COIL stands for Collaborative Online International Learning. COIL is a new pedagogical approach that will allow Sophia University students in Japan to connect and learn with students at institutions abroad using ICT tools like Zoom, Google Classroom, Facebook, etc.
Three universities from Japan, Sophia University, Ochanomizu University, and University of Shizuoka, and ten institutions from U.S. participate to (1) provide globally connected educational opportunities, (2) enhance multi-faceted student mobility programs, which incorporate resources from partner institutions and local societies, and (3) contribute toward elimination of educational inequality through COIL for students in developing countries. It is worth nothing that all three universities began COIL initiatives in areas they have particular strengths, i.e., International Education for Sophia, Advanced Japanese education for Ochanomizu, and International Nursing for Shizuoka.
