The main topic of this chapter is about a pervasive learning at workplace, namely, work-based learning. Our proposition is based on two complementary learning strategies: situation-based learning and activity-based learning to fulfill seamless learning across contexts and worked-based learning requirements. In situation-based learning, relevant activities and/or resources are recommended to the user. In activity-based learning, the user has to search and to select his/her activities and the corresponding resources. These strategies correspond to two different information dissemination approaches that can be distinguished, namely push and pull (Cheverst, Mitchell, & Davies, 1998). We propose a pervasive learning environment where learners may follow different learning strategies. They may switch from one strategy to the other one according to their needs and/or the context change. These facilities are possible thanks to a set of models and adaptation processes developed for the P-LearNet project (Pervasive Learning Network). To illustrate this proposal, an example (or a use case) from this project is used. The chapter is organized as follows: we introduce some issues of technology-enhanced learning systems and define mobile, pervasive and ubiquitous learning and some closely related features: context, adaptation, situated learning, working and learning activities. Secondly, Work-based learning features are described. Thirdly, situation-based and activity-based learning strategies are presented. Finally, the P-LearNet project is used to illustrate the proposal and the conclusion summarizes the chapter and shows how and at which level this framework can be reused.
