Abstract
For centuries, teachers have been using Audio-visual aids to improve the effectiveness of their teaching. They have relied on such aids as the teacher's voice, the blackboard, pictures, charts, maps and texts material to elucidate, illustrate and clarify ideas and concepts, which by their very nature might have presented some difficulty in terms of students' perception of them. Yes, Educational Technology has made an impact on the formal education system of Trinidad and Tobago but the impact is feeble.
