基于认知负荷理论的教学媒体设计

Instruction Media Design Based on Cognitive Load Theory

首先对认知负荷的概念含义、主要观点和分类做简单扼要的论述。认知负荷理论提出了一些能减少学习者认知负荷，提高学习效率，并对教学媒体设计有指导作用的教学效应：分散注意力效应、双重感官效应、独立交互元素效应、元素交互效应及冗余效应。在阐述这些教学效应的基础上，分别给出它们在教学媒体设计中应用的例子。

At the beginning of this paper， we simply discuss the meaning， main point， and classification of cognitive load. Some instructional affection is put forward in cognitive load theory， which can induce cognitive load， promote learning efficiency， and guide the design in instructional media. Based on the discussion in these affection， examples that apply to the design in instructional media are given individually.
