Collaborative Research: Developing a Learner-Centered Metathesaurus for Science, Mathematics, Engineering and Technology Education

这个合作项目（与加州伯克利大学的人员合作）正在研究基于对学习者和两个学习资源（数学论坛和www.smete.org）之间的交易分析来创建以学习者为中心的元词典。正在考虑三种交互模式。第一个是许多学生回答同一个问题的数据（数学论坛上的“本周问题”）。第二种交互模式涉及学习者和专家之间的交易数据（数学论坛的“问数学博士”功能）。研究中的最后一种international模式使用第三种资源www.smete.org上的集合，学习者的使用更多地是在传统的图书馆搜索-检索模式中。以查看和选择的资源的形式的附加反馈信息使得能够在学习者的语言和资源元数据之间构建映射，这具有允许跨域边界扩展元词库的潜力。

This collaborative project (with personnel at the University of California Berkeley) is investigating the creation of a learner-centered metathesaurus based on the analysis of transactions between learners and two learning resources - the Math Forum and www.smete.org. Three modes of interaction are being considered. The first involves data in which many students respond to the same problem (the "Problem of the Week" at the Math Forum). The second interactional mode involves data from transactions between learners and experts (the Math Forum's "Ask Dr. Math" feature). The final interactional mode under study uses collections at a third resource, www.smete.org, where learner usage is more in the traditional library mode of search-retrieve. Additional feedback information in the form of the viewed and selected resources enables the construction of a map between the learners' language and resource metadata, which has potential to permit the extension of the metathesaurus across domain boundaries.
