The University of Pennsylvania's Perelman School of Medicine is following in the footsteps of medical programs at Yale and Stanford Universities by providing first- and second-year students with iPads, MedCity News reports. The program is looking both to save on paper costs and improve access to course materials. According to The Daily Pennsylvanian, the effort could help replace more than 3 million sheets of paper annually. Some faculty, according to the Pennsylvanian, also are excited about the prospect of being able to update course materials on the fly.
