Today, the online sphere is no longer just an information repository or a place to search for resources. It has become instead a place supporting both intentional and non-intentional learning. Intentional, formal learning, often leads to certification, whereas informal learning is unstructured and takes place as part of daily work-related or leisure activities. Cases on Formal and Informal E-Learning Environments: Opportunities and Practices brings together cases outlining the practical aspect of formal, non-formal, and informal online learning. This book introduces conceptual aspects of these types of learning, knowledge-base, new learning paradigms, policy implications, evaluation and concerns, design, and development of online learning.
