This paper describes the design and the use of computer supported ubiquitous learning environments. First, this paper mentions context-aware language-learning support systems for learning vocabularies, mimicry and onomatopoeia, polite expressions, and conversational expressions by leveraging PDA, GPS, RFID tags and sensor networks. Second, it describes a web-based video repository for sharing and retrieving learning experiences. This system was used in the scenarios of computer hardware assembling and cooking. Finally, the paper is ended with the discussions and future works.
