Which of the following did Taba classify as a content level?

Taba classified content levels in terms of the structure and organization of knowledge critical for effective learning experiences. The correct choice encompasses key concepts, organizing ideas, and specific facts, which are essential components of her framework. Key concepts serve as the core ideas around which learning activities are centered, while organizing ideas provide a structure to understand those concepts. Specific facts serve to enrich students' understanding by offering concrete examples and details that support broader themes and ideas.

In Taba's classification, this content level aids educators in developing curricula that help students progress from concrete knowledge (specific facts) to more abstract understanding (key concepts and organizing ideas). This approach emphasizes the importance of a structured learning experience that helps students make connections between specific details and overarching ideas, facilitating deeper learning.
