What does cognitive load refer to in a learning context?

Cognitive load in a learning context refers specifically to the quantity of mental effort required in working memory to process information. It encompasses the amount of information that a learner must take in, understand, and apply during the learning process. This concept is crucial because working memory has a limited capacity, and exceeding its limits can hinder learning and retention.

When cognitive load is appropriately managed, learners can effectively absorb new material and construct meaningful knowledge. However, if the cognitive load is too high, it can lead to overwhelm, frustration, and ultimately hinder the learner's ability to make connections or understand concepts fully. Thus, understanding cognitive load helps educators design instructional strategies that optimize learning conditions by minimizing unnecessary load and promoting efficient cognitive processing.
