Douglas Webber is known as a “numbers guy” at Temple University in Pennsylvania. Webber is a labor economist. Years ago, he met his future wife at a mathematics camp. His latest research offers guidance on how to keep students on target to earn a degree from a college or university. Among his findings: It is important, whenever possible, for college students to complete their degree program in four years. Also, getting a part-time job is probably a good thing to help finance a college education. But too much time spent working on a job makes it less likely the student will graduate. Webber’s latest research suggests that students who are close to dropping out of school will do better financially if they stay with it and find a way to graduate.
