Learning Log Navigator : Augmented Awareness Past Learning Experiences Kousuke Mouri, Hiroaki Ogata, Mengmeng Li, Bin Hou, Noriko Uosaki The University of Tokushima, Japan Abstract— This paper proposes a Navigator system in ubiquitous learning log system called SCROLL(System for Capturing and Reminding Of Learning Log). Navigator system supports learning in terms of visualization of learning logs stored in SCROLL system. It informs learners of what and where other learners have learned visually and recommend other learning logs which are located close to them and navigate them to the recommended logs. By letting them aware of other learning logs around them and guide to show them where they are located, it provides them more opportunities to learn from experience where they can make discoveries through first-hand observations, instead of reading or hearing about the knowledge. It is thus expected to lead learners to gain more knowledge. Keywords-mobile learning; learning log; learning experience I. INTRODUCTION In recent years, the world smartphones market is growing rapidly [1]. Early smartphones were devices that mainly combined the functions of a personal digital assistant (PDA) and a mobile phone. Emergence of mobile phones and PDAs along with wireless technology allowed on-line communication in various places such as on campus, at home, train stations or airports. The functions of the smartphones have been expanded thanks to the evolution of the technology and now they came equipped with a multi-touch interface, a full browser, GPS, an acceleration sensor and so on. With these useful features added, smartphones have been gaining their popularity. Thus ubiquitous environment has been realized. It lead to a growth of ubiquitous and mobile learning environment which has been drawing researchers’ attention these days as an effective learning method to improve learners’ various abilities [2]. The ubiquitous learning environment includes the CSUL (Computer Supported Ubiquitous Learning). CSUL takes place in variety of learning spaces such as classrooms, home and museums. It provides learners with various information using the contextual data like location (Longitude and Latitude), surrounding objects, temperature and so on [3]. We have developed SCROLL (System for Capturing and Reminding of Learning Log). It provides learners with ULLs (ubiquitous learning logs) in order to let them learn knowledge or skills from experience in their daily lives. The goals of SCROLL are lying in helping users to record easily their learning experiences and recall them via their surrounding contexts, and recommending other learners' learning experiences, finding out individuals' learning habits and supporting their learning in accordance with personal learning habits [4]. This research proposes a Navigator system to fulfill the goals of SCROLL. Navigator system informs learners of what and where other learners have learned visually and recommend other learning logs which are located close to them and navigate them to the recommended logs. By letting them aware of other learning logs around them and guide to show them where they are located, it provides them more opportunities to learn from experience where they can make discoveries through first-hand observations, instead of reading or hearing about the knowledge. It is thus expected to lead learners to gain more knowledge. The rest of the paper is organized as follows. After introducing SCROLL in Section 2, we detail the proposed Navigator system in Section 3. Finally, we provide a conclusion of this study and some ideas for future works in Section 4. II. SCROLL In recent years, our lives have been changed rapidly with the evolution of the mobile devices. For example, we used to take notes when we study or work (Figure 1). We take notes for reviewing what we have learned. However, the form of note taking has been changed due to the emergence of various kinds of mobile devices. We can capture what we have learned by photos or videos instead of note taking. We call each piece of knowledge we have learned a learning log. Many researches have focused on facilitating this kind of “informal note” taking such as [5], [6]. Learning log in this paper is defined as a recorded from of knowledge or learning experience acquired in our daily lives. SCROLL is based on a learning cycle called LORE (Log-Organize-Recall-Evaluate) and it consists of four basic elements: (1) Log: When a learner faces a problem in the daily life, s/he may learn some knowledge by him/herself, or ask others for a help in terms of questions. The system records what s/he learned during this process as a ULLO (ubiquitous learning log object). (2) Organize: When a learner tries to add a ULLO, the system compares it with other ULLOs, categorizes it and shows the similar ULLOs if exist. By matching similar objects, the knowledge structure can be regulated and organized. (3) Recall: A learner may forget what s/he has learned before. Rehearsal and practice can help him/her to recall past ULLOs and to shift them from short-term memory to long- term one. Therefore, the system assigns some quizzes and reminds the learner of past ULLOs. (4) Evaluate: It is important to recognize what and how the learner has learned by analyzing the past ULLOs, so that s/he can improve what and how to learn in the future. Therefore, the system refines and adapts the organization of the ULLOs based on the learners’ evaluation and reflection [3]. Learning processes with SCROLL are shown by Figure 2 and 3.
