Which of the following sequences correctly reflects the development of teaching support systems in Indian higher education?

The correct developmental sequence of teaching support systems runs from aural-oral, to visual, to audio-visual, and finally to information and communication technology based systems.

Teaching began with the aural-oral mode of the spoken word and listening in the earliest classrooms.

Visual aids such as print, charts and the blackboard followed to reinforce spoken instruction.

Audio-visual media combining sound and image came next, before the arrival of technology-based systems.

Placing audio-visual or technology first, as other sequences do, reverses the actual order of development.

Each new medium built upon the earlier ones rather than fully replacing them.
