One of the challenges of CSUL (Computer Supported Ubiquitous Learning) research is capturing what learners have learned with the contextual data, and reminding the learners of it in the right place and the right time. This paper proposes a ubiquitous learning log system called SCROLL (System for Capturing and Reminding Of Learning Log). Ubiquitous Learning Log (ULL) is defined as a digital record of what learners have learned in the daily life using ubiquitous technologies. It allows the learners to log their learning experiences with photos, audios, videos, location, QR-code, RFID tag, and sensor data, and to share and to reuse ULL with others. Using SCROLL, they can receive personalized quizzes and answers for their questions. Also, they can navigate and be aware of their past ULLs supported by augmented reality view. This paper also describes how SCROLL can be used in different contexts such as learning analytics for Japanese language learning, seamless language learning, and museum.
