Second life is basically a virtual world. You can create your own avatar to interact with other avatars. You can create groups to gather people of common interest, or simply socialise with others. Lecturers can build structures that make the virtual world more like the real world, e.g. build the lecture room.
It runs through the internet making it accessible worldwide. Lecturers may pre-record the lecture and stream the lectures to the students, allowing them to focus more on the questions asked. This would also allow the lecturer to ensure all points are covered, and anything they missed can then be addressed live.
Other activities on second life, such as DJ-ing, can engage “residents” (the term for users of second life) more onto second life. This would lead to more time being spent on second life and residents becoming more accessible to other residents. Students and lecturers can then interact more than just during the “lecture”.
