This scholarly book in SIOP’s Organizational Frontier series looks at research on enhancing knowledge acquisition and its application in organizations. It concentrates on training, design and delivery given the changing nature of work and organizations. Now that work is increasingly complex, there is greater emphasis on expertise and cognitive skills. Advances in technology such as computer simulations and web-based training are necessitating a more active role for the learner in the training process. In the broad context of the organization systems, this book promotes learning and development as a continuous lifelong endeavor.
