The strength of a knowledge component is a continuous metric of how well it has been learned. As a knowledge component strengthens, its retrieval speed increases, moving toward fluency and increased long-term retention. As its strength is increased, retrieval of the knowledge component require less cognitive demand and thus yield more automaticity, leaving more cognitive headroom for learning other, often more complex, knowledge components.
