At a time when digital games are becoming much more commonly used in classrooms, this book provides a much-needed guide to different forms and applications of digital game-based learning. The book brings together researchers and practitioners from around the world who share their theories, strategies, findings of case studies, and practical approaches to support better performance and learning outcomes when learning with digital games. This book is intended to provide readers with three main parts of information. One is a clear and practical understanding of theory and research-based principles of game-based learning. This first section of the book includes fresh perspectives and an overview of existing and emerging theories in game-based learning, which are also presented in the form of case study findings and implications. The second section of this book gives readers the how to information needed to turn the understanding of intellectual grounding into effective practices of digital games for classroom use. The third part of this book also includes some practical approaches for evaluating different aspects of learning within the game-based learning context. This information about practical approaches is presented through chapters on achievements and performance outcomes. Game-Based Learning: Theory, Strategies, and Performance Outcomes synthesizes arguments, practices, and research findings on the effectiveness of different designs and approaches within game-based learning practices. But, a major message of this book is that the joint influence of implementation, context, and learner characteristics interacting with digital games is what determines learning and achievement outcomes. This book is intended for researchers, practitioners, designers, policy makers, and current and future teachers. The teacher/-educator will benefit from topics such as practical strategies to improve student performance, while researchers can use the findings from the case studies presented in this book as a foundation for future explorations and research studies.
