Which one of the following four teaching methodologies followed by four different Science teachers for teaching the topic 'Air Pollution' is most appropriate? Options: (a) Asking the students to read the topic from the textbook loudly and explaining the meaning of concepts/terms (b) Dictating the answers to all the questions in the exercise after completing the topic (c) Showing a documentary film on "Air Pollution" to the students (d) Asking the students to collect air samples before and after Diwali, study their quality and tabulate the findings ✅ Correct Option: (d) Asking the students to collect air samples before and after Diwali, study their quality and tabulate the findings Explanation: Option (d) is correct because it promotes experiential learning, active participation, and scientific inquiry. Students are involved in collecting real data, analyzing results, and drawing conclusions, which strengthens understanding of air pollution and its impact on the environment. Options (a) and (b) are passive, teacher-centered methods. Option (c), showing a documentary, is better than lecture but still does not involve hands-on engagement. Field-based and practical experiments encourage critical thinking, observation, data handling, and problem-solving skills. Students understand concepts deeply when they experience real-life environmental changes firsthand. This approach also fosters responsibility, analytical ability, and environmental awareness, aligning with PPSC expectations for practical, activity-based teaching. 10 PPSC-Related Facts: 1. Experiential learning improves conceptual understanding. 2. Students learn by doing. 3. Hands-on work enhances retention. 4. Field experiments promote observation skills. 5. Encourages problem-solving and reasoning. 6. Builds environmental awareness. 7. Students develop data-handling skills. 8. Promotes inquiry-based learning. 9. Collaboration in experiments enhances social skills. 10. Aligns with constructivist pedagogy and child-centered teaching.
