This paper motivates contextualized media for learning and starts with a reference model for describing and analysing contextualized media applications for learning. Based on a more detailed analysis of the context dimension and contextual parameters taken into account when supporting mobile and ubiquitous learning a technical framework and its components are presented. The framework allows to model and implement complex educational scenarios for contextualized learning and integrates different components and layers necessary. As an example application “ContextBlogger” is described which implements contextualized blogging support based on APIs of standard blogging systems and different context sensors as GPS and Semacode. The paper concludes with an outlook on possible chances and challenges for future research.
