An introduction to using word processing in writing instruction, this report first describes the basic terms and tools used in word processing and then lists the four characteristics of a good word processing program. They are the options to: (1) edit and insert; (2) cut and paste; (3) find and correct; and (4) store and save documents of between 10 and 20 pages quickly and accurately, with a minimum of user error. It then briefly reviews the advantages and drawbacks of several popular word processing programs and computer books, and suggests what skills teachers will need to help students master word processing. The report outlines what the use of word processing will mean for students, such as learning to write in the computer room, and examines how word processing will affect the three essential components of writing--prewriting, writing, and revision.
