This paper uses case studies to focus on distance learning in developing countries as an enabler for economic development and poverty reduction. To provide perspective, we first review the history of telecottages, local technology-equipped facilities to foster community-based learning, which have evolved into “telecenters” or “Community Learning Centers” (CLCs). Second, we describe extensive site visits to CLCs in impoverished portions of China and Mexico, the centers operated by premier universities in each respective country. These CLCs constitute the core of new emerging systems of distance education, and their newness poses challenges and opportunities, which are discussed. Finally, we offer 12 points to develop further the concept and reality of distance learning in support of economic development.  相似文献

Subscores are often used to indicate test‐takers' relative strengths and weaknesses and so help focus remediation. But a subscore is not worth reporting if it is too unreliable to believe or if it contains no information that is not already contained in the total score. It is possible, through the use of a simple linear equation provided in this note, to determine if a particular subscore adds enough value to be worth reporting.  相似文献

ABSTRACT

This article considers a project that used the Social Return on Investment (SROI) methodology to describe and measure the social impact of Turner Contemporary art gallery in Margate, a coastal town in the South East of England. The article details the reasons why the methodology was chosen by the gallery, setting this in the context of the wider debate around evaluation and social impact reporting. A section of the research and analysis, which was carried out by COaST, a consultancy and research centre based within Canterbury Christ Church University, is described in detail, allowing the reader to understand the processes involved in this type of project and the kinds of outcomes that can be delivered using this method. Finally, an account is given of the impact the work had on the management of the gallery, and the ways in which the final report was used.  相似文献

Subscores can be of diagnostic value for tests that cover multiple underlying traits. Some items require knowledge or ability that spans more than a single trait. It is thus natural for such items to be included on more than a single subscore. Subscores only have value if they are reliable enough to justify conclusions drawn from them and if they contain information about the examinee that is distinct from what is in the total test score. In this study we show, for a broad range of conditions of item overlap on subscores, that the value of the subscore is always improved through the removal of such items.  相似文献

The author examines the empirical, methodological, theoretical, and practical contributions of the six studies in this special issue on eye tracking as a tool to study and enhance multimedia learning. The design of learning environments involving graphics should be consistent with a research-based theory of how people learn and evidence-based principles of how to help people learn. Research using eye tracking offers a unique path to testing aspects of theories of multimedia learning, particularly concerning perceptual processing during learning. The studies reported in this special issue add to the evidence base on how people learn and think with graphics.  相似文献

When developing case studies within a longitudinal study of special educational needs provision within the Republic of Ireland, the authors were conscious of the critiques of the use of this approach within educational research. The difficulties associated with generalisation, challenges of ensuring trustworthiness and the possibilities of researcher bias have been identified as limiting factors in the presentation of case study data. In order to confront these limitations, the researchers developed a framework for case study development that aimed to provide a secure database and trustworthy interpretation in order to make assertions in relation to special educational needs provision. This paper describes this process and suggests that the need to develop safeguards in order to present case studies that have high degree of credibility is essential when using this approach. Furthermore, the transparency of research methods, a significant omission in many reports of research, is necessary in order to demonstrate the trustworthiness of data.  相似文献
