The topic 'Depletion of Petroleum and Coal' was taught to Section A of a class using multimedia capsule while Section B was taught through diagrams on the Green Board. Students of Section A understood the topic better. This could be due to the reason that Options: (a) Audio-visual aids engage all the senses for better retention (b) Green Board is not a good visual aid (c) Multiple approach is closer to everyday life situations (d) Use of multimedia aids is comparatively more economical ✅ Correct Option: (a) Audio-visual aids engage all the senses for better retention Explanation: Audio-visual aids enhance learning by engaging multiple senses simultaneously—visual, auditory, and sometimes kinesthetic—leading to better understanding and retention. Option (a) is correct because multimedia presentations make abstract concepts like resource depletion more concrete, vivid, and memorable. Option (b) is partially true but too narrow. Option (c) is correct in principle but less specific than option (a). Option (d) is irrelevant; cost is not the factor affecting understanding. Using multimedia aligns with modern pedagogical principles such as constructivism and multiple representations of content. Students can visualize processes, hear explanations, and relate to examples, resulting in deeper learning. 10 PPSC-Related Facts: 1. Multimedia engages multiple senses. 2. Retention improves with visual and auditory stimuli. 3. Abstract concepts become concrete. 4. Learning becomes enjoyable. 5. Supports varied learning styles. 6. Encourages active participation. 7. Enhances understanding of complex topics. 8. Facilitates teacher-student interaction. 9. Aligns with constructivist learning principles. 10. Increases classroom motivation.
