This study examined the effects of social influences in the lives of an ethnically diverse sample of fifth through eighth grade students with and without learning disabilities (LD) using survey data and academic achievement scores collected in 19 Chicago public schools from 1993–1997. Similarities and differences in student perceptions of school, family, and peer group contexts were examined. In addition, longitudinal data were analyzed using hierarchical linear modeling (HLM) to identify contextual influences on changes in student reading achievement over time. Comparisons of student responses confirm and extend existing findings in the literature concerning the perceptions of students with LD of their social environments. In particular, having a learning disability was associated with consistent, mostly negative, effects on social relations across the contexts of students’ lives, regardless of gender, race, grade, and socioeconomic status. In addition, student perceptions of their friendship groups were found to have small, but significant, effects on their growth in reading achievement over the course of middle school. While students with and without LD had somewhat different views of their social contexts, the processes working within these environments appeared to affect their reading achievement in similar ways. The results suggest that careful attention should be paid to the social contexts of students’ lives when planning academic interventions.  相似文献

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

This paper offers an overview, both internationally and with a particular concentration on the UK, of how the profession‐orientated discipline of publishing studies (PS) is accommodated and established within those universities where it is offered. It presents a combination of data, gained from a survey of professionals teaching PS, desk research into courses of PS in the UK, and from Heidi and HESA. The findings offer information on the size of the field, the location, the employability of graduates and associated staffing and research support structures. While of interest to publishing studies per se, it should also be relevant to those working within other profession‐orientated disciplines; to those considering the employability of graduating students; and to those considering the value of postgraduate studies.  相似文献

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

This article, which examines variables affecting scores on a test of library skills, finds that the frequency with which students receive assignments requiring library research is the best predictor of a score. The unevenness is students' research skills has implications for bibliographic instruction.  相似文献
