Book excerpt: Let evidence guide your training. Your training is much more effective when your methods are based on evidence. In this third edition of Evidence-Based Training Methods, Ruth Colvin Clark offers concrete training guidance as she connects research to practice. This book is rich with examples of how research enhances training, and with it as your guide, you can incorporate evidence and learning psychology into your program design, development, and delivery decisions. New in this edition, Clark examines research on feedback with application tips for training as well as on using animations in critical thinking exercises. Games have also inspired a great deal of recent research, leading to updated information about which ones are effective and why. Ultimately, Clark advises focusing on instructional methods that are relatively inexpensive to implement and offers simple, effective changes.
