Notre Dame’s engineering dean, Peter Kilpatrick, will be the first to concede that sophomore and junior years, which focus mainly on theory, remain a “weak link” in technical education. He says his engineering school has gradually improved its retention rate over the past decade by creating design projects for freshmen and breaking “a deadly lecture” for 400 students into groups of 80. Only 50 to 55 percent of the school’s students stayed through graduation 10 years ago. But that figure now tops 75 percent, he says, and efforts to create more labs in the middle years could help raise it further.
“We’re two years into that experiment and, quite honestly, it’s probably going to take 5 to 10 years before we’re really able to inflesh the whole curriculum with this project-based learning,” Dean Kilpatrick says.
No one doubts that students need a strong theoretical foundation. But what frustrates education experts is how long it has taken for most schools to make changes.
The National Science Board, a public advisory body, warned in the mid-1980s that students were losing sight of why they wanted to be scientists and engineers in the first place. Research confirmed in the 1990s that students learn more by grappling with open-ended problems, like creating a computer game or designing an alternative energy system, than listening to lectures. While the National Science Foundation went on to finance pilot courses that employed interactive projects, when the money dried up, so did most of the courses. Lecture classes are far cheaper to produce, and top professors are focused on bringing in research grants, not teaching undergraduates.
