The document discusses different types and levels of knowledge. It defines factual, conceptual, and procedural knowledge based on Bloom's taxonomy. Factual knowledge involves basic elements and details, conceptual knowledge involves relationships among ideas, and procedural knowledge involves skills and methods.

Procedural knowledge similarly ranges from recalling steps to demonstrating strategies. The document provides examples to illustrate the differences between knowledge levels.
