Structured document retrieval makes use of document components as the basis of the retrieval process, rather than complete documents. The inherent relationships between these components make it vital to support users’ natural browsing behaviour in order to offer effective and efficient access to structured documents. This paper examines the concept of best entry points, which are document components from which the user can browse to obtain optimal access to relevant document components. It investigates at the types of best entry points in structured document retrieval, and their usage and effectiveness in real information search tasks. 相似文献

When public catalog users enter queries that exactly match the catalog's controlled vocabulary, online systems should respond with browsing lists of alphabetically arranged subject headings, because such displays guide users to retrievals based on the assignment of the matched subject headings to bibliographic records. Unfortunately, studies of online catalog searching demonstrate that alphabetical displays are no longer capable of managing large numbers of subdivided forms of subject headings, because searchers exhibit low levels of perseverance when faced with large numbers of retrievals. This paper introduces a new approach to displaying retrieved subject headings in subject searching—the exact-display approach—designed to encourage users to browse bibliographic information. The purpose of this paper is to emphasize the importance of the exact-display approach by showing how many user queries would be candidates for this approach, demonstrate an implementation of the exact-display approach in an experimental online catalog, and feature end-user experiences with this approach as implemented in the experimental catalog. End-user experiences gave the authors the opportunity to make several recommendations for enhancing the original design of the exact-display approach so that future implementations of this approach in operational online catalogs are responsive to the needs of online catalog users. 相似文献

This article explores whether struggling readers from different primary language backgrounds differ in response to phonologically based remediation. Following random assignment to one of three reading interventions or to a special education reading control program, reading and reading-related outcomes of 166 struggling readers were assessed before, during, and following 105 intervention hours. Struggling readers met criteria for reading disability, were below average in oral language and verbal skills, and varied in English as a first language (EFL) versus English-language learner (ELL) status. The research-based interventions proved superior to the special education control on both reading outcomes and rate of growth. No differences were revealed for children of EFL or ELL status in intervention outcomes or growth during intervention. Oral language abilities at entry were highly predictive of final outcomes and of reading growth during intervention, with greater language impairment being associated with greater growth. 相似文献

This study investigated the developmental changes in the contributions of comprehension ability and the meta‐cognitive control of several study strategies (selection, memory, monitoring) to competence in studying among average and above‐average seventh and eleventh‐grade students. Results indicated that the ability to comprehend and meta‐cognitive control of study strategies were related to the recall of information at both ages. However, meta‐cognitive control was clearly more important to the older students than it was to the younger students. These data suggest that future research on the development of studying should focus on students’ use of the strategies of memory and monitoring. 相似文献

A set of students who had been accepted at a particular university was examined to determine the factors influencing a student's decision to enroll at that school. A gravity model predicted that distance is an important determinant of the enrollment decision. The student's ability level, by influencing the student's other options, also was expected to have an impact on the decision. Logit analysis confirmed these predictions. While other variables, such as family income and program of study, may have an impact on earlier stages of the college selection decision, those variables do not influence the final stage of that decision. 相似文献

Differences in College Access and Choice Among Racial/Ethnic Groups: Identifying Continuing Barriers
Hurtado Sylvia Inkelas Karen Kurotsuchi Briggs Charlotte Rhee Byung-Shik 《Research in higher education》1997,38(1):43-75
This study focuses on the college application behaviors of students from various racial/ethnic groups in order to understand differences in access and college choice. Student characteristics, predispositions, academic abilities, and income levels were taken into account in our analyses. We analyzed data from the National Education Longitudinal Study (NELS) and the Beginning Postsecondary Student Longitudinal Study (BPS) and found significant group differences in preparation behaviors, college application behavior (number of colleges to which students applied), and attendance at their first choice of institution. The results of this study call attention to the need for campuses to evaluate the potential effects of policy decisions that may impact student choice for different populations of students. 相似文献

Residence halls at large institutions are increasingly becoming sites for powerful undergraduate learning experiences. A study of living‐learning programs at four research universities—the prelude to a nationwide project—tells an important story. 相似文献
