Which of the following is an audio-visual aid? Options: (a) Radio (b) Tape-recorder (c) Television (d) Projector ✅ Correct Option: (c) Television Explanation of Correct Answer (200+ words): Audio-visual aids are teaching tools that involve both sound (audio) and sight (visual) to enhance learning. These aids help students understand concepts more clearly by engaging more than one sense at a time. Television is considered a complete audio-visual aid because it delivers sound, moving images, text, and demonstrations simultaneously. Television makes learning interesting, effective, and realistic. Educational programs, documentaries, and instructional videos shown on television help students visualize abstract concepts and real-life situations. This leads to better attention, comprehension, and retention of information. Compared to audio-only aids like radio or tape recorders, television has a stronger impact on learning because it combines both hearing and seeing. A projector, although useful, is mainly a visual aid unless combined with sound systems. Television is widely used in distance education, teacher training, and classroom instruction. Educational channels and recorded lectures further enhance its usefulness. According to educational psychology, learning becomes more effective when multiple senses are involved, which is why television plays a vital role as an audio-visual aid. 10 Related Facts (PPSC-Oriented): 1.
