在之前的工作中，我们报告了一个社会注释系统的设计，SparTag.us，用于意义建构活动，如工作组阅读和报告写作。以前的笔记系统的研究已经证明了行为差异的社会注释的做法，但不清楚的实际性能增益提供的社会功能。本文提出了一种实验室研究，旨在评估Spartag.us的社会功能的学习效果。我们发现了显着的学习收益，并考虑设计和理解的基本机制，当人们使用社会注释系统的影响。
In prior work we reported on the design of a social annotation system, SparTag.us, for use in sensemaking activities such as work-group reading and report writing. Previous studies of note-taking systems have demonstrated behavioral differences in social annotation practices, but are not clear in the actual performance gains provided by social features. This paper presents a laboratory study aimed at evaluating the learning effect of social features in SparTag.us. We found significant learning gains, and consider implications for design and for understanding the underlying mechanisms in play when people use social annotation systems.
