A Framework and Network for Evaluating the Impact of Ubiquitous Computing in K-12 Schools

为了指导大量时间、精力和金钱的投资，政策制定者需要更多关于教育技术影响的证据，但对他们有用的信息尚未从无处不在的计算倡议的评估中获得。SRI国际正在与六个伙伴组织合作，为评估普适计算对K-12数学和科学教育的影响制定一个共同框架。该框架基于为其他目的开发的现有框架(例如，由北中区教育实验室和梅蒂里集团开发的Engauge模型)和为该项目进行的政策研究的结果，该政策研究旨在澄清政策制定者对普适计算的信息需求和期望。来自SRI国际、梅蒂里集团、弗吉尼亚大学、明尼苏达大学、Rockman等人、EDC儿童与技术中心和肯特州立大学教育技术研究中心的经验丰富的评估员也作为单独的组织对几个州的许多无处不在的计算倡议进行评估。该组织将开发的框架将用于加强个人评估，使其更好地响应政策制定者的需求。通过使用一个框架，可以框架和理解关于普适计算对数学和科学教育的影响的各种重要评估问题，我们极大地增加了知识积累的机会。项目团队正在将框架、评估结果和这些结果的综合发布在项目网站上。此外，正在开发一些新的评价工具，这些工具也将通过网络提供。还通过会议发言和期刊文章传播信息。邀请其他评估者、政策制定者和实践者使用这些产品中的任何一种，这些产品旨在帮助加强泛在计算领域的评估工作。通过评估更好地了解正在进行的普适计算倡议，预计将有助于改进使用教育技术的数学和科学教育实践。

To guide large investments of time, effort, and money, policymakers need more evidence about the impacts of educational technology, but little information useful to them has yet been derived from evaluations of ubiquitous computing initiatives. SRI International is working with six partner organizations to develop a common framework for evaluating the impacts of ubiquitous computing on K-12 mathematics and science education.The framework is based on existing frameworks developed for other purposes (e.g., the EnGauge model developed by North Central Regional Educational Laboratory and the Metiri Group) and on findings from a policy study conducted for this project designed to clarify policymakers information needs and their expectations about ubiquitous computing. Experienced evaluators from SRI International, the Metiri Group, the University of Virginia, the University of Minnesota, ROCKMAN ET AL, EDC's Center for Children and Technology, and Kent State University's Research Center for Educational Technology are also working as separate organizations conducting evaluations of many ubiquitous computing initiatives in several states.The framework to be developed by the group will be used to strengthen the individual evaluations and make them more responsive to policymakers' needs. By using a framework in which a variety of important evaluation questions about the impacts of ubiquitous computing on mathematics and science education can be framed and understood, we greatly increase the chances that knowledge will accumulate.The project team is posting the framework, evaluation findings, and syntheses of these findings on a project Web site. In addition, a number of new evaluation tools are being developed, and these, too, will be available through the Web. Information is also being disseminated through conference presentations and journal articles. Other evaluators, policy-makers, and practitioners are invited to make use of any of these products, which are intended to help strengthen evaluation work in the field of ubiquitous computing. A better understanding of ongoing ubiquitous computing initiatives, derived from evaluations, is expected to lead to improvements in mathematics and science education practices that use educational technology.
