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 Sweller's cognitive load theory, learning is hampered when the load exceeds the learner's cognitive capacity. This can occur when information is presented in a complex or disorganized manner, or when the learner must process multiple interacting elements simultaneously. Strategies such as segmenting information, using worked examples, and reducing extraneous content have been shown to alleviate excessive load. However, recent studies suggest that a certain level of desirable difficulty, or productive struggle, may enhance long-term retention, challenging the notion that cognitive load should always be minimized. Thus, effective instruction may require a balance between reducing unnecessary load and introducing challenges that promote deeper processing.
❓ 根据文章所述，近期关于认知负荷理论的研究主要意味着什么？
A. A) 认知负荷应始终被最小化，以确保最佳学习效果。
B. B) 引入一定程度的难度可能有助于提高长期记忆，因此最小化负荷并非总是理想之选。
C. C) 工作示例无效，因为它们增加了认知负荷。
D. D) 认知负荷理论已被最新研究彻底推翻。
✅ 正确答案
B) Introducing some level of difficulty may improve long-term memory, so minimizing load is not always ideal.
