With the resources provided by communication technologies, E-learning has been employed in multiple universities, as well as in wide range of training centers and schools. This book presents a structured collection of chapters, dealing with the subject and stressing the importance of E-learning. It shows the evolution of E-learning, with discussion about tools, methodologies, improvements and new possibilities for long-distance learning. The book is divided into three sections and their respective chapters refer to three macro areas. The first section of the book covers methodologies and tools applied for E-learning, considering collaborative methodologies and specific environments. The second section is about E-learning assessment, highlighting studies about E-learning features and evaluations for different methodologies. The last section deals with the new developments in E-learning, emphasizing subjects like knowledge building in virtual environments, new proposals for architectures in tutoring systems, and case studies. Contents include: (1) Wikis and Blogs in E-Learning Context (Teodora Bakardjieva and Boyka Gradinarova); (2) XML Data Access via MOODLE Platform (Aleksandra Werner and Katarzyna Harezlak); (3) E-Learning Tools as Means for Improving the Teaching-Learning Relation (Augustin Prodan, Paulina Mitrea, Madalina Rusu, Cornelia Revnic and Remus Campean); (4) Methods and Tools for Increasing the Effectiveness of E-Learning (Donika Valcheva and Margarita Todorova); (5) Technological Transparency in the Age of Web 2.0: A Case Study of Interactions in Internet-Based Forums (Kamran Shaikh, Vivek Venkatesh, Tieja Thomas, Kathryn Urbaniak, Timothy Gallant, David I.
