📖 Reading Passage

The concept of 'cognitive load' refers to the total amount of mental effort being used in the working memory. In educational contexts, instructional designers often aim to manage cognitive load to optimize learning. According to Sweller's cognitive load theory, learning is hindered when the intrinsic load (complexity of the material) and extraneous load (how the material is presented) exceed the learner's working memory capacity. However, recent studies suggest that a certain level of germane load, which involves the mental resources dedicated to constructing schemas, is beneficial for deep understanding. Thus, effective teaching strategies should not merely reduce all cognitive load but rather prioritize minimizing extraneous load while allowing sufficient intrinsic and germane load for meaningful learning.
