Ubiquitous Contextual Access to STEM Educational Resources (UCASTER)

正在开发基于标准的Internet Explorer、Mozilla Firefox和Google Chrome扩展，以便随时从任何网页提供对NSDL资源的上下文化和教育相关的访问; 2）使开放教育资源的开发人员能够创建适应用户上下文的应用程序; 3）通过使用户了解可能的合作者来促进同学和朋友之间的合作。这一努力通过结合和推广现有和正在使用的技术，推动了在线学习。 浏览器扩展在浏览器中显示为一个按钮，可从任何网页使用。 迷你门户包括（a）与页面内容和用户教育水平相关的关键术语，（B）诸如Jmol、Mathlets和Physlets之类的“应用程序”，其可用于探索页面上的主题，以及（c）指向最近查看过相同页面或相关主题的同事和朋友的指针。滚动一个术语将显示一个定义，单击一个术语将检索相关的NSDL资源。

Standards based extensions to Internet Explorer, Mozilla Firefox and Google Chrome are being developed to provide contextualized and educationally relevant access to NSDL resources from any web page at any time; 2) to enable developers of open education resources to create apps that adapt to a user's context; 3) to facilitate collaboration among classmates and friends by making users aware of likely collaborators. The effort is resulting in an advance in online learning by combining and extending technologies that are in place and in use. The browser extension appears as a button in the browser and is available from any web page. The mini-portal includes (a) key terms relevant to the content of the page and the user's educational level, (b) "apps" such as Jmol, Mathlets, and Physlets that can be used to explore topics on the page, and (c) pointers to colleagues and friends who have recently looked at the same page or related topics. Rolling over a term brings up a definition and clicking on a term retrieves relevant NSDL resources.
