skills he had to learn were the art of compromising and reciting poetry and the gift of wisdom. One day Finn was sent to a wise old man who lived by the River Boyne. For seven years he had been trying to catch the sacred Salmon of Knowledge, because it was believed that the first to taste this salmon would get all the wisdom of the world. On Monday Finn caught the salmon but should give the first piece to the old man. Finn agreed and began cooking the salmon over an open fire. When Finn was going to turn the salmon over cook it on the other side, he burn his thumb on its hot scales and immediately put his thumb into his mouth to cool it.

The scene in a cavernous buildingatop a forested hill here resembles a brainy, free-form summer camp, or a loft where twentysomethings meet to pursue esoteric dreams. It does not look like the usual notion of college.
A few Lehigh University students turn out prosthetic hands on a 3-D printer. Yards away, another group studies the breeding habits of endangered fish darting around wading pools, and yet another pieces together a film about a Polish poet. Most of the students here are pursuing their own projects — about 30 in all — and finding their own way, with little faculty input and with nothing more at stake than testing their own ambition, skills and curiosity.
“We got a group together and said what we wanted to do, and the administration just said, ‘O.K., ask for any equipment or advice you need,’ ” said Colleen Perry, who is studying bioengineering. “We’ve definitely made mistakes, but it’s probably the first time in our lives that we’re not getting a grade and we don’t have anyone telling us what to do.”
Lehigh first tried what it calls its mountaintop program on a smaller scale last summer, combining elements that scholars of education have advocated for years — research, work experience and independent, long-form projects. Proponents say such hands-on approaches not only reinforce what students learn, they also foster innovation, collaboration and persistence.
Some colleges have expanded those
practices, but the going has been slow. The annual National Survey of Student
Engagement shows that by the time they graduate, fewer than half of college
students have done internships or some other kind of field experience, fewer
than half have done a senior thesis and just 23 percent have done research with

So what Lehigh is trying, she said, “is pretty interesting.”
