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 Sweller's cognitive load theory, learning is hindered when the intrinsic load (the complexity of the material itself) and the extraneous load (the way information is presented) exceed the learner's capacity. However, recent studies suggest that a certain level of germane load, which involves the mental processes dedicated to constructing and automating schemas, is beneficial. This has led to a shift from purely reducing load to strategically designing tasks that promote schema acquisition, particularly in complex domains like mathematics and science. Thus, the challenge lies not in minimizing all cognitive effort, but in balancing different types of load to enhance deep understanding.
❓ According to the passage, what is the main challenge for instructional designers?
A. To eliminate all forms of cognitive load to avoid overwhelming learners.
B. To increase the intrinsic complexity of material to promote deeper learning.
C. To balance different types of cognitive load to facilitate effective schema construction.
D. To focus solely on reducing extraneous load without considering other factors.
✅ 正确答案
To balance different types of cognitive load to facilitate effective schema construction.
