摘要
课件作为教学过程中的重要信息载体和知识输出、展示的主要工具,不同的设计会对学生的认知负荷产生不同程度的影响。在教学过程中合理降低学生的认知负荷,避免学生的认知资源被无关信息或解析繁杂信息占用,将学生的认知资源集中于知识本身,对教学效果具有积极的影响。从课件的设计视角研究如何降低学生的认知负荷具有重要的现实意义,本文根据参数化网页曲柄摇杆设计课件的设计实例,基于认知负荷理论,从机构的设计参数可视化、信息关联化及图像信息关联化等方面降低学生在机械原理课程中的认知负荷,提高教学的效能。
As courseware functions as an important information carrier and a major tool to output and display knowledge,the difference in courseware design will exert differentiated influence,to varying degrees,on cognitive load of students.Courseware,which makes reasonable reduction in cognitive load of students so as to free them from irrelevant or additional complicated information and thus focus their cognition on intended knowledge,will play a significant role in teaching effects.Studies,from the perspective of courseware design,into ways to reduce cognitive load of students are of real significance.With case studies into parameterized courseware design for crank rocker,the paper is designed,based on cognitive load theory,to reduce cognitive load of students to mechanical principles and achieve better teaching effects by using visualized design parameters,relevant information and associated image and information。
