As teacher we can wonder about the learning potential of Second Life: What are the characteristics of Second Life as learning environment? What are the benefits for pupils? What are the implications for trainers? And last, how to use Second Life as a learning tool? And what feels students in a course on designing and learning activities in Second Life? What are the feelings and emotions that we will have to take into account when designing a training action in Second Life? If we have been students before teachers, we will have much of the path done... Reflections those raised in the online course on "Design of learning activities, Web 2.0 and second life” where a web comic was used to engage students and where a student sent a web comic as response. The best of this: it wasn’t an activity.
