data collected at slow and preferred walking velocities and during the first three strides. 相似文献

Research Findings: There is growing acknowledgment of the need for parenting interventions to address early-onset behavior and emotional concerns. Favorable child outcomes have been linked to parents’ responsiveness and positive expressiveness. Given the theoretical and empirical link between perceptions and actual behavior, Head Start mothers (n = 114) participated in an investigation to examine factors that may be associated with level of self-reported maternal expressiveness. Participants completed the Self-Expressiveness in the Family Questionnaire (Halberstadt, Cassidy, Stifter, Parke, & Fox, 1995). Analysis suggested that self-reported high negative expressiveness was linked with raising a preschooler with perceived internalizing and externalizing behaviors, high parenting stress, and obtaining a post–high school degree. A perceived view of being low in positive expressiveness, in contrast, correlated with different variables, including raising a preschooler with a diagnosed delay, not having any child receive specialized services, raising only 1 child, dropping out of high school, and not receiving behavior advice from Head Start staff. Practice or Policy: Implications for examining self-reported low positive and high negative expressiveness as separate constructs with possibly different intervention pathways are discussed. 相似文献

In this study, we identified 10 sexuality education programmes from different locations in the USA that aim to give young people knowledge and skills to develop healthy relationships, as well as avoid pregnancy and disease. We conducted in-depth interviews with programme administrators to develop a series of case studies and provide concrete recommendations for education and public health professionals to implement similar approaches in their communities. Many programme administrators succeeded in developing partnerships, adapting existing curricula to suit their environments, engaging external evaluators and garnering support from teachers and parents. However, few programme developers conducted formal needs assessments before developing programmes and many struggled to implement curricula with fidelity and to employ rigorous evaluation designs. Nearly all participants identified concerns over funding as a threat to sustainability. We conclude that schools and organisations need technical assistance to build capacity for rigorous programme planning, implementation and evaluation, as well as additional funding streams to support emerging programmes. 相似文献

To address the need for more clinical anatomy training in residency education, many postgraduate programs have implemented structured anatomy courses into their curriculum. Consensus often does not exist on specific content and level of detail of the content that should be included in such curricula. This article describes the use of the Delphi method to identify clinically relevant content to incorporate in a musculoskeletal anatomy curriculum for Physical Medicine and Rehabilitation (PM&R) residents. A two round modified Delphi involving PM&R experts was used to establish the curricular content. The anatomical structures and clinical conditions presented to the expert group were compiled using multiple sources: clinical musculoskeletal anatomy cases from the PM&R residency program at the University of Toronto; consultation with PM&R experts; and textbooks. In each round, experts rated the importance of each curricular item to PM&R residency education using a five‐point Likert scale. Internal consistency (Cronbach's alpha) was used to determine consensus at the end of each round and agreement scores were used as an outcome measure to determine the content to include in the curriculum. The overall internal consistency in both rounds was 0.99. A total of 37 physiatrists from across Canada participated and the overall response rate over two rounds was 97%. The initial curricular list consisted of 361 items. After the second iteration, the list was reduced by 44%. By using a national consensus method we were able to objectively determine the relevant anatomical structures and clinical musculoskeletal conditions important in daily PM&R practice.

This essay is a preliminary assessment of David Bearman as the leading archival thinker of the late twentieth century. Bearman has revolutionized thinking in archival circles around the world by offering a defence of traditional archival notions of provenance, evidence, recordness, and contextuality that equals the noblest statements of a Hilary Jenkinson, and by positing a relevant, dynamic, engaged future for archivists to transform the Information Age into a Record-Keeping Age. The essay is both a personal reflection and critical analysis. There are three main themes: an assessment of Bearman's ideas and their overall importance to general archival theory; a more specific exposition of the nature and importance of the University of Pittsburgh Project and of where Bearman sees that its results are leading archivists and their profession and institutions in future; and a critique of some of the implications, if not the conscious intentions, of his ideas and methods that seem to exclude the cultural, historical, and heritage dimensions and uses of archives, public or private. The overall aim of the essay is to push the archival discourse to the next stage by challenging and constructively critiquing as well as extolling the work of this archival pioneer. 相似文献
