Lurking: an underestimated human-computer phenomenon

In this article, the authors offer their perspective about online learning. In general, we know that online learning develops through interaction and that it's a collaborative process where students actively engage in writing and reading messages among themselves and with the instructor. However, it's also well known that in any online community, not all users are equally active, and there are indeed people who never take an active part-the so-called lurkers. This article focuses on the lurkers; the authors ran extensive experiments to demonstrate whether there's a relationship between the writing and reading behavior of online students and whether active participation influences learning efficiency. An interesting related result that emerged from the study is that the effort of the instructor in terms of reading and writing posts is higher than that of the learners themselves.
