Aim To evaluate online elective courses at Croatian medical schools with respect to the virtual mobility of national teachers and students and virtual team collaboration.

Methods A student-centered virtual learning environment developed within the framework of the European Union Tempus Programme allowed national educational services to design and deliver online undergraduate elective courses. Three online elective courses were created for second-year medical students of four Croatian medical schools by using Moodle, an open-source learning management system. The courses supported problem-, project-, and decision-based learning and required students to work in small collaborative teams using problem-solving and decision-making activities. The purpose was to foster teamwork and produce better outcomes than those potentially achieved through individual work. We evaluated the results of these online courses on the basis of the course test results and students’ evaluation questionnaires.
