This study explored preschool teachers' beliefs about the appropriateness of early literacy and mathematics education. In all, 60 teachers of 4-year-olds, half working with low-socioeconomic status (SES) children at publicly funded preschools and the other half with middle-SES children at private preschools, were randomly assigned to read either the mathematics or the literacy versions of written vignettes describing issues related to teaching these subjects. Teachers were interviewed individually concerning the vignettes. Analyses showed that teachers of middle-SES children tended to support literacy and mathematics education that respects individual children and their preferences and to oppose classroom use of computers; overall they emphasized nonacademic areas. Teachers of low-SES children tended to focus on literacy and mathematics to prepare children for kindergarten and to support computer use; they showed concern about their students' underdeveloped readiness to learn, particularly literacy. Analyses comparing subject matter showed that for literacy, teachers preferred to gear a curriculum toward children's interests and to allow children to follow their interests in a literacy-rich classroom to promote social competence and positive dispositions toward literacy. For mathematics, teachers preferred to embed mathematics into everyday routines to promote the learning of key knowledge and skills throughout the day. These findings have significant implications for professional development. 相似文献

The FCC's proposal for Universal Service Fund (USF) reform proposes to replace current universal service funding programs with the Connect America Fund (CAF), a fund devoted to using government support to make broadband service available in un-served or under-served geographical locations. The goal is to maximize the bang-per-buck from available funds by looking at incremental upgrades to existing infrastructure in under-served areas and incremental infrastructure build-outs in un-served areas. The strategy is to encourage competition between broadband providers whether they are wireless providers or wireline providers. 相似文献

This paper describes a methodology for the development of a proactive balanced scorecard (PBSCM). The balanced scorecard is one of the most popular approaches developed in the field of performance measurement. However, in spite of its reputation, there are issues that require further research. The present research addresses the problems of the balanced scorecard by utilizing the soft computing characteristics of fuzzy cognitive maps (FCMs). By using FCMs, the proposed methodology generates a dynamic network of interconnected key performance indicators (KPIs), simulates each KPI with imprecise relationships and quantifies the impact of each KPI to other KPIs in order to adjust targets of performance. 相似文献

This paper presents system design challenges and issues with sensing through walls at different standoff distances and wall types. Efforts for developing sense through the wall (STTW) systems, such as those undertaken by the US Army Technology Objective (ATO) program, aim at providing the soldier with situational awareness information before breaching a building in a military operations in urban terrain (MOUT) environment. STTW capabilities also support law enforcement and search and rescue applications. Since 2002, extensive evaluations of STTW technologies, most notably those performed by the Communications Electronics, Research, Development and Engineering Center (CERDEC) Intelligence and Information Warfare Directorate (I2WD), have been made to determine which technology could be the most viable solution. After conducting comprehensive studies, I2WD initiated several Phase I efforts and Phase II efforts. The purpose behind both efforts was to develop various STTW technology demonstrators under a 5 year ATO. Many lessons learned during the development of Phase I systems were incorporated into the considerations for Phase II developments. This paper discusses design challenges and issues with sensing through walls at different standoff distances and wall types through lessons learned and results from modeling and simulations performed by the Army Research Laboratory. 相似文献

否定副词"莫"从上古发展到中古,在功能上发生了调整:魏晋南北朝时期否定副词"莫"用例明显增加,不仅可以用来表示一般否定,而且可以表示禁止否定.这一调整是内外因相互作用的结果. "莫"之所以能够发展成为否定副词,最根本的原因就是由于无定代词"莫"具备了转化成为否定副词的内在因素:语义上,无定代词"莫"意为"没有谁"或"没有什么"; "莫"的句法位置有可能引起重新分析;副词的修饰限制作用进一步促进了否定词"莫"的产生. 相似文献

This paper presents a literature review of empirical research related to the use and effect of online social annotation (SA) tools in higher education settings. SA technology is an emerging educational technology that has not yet been extensively used and examined in education. As such, the research focusing on this technology is still very limited. The literature review has aimed at presenting a comprehensive list of SA empirical studies not limited to a particular research method or study domain. Out of more than 90 articles that were initially found, only 16 studies met the inclusion criteria. Among the included studies were eight experimental or quasi-experimental studies and eight evaluation/survey studies. The SA empirical research has provided some evidence regarding the potential effectiveness of integrating social annotation tools into learning activities. Findings from the gathered literature were synthesized to provide recommendations for using SA technology in educational settings. 相似文献

A survey of the use of ethnographic methods in the study of libraries and library users 总被引:1,自引:0,他引:1
Michael Khoo Lily RozaklisAuthor VitaeCatherine HallAuthor Vitae 《Library & information science research》2012
A survey and analysis of the use of ethnographic methods in studies of libraries and library users identified a total of 81 studies. Five main types of ethnographic research methods were identified: observation, interviews, fieldwork, focus groups, and cultural probes. The survey shows a recent increase in the use of ethnographic methods in libraries, and identifies an emerging genre of studies associated with library planning that uses rapid ethnographic methods to investigate libraries and their users as part of planning processes. The survey supports comparison across ethnographic studies, settings, and methods; enables the growth of ethnographic methods as a research method in libraries; and provides material for library and information science curriculum development in this area. A bibliography of the studies used in the analysis is provided in Appendix A, and includes a number of gray literature reports and online publications. 相似文献
