Intrinsic load refers to the inherent difficulty or complexity of the material being learned. It is determined by the nature of the content itself and the learner's prior knowledge. For example, a beginner learning basic math concepts will experience a different intrinsic load compared to someone studying advanced calculus. This concept is important in cognitive load theory, which suggests that effective learning occurs when the intrinsic load is balanced with the learner's ability to process information. If the intrinsic load is too high, it can overwhelm the learner, hindering understanding and retention of the material.
