Step 1: Understanding the Concept:
Experiential learning methodologies in extension education: method demonstrations ('learning by doing' 'seeing is believing') directly impart psychomotor physical skills (e.g., net making, hypophysation injection).
Step 2: Detailed Explanation:
In extension education and training pedagogical methodologies:
1. Method Demonstration (B): A group teaching method conducted by the extension worker to show step-by-step 'how to do something' practically (e.g., induced breeding hormone injection, stripping fish, net braiding, feed preparation) followed by hands-on trainee practice. It operates on the foundational principle of 'Learning by Doing' and is the single most effective extension method for acquiring physical skills and psychomotor proficiency.
2. Result Demonstration: Shows the comparative superiority of a new technology over traditional practices ('Seeing is Believing').
3. Lectures Listening: Effective for cognitive knowledge transfer, not physical skill acquisition.
Step 3: Final Answer:
Therefore, skill is effectively acquired by Method demonstration, matching option (B).
