Twenty students from country's leading technological university have spent the last four weeks studying at Rose-Hulman.
The students are getting some hands-on experience in the lab, working on MEMS, or MicroElectroMechanical Systems.
That's the technology in small devices.
Professors say it's a unique opportunity to get so close to that science in action, and the students won't forget what they've learned.
"We're lucky here. We can get the students to practice. This will help them back in Korea. That's not to say there aren't teaching institutions in Korea, the country's full of them. But I don't think they can get this particular experience," said Rose-Hulman professor Dr. Michael McInerey.
Yong Kyu Choi is a senior at the Seoul National University of Technology who's taking part in the Rose-Hulman summer school.
"It's a honor to me and it's so interesting to me so I believe that it's the best memories of my life," said Choi, 23, who's also the leader of the Korean student team.
During their time here, the South Koreans also volunteered at the Booker T. Washington Community Center and clean-up efforts in Henryville.
