Social Media and Web 2.0 are currently a buzz in the society. Everybody wants to participate, everybody wants to use it - not online besides class but alos as a part of it. Society is changig permanently and therefore also the way teachers teach. For the current generation of teachers the question is not if e-learning should be included into the educational establishment, the question is simply how to integrate online applications like Wiki or blogs into the classroom. The situation for the lecturer is a complicated one. His conventional role does not include the usage of technologies but the paradigm change makes it necessary. The lecturer role includes, maybe more than ever, the role as a knowledge manager. In our current society, lecturer and student are already used to the computer, the internet and various applications. Students are used to social networks like Facebook or MySpace and blogs to create their own content. The potential of these services can and will be used for class and beyond. The goal of this book is to analyze the usage of blogs during class and to try to evaluate what should be done...and what eventually better not!
