Information access is central to library and information science, yet explorations of its conceptual nature have been limited. Given the importance of information access to the discipline, there is a need for research to create a better understanding of the concept and its many roles in all activities and behaviors related to information. Drawing on the theoretical work of Elfreda Chatman, this article proposes that the study of information access can be facilitated through the recognition and examination of the physical, intellectual, and social aspects of information access. These types of access are examined through three case studies in terms of different information behaviors and contexts, with a particular focus on the importance of social access. The article also discusses the future roles that considerations of social access can play in research and theory.  相似文献

Public libraries have been seen to have an important role in providing digital services to potentially excluded groups in order to help meet government targets regarding the delivery of digital services. Geographical information systems (GIS) have been used to investigate library service areas, to aid initial location decisions, and to model the implications of the opening and closure of library services. Recent studies have promoted the use of GIS-based techniques to investigate spatial variations in accessibility to public and private services in relation to socio-economic characteristics of population groups. One such technique, based on floating catchment area (FCA) approaches, has been primarily used to investigate potential inequalities in health services, access to employment and leisure opportunities, as well as planning public transport. In this study, FCA techniques are used to research variations in accessibility to public library facilities using bespoke application tools developed within a commercial GIS package. Drawing on a preliminary analysis of variations in accessibility to library services in a local authority area in south Wales, UK, a case study is presented whereby GIS-based models can be used to investigate spatial variations in digital services provision. As a result, provision gaps of such services can be identified. This study's findings help guide national government delivery programs to promote digital inclusion.  相似文献

School reform strategies involving restructuring require that administrators redefine their roles. Most of the research in this area has emphasized new rather than veteran administrators. However, if these reform strategies are to be implemented, school administrators at mid‐career stages will need to change their conceptions of the role.

This article identifies and examines literature concerning the major issues of socialization to a role conception, including definitions, sources, and socialization mechanisms for changing conceptions of the role. The article also presents a research agenda based on this theoretical examination that delineates research questions, relevant variables, and possible findings regarding changing role conceptions. The research agenda focuses on two major strategies of educational reform: shared decision making and schools of choice.  相似文献

In this study, we investigate the effect of reading purpose on students’ processing behavior during a reading comprehension test. In a repeated measures design, sixty undergraduates answered multiple-choice (MC) reading comprehension questions in a condition with no overarching goal for reading and in an alternate condition where the same students were first provided with the goal of summarizing the text before answering MC questions. Results from eye tracking analysis showed that when students read and answered questions without an overarching goal, they spent much less time reading the passages before answering the questions, more time re-reading the texts while answering the questions, and more time on parts of the text that were not necessary to answer the questions. We conclude that providing examinees without an explicit goal for reading may inadvertently encourage a “search for the answer” reading process, rather than on building a coherent mental model of text content.  相似文献

Comparing the admissions selectivity of colleges on the basis of accept rates can be misleading because the quality of the applicant pool is ignored. However, many rate comparisons can be improved using the demographic technique of direct standardization. In this study, SAT-specific accept rates for about 200 private four-year colleges and universities in the United States were estimated and used to compute adjusted (standardized) accept rates. College-bound high school seniors who took the SAT verbal and mathematics examinations in 1986 formed the standard populations. Standard errors for the differences in adjusted accept rates between colleges were computed so that selectivity groupings of colleges could be constructed. Results showed that selectivity rankings changed substantially depending on whether crude or adjusted accept rates were used. Adjusted rates reduced the problems of comparing admissions selectivity among colleges whose applicant quality varied significantly.  相似文献

Although information technology is increasingly used to deliver distance and conventional courses, there have been few studies of the effect of technology-enhanced education on the organization and purposes of academics’ instructional work. I explore this issue in undergraduate and masters level education through the vehicle of case analyses of technology-rich classes taught in a public research university in the United States. What the cases illustrate is an emergent pattern of what I am calling ‘Mode III’ instructional production, in which the production of a course involves a matrix of non-faculty support personnel, and may be oriented to commercial purposes reflective of an increasingly embedded academic capitalism in the new economy.

We investigated the impact of introducing college students to complex adaptive systems on their subsequent mental models of evolution compared to those of students taught in the same manner but with no reference to complex systems. The students' mental models (derived from similarity ratings of 12 evolutionary terms using the pathfinder algorithm) were significantly similar to their teachers' mental models and were correlated to their performance on an essay on evolution. Introducing students to complex systems facilitated their understanding of the mechanism of inheritance, the mechanism of evolution, and the role of chance in evolution.  相似文献

The connection between language and reading is well established across many languages studied to date. Little is known, however, about the role of language in reading in Arabic??a Semitic language characterized by diglossia??in which the oral and written varieties differ across language components. This study examined the relationship among multiple components of language, namely, phonology, morphology, and vocabulary and reading outcomes in 83 bilingual English-Arabic children. Results revealed associations between phonological awareness skills across English and Arabic. These associations did not hold for morphological awareness skills. Results also revealed that for Arabic and English, phonological awareness predicted word and pseudoword reading accuracy and vocabulary predicted reading comprehension. These findings are consistent with the tenets of the extended version of the Triangle Model of reading, which underscores the importance of multiple language components in predicting reading outcomes. Implications for future research, early intervention, and instruction with bilingual children are highlighted.  相似文献

This study investigates four variations of a microtechnology process and its effect on the development of cooperative behavior in 96 third grade children. Subjects were randomly assigned to one of four treatment groups. The treatments were the complete microtechnology process and three variations of the process. Findings suggest that: cooperative behavior can be significantly (p < .01) increased by use of microtechnology techniques; the microtechnology process is effective without the self-confrontation component; and the behavior developed exhibited short-term retention.  相似文献
