Hypertext Planning Grant

这是一项少数群体研究启动（MRI）计划拨款。本研究将探讨与技能水平相关的超文本可用性的三个问题。所采取的方法将通过长时间的学习问题来评估浏览活动期间的表现，作为技能发展的功能。通过在超文本系统中嵌入专家-导师/顾问来监控学生的进步，研究通过新的控制机制来改进超文本的使用。适当的控制量将作为用户技能和子群体（高控制寻求者与低控制寻求者）的函数进行研究。最后一个方面是研究不同的用户如何浏览超文本文档。具体来说，是否存在针对不同策略、风格、技能或动机的用户所采取的可识别路径或策略。

This is a minority research initiation (MRI) planning grant. The research will investigate three issues in the usability of hypertext related to skill level. The approach to be taken will address the learning issue by long durations to assess performance during browsing activities as a function of skill development. Improvement in hypertext usage via new control mechanisms will be studied by embedding an expert-tutor/advisor within the hypertext system to monitor student progress. The proper amount of control will be studied as a function of user skill and subgroups (high-control seekers versus low-control seekers). The final aspect is to study how different users navigate a hypertext document. Specifically, are there identifiable paths or strategies taken for users with different strategies, styles, skills or motivations.
