One of the questions that were raised at the beginning of this course is if computer assisted instruction (or CAI) is truly more beneficial than a blackboard or overhead projector. Although it is true that for certain lessons it is just as easy to use the age old blackboard and text books; computers can still over many benefits that “normal” classroom instruction cannot. For example, if your class is studying something such as biology, a textbook cannot show the same illustration such of something such as a heart that a computer can. A computer could show three dimensional, as well as more realistic illustrations of such things as a heart or the anatomy of an animal. A student is much more likely to remember the image of the anatomy of a frog using a computer versus a textbook.
