Technology development, primarily for telecommunications and computer systems, played a key role in the interactivity and, thus, for the expansion of e-learning. This book gives suggestions for dealing with challenges of e-learning, opening new paths of learning and conferring new methodologies to expand the conversing level of classes, and implementing technical tools for aiding students to make improvised use of e-learning resources. The book is divided into sections that talk about the necessary infrastructure for e-learning models and processes, organizational practices, suggestions, implementation of methods for assessing results, case studies targeted on pedagogical aspects that can be implemented generically in diverse environments, and tools that can be adopted by users, for instance, graphic tools for engineering, mobile phone networks, and techniques to build robots. Also, some portions in the book focus specifically on e-learning areas like engineering and architecture.
