A Study on Predicting Model of Students Leaving Their Majors Using CART Algorithm

  Nowadays most colleges are confronting with a serious problem because many students have left their majors at the colleges. In order to make a countermeasure for reducing major separation rate, many universities are trying to find a proper solution. As a similar endeavor, this paper uses CART (Classification and regression tree) algorithm for the feature analysis and provides predicting model of students leaving their majors. The sample for this study was chosen from a university in Kangwon-Do during seven years (2000.3.1 ~ 2006. 6.30). This study provides values about accuracy, sensitivity, specificity using classification table. The analysis results were very informative since those enable us to know the most important factors such as semester taking a course, grade on cultural subjects, scholarship, grade on majors, and total completion of courses which can affect students leaving their majors.
