Book Description
This book presents various video processing methodologies that are useful for distance education. The motivation is to devise new multimedia technologies that are suitable for better representation of instructional videos by exploiting the temporal redundancies present in the original video. This solves many of the issues related to the memory and bandwidth limitation of lecture videos. The various methods described in the book focus on a key-frame based approach which is used to time shrink, repackage and retarget instructional videos. All the methods need a preprocessing step of shot detection and recognition, which is separately given as a chapter. We find those frames which are well-written and distinct as key-frames. A super-resolution based image enhancement scheme is suggested for refining the key-frames for better legibility. These key-frames, along with the audio and a meta-data for the mutual linkage among various media components form a repackaged lecture video, which on a programmed playback, render an estimate of the original video but at a substantially compressed form. The book also presents a legibility retentive retargeting of this instructional media on mobile devices with limited display size. All these technologies contribute to the enhancement of the outreach of distance education programs. Distance education is now a big business with an annual turnover of over 10-12 billion dollars. We expect this to increase rapidly. Use of the proposed technology will help deliver educational videos to those who are less endowed in terms of network bandwidth availability and to those everywhere who are even on a move by delivering it effectively to mobile handsets (including PDAs). Thus, technology developers, practitioners, and content providers will find the material very useful.

Book Description
Digital learning proves that the digital revolution has almost no limits in the world. The extension of e-learning to digital learning has completely changed training and learning habits. In universities and companies and even at home, anytime and anywhere, innovative e-learning tools, such as online videos, e-learning quizzes, interactive games, and digital learning courses, can enhance knowledge exchange. The Handbook of Research on Scripting, Media Coverage, and Implementation of E-Learning Training in LMS Platforms considers the design and development of management systems, learner profiles, learning activities, and e-learning projects and discusses the design, development, and implementation in an LMS platform of e-learning projects based on educational engineering models. Covering key topics such as teaching practices, distance learning, and artificial intelligence, this reference work is ideal for industry professionals, administrators, policymakers, researchers, academicians, scholars, instructors, and students.

Book Description
Beyond Open Distance Learning is not about the advances made in distance education through the use of modern communication technologies and educational pedagogies (OECs, MOOCs, web, YouTube, Twitter, etc). The book is more about the discussion on the need for new thinking (disruptive innovations) for a more holistic development or Kuhonian revolution. It discusses ways to try to escape from the cocoon we created in ODL and higher education and to move towards new horizons of a sustainable and balanced development of the society.

Book Description
Although video is now ubiquitous in education, its full potential is oftentimes not fully understood, nor is it used to utmost potential. This timely volume seeks to address this gap by providing educators and instructional designers with a comprehensive and in-depth understanding of video production processes and methods for designing effective instructional videos. From its discussion of the significance of digital learning and impact of instructional video to its unique focus on the best design and production techniques that make video an effective teaching tool, this book offers applicable and tested strategies for creating quality instructional video. The accompanying website, which allows readers to see sample videos and access additional online resources, underscores the book’s practitioner focus. Among the topics covered: · Instructional videos for teaching and learning · Design and interactivity of instructional videos · Production, distribution, and integration of instructional videos · The future of instructional video Video in the Age of Digital Learning is an important, practical contribution to the scholarship exploring methods for sharing and acquiring knowledge in the digital age. It promises to be a valuable resource for educators, instructional designers, instructional media producers, and educational technology professionals.

Book Description
'I would like to enthusiastically recommend The SAGE Handbook of E-Learning Research. An international set of authors have produced a highly readable handbook that covers topics in E-learning research, theory, policy, language and literacy, and design issues. The work draws on multiple perspectives ranging from early work in asynchronous learning networks to community organization in e-learning. This is a large and much needed work that organizes and illuminates issues in E-learning in a way that readers will be able to take away practical advice for their own use. I am quite pleased to see this handbook that provides a very useful organization of knowledge for our field' - John Bourne, Ph.D Professor and Executive Director, The Sloan Consortium (www.sloan-c.org) 'This book is an important contribution to the development of E-learning because its account of the research always begins with the context of learning from which the exploitation of technology can be viewed. The authors help us understand that technology affords new kinds of relationship between the learner and what is learned, and how it is learned. With this rich understanding, the book is able to build the wide-ranging research foundation on which the field can move forward' - Diana Laurillard, Institute of Education, University of London 'A comprehensive and compelling resource that provides a global perspective on a development that is transforming higher education' - David Pilsbury, Chief Executive, Worldwide Universities Network 'Unlike many how-to books on the topic...this work focuses on research for educators and others interested in how technology enhances or diminishes learning. Highly Recommended' - Choice Magazine This handbook provides a state-of-the-art, in-depth account of research in the rapidly expanding field of E-learning. The first of its kind, it provides reviews of over 20 areas in E-learning research by experts in the field, and provides a critical account of the best work to date. The contributors cover the basics of the discipline, as well as new theoretical perspectives. Areas of research covered by the Handbook include: - Contexts for researching e-learning - Theory and policy - Language and literacy - Design issues - History of the field The editors' introduction and many of the chapters show how multiple aspects of E-learning interact. The introduction also provides a new model for researching the field. This book is relevant for everyone in higher education, from undergraduate to faculty, as well as university administrators involved in providing E-learning. It will provide a research background for higher education, including universities, training colleges, and community colleges. It will also be relevant to those involved in any research and developmental aspect of E-learning - corporate trainers and those involved in online programs at secondary school or in virtual high schools. Whether you are a lecturer, researcher or programme designer, this is an essential read. Richard Andrews is Professor in English at the Institute of Education, University of London and Visiting Professor at New York University's Steinhardt School of Education, Culture and Human Development. Caroline Haythornthwaite is Associate Professor at the Graduate School of Library and Information Science at the University of Illinois at Urbana-Champaign.
