Overview & Description: This theory refers to the total amount of mental effort being used in the working memory.

Key Points:

1. Types of Cognitive Load: Intrinsic (natural complexity of material), extraneous (how material is presented), and germane (deep processing of information).
2. Instructional Design: Helps in designing educational materials to match the learner’s cognitive capacity.

Implications: Understanding cognitive load can lead to better educational strategies and improved user experience in interface design.
