Semantic Interpretation

* **High Value (> 0.5)**: A curriculum "leap" or bypass. Students are figuring out this skill without needing the prerequisites you specified. This implies your theoretical graph (DAG) might be incorrect, or the skill relies heavily on unmodeled outside common-sense knowledge. * **Low Value (< 0.2)**: A strict prerequisite. Students who lack the prerequisite essentially have zero chance of leaping or guessing their way into mastering this skill.
