Visualization and analysis system for connecting relationships of learning logs

In recent years, ubiquitous learning systems based on CSUL (Computer Supported Ubiquitous Learning) and u-learning have been constructed using ubiquitous technologies such as mobile devices, RFID tags, QR codes and wireless networks. These types of learning takes place not only in-class learning but also in a variety of out-class learning spaces such as home, library and museum. However, learning materials provided by ubiquitous learning systems are in most cases, prepared by teachers or instructional designers. It makes it difficult to find relationships between a learner and other learners in different contexts. In order to link learners in the real world and learning logs that are accumulated in a cyber space by a ubiquitous learning system called SCROLL (System for Capturing and Reminding of Learning Log), this paper proposes a visualization and analysis system called VASCORLL (Visualization and Analysis system for COnnecting Relationships of Learning Logs). Using VASCORLL, learners can find other contexts where can be applied to their own learning experiences. The initial evaluation was conducted to examine whether VASCORLL can increase learners' learning opportunities and learners can apply their own experiences to different contexts.
