Step 1: Understanding the Concept:
Extension education is an applied science designed to bring about desirable changes in the behavior (knowledge, skills, and attitudes) of people.
To ensure the success of these educational activities, extension professionals follow established guidelines based on scientific research and field experience.
Step 2: Detailed Explanation:
Let us analyze the definitions of the given terms in extension education:
1.Philosophies (A): These are the core values, beliefs, and vision statement that guide the overall direction of extension (such as "helping people help themselves").
2.Principles (B): Principles are fundamental truths or guidelines developed from universal facts.
When applied, they serve as a practical guide for extension workers, ensuring the success of their teaching and demonstration programs.
Examples include the principle of "learning by doing" and the "principle of interest and need."
Thus, (B) is the correct option.
3.Objectives (C): These are the specific, measurable goals or endpoints toward which extension activities are directed.
4.Scope (D): This refers to the boundaries or areas of influence within which extension activities operate.
Step 3: Final Answer:
The term that denotes guidelines developed based on universal truths to facilitate successful extension activities is Principles.
