Do a sound check at the beginning of every lesson. Do not assume everybody can hear you just because they could last time. You do not want a student to ask you to repeat all that you said after they finally realised you were talking but they couldn’t hear. If you know from the beginning that some students cannot hear you or others, you can, for example, use local chat more.
Personally, if students cannot hear me due to technical problems, I will try to and write as much as I can into local chat to accommodate them. If, however, I have announced that the course will be in voice but students have not set it up, I do not help them during the lesson.
That’s why having one session before the actual course is a good idea or, at least, sending students to places where they can get help (tutorials). Another option, if you possible, is to have a technical assistant, at least in the first couple of lessons and only at the beginning of a lesson, say the first 15 minutes. Students can then be told to IM the assistant for technical help.
A general rule:
Activities in Second Life usually take longer than in Real Life for many reasons. Take this into consideration when planning lessons or adapting RL lessons to SL. After you have attended or taught several lessons, you will get a feel for it and timing will become easier. Keeping lessons plan flexible will also help you (more on this in another tip).
Do not have students shout out answers in voice when you work as a whole class in larger classes. It is very difficult to hear who is saying what even if you know the voices of your students. The quality of voice also differs greatly depending on SL that day, on bandwidth, on the qualitiy of the participants microphone, etc.
1. Have students write in local chat (eg. T or a student asks in a game: Which is the longest river of the world?) All students type in their answers in to local chat as fast as they can. This way everybody has the same chance and it is easy to see who was first.
2. If you have “hand show chairs“, which are available in-world for free”, use these. Students who sit on these chairs can raise their hand by simply clicking on one key on their keyboards and everybody can see who raises their hand.
I do prefer the first option, though, as it is easier and can be done everywhere without having to set up or rez any objects.
