Why doesn every JHSPH OCW course offer video lectures?
Although video lectures are useful for students, JHSPH OCW does not include video lectures in every course for several reasons. First is the issue of bandwidth. We are very much focused on making JHSPH’s course materials as accessible as possible to users all over the world, including the developing world. If we were to start depending on the video component as the key element of every JHSPH OCW course, we would be excluding a large portion of the JHSPH OCW audience who are still surfing the Web on 28K modems. We are very sensitive to the fact that they would never be able to download the videos.
