Computer-Assisted Instruction IN TEACHING ENGLI

A computer is a "device which performs pre-specified computations on any valid set of input data and delivers results within defined levels of accuracy" (Longley & Shain, 1986, 64). Computer-Assisted Instruction is the "use of a computer as an integral part of an instructional system, with the learner generally engaging in real-time interaction with the computer via a terminal" (Ellington & Harris, 1986, 36).

Nowadays it is hardly necessary to explain what a computer is--at least in the industrially developed countries. Yet, in instruction, mainframes, minicomputers, desktop and even lap computers are used. Yet, interactive instruction is coming of age through television. Yet, computers can be used as a component of an interactive television program. Moreover, CAI (Computer-Assisted Instruction) can be used for group as well as individual instruction. Then, there is the problem of textual vs graphic vs audio-visual presentation modes. Indeed, the latest iteration of CAI has added still pictures to the text, and motion-pictures, and sound, and interaction between computer and learner. Three-dimensional presentation is now appearing on a computer screen near you.

In view of this multimedia interactive process, the question is no longer whether computers teach, but what is the most effective combination of computer-assisted media. After all, Programmed Instr

the full capabilities of this remarkable resource lies in the quality of available educational software" (p. 472). Increasingly, there are good programs. It is up to the teacher to assess CAI programs in terms of how and for whom they are written. Today, "computer-delivered tutorials are used primarily to introduce new information to the learner in a way that closely parallels how teachers and texts often present new instructional content" (Schreck & Schreck, 1991, 473). For reading comprehension and study skill activities, CAI would seem to be well suited. Nevertheless, CAI's forte has been drill and practice exercises from the very start of its use. Indeed, the computer never tires of repeating itself and, if well branch-programmed, it may offer a large number of options should the learner fail in the first offering. Recalling, recognizing, memorizing, and applying information previously communicated through the computer or through classroom and other means, are the strong points of classic textual programs. Multimedia capability can only enhance these advantages. The feedback provided by the computer is likely to surpass that provided by the textbook, the flashcard, or even the busy teacher. CAI is also king in providing i
