This article presents the Simmons World Challenge curriculum, an intensive, interdisciplinary program for sophomore undergraduate students that emphasizes student-directed collaborative learning and skills development. The authors present the curricular approach and assessment outcomes, and they relate this program to goals of the AAC&U's Liberal Education and America's Promise (LEAP) Initiative.
