| Outline of Final Research Achievements |
In this study, the IR system that is useful for university faculty and staff in supporting students has been investigated. We developed an early alert system, or ‘Risk Detector’ (hereafter RD), to identify at-risk students before their potential risks become aware and to prevent the students from dropouts and holdovers. RD was expected to pinpoint high risk students with the machine learning method called Soft Margin Support Vector Machine and to indicate a list of metrics of each student as well as the prediction of dropout.
After feeding actual students’ data into the RD, its accuracy rate of prediction was 93%, which meant it provided highly reliable results of discriminant analysis and reasonable precision. In addition, RD was recognized trustworthy by faculty members who assessed it. On the contrary, poor UI and intelligibility of each value on RD were pointed out and discussed as future issues.
