Unlike an old-school chalk talk, professors who use PowerPoint tend to present topics very quickly, leaving little time to digest the visuals or to take learning-reinforcing notes. Also, profs who use the ready-made PowerPoint lectures that ship with many textbooks tend to come across as, shall we say, less than connected with their material. Then there are professors who just don't know how to use PowerPoint, a problem that is by no means limited to college classes."
