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

为了指导大量的时间、精力和金钱的投资，决策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还没有从无处不在的计算计划的评估中得到。 SRI国际正在与六个伙伴组织合作，开发一个通用框架，用于评估无处不在的计算对K-12数学和科学教育的影响。该框架基于为其他目的开发的现有框架（例如，该项目的目的是澄清决策者的信息需求及其对无处不在的计算的期望。来自SRI国际、Metiri集团、弗吉尼亚大学、明尼苏达大学、ROCKMAN等、EDC儿童与技术中心的经验丰富的评估人员，和肯特州立大学的教育技术研究中心也在作为独立的组织对几个州的许多无处不在的计算计划进行评估。该组织开发的框架将用于加强个人评估，并使其更好地满足决策者的需求。通过使用一个框架，在其中的各种重要的评估问题的影响，无处不在的计算对数学和科学教育，我们可以框架和理解，大大增加了知识的机会，将积累。项目组公布的框架，评估结果，并综合这些结果在一个项目的网站。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。还通过会议介绍和期刊文章传播信息。邀请其他评估人员、政策制定者和从业人员使用这些产品，这些产品旨在帮助加强普适计算领域的评估工作。通过评估，更好地了解正在进行的无处不在的计算举措，预计将导致使用教育技术的数学和科学教育实践的改进。

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.
