Cognitive load is important to consider when designing any kind of content. Cognitive load relates to how one generates schema, and the long-term memory associated with the schema. Basically, cognitive load is related to the amount of working memory being used by one's brain to complete a task. The working memory is used right away, long before a memory can even be stored in one's long-term memory. The ultimate goal of any significant learning event is to generate schema, but that cannot be done if the cognitive load reached is either intrinsic or extraneous. Intrinsic cognitive load relates to the difficulty of the task and extraneous cognitive load relates to how to the learning is presented. Both should be considered by instructional designers when designing content and learning environments. Germane cognitive load is optimal as it is directed toward generating schema.
