The concept of 'cognitive load' refers to the total amount of mental effort being used in the working memory. In educational settings, 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 available working memory capacity. Extraneous cognitive load, which arises from poorly designed instruction, can be reduced by simplifying presentations and eliminating irrelevant information. However, germane load, which is the effort devoted to processing and understanding the material, should be encouraged. Recent studies suggest that adaptive learning technologies, which tailor the complexity of tasks to the learner's current level, can effectively balance these types of load, thereby enhancing both comprehension and retention. This has significant implications for curriculum development and the design of digital learning environments.
❓ According to the passage, what is the main purpose of reducing extraneous cognitive load in instructional design?
A. To increase the intrinsic complexity of the material
B. To free up working memory capacity for effective learning
C. To encourage learners to process more irrelevant information
D. To eliminate the need for adaptive learning technologies
✅ 正确答案
To free up working memory capacity for effective learning
