CAI stands for .............................. .
Computer Assisted Instruction
CAI expands to Computer Assisted Instruction. It is the use of the computer as a teaching medium: the machine presents material, asks the learner questions, evaluates the response and branches to the next step according to that response, so the pace and path adjust to the individual learner.
Its familiar modes are drill and practice, tutorial, simulation, instructional games and problem solving. The common thread in all of them is instruction — the computer is doing part of the teacher's teaching work, which is why the second word is "Instruction" and not any of the alternatives offered.
The three remaining expansions — Computer Assisted Imitation, Computer Arranged Installation and Computer Arranged Induction — are not recognised terms in educational technology; none of them names a teaching mode, and "Computer Arranged" is not a standard collocation at all.
A related term worth separating from it is CAL, Computer Assisted Learning, which stresses the learner's activity rather than the delivery of instruction.
Hence CAI stands for Computer Assisted Instruction.
