Despite efforts have been invested in using digital technologies to enhance learners' language learning, rarely explored are studies aiming at bridging in-class vocabulary learning with real-life learning experiences in primary school education. This study aims at investigating what primary students learned by linking in-class and real life English vocabulary learning mediated by a mobile learner-generated content (m-LGC) tool; and what students' perception of the m-LGC use was. Case study approach was adopted. Data collection included student created learning logs and questionnaire. Both qualitative and quantitative methods were used to analyze data. The results show that students not only were able to apply the newly learned vocabulary to real life, but also were able to learn from peers about the vocabulary, and related culture. In the meantime, issues were identified, and future work is explored.

This paper focuses on the problem of language transfer in foreign language learning. The transfer caused by the difference between learner's mother language and target language, often leads a communicative gap. This paper first analyzes the semantic relations between learner's mother language and target language. Then proposes a CGM (Communicative Gap Model) due to language difference. We have developed a communicative language-learning environment called Neckle (Network-based Communicative Kanji Learning Environment) to support foreign language learning through communication with native speakers. Neckle has a software agent that observes the conversation between the learner and the native speaker, checks up the communicative gap according to CGM, and notices the gap for the support of language learning congenial to each learner. Learners can not only be aware of the language difference but also acquire its cultural background from the native speakers.

This paper describes an online markup-based collaborative writing environment system called CoCoAJ (Communicative Collection Assisting System for Java). It allows authors and editors to exchange marked-up documents via Internet, and it s environment is very similar to a real world one in which people use pen and paper. In order to record and exchange corrected compositions with marks and comments, this paper proposes XCCML (eXtensible Communicative Correction Markup Language), that is based on XML (eXtensible Markup Language). XCCML facilitates editors to analyze and reuse the marked-up documents for the instruction.

This paper proposes an open-ended and collaborative learning environment, called SharlokII. In this environment, the learners provide and share individual knowledge and other knowledge on the World Wide Web and discuss about them. This paper describes knowledge awareness map and its design, implementation and evaluation. The map visualizes the relationship between the shared knowledge and the current and past interactions of learners. The map plays a very important role of finding peer helpers, and inducing collaboration. In this map, a mediator agent recommends suitable collaborators who can help the problem solving. SharlokII has been developed and used it experimentally.

This paper proposes a framework for AVC (Asynchronous Virtual Classroom) that allows each learner to communicate with others in a classroom at anytime. Many seminar-typed VC systems to solve the geographical distance problem have been studied. However, most of them are limited with the necessity of time-sharing. Therefore, we focused on the solution of its time-sharing problem by means of asynchronous learning environment with video and simulative discussion. In these environments, a learner is able to refer the learning material or the past discussions, to communicate with others at anytime, and to make notes of the lecture with the personal/shared notebook tool. The system accumulates and manages these interactions in order to reuse for later learners. In this way, AVC system encourages both individual and collaborative learning. Especially in this paper, we describe our framework and its prototype system.

CoCoA (Communicative Correction Assistant System) was developed for supporting students and teachers to exchange online marked-up documents via email. Its environment is very similar to a real one in which people use paper and pen. In order to effectively reuse marked-up digital documents created with CoCoA, this paper proposes a computer supported proofreading exercise environment called CoCoA2. CoCoA2 can reduce the overload of the teacher, and it can make composition learning more effective. CoCoA2 has been developed and used it experimentally.

Knowledge awareness (KA) has been proposed for increasing collaboration opportunities in an open ended and collaborative learning environment. KA consists of information about up-to-minute activities of other learners. For instance, it indicates when someone is looking at the same knowledge that learners are looking at. Multiple collaboration is concurrently realized through KA. This paper describes a concurrent collaborative learning environment supported by awareness called Coconuts, toward augmenting participation in collaborative learning. We tested and verified the effectiveness of Coconuts in an experimental training.

Knowledge awareness (KA) has been proposed for increasing collaboration opportunities in an open ended and collaborative learning environment. To enhance the opportunities of collaboration in this situation, an individual user's agent called KA-Agent autonomously informs the learner up-to-minute other learners' activities. For instance, the messages are "someone is looking at the same knowledge that you are looking at.", "someone discussed the knowledge which you have inputted". Those messages are called active KA ,which are very useful to create real-time collaboration within the shared knowledge space. The spontaneous collaboration which is created by these messages, facilitates the refinement and evolution of the learners' knowledge. Sharlok (sharing, linking and looking-for knowledge) has been developed as a testbed of the KA. We reached the following conclusion by the test use of Sharlok: (1) In order to stabilize learners' knowledge, it is very important for learners to discuss with each other; (2) Active KA is very effective for encouraging collaboration between learners; and (3) KA supports learners to realize real-time collaboration. However, many messages of active KA are provided at the same time because several learners use some knowledge in a shared knowledge space. Such a big amount of massages are often inadequate to confuse learners and to disturb their learning. The problem is to define how KA-Agent should give a priority to the messages. Therefore, the agent has to have an information filtering facility to inform a learner only the important part of KA. This paper describes filtering awareness so that awareness should not disturb to engage in learning. To reduce information overload, the technologies of information filtering are mainly used in reading E-mail or NetNews. In this paper, we propose KA filtering based on some educational strategies toward efficient collaborative learning. KA-Agent has two strategies based on the following criteria: (1) whether or not the messages of KA disturb to engages in learning; and (2) whether or not the messages of KA can create effective collaboration.

This paper describes a computer mediated language learning environment called CoCoA (Commutative Collection Assisting System) that supports students and teachers to exchange marked-up documents via Internet. Its environment is very similar to a real one in which people use paper an pen. CoCoA allows teachers not only to correct the compositions sent from foreigners by E-mail, but also learners to see where and why the teacher corrected them. CoCoA improves the opportunities that foreigners have for writing Japanese compositions and for receiving instructions from teachers. In order to record and exchange corrected compositions with some marks and some comments, this paper also proposes CCML (Communicative Correction Markup Language), which is based on SGML (Standard Generalized Markup Language). We have developed CoCoA and used it for verifying its effectiveness.

In this paper, we present an ontology-based visualization support system which can provide a meaningful learning environment to help e-book learners to effectively construct their knowledge frameworks. In this personalized visualization support system, learners are encouraged to actively locate new knowledge in their own knowledge framework and check the logical consistency of their ideas for clearing up misunderstandings; on the other hand, instructors will be able to decide the group distribution for collaborative learning activities based on the knowledge structure of learners. For facilitating those visualization supports, a method to semi-automatically construct a course-centered ontology to describe the required information in a map structure is presented. To automatically manipulate this course-centered ontology to provide visualization learning supports, a prototype system is designed and developed.

A Ubiquitous Learning Log (ULL) is defined as a digital record of what a learner has learned in daily life using ubiquitous computing technologies. In this paper, a project which developed a system called SCROLL (System for Capturing and Reusing Of Learning Log) is presented. The aim of developing SCROLL is to help learners record, organize, recall and evaluate ULLs. Using SCROLL, learners can not only receive personalized quizzes and answers to the questions, but also navigate and be aware of their past ULLs supported by augmented reality views. In particular, this paper introduces an approach that helps learners record their learning experiences in daily life from life-log photos with the help of SenseCam. To evaluate the effectiveness of this system, a case study of an undergraduate English course is presented to show how it can be used to facilitate seamless learning.

This paper presents the integration of ubiquitous computing systems into classroom settings, in order to provide basic support for classrooms and field activities. We have developed web application components using Java technology and configured a classroom with wireless network access and a web camera for our purposes. In this classroom, the students interact among each other and with the professor through an Internet-enabled personal digital assistant (PDA), using the different modules described in this paper. We include our evaluations about the performance and usability of the system in a computer science related course of the University of Tokushima, other practical uses including outdoor learning activities, and future research and development work.

Ubiquitous computing will help in the organization and mediation of social interactions wherever and whenever these situations might occur. With those technologies, learning environment can be embedded in daily real life. Especially, RFID (Radio Frequency Identification) tags are very useful and important technology to realize ubiquitous computing, because they enable to bridge real objects and information in a virtual world. RFID tags will be embeded in a lot of physical objects in the near futre in order to trace the products shipping, and so forth. Then, this paper proposes a computer-assisted language learning (CALL) using RFID tags, which is called TANGO (Tag Added learNinG Objects). TANGO detects the objects around the learner using RFID tags, and asks the learner the appropriate questions for vocaburaly learning in daily life with PDA. RFID

This paper proposes a ubiquitous learning environment that supports daily learning at the right time and at the right place (RTRP) in ubiquitous computing environments. Especially , it is said that language is acquired in everyday learning (outside school) rather than using dictionaries and textbooks (inside school). Therefore, this paper proposes a computer-supported ubiquitous language learning environment called CLUE (Collaborative-Learning support-system in Ubiquitous computing Environments). CLUE consists of three subsystems. The first system supports sentence learning, which provides the useful expressions at the right place at the right time. The second system helps polite expression learning. In Japan, there are four levels of polite expressions. This system provides the right level of politeness , deriving from personal information of another person and user's situation. The final system supports learning vocabulary, which detects the objects around learner using RFID tag, and provides the learner the right information at the moment. This paper describes the implementation and experimentation of those systems.

This paper describes Knowledge Awareness (KA), a new concept for inducing collaboration in an open ended and collaborative learning environment. To enhance collaboration opportunities in this situation, KA provides information about the activities of the learners within the shared knowledge space. For instance, the messages are "someone is looking at the same knowledge that you are looking at," "someone discussed the knowledge which you have inputted." The spontaneous collaboration that is created by the messages facilitates the refinement and evolution of the learners' knowledge. This paper also describes knowledge awareness map and its design, implementation and evaluation. The map visualizes the relationship between the shared knowledge and the current and past interactions of learners. The map plays a very important role of finding peer helpers, and inducing collaboration. In this map, a mediator agent recommends suitable collaborators who can help the problem solving. SHARLOK II (sharing, linking and looking-for knowledge) has been developed on the web as a testbed of KA map, which has a knowledge building and collaborative learning environment connected via Internet. We have tested and verified the effectiveness of SHARLOK II and KA map through their use.

The pedagogical attempts of nowadays can be seen throughout the networked environment using video image as a learning material. They aim at proposing anywhere/anytime learning environment. In addition to the static learning materials like on-demand video images with some slides, our system combines them with a dynamic transformed materials, which are implemented as the results of asynchronous communication. This function drives at the increase of the opportunity of participants' interaction. Yet, we can easily imagine a problem under such precondition that asynchronous users may participate in the system from the In-ternet without spatial, time and social restriction. The problem is that it is difficult for the system to synchronize all the collaboration accumulated in the past participants' interaction with video if the number of learners on such open-ended environment gets larger and larger. Therefore, this paper describes methodologies to develop an adaptive filtering outcomes of the past collaboration, to realize the way to synchronize them with the on-demand learning materials. Finally, the paper summarizes the experimental results to show the validity of our approach.

It is a common practice to issue a summary of a learner's learning achievements in form of a transcript or certificate. However, detailed information on the depth of learning and how learning or teachings were conducted is not present in the transcript of scores. This work presents the first practical implementation of a new platform for keeping track of learning achievements beyond transcripts and certificates. This is achieved by maintaining digital hashes of learning activities and managing access rights through the use of smart contracts on the blockchain. The blockchain of learning logs (BOLL) is a platform that enable learners to move their learning records from one institution to another in a secure and verifiable format. This primarily solves the cold-start problem faced by learning data analytic platforms when trying to offer personalized experience to new learners. BOLL enables existing learning data analytic platforms to access the learning logs from other institutions with the permission of the learners and/or institution who originally have ownership of the logs. The main contribution of this paper is to investigate how learning records could be connected across institutions using BOLL. We present an overview of how the implementation has been carried out, discuss resource requirements, and compare the advantages BOLL has over other similar tools.

The aim of this research is to measure self-regulated behavior and identify significant behavioral indicators in computer-assisted language learning courses. The behavioral measures were based on log data from 2454 freshman university students from Art and Science departments for 1 year. These measures reflected the degree of self-regulation, including anti-procrastination, irregularity of study interval, and pacing. Clustering analysis was conducted to identify typical patterns of learning pace, and hierarchical regression analysis was performed to examine significant behavioral indicators in the online course. The results of learning pace clustering analysis revealed that the final course point average in different clusters increased with the number of completed quizzes, and students who had procrastination behavior were more likely to achieve lower final course points. Furthermore, the number of completed quizzes and study interval irregularity were strong predictors of course performance in the regression model. It clearly indicated the importance of self-regulation skill, in particular completion of assigned tasks and regular learning.

Learning takes place in a variety of different environments, both in-class as of formal learning and outside as informal learning. Seamless learning offers the opportunity to learn in different environments regardless of location or time. Students can benefit from learning in many contexts, and it can also provide insights for teachers into how learning is being conducted in informal situations outside the classroom. Previous work into the analysis of seamless learning has mainly focused on purpose build specialized systems that provide an environment for a specific task. In recent years, the field of learning analytics has been growing and learning environments are increasingly being developed across different modular systems that are linked together by standards-based protocols. In order to analyze seamless learning on a larger scale, this paper proposes the integration of an informal learning system, SCROLL, into a wider modular system. The proposed system addresses fundamental problems, such as the protection of user privacy and authentication while increasing the availability of data for analysis from other learning systems. We also examine the ability to analyze and visualize learning across numerous environments and contexts.

Authentic learning experiences are considered to be a rich source for learning foreign vocabulary. Prevalent learning theories support the idea of learning from others' authentic experiences. This study aims at developing a learning analytics solution to deliver the right authentic learning contents created by one learner to others in a seamless learning environment. Therefore, a conceptual framework is proposed to close the loops in the missing components of the current learning analytics framework. Data is captured and recorded centrally via a context-aware ubiquitous learning system which is a key component of a learning analytics framework. k-Nearest Neighbor (kNN) based profiling is used to measure the similarity of learners' profiles. Authentic learning contents are shared and reused through re-logging function. This paper also discusses how two previously developed tools, namely learning log navigator and a three-layer architecture for mapping learners' knowledge-level, are adapted to enhance the performance of the conceptual framework.

This paper introduces a platform for image recommendation that can be used in informal learning of foreign words. The platform is based on a distributional semantics model (DSM) that is designed to recommend Feature-based Context-specific Appropriate Images (FCAIs) for representing a word. This technology is for a context-aware ubiquitous learning system that captures ubiquitous learning logs from various learning scenarios. This paper briefly discusses the data capturing tool, methods of employing learning analytics for ubiquitous learning logs analysis, natural language processing techniques applied for word-bank creation, and image embedding methods employed for feature analysis, development of an algorithm that determines the most appropriate FCAI images, and related scientific issues.

In this paper, we introduce the components of LAView, a learning dashboard that assists teachers to author criteria for different teaching-learning cases. We define indicators as the basic unit to define the status of a situation and visualise that on the dashboard. This paper describes the technology design and workflow of the teacher as the user of the dashboard from setting indicator criteria to recording reflection of their results. We conclude with the utility of such a technology support in the context of evidence-based education.

The multidisciplinary research approach of Learning Analytics (LA) has provided methods to understand learning logs collected during various teaching-learning activities and potentially enrich such experiences. This workshop aims to explore the frontiers of how technology can help to extract evidence of effective teaching-learning practices by applying the knowledge base of LA and developing novel techniques. It focuses on discussions on realizing a technology-enhanced evidence-based education and learning (TEEL) systems. We invite research articles conceptualizing foundations, methodologies and utility of TEEL systems. Further, we plan to have a focus group activity to validate an initial technical proposal of Learning Evidence Analytics Framework (LEAF) and draw a research road-map of log data-driven evidence-based education system.

Learning analytics dashboards (LAD) have supported prior finds that visualizing learning behavior helps students to reflect on their learning. We developed LAViEW, a LAD that can be easily integrated with different learning environments through LTI. In this paper, we focus on the context of eBook-based learning and present an overview of the indicators of engagement that LAView visualizes. Its integrated email widget enables the teacher to directly send personalized feedbacks to selected cohorts of students, clustered by their engagement scores. These interventions and dashboard interactions are further tracked to extract evidence of learning.

The increasing volume of student reading logs from virtual learning environment (VLE) provides opportunities for mining student' engagement pattern in digital textbook reading. In order to mine and measure students' engagement pattern, in this paper, we extract several students' reading interaction variables from the digital textbook as metrics for the measurement of reading engagement. Moreover, in order to explore the presence of subpopulation of students that can be differentiated based on their engagement patterns and academic performances, we cluster students into different groups. Students are clustered based on their reading interactions such as total session of reading, total notes adding, etc. Accordingly, we identify students' engagement patterns from different groups based on the clustering analysis results. Several student subpopulations such as low engagement high academic performances and low engagement low academic performances are identified based on students' reading interaction characteristics by clustering analysis. The obtained results can be used to provide researchers with opportunities to intervene in the specific group of students and also an optimal choice for student grouping.

To enable students to engage in lifelong learning, it would require developing self-direction skills (SDS). The use of technology in education is common, however, the available software still offers poor support from a self-direction point of view. From the theories of self-directed learning (SDL) and evidence-based practice (EBP), we proposed a framework to track self-directed actions and represent strategies of practice by the learner. This framework is one of main components of the GOAL (Goal Oriented Active Learner) system. The GOAL system is built to support for acquisition of SDS in the context of learning and health. In this paper we describe how learner interactions in the GOAL system are captured as eXperience API statements and later visualized to enable learners reflect on their strategies.

In this paper, we aimed at detecting off-task behaviors of the students by analyzing logs from a digital textbook reader. We analyzed 47 students' reading logs from a 60-minutes long in-class reading activity. During the preprocess, we extracted each student's reading patterns as a single vector. Then we used cluster analysis to find the most common reading patterns. Our results indicated that there are two major reading patterns in data. The first pattern is, the students who are following the instructor from the beginning until the end of the lecture. The second pattern is, students who are following the instructor's pattern until the first 17 th minute but not during the rest of the lecture. Based on these patterns we labeled first group as on-task students while the other group as off-task students. We also investigated academic performance of students in these two groups. Obtained results can be used to design data-driven support for in-class teaching. Instructors can plan interventions when off-task behaviors occur while the lecture is in progress.

There has been much research that demonstrates the effectiveness of using ontology to support the construction of knowledge during the learning process. However, the widespread adoption in classrooms of such methods are impeded by the amount of time and effort that is required to create and maintain an ontology by a domain expert. In this paper, we propose a system that supports the creation, management and use of knowledge maps at a learning analytics infrastructure level, integrating with existing systems to provide modeling of learning behaviors based on knowledge structures. Preliminary evaluation of the proposed text mining method to automatically create knowledge maps from digital learning materials is also reported. The process helps retain links between the nodes of the knowledge map and the original learning materials, which is fundamental to the proposed system. Links from concept nodes to other digital learning systems, such as LMS and testing systems also enable users to monitor and access lecture and test items that are relevant to concepts shown in the knowledge map portal.

As the adoption of digital learning materials in modern education systems is increasing, the analysis of reading behavior and their effect on student performance gains attention. The main motivation of this workshop is to foster research into the analysis of students' interaction with digital textbooks, and find new ways in which it can be used to inform and provide meaningful feedback to stakeholders, such as: teachers, students and researchers. In this workshop, participants analyzed the event logs from three different universities datasets with information on over 1000 students reading behaviors. Additional information on lecture schedules were also provided to enable the analysis of learning context for further insights into the preview, in-class, and review reading strategies that learners employ. Finally, workshop contributors were encouraged to implement their research results as a feature of an open LA dashboard.

In recent years, learning analytics has become a hot topic with many institutes deploying learning management systems and learning analytics tools. In this paper, we introduce learning analytics platforms that have been established in two top national Japanese universities. These initiatives are part of a broader research project into creating wide-reaching learning analytics frameworks. The aim of the project is to support education and learning through research into educational big data accumulated on these platforms. We also discuss the future direction of our research into learning analytics platforms. This includes introducing a model in which learning analytics tools and the results of research can be shared between different education institutes.

This paper introduces SCROLL dataset, a dataset that consists of foreign language learners lifelong learning experiences (i.e. lifelogs). Logs are chronologically collected from a context-aware ubiquitous language learning system called SCROLL (System for Capturing and Reminding of Learning Logs). The dataset contains ubiquitous learning logs from the period of November 2009 to March 2018 (except the years 2015 and 2016). Furthermore, we propose some baseline approaches using the provided information from the dataset. With these baselines, we target at providing references for other approaches that intends to solve problems in the domains of educational technology. The dataset can be used for educational research purposes, particularly for knowledge discovery using learning analytics and educational data mining strategies.

E-books are capable of producing a significant amount of clickstream data that insights students' learning behavior. Clickstream data are often analyzed in learning analytics and educational data mining domains to understand students' synchronous and asynchronous learning processes. The present study analyzed a dataset consisting of university students' clickstream data for predicting their final scores using machine-learning methods. To begin with, the raw data are preprocessed in four steps, namely data aggregation, feature generation, data balancing, and feature selection. After that, utilizing machine learning methods, high performing and low performing students' final scores are predicted. For this, eight machine-learning methods (Neural Network, AdaBoost, Logistic Regression; Naïve Bayes, kNN, Support Vector Machine, Random Forest, and CN2 Rule Induction) are employed and their performances were compared. Result revealed that CN2 Rule Induction algorithm having 88% accuracy outperformed other machine learning methods when best-5 selected features from the dataset were taken into consideration. However, the Multilayer Perceptron based Neural Network performed best having the similar accuracy with CN2 Rule Induction when all features were considered to predict. This paper also focuses on how SMOTE as a data balancing algorithm can be applied to solve data imbalance problem and various scoring methods can be compared to identify the most important feature attributes in clickstream.

This paper aims to develop an image recommendation system to support informal vocabulary learning for a context-aware learning environment called SCROLL (System for Capturing and Reminding of Learning Log). The idea is based on ubiquitous learning logs analysis, image (contextual and non-contextual) feature analysis, and information visualization techniques. We designed a model based on which the proposed Feature-based Context-specific Appropriate Image (FCAI) recommendation system will be developed. The purpose of recommending FCAI images is to assist language learners in informal learning of foreign vocabulary. Those images are recommended by analyzing 25350 ubiquitous learning logs (i.e. a learner's ethnographic information, learning location, learning time, learning context, image information etc.) at the right time, right place and in the right learning context-basis. This paper also articulates the approaches for ubiquitous learning logs analysis, word-bank formation, image analysis methods, and algorithm development.

This paper describes an infrastructure for seamless learning analytics to bridge digital textbook learning and practical training such as programming and conceptual modeling education. To realize the infrastructure for seamless learning analytics, we propose the integration of a digital textbook system into a software learning support system. By using our proposed infrastructure, all learning data will be sent by xAPI and collected in an independent LRS. We believe that analyzing and visualizing the relationships between the learning in the digital textbook system and practical training in the software learning support system leads to improving the quality of learning and teaching.

Currently eLearning infrastructure across various institutions often includes a Learning Management System (LMS), various ubiquitous and classroom learning tools, Learning Record Stores (LRS) and Learning Analytics Dashboards (LAD). Such an infrastructure can apply Learning Analytics (LA) methods to process log data and support various stakeholders. Teachers can refine their instructional practices, learners can enhance learning experiences and researchers can study the dynamics of the teaching-learning process with it. While LA platforms gathers and analyses the data, there is a lack of specific design framework to capture the technology-enhanced teaching-learning practices. This position paper focuses the research agenda on evidence in a data-driven educational scenario. We propose the Learning Evidence Analytics Framework (LEAF) and present the research challenges involved. 1. Background The concept of Evidence-Based Practices has its root in medicine and coined by doctors at McMaster University in Hamilton, Ontario in early 1990s (Kvernbekk T., 2017). According to Kvernbekk, EBP involves the use of the best available evidence to bring about desirable outcomes, or conversely, to prevent undesirable outcomes. Davies, P. (1999) reviews the concept of evidence-based practices in education. He proposes that evidence in the context of education needs to be established where its lacking and can be used in the following four ways: 1. Pose an answerable question about education; 2. Know where and how to find evidence systematically and comprehensively using the electronic (computer-based) and non-electronic (print) media; 3. Retrieve and read such evidence competently and undertake critical appraisal and analysis of that evidence according to agreed professional and scientific standards; 4. Organize and grade the power of this evidence and determine its relevance to their educational needs and environments. While literature takes various theoretical perspective on Evidence-based education (Davies, P. 1999), Research-based education (Hargreaves, 1996), Literature-based education (Hammersley, 1997), Context-sensitive practice (Greenhalgh and Worrall, 1997) they mostly debate about rigorous studies to establish causalities similar to medical practices. What is missing is any research agenda of how technology can support the process and relevant discussions regarding issues in the current age of data-driven education. This position paper focuses on the notion of evidence-based education in the age of e-learning. Technology now supports logging of teaching-learning (TL) interactions and Learning Analytics has matured tremendously over the period to provide robust methods to analyze and predict learning behaviors and outcomes in different TL contexts. Hence there is relevance in rethinking about the question Davies (1999) asked regarding "What is evidence?" and how the four objectives can be supported by technology. This would push the boundaries of learning analytics and move towards an evidence-based education system that can assist the various stakeholders in the teaching-learning scenarios.

For the 21 st century learner, self-direction skill is crucial for developing both intellectual abilities and maintaining one's healthy lifestyle. While there are technology supports for specific self-regulated learning tasks and health monitoring, research is limited on how to support development of the meta-skill of Self-Direction itself. Our work bridges Learning Analytics (LA) and Quantified-Self (QS) research to enable technology support for self-directed activities of learners. We propose DAPER (Data-Analyze-Plan-Execution monitoring-Reflect), a data-driven Self-Direction skill execution and acquisition model. To support synchronize-visualize-analyze multisource data regarding learners' learning and physical activities, we are developing the GOAL (Goal Oriented Active Learner) system. In this paper we present our DAPER model, the initial implementation of the GOAL system based on that model and pilot study regarding the need and context analysis of this research.

In Society 5.0, a global trend is to process educational big data in order to solve various social and educational problems. This study, leveraging the power of learning analytics intends to investigate an unsolved problem in the domain of image-based vocabulary learning, namely how to recommend context-specific appropriate images at the right time, right place and right context. The aim of this study is to develop an innovative image recommendation system that can recommend Feature-based Context-specific Appropriate Images (FCAI) by analyzing learners' previous learning records. This paper introduces a distributional semantics model for image recommendation.

My research focuses on interdisciplinary data driven approach to support students and teachers. For students, I aim to design technology interventions to develop their self-directedness skill (SDS). For teachers, I investigate how learning dashboards can facilitate adopting actionable learning analytics in teaching practices. This two-pronged research agenda uses a proposed core process model, we call DAPER model. In DAPER model, users utilize data to plan, monitor and reflect on one's practices. We are developing LET's GOAL system based on the DAPER model to support the students. The model also fits in Learning Evidence Analytics Framework (LEAF), our proposed technology framework for evidence-based education system. In this article I shall give an overview of my ongoing postdoctoral research work on data driven approach to support students and teachers. 1. Technology support for acquisition of self-direction skills Literature on 21 st century skills highlights learner's self-direction as a sub-skill. Even in a broader context self-directedness is crucial in the current society across all age groups and across contexts. To study how a data-driven intervention can support a learner in planning, monitoring execution and reflecting I choose academic learning and maintaining one's healthy lifestyle by physical activity as the two scenarios to execute SDS. With that as the research objective, we need to answer the research question How to collect, analyze and visualize learning and health logs together to support self-direction skill of students? To seek answer, the proposed work takes an interdisciplinary approach and applies methods from Learning Analytics (LA) and Quantified Self to log individual's learning and health data, analyze it and interpret that from the theoretical perspective of Self-Directed Learning (SDL) (Loyens et.al. 2008). Synthesizing the models of SDL, we came up with our DAPER (data-analysis-planning-execution-reflection) model to conceptualize the process of SDS execution and acquisition. To initiate, I adopted our Kyoto University group's LA framework and implemented infrastructure that supports connecting various learning logs across e-learning platforms (Flanagan and Ogata, 2017). The present work (Majumdar et.al. 2018) further extends that framework to include health logs from wearable and mobile devices. Based on our DAPER model, we designed and developed Goal Oriented Active Learner (GOAL) system to synchronize-visualize-analyze multisource data regarding student's learning and physical activities (see overview in Figure 1). We called for pilot users who would help in design feedback of both the intervention and the application. Fourteen participants joined in for the program and we had monthly interactions as a part of the pilot need and context analysis. Synchronous logging of learner's learning and physical activities that the GOAL project affords, shall generate a data poll that potentially opens further research opportunities at the intersection of LA and QS research. There is an increasing need of actionable data in Society 5.0, across domains of business, health care and even in education. While many consider a learner centric analytics model in education, there is still no framework which focus on supporting self-direction skills of students considering their health and learning activities together. I plan to study the interactions with the GOAL system to formulate future research questions to understand the interplay of data visualization, technology affordances and acquisition of self-directedness.

In this paper,-book reading patterns by using Markov Chains (MCs). We used click-stream data of 236 students while they read 7 different contents shared by the instructor across different weeks of the course. To analyze reading patterns, we first clustered students independently based on their interaction with each content. We grouped students in None, Low, Medium, and High clusters. Then by using MCs, we calculated cluster transition probabilities between different contents. We also visualized these patterns and applied a patterns. Results revealed that students are likely to follow the same reading patterns across the semester. In other words, if a student reads less in the first content, s/he is likely to read less during the rest of the semester. We also found that transition data could be used to behaviors. The developed model can be used to plan an intervention system for at-risk students. Visualization of these transitions may help a teacher to understand how well students use contents.

E-book readers support users to create learning footprints in many forms, it also allows instructors to update their documents in the e-book reading system. However, e-book users often face problems when trying to find the learning footprints they made in a new version document. In this paper, we deal with how to determine similar pages for learning footprints transferring across versions within an e-book reader in a coursework scenario. We propose an algorithm include Diff method and Transfer method to transfer learning footprints across versions based on page image similarity comparison, and we also try to find an optimal threshold for similar pages determination. After that, we prepare some data for testing and then analyze how well can this algorithm address the problem and what is the optimal threshold for similar pages determination, and the analysis results will be presented.

There has been much research that demonstrates the effectiveness of using ontology to support the construction of knowledge during the learning process. However, the widespread adoption in classrooms of such methods are impeded by the amount of time and effort that is required to create and maintain an ontology by a domain expert. In this paper, we propose a method to automatically generate a contents model by analyzing learning materials with the aim of supporting the construction of knowledge structures. A map of the keyword nodes is constructed by applying text mining techniques to find the important words and phrases and their relations contained within the learning materials. The process retains links between the nodes and the original learning materials, and it is therefore possible to recommend and rank sections that cover a concept contained within the contents model map.

Learning context has evident to be an essential part in vocabulary development , however describing learning context for each vocabulary is considered to be difficult. In the human brain, it is relatively easy to describe learning contexts using pictures because pictures describe an immense amount of details at a quick glance that text annotations cannot do. Therefore, in an informal language learning system, pictures can be used to overcome the problems that language learners face in describing learning contexts. The present study aimed to develop a support system that generates and represents learning contexts automatically by analyzing the visual contents of the pictures captured by language learners. Automatic image captioning, a technology of artificial intelligence that connects computer vision and natural language processing is used for analyzing the visual contents of the learners' captured images. A neural image caption generator model called Show and Tell is trained for image-to-word generation and to describe the context of an image. The threefold objectives of this research are: First, an intelligent technology that can understand the contents of the picture and capable to generate learning contexts automatically; Second, a leaner can learn multiple vocabularies by using one picture without relying on a representative picture for each vocabulary, and Third, a learner's prior vocabulary knowledge can be mapped with new learning vocabulary so that previously acquired vocabulary be reviewed and recalled.

The breakthrough of information technology has accelerated the evolutionary change in teaching and learning methodologies. In particular, pervasion of high-efficiency smartphones has raised the potential to generate a new learning environment called seamless learning, which has been drawing much attetions from researchers in pedagogy of any domains. However, career education using information technology is still in the stage of emergence. There are some reports on ICT implementation to career education such as portal sites for students' career support, the use of ePortfolio in career education, e-Learning in career development for university students and e-mentoring for career development. But no such learning system using seamless mobile learning technologies to enhance career education for international students has been developed yet. The Japanese government, in 2016, declared "Japan Revitalization Strategy 2016". It includes the increasing of the number of foreign workers who gain employment in Japan after graduation. They set the goal from 30% to 50% of the international job hunting students find jobs in Japan. Therefore, career education for international students has become an urgent issue to tackle with in Japan. In fact, many universities in Japan have started providing international students with career education such as business Japanese, business communication and career design. Since Japanese job hunting process is very unique, most foreign students have anxieties about it. According to the survey conducted by the authors, the top two anxieties that international students had about job hunting in Japan were (1) language-related anxieties: writing CVs and entry sheets (writing skill) and job interviews (listening and speaking skills) and (2) an anxiety about how to get information to find a job. There are many terms used in job-hunting processes, which are so rarely used in daily conversation that even advanced learners of Japanese are yet to learn. The survey result also showed that more than half of the questionees selected "I don't know how to get information". It means that it is very important to convey necessary and useful information to international students who are eager to find jobs in Japan. The objective of this study is to propose an effective career support system to get rid of the above-mentioned two anxieties. Our ultimate goal is to contribute to the enhancement of their employment rate in Japan.

This paper describes an automatic quiz generation system to support memory retention utilizing digital textbook logs as well as to reduce teachers' burden to create quizzes. An experimental was conducted to examine whether our automatically generated quiz system more effective in learners' learning achievement than teacher-created quizzes. Twelve international students participated in the evaluation experiment. The result showed that our proposed system and teacher-created quizzes were equivalently effective. A correlation analysis was conducted in order to find the correlations among learning achievement, the number of quizzes and each variable in a questionnaire. It was found that the number of the quizzes and their learning achievement had strong positive correlation.

Seeking for knowledge is one of the most important problems that learners frequently face during their learning process. In this research, a computer supported collaboration learning in ubiquitous computing environment is designed and implemented. This environment is called Perkam (personalized knowledge awareness map). Perkam allows the learners to seek for and share knowledge, interact, collaborate, and exchange individual experiences. This system recommends the appropriate educational materials and peer helpers. The knowledge awareness map visualizes the relative distance between the learner's request and location from one side, and the suggested educational materials and peer helpers from the other side. This paper focuses on the design and the implementation of the knowledge awareness map which is personalized according to the learner's interest and location

Among the possible forms of test, open-ended question has a non-replaceable role in assessing high-level thinking in science education. However, teachers usually hesitate to give this type of tests because of the grading efforts involved unless the grading can be processed automatically by the computer. Recently, there has been much research on automatic text processing in the area of language learning and writing [1] and science education [2].

Abstract: Ubiquitous learning is expected as an innovative learning that can produce high learning effectiveness. In this study, we propose ubiquitous learning support as the bridge between a classroom lecture and e-Learning. This ubiquitous learning support seamlessly connects the lecture and the e-Learning by means of personalization and aims at increasing the learning effectiveness synergistically. We developed a prototype system that performs the personalization.

Abstract: In our previous works, we developed a system named SCROLL in order to log, organize, recall and evaluate the learning log. However up to now, we just use an active mode to record logs. This means that a learner must take a capture of learned contents consciously and most of learning chances be lost unconsciously. In order to solve this problem, we started a project named PACALL (Passive Capture for Learning Log) in order to have a passive capture using SenseCam.

Abstract Authoring and On-line publishing systems attempt to support the learner fs design processes. However, typically the learner fs activities are confined to searching, selecting and reading. In analyzing the role of technology in the learning processes, we conclude that top priority must be given to the construction of infrastructure that supports real communication and cooperative learning processes. Achieving this aim will allow us to properly harness the technology fs potential.

Abstract: In this paper, we discuss potential effects of framing, a pedagogical strategy used by some teachers, with the view of implementing it in an intelligent tutoring system. The process of framing a learning activity, in our case problem solving, consists of having the activity in between a pre-action (or priming) phase and a post-action (or reflective) phase. We also describe an evaluation study where the experimental and control groups participated in a framed and non-framed learning session respectively.

However, in an organizational use there are some problems:(1) the user are reluctant to offer his/her personal details because they are private information;(2) since this system only supports the user in finding candidate partners, the ...

This paper describes an on-line mark-up-based composition learning environment system called CoCoA (Communicative Collection Assisting System). It allows students and teachers to exchange marked-up documents via Internet, and its environment is very similar to a real world one in which people use pen and paper. In order to record and exchange corrected compositions with marks and comments, this paper proposes CCML (Communicative Correction Mark-up Language), which is based on SGML (Standard Generalized Mark-up ...

Abstract While corpus‐based studies are becoming now a new methodology in natural language processing, second language learning seems to be an interesting potential application too. In this paper, we are primarily concerned with the acquisition of collocational knowledge from corpora to use it in the language learning process. We present an efficient method for extracting collocations from corpora which uses the cost criteria measure and a tree‐based data structure. We also propose a bilingual collocation concordancer, a tool ...

Abstract The continuous development of wireless and mobile technologies has allowed the creation of an additional platform for supporting learning, one that can be embedded in the same physical space in which the learning is taking place. This paper describes a computer supported ubiquitous learning environment for language learning, called LOCH (language-learning outside the classroom with handhelds). In the environment, the teacher assigns field activities to the students, who go around the town to fulfil them and share their ...
