The concept of 'cognitive load' refers to the total amount of mental effort being used in the working memory. In educational settings, instructional designers often aim 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 working memory capacity. However, germane load, which is the effort devoted to processing and understanding the material, is beneficial. Recent research suggests that by reducing extraneous load through clear formatting and scaffolding, educators can free up mental resources for germane processing, thereby enhancing knowledge acquisition. Yet, critics argue that overly simplified presentations may reduce the depth of processing, leading to superficial understanding. Thus, the optimal balance remains a subject of debate.
❓ According to the passage, what is the main purpose of reducing extraneous load in instructional design?
A. To increase the intrinsic complexity of the material
B. To allow more mental resources for deep processing and understanding
C. To eliminate all cognitive load from the learning process
D. To encourage learners to memorize information more quickly
✅ 正确答案
To allow more mental resources for deep processing and understanding
