认知负荷理论视角下的微课程多媒体课件设计

The Multimedia Courseware Design of Micro-lecture Based on the Cognitive Load Theory

微课程以其短小精悍、随时随地的特性渐渐步入教育领域。与此同时，如何设计微课程的多媒体课件，使其在短时间内充分展现知识内容，并符合学习者的学习规律，成为微课程设计的焦点。从认知负荷理论视角，分析了学习过程中的认知负荷情况，并结合大量实例，实践了降低原生性认知负荷、无关性认知负荷，以及提高相关性认知负荷的策略和方法，实现了认知负荷在微课程课件设计中的导向性作用。

Micro-lecture with its short and everywhere feathers gradually walks into the educational domain. Simultaneously， the design focus turns to how to design the courseware of micro-lecture， such as how to demonstrate the content in such a short time. And all of them should be accordance with the learners’ learning rules. Based on the cognitive load theory， this paper analyzed the cognitive load situation in the learning procedure; practice the methods of reducing intrinsic cognitive load， extraneous cognitive load， as well as the methods of increasing the germane cognitive load. The cognitive load theory plays a guidance role in the micro-lecture design.
