📖 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 design aims to manage this load to optimize learning. According to cognitive load theory, learning is hindered when the intrinsic complexity of the material, combined with the way it is presented, exceeds the learner's cognitive capacity. Extraneous cognitive load, which is generated by poorly designed instruction, can be reduced by simplifying the presentation, whereas germane load, which contributes to learning, should be encouraged. Research has shown that breaking down complex tasks into smaller steps and using worked examples can significantly decrease extraneous load, allowing learners to focus on schema construction. However, over-simplification may lead to a reduction in germane load, as learners are not challenged enough to engage deeply with the material.
