Question

Three of the following extension teaching methods belong to the same category. Choose the odd one out.

• A. Bulletin
• B. Radio talk
• C. Exhibition
• D. Field trip

Hint:

Remember the three contact categories in extension education:
- Individual (one-on-one).
- Group (medium-sized, interactive, e.g., field trips, demonstrations).
- Mass (large-scale, broad reach, e.g., radio, print, exhibitions).

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Extension teaching methods are classified into different categories based on the number of people they are designed to reach:
1. Individual contact methods (e.g., farm visits, personal letters).
2. Group contact methods (e.g., group discussions, field trips, demonstrations).
3. Mass contact methods (e.g., radio talks, agricultural bulletins, exhibitions, television).

Step 2: Detailed Explanation:
Let us analyze the classifications of the four methods listed in the options:
- Bulletin (Mass Contact):
A printed publication used to share information with a large, dispersed audience.
- Radio talk (Mass Contact):
An audio broadcast that can reach thousands of farmers simultaneously across a wide geographic area.
- Exhibition (Mass Contact):
A large-scale public display designed to share technologies and information with a large crowd.
- Field trip (Group Contact):
A planned educational visit where a specific group of farmers travels to a research station or successful farm to observe new practices.
Because it is designed for a smaller, defined group rather than a mass audience, it is classified as a group contact method.
Therefore, while Bulletins, Radio talks, and Exhibitions are mass contact methods, the Field trip is a group contact method, making it the odd one out.

Step 3: Final Answer:
The field trip is a group contact method, making it the odd one out among the listed mass contact methods.
Thus, the correct choice is (D).
