Using the Open Learning Initiative (OLI)

Students were struggling in a college course and the instructor couldn’t figure out why. I used data from computer logs to determine where students ran into trouble and investigated the reasons why these sections produced less learning. To improve the course, I designed a series of intelligent tutors that would appear in these low-performing sections. These tutors present problems to students and check their understanding of specific ideas and their mastery of specific skills. Students who didn’t understand the material or master the skill were assisted by the tutor with hints and feedback as the student worked through the problem.
