“Because of iTunes U, I have been able to introduce students and colleagues in China to research on the links between chronic multi-tasking, information overload and stress; discuss research publications and degree programs with students in Europe; and exchange information about the influence of neighborhood design on community levels of physical activity and obesity with students in Australia,” said Professor Stokols, whose Environmental Psychology course enrolls over 170,000 students on iTunes U. “The opportunity to impact so many students who are gaining interest in environmental psychology by taking my free course on iTunes U has been highly rewarding and gratifying for me as an educator and learner.”
