At which level does a student perceive that a behavior has worth or value?

The correct choice focuses on the Affective Domain, specifically the stage of valuing. In this context, valuing refers to the level at which a student begins to recognize the worth or importance of certain behaviors, attitudes, or beliefs. This includes understanding the significance of those behaviors not just superficially but also on a deeper emotional level.

In this stage, students actively engage with their feelings and opinions, allowing them to appreciate the consequences of those behaviors in both personal and social contexts. This is crucial for the development of a well-rounded individual who can make informed decisions based on their values.

The other choices reflect different levels or domains of learning. Organizing within the Affective Domain involves synthesizing values and developing a coherent value system, while comprehension in the Cognitive Domain refers to understanding information, which doesn't directly address the intrinsic worth of behavior. Naturalization in the Psychomotor Domain describes the phase of mastering physical skills and does not relate to the value perception of behavior. Each domain plays a distinct role in learning, but valuing specifically deals with the recognition and appreciation of worth.
