Purdue has issued a press release stating that a data-mining and analysis software program they developed has increased six-year graduation rates by 21.48 percent. The software, called Signals, looks at students’ online academic behaviors, combines this information with demographic information about the student, and then displays a simple and intuitive red, yellow, or green signal on the student’s course website to let them know how they are doing in that course. In addition to the visual warning, students also receive messages prepared by the instructors.
