📖 Reading Passage

The concept of 'cognitive load' refers to the total amount of mental effort being used in the working memory. In educational settings, instructional design often seeks to manage cognitive load to optimize learning. According to 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 capacity. However, germane load, which involves the processing and construction of schemas, is considered beneficial. Research suggests that reducing extraneous load, for instance by using clear diagrams or eliminating redundant information, can free up mental resources for deeper understanding. Nevertheless, some studies argue that over-simplification may reduce germane load, leading to superficial learning. Thus, designers must balance simplicity with sufficient challenge to promote effective schema acquisition.
