Of course, there are drawbacks to the observation process. For example, students observing and imitating other student behavior can be detrimental for an in-world class. BecauseSecond Life is a world where residents rule, there are no definitive rules about behavioral expectations. Student behavior in an in-world class can be unpredictable, and undesirable to instructors and other students. If students observe undesirable behavior it has the potential to be repeated. The idea of self-control is important here (see for example, Dewey, 1939; Martin, Burger, Elias-Burger & Mithaug, 1988). Imagine a student (avatar) coming to class naked. How about students slumping over in class (this happens when an avatar is inactive for a period of time)? Not all behavior is acceptable in Second Life. However, the benefits can outweigh the disadvantages. Such problems are usually easily fixed by teachers taking initiative and composing a set of classroom rules (such as: “do not come to class naked”) for their students.
