In the last years, we have witnessed significant advances in technology, which have not only changed our world but also become part of modern life. And like any other aspect of our lives, our work in the field of Languages for Specific Purposes (LSP) has also been transformed by technology, especially by the use of computers in our daily tasks as teachers and researchers. The purpose of this volume is to offer an overview of an ample variety of applications of IT in the field of LSP. It is addressed to a wide audience that includes LSP teachers and researchers, although the contents may also be relevant to applied linguists working in other fields. This book contains research studies as well as educational experiences and proposals, presented from different perspectives and backgrounds (both geographical and cultural), all of which are theoretically grounded and with a clear and sound rationale. Thus, the reader will find a variety of educational projects and research studies situated in specific educational contexts and in particular geographical locations. Although not intended for generalization, they are valuable technology-based educational solutions that offer new insight and reflections that will help readers create their own tools and carry out further research. For this reason, the book focuses on central topics that have awakened the interest of LSP professionals. In turn, this thematic selection has helped us organize the chapters into related sections covering the main areas of research and practice in the field.
