信息技术环境下学科教学认知负荷超载与卸载研究

Research on overloading and unloading of subject teaching cognitive load under the environment of information technology

Mayer的认知负荷理论对信息技术环境下的学科课堂教学产生了重要的影响。本研究以Mayer的认知负荷理论为基础,结合学科教学设计了信息技术环境下学生的认知加工模型;根据认知负荷理论提出了学科教学认知负荷三种超载形式;明确了学生在选择、组织、整合三个信息加工环节中存在的不同超载类型;针对不同环节中的信息超载现象,提出了导向性原则、双通道原则、分割原则、操作性原则、结构性原则等信息技术环境下的教学卸载原则;应用卸载原则设计了学科教学中的具体实施方案,为信息技术环境下的教学改革提供新思路。

The Theory of Cognitive Load,represented by Mayer,is affecting the subject classroom under the environment of information technology.This paper relies on the Theory of Cognitive Load and designed the cognitive processing model under the environment of information technology by subject teaching.According to cognitive load theory.This paper proposes three overload of subject teaching cognition,puts forward the different style of overloading in selecting,organizing and integrating,and puts forward the principle of unloading：the principle of leading,the principle of double tunnel,the principle of separating,the principle of operation and the principle of structure under the enviroment of information technology.Applying unloading principle to design specific implementation plan in the teaching provides the new idea of teaching reform under the information technology environment.
