A context-aware ubiquitous (u)-learning case is presented to demonstrate how it can be used in real-life contexts. Yang and co-researchers identify eight major characteristics of context-aware u-learning, namely mobility, location, interoperability, seamlessness, situation awareness, social awareness, adaptability and pervasiveness. Each student has a handheld mobile device equipped with an RFID reader. In the learning area, wireless communication is provided, so that the mobile device can communicate with a computer server. As a student moves around the learning area, the system can detect their location by reading and analyzing the data from the nearest RFID tag. If the student fails to correctly identify some feature of the plant, the test system will guide the student to identify it. After comparing the correct leaf shape with the misidentified one, the student is asked to answer the question again.
