基于认知负荷理论的优质教学类PPT设计探析

Analysis of PPT Design for High-quality Teaching Based on Cognitive Load Theory

对于线上和线下教学,PPT课件是大多数课程的必备辅助工具。良器在手,需用之有道。提高设计和制作PPT课件的能力成为很多教师提升教学水平的途径和需求之一。分析目前PPT课件的常见问题和原因,从信息传递及加工过程、容量有限原则和图示理论三方面阐述了认知负荷理论,结合认知负荷理论探究了优质教学类PPT设计原则,基于多通道的优化选择、信息协作的优化,给出了对应的PPT设计技巧,以及线上线下课程的PPT实例。只有从“学”的角度出发、符合认知规律的PPT才是优秀的PPT,才能辅助教学,成为提升教学效果的助推器。

For online and offline teaching,PPT courseware is a necessary auxiliary tool for most courses.A good tool should be used in the right way.Improving the ability to design PPT courseware is one of the ways and needs for many teachers to improve their teaching level.This paper first analyzes the common problems and the reasons in the PPT courseware making,and then expounds the cognitive load theory from three aspects:the information transmission and the processing process,the principle of limited capacity,and the graphic theory.Finally,the PPT design principles of high-quality teaching are discussed combined with the cognitive load theory.Based on multi-channel optimization selection and information collaboration optimization,the corresponding PPT design skills and PPT examples of online and offline courses are given.Only from the perspective of“learning”and in line with cognitive law can an excellent PPT courseware be made,which can assist teaching and become a booster to improve the teaching effect.
