Dear All, My name is Andrea. I am a Brazilian Ph.D. candidate, based in London for the current year. I was addressed to this list by my advisor: Michel Menou. My work deals with the changes brought to learning processes by the switch from real to virtual spaces. A special concern in this respect is the formation of critical and autonomous thinkers. The concept of critical thinkers seems a great umbrella. But for me it is less a matter of fostering individual skills and more a social interaction process, which promote a collective questioning, criticism and creativity. I am fostering interesting examples of pedagogical practices. I believe I will find good clues on dialogical methods, such as discussions and collaborative learning, but it's not a "straitjacket". I am also interested in experiences that create and/or maintain community interaction. Does it ring any bells to any of you? I would either appreciate indications of related research and publications. Thanks in advance, Andrea Lapa a.b.lapa@soi.city.ac.uk
