In CAI, the computer delivers instructional material in a structured, programmed form. It can present explanations, ask questions, check responses and show hints or feedback immediately. This allows learners to work at their own pace and get individual practice that might be difficult in large classes. Thus, the computer functions mainly as an automated teaching and practice device, not as an administrator or builder.
Option A:
This option correctly identifies that CAI uses software to emulate some aspects of a tutor. It organises content into small frames, provides drill and practice and can adapt the sequence based on learner performance. The focus is on supporting learning activities rather than on institutional management.
Option B:
Admission policies and administrative decisions are made by human authorities, often with the help of management information systems. CAI is concerned with instructional delivery, not with macro-level governance.
Option C:
Construction of buildings is a civil engineering task and unrelated to the instructional role of computers. While ICT tools may help in design, CAI specifically refers to teaching applications.
Option D:
High-stakes examinations may use computers for delivery, but that is more closely related to computer-based testing than to CAI. CAI emphasises interactive learning modules, not mass examination administration without human oversight.
