What is the concept of "cognitive load" in education?

Cognitive load refers to the amount of mental effort being used in the working memory. In the context of education, it relates to how much information is held in the mind at any given time while learning or problem-solving. When cognitive load is optimal, learners are better able to process and comprehend new information because their working memory is not overwhelmed.

This concept is crucial for designing effective teaching strategies, as it helps educators understand how to present information in a way that aligns with the limited capacity of working memory. By managing cognitive load through techniques such as breaking down complex tasks or using visual aids, educators can enhance students' learning experiences and improve retention of information.
