In prior work we report on the design of a social annotation system, SparTag.us, for use in sensemaking activities such as work group reading and report writing. Other studies of note-taking systems find 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 a significant effect in learning gains, and consider its implications for design and the underlying mechanisms in play in social annotation systems.
