摘要
认知负荷是影响学习效率和效果的重要因素,E-learning环境的设计会对学习过程中的认知负荷水平产生影响。导致E-learning环境中认知超载的原因主要集中在界面设计和内容设计两个方面。在界面设计上,复杂的导航设计容易引起学习者"迷航",色彩风格的不统一会造成学习者对学习的焦虑和不适;在内容设计上,大量的学习资源可能会消耗学习者有限的注意力,过量的冗余信息会分散学习者的注意力。为减少认知负荷,促进学习者的信息存储、提取和加工,在界面设计时,应注意做到导航设计清晰明确、交互界面设计符合视觉心理学标准;在内容设计时,信息表征要注意多样化,并添加标注说明,信息切割要恰当,信息加工设计要提供各种认知工具、学习指南和监控、交流合作空间,并为初学者提供样例。
Cognitive load is one of the most important factors influencing learning efficiency and effect while E - learning instructional design may impinge on cognitive load. Students may be cognitively overloaded as a result of inappropriate interface design and content design . In terms of interface design, students may get lost in confusing navigation and become distressed due to inconsistency in colour and style. In terms of content design , excessive resources and redundancy in information may waste students' limited time and energy as well as distract their attention . Therefore , navigation design needs to be clear and concise and interface design in line with visual psychology standards . In regard to content design , information representation should be diversified and tagged ; information should be appropriately chunked and proximately linked ; and cognitive tools , learning guide and monitoring , interaction and collaboration space need to be provided to facilitate information processing with samples for beginners .
