I overheard some students the other day complaining that their teacher did not use ppts at all and that they "had to take notes the old fashioned way." The students were upset that they couldn't just print out the ppts and have instant notes. The younger generation of students, it seems, has come to expect this type of media in classes. It's a balance between satisfying their preferred media for learning and changing things up a bit by using white board, demos, etc. It's challenging to satisfy all the students in class with their preferred delivery of media, especially when there is a tremendous variety in age.
