How to check your study history so far

Overview of New Services⚫Background and Objectives• In accordance with the ”Policy for Utilization of Education and Learning Data”, Tohoku
University obtains ISTU/DC usage logs.
• Accumulate the above logs in MongoDB as LRS (Learning Record Store)• However, a system to easily view the data was not yet established, and teachers could notdirectly check the learning activities of each course.

-> We established the system to overview student learning activities (activitylogs on ISTU) in each course on ISTU/DC. Can be checked from a browser*This system is only guaranteed to work on Google Chrome.

⚫Feature• Can check ISTU/DC operation history (number of clicks per menu) per week/student• Allows selection of learning behaviors to focus on• "Viewed Course Home", "Clicked (some kind of) Submit button", "Viewed/DLed a file (document)", "Viewed aquiz", "Used an external tool (Panopto, MATLAB Grader, WeBWorK, etc.)"• Color coding is available by setting a threshold (students/week below the threshold are displayed in red)
• Excluded weeks (weeks off due to major holidays or class substitutions) can also be set⚫Application Examples• Detection of low activity students• In particular, students whose activity levels have dropped since the middle of the semester.
• e.g., students who start to lose steam in the middle of the semester (e.g., after consecutive holidays) can beidentified.
