Over winter break, eight Cornell volunteers collaborated with seven students from the Universidad del Magdalena in Santa Marta, Colombia, to teach biology to Liceo Samario high school students. For some time, Prof. Timothy DeVoogd, psychology, has been trying to create international experiences for Cornell students in the sciences. He realized that one way to promote students’ international involvement might be to work with peers in Latin America over winter break. DeVoogd proposed the idea to Carlos Coronado, director of International Relations at the University of Magdalena. Coronado then found a public high school in which 80 percent of its students come from families below the Colombian poverty line, DeVoogd said.
