The use of mobile learning has provided new pedagogical approaches to teaching geometry as a result of the technological affordances provided. One of the key affordances of mobile learning is the portability of the devices. This has untethered the learner from a particular environment to learn wherever and whenever the learner chooses. This chapter describes a subcategory of mobile learning called context-aware ubiquitous learning (context-aware ulearning) where learning happens in a real-world environment while using mobile devices to interact with that setting. This chapter delineates this subcategory and how this type of learning can be dichotomized into sensory and ambient context-aware ulearning. An argument is made that context-aware ulearning is a useful pedagogical approach for learning geometry.
