Learning Management System (LMS) has played important roles to support teaching and learning from the effective course management to the communication and collaboration between an instructor and students, and among students. Further, web log files that instructors and students leave in LMS not only explain their online learning patterns but also enable to provide a useful treatment and learning guidance to students. Use of big data such as the log files, technics of educational data mining (EDM) and provision of appropriate treatments throughout the visualized dashboard have been attractively recognized among researchers and practitioners who connect them with smart learning. This study includes four phases. First, we investigated how students in a large university used Moodle LMS in their virtual campus and how they perceived the needs of learning analytics dashboard. Second, based on the preliminary investigation, we designed and developed a visual dashboard presenting students’ online learning patterns. Third, we conducted a usability test in order to extract design implications for the effective dashboard. Fourth, after implementing the dashboard treatment to students, we surveyed the conformity between their perceptions and tracked online behaviors, the level of understanding, and perceived usefulness on the dashboard. While participants of this study revealed high level of understanding and fair level of conformity, their perceived usefulness was relatively lower. Throughout the survey results as well as the usability test which involved stimulated recall methods as well as interview we learned students had different levels of understanding on six major contents including total login time, login frequency, login regularity, visiting on board, time spent on board, and download of learning materials. Based on the implications from the experiment and survey results, multiple directions to improve the usefulness of dashboard were reviewed and discussed in conclusion. This study is meaningful since the developed dashboard is expected to make an advancement of LMS by adding such learning analytics dashboard in the system.
