The use of computers in the writing classroom changes the actual activities used in class, adapting some present activities and creating new paradigm activities, and also changes the arrangement of the classroom, forcing a radical rethinking of spatial design. The computer classroom is not a passive room, one where information goes out from the teacher to passive receptors; it is an active room where the information flows from writer to computer to readers in the room or on the network. Computers in the classroom change the location of authority, directing focus away from the teacher and the chalkboard and onto the screen, onto the text generated on the computer. In this setting, the teacher acts as facilitator, helping the information flow. Finally, computers in the classroom change the way teachers teach, encouraging veteran teachers to reconsider old ways of teaching composition while they cope with the new technology. (Two appendixes containing illustrations of computer classroom designs and a capsulated comparison between the traditional and computer classrooms are attached.) (KEH)
