During simulation-based training, people (instructors as well as participants) interact with one another, the equipment and the environment in a goal-oriented way. The social character of simulation influences how, and what meaning, the people involved assign to the simulation: do they focus on the potentials of simulation or the boundaries? Do they accept the simulation as a learning setting, relevant for their daily tasks, or do they feel that it has nothing to offer them? This book looks at using simulation, focusing on acute medical care settings but also looking beyond this thematic framework. Drawing on theoretical frameworks and empirical data, the authors describe how simulation can be used for the analysis of training needs, as well as designing and conducting goal-oriented and ecologically valid simulation settings. The book is aimed at researchers and practitioners who are interested in improving their use of simulation by basing their practice on sound theoretical underpinnings and empirically derived optimising strategies. The content addresses different forms and settings of simulation and simulation tools used.
