L3T is the short form for the award-winning and freely accessible "Textbook for Learning and Teaching with Technologies" (http://l3t.eu). In summer 2013, the book was completely revised and expanded as part of the "L3T 2.0" project. A new approach was taken: within seven days, from 20 to 28 August 2013, the book was revised or newly created in L3T camps and via online communication and collaboration in German-speaking Europe. The new edition also allows modifications of the texts, so it can be used even more flexibly in teaching.
This book describes how the project "L3T 2.0" proceeded and which tasks were distributed. In addition, the results of an interim and final survey of the 268 participants are presented in detail. Finally, the (self-) evaluation leads to the formulation of recommendations for imitators. The book is of interest to all those who are looking for experiences and reports in the field of open educational resources, book prints or open book projects in order to be inspired for their own projects.
